This guarantees the continuity and reliability of the test. Furthermore, by setting up the water replenishment component, it can replenish water promptly when the test water level in the tank falls below a preset level, maintaining the water pressure of the test water flowing out of the tank within an optimal range. This is especially important when the test system simultaneously tests at least one constant pressure water supply device and at least one negative pressure-free water supply device; the controllable water pressure conditions ensure the stability of the test process and the accuracy of the test results.

Unless otherwise specified, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Where there is no conflict, embodiments of this application and the various features thereof can be combined with each other, all of which are within the scope of protection of this application.

[0082] To address water pressure issues in high-rise buildings or areas with insufficient water pressure, ensure stable and sufficient water pressure, and improve water quality and comfort, secondary water supply equipment is needed to provide secondary water supply to these areas.

[0083] To ensure the normal operation of secondary water supply equipment, manufacturers need to conduct functional tests on the equipment before it leaves the factory or is put into use. Functional tests include, but are not limited to, electrical control function tests, mechanical pipeline function tests, and operating environment tests.

[0084] In related technologies, staff use a secondary water supply equipment testing system to test multiple secondary water supply devices sequentially, resulting in low testing efficiency and low utilization of the testing system, making it difficult to meet the needs of large-scale production.

[0085] To address the aforementioned technical problems, this application provides a testing system for secondary water supply equipment. Figure 1 A schematic diagram of the structure of the test system for the secondary water supply equipment provided in the embodiments of this application.

[0086] Specifically, please see Figure 1The secondary water supply equipment testing system includes: a water tank assembly 100, which includes a tank body 110 for storing test water; a water replenishment assembly 200 connected to the tank body 110, which replenishes or stops replenishing test water in the tank body 110 when the test water level is lower than or reaches a preset level; a constant pressure testing assembly 300 connected to the tank body 110 and at least one constant pressure water supply device 10; a booster pump assembly 400 connected to the tank body 110 and used to increase the pressure of the test water flowing out of the tank body 110; and a negative pressure-free testing assembly 500 connected to the booster pump assembly 400 and at least one negative pressure-free water supply device 20.

[0087] The testing system for secondary water supply equipment provided in this application embodiment includes a water tank assembly 100 and a booster pump assembly 400. The booster pump assembly 400 is connected to the water tank assembly 100. The water tank assembly 100 can simulate a constant pressure testing environment (simulating water supply from a storage tank), and the booster pump assembly 400 can simulate a negative pressure-free testing environment (simulating municipal water supply). It is understood that the booster pump in the booster pump assembly 400 can be a positive displacement pump, such as a gear pump, screw pump, or vane pump. The booster pump in the booster pump assembly 400 can also be an impeller pump, such as a centrifugal pump or axial flow pump.

[0088] By setting up a negative pressure-free test component 500, and connecting the booster pump component 400 to the water tank component 100, the booster pump component 400 can pressurize the test water flowing into the booster pump component 400 to simulate the water supply pressure of the municipal pipe network. This allows the negative pressure-free test component 500 to operate in a simulated negative pressure-free test environment, and makes the test results of the negative pressure-free water supply equipment 20 more accurate, without causing pressure instability in the actual operation of the negative pressure-free water supply equipment 20.

[0089] By setting up at least one constant pressure test component 300 and at least one negative pressure-free test component 500, with the constant pressure test component 300 connected to the water tank component 100 and the negative pressure-free test component 500 connected to the booster pump component 400, the test system can simultaneously test at least one constant pressure water supply device 10 and at least one negative pressure-free water supply device 20. Compared with the traditional test system that tests sequentially, this parallel testing method significantly improves test efficiency and shortens the overall test time.

[0090] The tank 110 of the water tank assembly 100 is used to store test water. With the automatic water replenishment function of the water replenishment assembly 200, the water level in the tank 110 can be replenished in time when it is lower than the preset level, ensuring a continuous and stable water supply during the test and avoiding interruption of the test due to insufficient water, thereby ensuring the continuity and reliability of the test.

[0091] It should be noted that when the pressure of the test water supplied to the constant pressure test assembly 300 and the booster pump assembly 400 is lower than the preset pressure, the constant pressure test assembly 300 needs to operate at a higher power to simulate constant pressure water supply conditions (simulating water tank supply), and the booster pump assembly 400 also needs to operate at a higher power to simulate municipal water supply conditions. This not only leads to higher operating costs for the constant pressure test assembly 300 and the booster pump assembly 400, but also easily causes malfunctions in these two assemblies. Furthermore, when the test water pressure is lower than the preset pressure, the water pressure supplied to the constant pressure water supply equipment 10 and the negative pressure-free water supply equipment 20 is unstable during the process of the constant pressure test assembly 300 and the booster pump assembly 400 raising the test water pressure to a suitable test pressure, resulting in unstable testing processes and inaccurate test results.

[0092] Therefore, in this embodiment, by providing a water replenishment component 200, the component can replenish water in a timely manner when the test water level in the tank 110 is lower than a preset level, thus providing a controllable water pressure condition to maintain the water pressure of the test water flowing out of the tank 110 within an optimal range. This is particularly important when the testing system simultaneously tests at least one constant pressure water supply device 10 and at least one negative pressure-free water supply device 20, where the consumption of test water is significant. Controllable water pressure conditions ensure the stability of the testing process and the accuracy of the test results.

[0093] It should also be noted that, in order to prevent the test water in the chamber 110 from overflowing, the water replenishment component 200 will stop replenishing the test water when the liquid level of the test water in the chamber 110 reaches the preset level.

[0094] It is understood that the constant pressure water supply equipment 10 and the negative pressure-free water supply equipment 20 mentioned in the embodiments of this application can be used to supply residential water, commercial water and fire-fighting water, etc., and the embodiments of this application do not limit their specific application scenarios.

[0095] The preferred technical solution of the testing system for the secondary water supply equipment according to an embodiment of this application is described below with reference to the accompanying drawings. Figure 2 This is a structural schematic diagram of the water tank assembly; Figure 3 A schematic diagram of the structure of the first support of the constant pressure test assembly; Figure 4 This is a schematic diagram of the booster pump assembly. Figure 5This is a schematic diagram showing the connection between the negative pressure-free test component and the negative pressure-free water supply equipment. Figure 6 This is a front view of the second support of the negative pressure-free test assembly; Figure 7 This is a side view of the second support of the negative pressure-free test assembly; Figure 8 A schematic diagram of the structure of the integrated test component of the test system for the secondary water supply equipment provided in the embodiments of this application.

[0096] In the embodiments of this application, please refer to Figure 1 The housing 110 has a manhole 120. By providing the manhole 120, personnel can enter the housing 110 to maintain the components of the testing system.

[0097] The water tank assembly 100 also includes an overflow pipe 130, which is connected to the tank body 110. When the level of the test water in the tank body 110 reaches the height of the overflow pipe 130, the test water above the overflow pipe 130 can be discharged through the overflow pipe 130 into a test water collection device (not shown). The test water collection device can be a sewage collection device or a water resource recycling device.

[0098] The enclosure 110 is also provided with a vent 140, which allows air to circulate inside and outside the enclosure 110.

[0099] See Figure 2 The water tank assembly 100 also includes a ladder 150, which is mounted on the tank body 110 and can be used for on-site maintenance.

[0100] In some embodiments, see Figure 1 and Figure 2 The water supply component 200 includes: a water supply component (not shown) and a water supply pipe 210, the water supply pipe 210 connecting the water supply component and the housing 110, the water supply component supplying test water to the housing 110 via the water supply pipe 210; a first water supply valve (not shown), connected to the water supply pipe 210, the first water supply valve opening or closing correspondingly to conduct or cut off the test water supplied by the water supply component; and a valve controller 220, connected to the first water supply valve, the valve controller 220 controlling the valve to open or close correspondingly when the test water level in the housing 110 is lower than or reaches a preset level.

[0101] By setting up a water supply component and a water replenishment pipe 210, the water replenishment pipe 210 connects the water supply component to the tank 110, and the water supply component can continuously supply test water to the tank 110.

[0102] By setting a first water supply valve connected to the water supply pipe 210, the first water supply valve can open or close to connect or disconnect the test water supplied by the corresponding water supply component, allowing the testing system to flexibly adjust the water inflow according to actual needs. When water replenishment is needed, opening the first water supply valve can quickly replenish the water volume; when the water volume is sufficient, closing the first water supply valve can prevent test water from overflowing from the tank 110, avoiding unnecessary water waste.

[0103] By configuring a valve controller 220, which is connected to the first water supply valve, the valve controller 220 controls the opening or closing of the first water supply valve when the test water level in the tank 110 is lower than or reaches a preset level, thus achieving automatic level adjustment. Specifically, when the test water level is lower than the preset level, the valve controller 220 automatically opens the first water supply valve to supply water; when the test water level reaches the preset level, the valve controller 220 automatically closes the first water supply valve to stop supplying water. This automated operation reduces the need for manual intervention and improves the system's operating efficiency.

[0104] In some specific embodiments, the valve controller 220 is a float switch, which includes a piston (not shown), a connecting rod (not shown), and a float (not shown). The piston is connected to the first water supply valve, and the connecting rod connects the piston and the float.

[0105] When the test water level in tank 110 is lower than the preset level, the float is in a low position. The float pulls down the piston via the connecting rod, opening the piston. Test water from the water supply unit can then enter tank 110 through the first water supply valve. As test water flows into tank 110, the water level gradually rises. Due to its buoyancy, the float rises with the increasing water level. During this ascent, the float pushes the piston upward via the connecting rod, gradually reducing the opening of the first water supply valve and thus decreasing the flow rate of the test water. When the test water level in tank 110 reaches the preset level, the float rises completely. The rising float pushes the piston to its limit position via the connecting rod, causing the piston to completely close the first water supply valve, thus stopping the test water flow.

[0106] In this embodiment, the float switch and the first water supply valve together form a float control valve. The float of the float control valve is in direct contact with the water surface, enabling it to sense changes in liquid level in real time with a fast response speed. Furthermore, the float control valve has a simple mechanical structure and low maintenance costs, which can reduce the manufacturing and operating costs of the entire testing system.

[0107] In some other specific embodiments, the first water supply valve is an electrically controlled valve, and the valve controller 220 is an electronic level sensor. The electronic level sensor integrates control functions and is communicatively connected to the electrically controlled valve. When the electronic level sensor detects that the level of the test water in the tank 110 is lower than the preset level, the electronic level sensor sends an opening command to the electrically controlled valve to open the valve. When the electronic level sensor detects that the level of the test water in the tank 110 reaches the preset level, the electronic level sensor sends a closing command to the electrically controlled valve to close the valve.

[0108] In this embodiment, the electronic liquid level sensor has high accuracy and flexibility, enabling more precise liquid level control.

[0109] Further, please see Figure 2 The water replenishment assembly 200 also includes a level gauge 230, which is disposed inside the tank 110 and can be used to display the level of the test water inside the tank 110. In some examples, the level gauge 230 is a magnetic float level gauge.

[0110] Currently, during peak water usage periods, multiple secondary water supply devices simultaneously receiving water from the municipal pipeline network can lead to water shortages.

[0111] To address the aforementioned technical issues, please refer to the embodiments of this application. Figure 1 and Figure 8 The testing system for the secondary water supply equipment also includes a controller 640.

[0112] The water supply component 200 also includes a second water supply valve (not shown), which is connected to the water supply pipe 210. The first water supply valve is located between the second water supply valve and the housing 110. The second water supply valve opens or closes to connect or disconnect the test water supplied by the water supply component.

[0113] The constant pressure test assembly 300 includes a first water inlet pipe 310 and a first main control valve 301. The first water inlet pipe 310 is used to connect the housing 110 to each constant pressure water supply device 10. The first main control valve 301 is connected to the first water inlet pipe 310. The first main control valve 301 opens or closes to connect or shut off the first water inlet pipe 310.

[0114] The negative pressure-free test assembly 500 includes a second water inlet pipe 520 and a second main control valve 501. The second water inlet pipe 520 is used to connect the booster pump assembly 400 to each negative pressure-free water supply device 20. The second main control valve 501 is connected to the second water inlet pipe 520. The second main control valve 501 opens or closes to correspondingly conduct or cut off the second water inlet pipe 520.

[0115] The controller 640 is communicatively connected to the second water supply valve, the first main control valve 301, the second main control valve 501, and the booster pump assembly 400. The controller 640 is used to control the first main control valve 301 to open and control the second water supply valve, the second main control valve 501, and the booster pump assembly 400 to close within a first preset time period. The controller 640 is also used to control the second water supply valve, the second main control valve 501, and the booster pump assembly 400 to open and control the first main control valve 301 to close within a second preset time period.

[0116] The first preset time period is the off-peak water usage period, such as 00:00~7:00, 10:00~11:00, 13:00~19:00, and 21:00~00:00; the second preset time period is the peak water usage period, such as 7:00~9:00, 11:00~13:00, and 19:00~21:00.

[0117] By setting up a second water supply valve, a first main control valve 301, a second main control valve 501, and a controller 640, the controller 640 is communicatively connected to the second water supply valve, the first main control valve 301, and the second main control valve 501. During simulated peak water usage periods, the controller 640 can control the second main control valve 501, which is directly connected to the second water inlet pipe 520 (which can be considered as the municipal water network under the pressure boosting of the booster pump assembly 400), and the booster pump assembly 400 to close, thus simulating the situation where the negative pressure water supply equipment 20 is cut off from the municipal water network. Since the water in the tank 110 comes from the municipal water network, in order to avoid water shortage caused by water replenishment to the tank 110, it is also necessary to control the second water supply valve to close in this situation. At the same time, the first main control valve 301, which is directly connected to the first water inlet pipe 310, is opened, and the first water inlet pipe 310 is open, thus simulating the situation where the water storage tank used on site supplies water to the constant pressure water supply equipment 10. Therefore, the testing system for the secondary water supply equipment can simulate a scenario where the negative pressure water supply equipment 20 stops operating while the constant pressure water supply equipment 10 operates normally during peak water usage periods, thus preventing water shortages. It should be noted that the second water supply valve is located upstream of the first water supply valve. The second water supply valve acts as a master water supply control. Even when the constant pressure water supply equipment 10 is supplying water, if there is no test water in the tank 110, the controller 640 can still control the second water supply valve to open, supplying water to the tank 110. In some examples, the second water supply valve is an electrically controlled valve.

[0118] During simulated low water usage periods, controller 640 can close the first main control valve 301, which is directly connected to the first inlet pipe 310, thus cutting off the first inlet pipe 310 and simulating the situation where the water storage tank used on-site stops supplying water to the constant pressure water supply equipment 10. Simultaneously, controller 640 can open the second main control valve 501 and the booster pump assembly 400, which are directly connected to the second inlet pipe 520, thus opening the second inlet pipe 520 and simulating the situation where the municipal water supply network supplies water to the pressureless water supply equipment 20 during low water usage periods. Furthermore, controller 640 can open the second water replenishment valve to replenish water to the tank 110, thus simulating the situation where the water storage tank used on-site is replenished during low water usage periods, so that the water storage tank can supply water to the constant pressure water supply equipment 10 during peak water usage periods.

[0119] The quality of residential water is closely related to residents' health. If the quality of residential water does not meet the requirements, it will have an adverse effect on residents' health.

[0120] To address the aforementioned technical issues, please refer to the following embodiments in some cases: Figure 1 and Figure 8 The testing system for the secondary water supply equipment also includes a controller 640.

[0121] The constant pressure testing assembly 300 includes: a first water inlet pipe 310 connected to a housing 110; at least one first water supply pump group 302, each first water supply pump group 302 being used to connect the first water inlet pipe 310 to each constant pressure water supply device 10, the first water supply pump group 302 being used to pump the test water in the housing 110 to the constant pressure water supply device 10; and a first water quality analyzer 303 connected to the first water inlet pipe 310, the first water quality analyzer 303 being used to detect a first water quality index of the test water in the first water inlet pipe 310, the first water quality index being at least one of a first residual chlorine value, a first turbidity value, a first pH value, and a first temperature value.

[0122] The controller 640 is communicatively connected to the first water quality analyzer 303 and each first water supply pump group 302. The controller 640 is used to control the first water supply pump group 302 to stop operating when the first water quality index does not meet the first preset condition.

[0123] In this embodiment, a first water quality analyzer 303 detects multiple first water quality indicators (first residual chlorine value, first turbidity value, first pH value, and first temperature value), providing a comprehensive data foundation for water quality management. By detecting multiple first water quality indicators, the testing system can more accurately assess the water quality status of the test water. It can not only promptly detect anomalies in a single indicator, but also identify complex water quality problems through comprehensive analysis of multiple indicators, simulating abnormal situations that the constant pressure water supply equipment 10 may encounter during on-site use and proposing corresponding solutions. For example, if the first water quality analyzer 303 detects an abnormal first pH value and an increase in first turbidity, this may indicate a more serious problem with the on-site water tank or first inlet pipe 310, rather than just a simple pH imbalance, requiring investigation of the water tank or first inlet pipe 310. Thus, when the constant pressure water supply equipment 10 encounters such an abnormal situation during on-site use, the on-site water treatment system, water tank, and pipe network can be investigated.

[0124] However, when the first water quality indicator detected by the first water quality analyzer 303 does not meet the first preset condition, that is, when the first water quality indicator does not meet the drinking water standard, the controller 640 controls the first water supply pump group 302 to stop immediately, which can easily generate a water hammer effect, thereby causing damage to the pipelines or equipment of the testing system.

[0125] In response to this, in some embodiments, each first water supply pump group 302 includes multiple first water supply pumps. The first water supply pumps of each first water supply pump group 302 are used to connect the first water inlet pipe 310 to each constant pressure water supply device 10. The first water supply pumps are used to pump test water into the constant pressure water supply device 10.

[0126] The first preset condition includes multiple sub-conditions. When the first water quality index meets the first preset condition, the controller 640 controls the corresponding number of first water supply pumps of the first water supply pump group 302 to stop operating according to the multiple sub-conditions of the first preset condition.

[0127] In this embodiment, the first preset condition is the condition of meeting drinking water standards, and the multiple sub-conditions are different sub-conditions divided according to the degree to which the first water quality index meets the drinking water standards. Depending on the degree to which the first water quality index meets the drinking water standards, each sub-condition controls the number of first water supply pumps in the first water supply pump group 302 to stop operating. Specifically, when the first water quality index is at a good value, the test water will not have any adverse effects, and the controller 640 does not control the first water supply pumps in the first water supply pump group 302 to stop operating; when the first water quality index is at an intermediate value, the controller 640 controls some of the first water supply pumps in the first water supply pump group 302 to stop operating; when the first water quality index is at a poor value (but still meets drinking water standards), the controller 640 only controls one first water supply pump in the first water supply pump group 302 to operate, and all other first water supply pumps in the first water supply pump group 302 stop operating. As can be seen, under the premise that the first water quality indicator meets the drinking water standard, the degree to which the first water quality indicator meets the drinking water standard gradually decreases (from a better value through an intermediate value to a worse value). The number of first water supply pumps in the first water supply pump group 302 controlled by controller 640 also gradually increases. Therefore, when the first water quality indicator changes from a worse value that meets the drinking water standard to any value that does not meet the drinking water standard, the number of operating first water supply pumps changes from one to zero. Compared to the change from multiple operating first water supply pumps to zero, the pressure change in the first inlet pipe 310 is smaller in this embodiment, and water hammer is less likely to occur in the first inlet pipe 310. Therefore, the test system provided in this embodiment can simulate whether the constant pressure water supply equipment 10 has the operating conditions to cope with the water hammer effect.

[0128] Furthermore, as the degree to which the first water quality indicator meets the drinking water standard gradually decreases (from a better value through an intermediate value to a worse value), the number of the first water supply pumps of the first water supply pump group 302 controlled by the controller 640 gradually increases. This can be used to simulate the scenario in which on-site maintenance personnel judge the abnormal situation of the test system and determine the severity of the abnormal situation, thereby taking corresponding measures to solve the problem.

[0129] In other embodiments, the negative pressure-free testing assembly 500 includes: a second water inlet pipe 520 connected to the housing 110; at least one second water supply pump group 502, each second water supply pump group 502 being used to correspondingly connect the second water inlet pipe 520 to each negative pressure-free water supply device 20, the second water supply pump group 502 being used to pump test water into the negative pressure-free water supply device 20; and a second water quality analyzer 503 connected to the second water inlet pipe 520, the second water quality analyzer 503 being used to detect a second water quality index of the test water in the second water inlet pipe 520, the second water quality index including at least one of a second residual chlorine value, a second turbidity value, a second pH value, and a second temperature value.

[0130] The controller 640 is connected to the second water quality analyzer 503 and each second water supply pump group 502. The controller 640 is used to control the second water supply pump group 502 to stop operating when the second water quality index meets the second preset condition.

[0131] The principle and beneficial effects of the negative pressure-free testing component 500 in this embodiment correspond to the principle and beneficial effects of the aforementioned constant pressure testing component 300, and will not be repeated here.

[0132] Furthermore, each second water supply pump group 502 includes multiple second water supply pumps. The second water supply pumps of each second water supply pump group 502 are used to connect the second water inlet pipe 520 to each negative pressure-free water supply device 20. The second water supply pumps are used to pump test water into the negative pressure-free water supply device 20.

[0133] The second preset condition includes multiple sub-conditions. When the second water quality index meets the second preset condition, the controller 640 controls the corresponding number of second water supply pumps of the second water supply pump group 502 to stop operating according to the multiple sub-conditions of the second preset condition.

[0134] The principle and beneficial effects of the negative pressure-free testing component 500 in this embodiment correspond to the principle and beneficial effects of the aforementioned constant pressure testing component 300, and will not be repeated here.

[0135] In some other embodiments, please refer to Figure 1 The constant pressure test assembly 300 includes: a first water inlet pipe 310, which is connected to the housing 110, and has at least one first water inlet interface group 320, which includes multiple first water inlet interfaces of different diameters, and the first water inlet interfaces are used to connect to the first water inlet test pipe 11 of the constant pressure water supply equipment 10; and a first return water pipe 330, which is connected to the housing 110, and has at least one first return water interface group 340, which includes multiple first return water interfaces of different diameters, and the first return water interfaces are used to connect to the first return water test pipe 12 of the constant pressure water supply equipment 10.

[0136] By setting a first water inlet pipe 310, which is connected to the housing 110, the test water in the housing 110 can flow into the first water inlet pipe 310. By setting at least one first water inlet interface group 320 on the first water inlet pipe 310, at least one first water inlet interface group 320 can be used to connect the first water inlet test pipe 11 of at least one constant pressure water supply device 10. When the number of first water inlet interface groups 320 is two or more, the test system can connect multiple constant pressure water supply devices 10 for testing at the same time, which can improve the testing efficiency of the test system and shorten the overall testing time of the test system.

[0137] The first water inlet interface group 320 includes multiple first water inlet interfaces of different diameters. The first water inlet interface group 320 can be adapted to constant pressure water supply equipment 10 of different specifications, which enhances the versatility and adaptability of the test system, so that one test system can meet the test requirements of various models of constant pressure water supply equipment 10.

[0138] For example, each first water inlet port is used to connect to a DN50, DN100, DN150 and DN200 first water inlet test pipe respectively; each first water return port is used to connect to a DN50, DN100, DN150 and DN200 first water return test pipe respectively.

[0139] The installation of the first return water pipe 330 forms a complete water circulation system, realizing the reuse of test water. This not only saves water resources but also ensures the stability of water volume during long-term testing, improving the continuity and environmental friendliness of the test.

[0140] In some examples, the number of first water inlet interface groups 320 is 1, 2 or 3, and correspondingly, the test system can test 1, 2 or 3 constant pressure water supply devices 10.

[0141] It should be noted that both the first water inlet and the first water return can be quick-connect fittings, which can shorten the assembly time of the constant pressure water supply equipment 10, thereby shortening the testing time of the entire testing system and improving testing efficiency.

[0142] It should also be noted that the first inlet pipe 310 is equipped with multiple wafer-type butterfly valves (not shown), each wafer-type butterfly valve being installed on one side of each first inlet port. The wafer-type butterfly valves are used to control the opening and closing of the first inlet ports. The first return pipe 330 is equipped with multiple wafer-type check valves, each wafer-type check valve being installed on one side of each first return port. The wafer-type check valves are used to prevent backflow of test water.

[0143] Further, please see Figure 3 The constant pressure test assembly 300 also includes a plurality of first brackets 350, which are used to be mounted on the first mounting surface and to support at least one of the first inlet pipe 310 and the first return pipe 330.

[0144] By setting up multiple first supports 350, which support at least one of the first inlet pipe 310 and the first return pipe 330, the multiple first supports 350 can provide a more uniform and stable supporting force. Specifically, the multi-point support structure distributes the weight of the first inlet pipe 310 and / or the first return pipe 330, reduces the single-point load pressure, and can improve the structural stability of the entire testing system.

[0145] It should be noted that the first mounting surface can be the ground or other supporting surfaces. This application embodiment does not specifically limit it and can be adjusted according to specific needs.

[0146] In some specific embodiments, the first bracket 350 includes a first vertical support 351 and a second vertical support 352, with the height of the first vertical support 351 being higher than the height of the second vertical support 352; the first bracket 350 also includes a first horizontal support 353 and a second horizontal support 354, with the first horizontal support 353 connected between the first vertical support 351 and the second vertical support 352, and the second horizontal support 354 connected to the first vertical support 351; the first bracket 350 also includes a first clamp 355 and a second clamp 356, with the first clamp 355 securing the first water inlet pipe 310 to the first horizontal support 353, and the second clamp 356 securing the first water return pipe 330 to the second horizontal support 354, thereby achieving the fixation of the first water inlet pipe 310 and the first water return pipe 330.

[0147] Furthermore, please see Figure 1 The constant pressure test assembly 300 also includes at least one first platform base 370, each first platform base 370 is used to place each constant pressure water supply device 10, and the first platform base 370 is used to be set on one side of the drain cover 30. After the test is completed, the test water remaining in the first inlet test pipe 11 and the first return test pipe 12 of the constant pressure water supply device 10 can be discharged into the test water collection device through the gap in the drain cover 30.

[0148] In other embodiments, please refer to Figure 1 and Figure 4 The booster pump assembly 400 includes: a booster inlet pipe 410 and an inlet butterfly valve 420. The booster inlet pipe 410 is connected to the housing 110 via the inlet butterfly valve 420, which controls the opening and closing of the booster inlet pipe 410; at least two booster branch pipes 430 and at least two booster pumps 440. The booster branch pipes 430 are connected to the booster inlet pipe 410, and each booster pump 440 is correspondingly connected to each booster branch pipe 430; and a booster outlet pipe 450. Each booster branch pipe 430 is connected to the booster outlet pipe 450, and the booster outlet pipe 450 is connected to the second inlet pipe 520. The test water, after being boosted by the booster pumps 440, flows sequentially through the booster branch pipes 430 and the booster outlet pipe 450 into the second inlet pipe 520 for testing the negative pressure-free water supply equipment 20.

[0149] Furthermore, the booster pump assembly 400 also includes at least two check valves 460 and at least two outlet butterfly valves 470. Each check valve 460 is correspondingly installed on each booster branch pipe 430, and the check valve 460 is located on the side of the booster pump 440 near the booster inlet pipe 410. The check valve 460 is used to prevent backflow, thereby avoiding cavitation. Each outlet butterfly valve 470 is correspondingly installed on each booster branch pipe 430, and the outlet butterfly valve 470 is located on the side of the booster pump 440 near the booster outlet pipe 450. By closing the outlet butterfly valve 470, the vulnerable parts of the booster pump assembly 400 can be maintained or replaced.

[0150] Furthermore, please see Figure 1 and Figure 4 The testing system for the secondary water supply equipment also includes a pressure sensor 610, which is installed on the booster outlet pipe 450. The pressure sensor 610 is used to detect the pressure of the test water in the booster outlet pipe 450. When the pressure of the test water in the booster outlet pipe 450 is lower than the preset pressure of the water in the municipal pipe network, the testing system can turn on the booster pump 440 to replenish the pressure and meet the pressure of the simulated water in the municipal pipe network.

[0151] In some embodiments, see Figure 1 and Figure 5 The negative pressure-free test assembly 500 includes: a second inlet pipe 520, which is connected to the booster pump assembly 400, and has at least one second inlet interface group 530, which includes multiple second inlet interfaces of different diameters, for connecting to the second inlet test pipe 21 of the negative pressure-free water supply device 20; and a second return pipe 540, which is connected to the housing 110, and has at least one second return interface group 550, which includes multiple second return interfaces of different diameters, for connecting to the second return test pipe 22 of the negative pressure-free water supply device 20.

[0152] By setting a second water inlet pipe 520, which is connected to a booster pump assembly 400, the test water pressurized by the booster pump assembly 400 can flow into the second water inlet pipe 520. By setting at least one second water inlet interface group 530 on the second water inlet pipe 520, at least one second water inlet interface group 530 can be used to connect to the second water inlet test pipe 21 of at least one negative pressure water supply device 20. When the number of second water inlet interface groups 530 is two or more, the test system can connect multiple negative pressure water supply devices 20 for testing at the same time, which can improve the testing efficiency of the test system and shorten the overall testing time of the test system.

[0153] The second water inlet interface group 530 includes multiple second water inlet interfaces of different diameters. The second water inlet interface group 530 can be adapted to different specifications of negative pressure water supply equipment 20, which enhances the versatility and adaptability of the test system, so that one test system can meet the test requirements of multiple models of negative pressure water supply equipment 20.

[0154] For example, each second water inlet is used to connect to a DN50, DN100, DN150 and DN200 second water inlet test pipe respectively; each second water return is used to connect to a DN50, DN100, DN150 and DN200 second water return test pipe respectively.

[0155] The installation of the second return water pipe 540 forms a complete water circulation system, realizing the reuse of test water. This not only saves water resources but also ensures the stability of water volume during long-term testing, improving the continuity and environmental friendliness of the test.

[0156] In some examples, the number of second water inlet interface groups 530 is 1, 2 or 3, and correspondingly, the test system can test 1, 2 or 3 negative pressure water supply devices 20.

[0157] It should be noted that both the second water inlet and the second water return can be quick-connect fittings, which can shorten the assembly time of the negative pressure water supply equipment 20, thereby shortening the testing time of the entire testing system and improving testing efficiency.

[0158] It should also be noted that, please refer to Figure 7 and Figure 8 Multiple electric valves 690 are installed on the second inlet pipe 520, each electric valve 690 being positioned on one side of each second inlet interface. The electric valves 690 are used to control the opening and closing of the second inlet interfaces. Multiple wafer-type check valves are installed on the second return pipe 540, each wafer-type check valve being positioned on one side of each second return interface. The wafer-type check valves are used to prevent backflow of test water.

[0159] Further, please see Figure 1 The negative pressure test assembly 500 also includes at least one pressure stabilizing tank 510, each pressure stabilizing tank 510 being used to connect to each negative pressure water supply device 20.

[0160] By equipping each negative pressure water supply device 20 with an independent pressure stabilizing tank 510, water pressure fluctuations can be effectively mitigated, and water supply stability can be maintained, so that each negative pressure water supply device 20 can obtain a stable inlet water pressure, thereby improving the reliability and efficiency of the entire testing system.

[0161] Furthermore, the height of the second water inlet is higher than the height of the pressure stabilizing tank 510.

[0162] While the pressure stabilizing tank 510 alleviates water pressure fluctuations, it also causes a certain pressure loss, which can lead to inaccurate test results.

[0163] In this embodiment, by increasing the height of the second water inlet, the gravitational potential energy of the test water is used to compensate for the pressure loss caused by the pressure stabilizing tank 510, thus ensuring the normal water inlet pressure of the negative pressure-free water supply equipment 20.

[0164] In some embodiments, see Figure 6 and Figure 7 The negative pressure-free testing assembly 500 also includes a second support 560, which includes: a plurality of first vertical beams 561; a plurality of base beams 562, each base beam 562 correspondingly connecting two adjacent first vertical beams 561; a plurality of first horizontal beams 563, each first horizontal beam 563 correspondingly connecting two adjacent first vertical beams 561, the first horizontal beams 563 being located at the top of the first vertical beams 561; and a plurality of support seats, the support seats being disposed on the first horizontal beams 563, the support seats being used to support the second water inlet pipe 520.

[0165] By setting up multiple first vertical beams 561, multiple base beams 562, and multiple first horizontal beams 563, each base beam 562 is connected to two adjacent first vertical beams 561, and each first horizontal beam 563 is connected to two adjacent first vertical beams 561, so that each first vertical beam 561, each base beam 562, and each first horizontal beam 563 together form a stable frame structure with good support effect; by setting up a support base, which is set on the first horizontal beam 563 and the first horizontal beam 563 is located on top of the first vertical beam 561, the support base can support the second water inlet pipe 520 on the top of the first vertical beam 561, so as to realize the high-level placement of the second water inlet pipe 520.

[0166] In specific implementation, the base beam 562 can be located at the bottom of the second vertical beam 565, and the base beam 562 contacts the second mounting surface to achieve the installation of the second bracket 560. Alternatively, the base beam 562 can be located in the middle of the second vertical beam 565, in which case the second vertical beam 565 directly contacts the second mounting surface to achieve the installation of the second bracket 560. It should be noted that the second mounting surface can be the ground or other supporting surfaces; this embodiment does not specifically limit it and can be adjusted according to specific needs.

[0167] Furthermore, the second support 560 also includes multiple reinforcing beams 564, which connect at least two of the first vertical beam 561, the base beam 562, and the first horizontal beam 563, thereby improving the structural strength of the second support 560 and thus enhancing its support performance.

[0168] In other embodiments, please refer to Figure 1The negative pressure-free test assembly 500 also includes at least one second platform base 580, each second platform base 580 is used to place each negative pressure-free water supply device 20, and the second platform base 580 is used to be set on one side of the drain cover 30. After the test is completed, the test water remaining in the second inlet test pipe 21 and the second return test pipe 22 of the negative pressure-free water supply device 20 can be discharged into the test water collection device through the gap in the drain cover 30.

[0169] For some specific implementation methods, please refer to Figure 6 and Figure 7 The support includes: multiple second vertical beams 565 and multiple second horizontal beams 566. The second vertical beams 565 are connected to the first horizontal beam 563. Each second horizontal beam 566 is connected to two adjacent second vertical beams 565, and the second horizontal beam 566 is located at the top of the second vertical beams 565. The second horizontal beam 566 is used to support the second water inlet pipe 520.

[0170] By setting multiple second vertical beams 565 and multiple second horizontal beams 566, the second vertical beams 565 are connected to the first horizontal beam 563, and each second horizontal beam 566 is connected to two adjacent second vertical beams 565, so that each second vertical beam 565 and each second horizontal beam 566 together form a stable frame structure with good support effect; and the second horizontal beam 566 is located on top of the second vertical beams 565, and the second horizontal beam 566 is used to support the second water inlet pipe 520, which can realize the high-level placement of the second water inlet pipe 520.

[0171] In specific implementation, the second water inlet pipe 520 includes an interface branch pipe (not shown) corresponding to the second water inlet interface, and each second crossbeam 566 is used to support the interface branch pipe.

[0172] In some embodiments, see Figure 8 The testing system for the secondary water supply equipment also includes a comprehensive testing component 600, which includes a pressure sensor 610. The pressure sensor 610 is connected to the negative pressure-free testing component 500 and is used to detect the pressure data of the test water flowing out of the booster pump component 400.

[0173] By incorporating a pressure sensor 610 connected to the negative pressure-free testing assembly 500, the pressure sensor 610 detects the pressure data of the test water flowing out of the booster pump assembly 400. This allows the testing system to monitor water pressure in real time, ensuring that the water pressure remains within a suitable range during the test.

[0177] Further, please see Figure 8 The integrated testing component 600 further includes: a controller 640, which is communicatively connected to a pressure sensor 610, each of the first electromagnetic flowmeters 620 and each of the second electromagnetic flowmeters 630, and is used to activate the pressure sensor 610, each of the first electromagnetic flowmeters 620 and each of the second electromagnetic flowmeters 630 when the constant pressure testing component 300 and the negative pressure-free testing component 500 are running; a first switch 650, which is communicatively connected to the controller 640, and is used to transmit pressure data, flow data of each constant pressure water supply device 10 and flow data of each negative pressure-free water supply device 20; and an industrial control computer 660, which is used to acquire pressure data, flow data of each constant pressure water supply device 10 and flow data of each negative pressure-free water supply device 20 to generate a first data report for traceability.

[0178] The controller 640 is communicatively connected to the pressure sensor 610, each of the first electromagnetic flowmeters 620, and each of the second electromagnetic flowmeters 630, and activates these devices when the constant pressure test assembly 300 and the negative pressure-free test assembly 500 are running.

Specifically, the average energy consumption per ton of water for each constant pressure water supply device 10 is obtained based on the flow data of each constant pressure water supply device 10, the head of each first water supply pump, and the power data of each constant pressure water supply device 10. If the average energy consumption per ton of water is greater than 1 kWh / m³ MPa, then the constant pressure water supply device 10 is considered a high-energy-consuming device. The detection principle of the negative pressure-free water supply device 20 is the same as that of the constant pressure water supply device 10, and will not be described again here.
