Description

Technical Field

[0001] The utility model belongs to the field of performance testing of booster pumps and relates to a testing device for the performance of booster pumps. Background Art

[0002] At present, booster pumps are widely used in multiple occasions that require increasing the pressure of gases or liquids, such as domestic water use, workshops, fire protection, sprinkler irrigation, etc. An air inlet and an air outlet are provided on the booster pump. External air sources enter the booster pump from the air inlet, and the pressurized gas exits from the air outlet after pressurization.

[0003] The performance of the booster pump directly affects the actual working effect. However, it is not until it is applied in work and the actual effect is found to be unsatisfactory that it is realized that there are problems with the performance of the booster pump, which will disrupt the construction rhythm and seriously affect the construction efficiency. Therefore, a testing device for detecting the performance of the booster pump is needed.

[0004] For this reason, a Chinese patent application (application number: 202020245794.9) discloses a booster pump testing device, which includes a water delivery pipe. An inlet butterfly valve and a booster pump are sequentially arranged at the water inlet end of the water delivery pipe. A booster pump temperature measuring area and a booster pump current measuring area are arranged on the booster pump; an electromagnetic flowmeter, a pressure gauge and an outlet butterfly valve are sequentially arranged on the water delivery pipe after the outlet of the booster pump.

[0005] However, the above method has the following defects: During work, it is necessary to manually connect the water delivery pipe and the booster pump first, and then open the inlet butterfly valve. Water flows into the booster pump for pressurization. After the test is completed, the inlet butterfly valve is closed, and then the water delivery pipe is manually removed from the booster pump. In this way, the staff repeats the installation and disassembly operations of the water delivery pipe for each booster pump to be tested. The operation of the detection device is relatively troublesome, and the water delivery pipe is frequently bent and stretched during repeated installation and disassembly, which is prone to fatigue cracks and has large wear. Summary of the Utility Model

[0006] The purpose of the present utility model is to address the above problems existing in the prior art and propose a testing device for the performance of a booster pump. The technical problem to be solved by the present utility model is: how to make the detection device have small wear and convenient operation.

[0007] The purpose of the present utility model can be achieved by the following technical solutions: A testing device for the performance of a booster pump includes an air inlet pipe. It is characterized in that the testing device further includes a platform. A sliding mechanism, a limiting block and a mounting seat for placing the booster pump are fixedly arranged on the platform. An air inlet nozzle connected to the air outlet end of the air inlet pipe is arranged on the sliding mechanism. An air outlet nozzle is arranged on the limiting block. The sliding mechanism can drive the air inlet nozzle to approach the mounting seat so that the air inlet nozzle and the air outlet nozzle clamp and fix the booster pump.

[0008] An air inlet and an air outlet are respectively arranged on both sides of the booster pump. The external air source enters the booster pump to be tested through the air inlet pipe, the air inlet nozzle and the air inlet in sequence. Specifically, before the external air source enters the air inlet pipe, it will first pass through the solenoid valve, the throttle valve and the air storage tank in sequence. In actual work, first align the air outlet with the air outlet nozzle, then place the booster pump on the mounting seat and connect the air outlet to the air outlet nozzle to complete the preliminary positioning of the booster pump. Then, the sliding mechanism drives the air inlet nozzle to approach the booster pump so that the air inlet nozzle is connected to the air inlet. At this time, the air inlet nozzle and the air outlet nozzle clamp the booster pump and stably fix the booster pump on the mounting seat. A test port communicating with the air outlet nozzle is also arranged on the limit table, and an air flow meter is arranged at the test port to judge whether the measured air flow rate is within the preset range. If it is within the preset range, the performance of the booster pump is qualified; otherwise, it is unqualified. There is no need to additionally set and control other parts to fix the booster pump. When the air inlet nozzle is connected to the air inlet and the air outlet nozzle is connected to the air outlet, the air inlet nozzle and the air outlet nozzle apply equal and opposite acting forces to the booster pump to be tested, clamp and fix the booster pump on the mounting table, making the detection device work stably, with a simple structure and convenient operation. The air inlet pipe is fixedly connected to the air inlet nozzle, and there is no need for manual repeated bending and plugging of the air inlet pipe. The air inlet nozzle approaches or moves away from the booster pump on a preset track to connect or disconnect the air inlet nozzle from the air inlet, avoiding wear caused by part collision during manual alignment, making the detection device have less wear and convenient operation. Using gas to detect the performance of the booster pump, compared with using water liquid for detection, it avoids corrosion caused by the contact between water liquid and the test device, and the test device has less wear.

[0009] For the above test device for the performance of the booster pump, a mounting groove is formed by the depression of the upper surface of the mounting seat, and the mounting groove penetrates through the side wall of the mounting seat along the length direction. It is preset that the air outlet nozzle and the air outlet are at the same height, and the mounting groove penetrates through the side wall of the mounting seat along the length direction. When the booster pump to be tested is placed on the mounting seat, the side of the booster pump provided with the air outlet can protrude from the side wall of the mounting seat, align the air outlet with the air outlet nozzle, and connect the air outlet to the air outlet nozzle. The side of the booster pump protruding from the mounting seat can also abut against the limit block, that is, the limit block and the mounting seat jointly play a limiting role, making full use of existing parts and without additionally adding a limiting structure, making the detection device have a simple structure and convenient operation.

[0010] The above-mentioned test device for the performance of the booster pump, the air inlet nozzle can extend into the installation groove along the length direction of the installation groove. It is preset that the air inlet nozzle and the air inlet are at the same height. Align the air inlet nozzle along the length direction of the installation groove close to the air inlet, and connect the air inlet nozzle and the air inlet. At the same time, the air inlet nozzle and the air outlet nozzle clamp and fix the booster pump. The installation groove guides the movement of the air inlet nozzle, enabling the air inlet nozzle to smoothly extend into the installation groove along the length direction of the installation groove and connect with the air inlet, avoiding wear caused by the shaking and bumping of the air inlet nozzle, with less wear on the test device, and also making the detection device work stably and operate conveniently. At this time, both the air inlet nozzle and the air inlet are located in the installation groove, and the installation groove limits the cooperation between the air inlet and the air inlet nozzle, making the detection device work stably and operate conveniently.

[0011] The above-mentioned test device for the performance of the booster pump, a limiting groove communicating with the installation groove is further recessed on the upper surface of the installation base, and the width of the limiting groove is larger than the width of the installation groove. When the booster pump is placed on the installation base, align the booster pump with the position of the limiting groove and place it on the limiting groove. Relatively speaking, the air inlet and air outlet of the booster pump are smaller than the booster pump body. The combination of the installation groove and the limiting groove enables the installation groove with a smaller groove width to play a better guiding role in the movement of the air inlet nozzle, while the limiting groove with a larger groove width plays a limiting role on the booster pump body. There is no need to additionally set and control other parts to assist the operator in finding the appropriate position to place the booster pump, making the detection device work stably and operate conveniently.

[0012] The above-mentioned test device for the performance of the booster pump, the sliding mechanism includes a sliding cylinder and a sliding plate. The air inlet nozzle is fixedly connected to the sliding plate. A guiding groove is recessed on the upper surface of the sliding cylinder. The sliding plate is slidably connected to the sliding cylinder, and the sliding plate can move back and forth along the length direction of the guiding groove. The sliding plate can move back and forth along the length direction of the guiding groove to connect or disconnect the air inlet nozzle from the air inlet of the booster pump. The guiding groove guides the movement of the sliding plate, avoiding wear caused by the shaking and bumping of the sliding plate, making the detection device work stably and operate conveniently, and also reducing the wear of the detection device.

[0013] Compared with the prior art, the test device for the performance of the present booster pump has the following advantages:

[0014] 1. In the test device for the performance of the present booster pump, there is no need to additionally set and control other parts to fix the booster pump. When the air inlet nozzle is connected to the air inlet and the air outlet nozzle is connected to the air outlet, the air inlet nozzle and the air outlet nozzle exert equal and opposite acting forces on the booster pump to be tested, clamping and fixing the booster pump on the installation table, making the detection device work stably, with a simple structure and convenient operation.

[0015] 2. In the test device for the performance of this booster pump, the intake pipe is fixedly connected to the intake nozzle, eliminating the need for manual repeated bending and plugging / unplugging of the intake pipe. The intake nozzle approaches or moves away from the booster pump along a preset trajectory to connect or disconnect the intake nozzle from the intake port, avoiding wear caused by part collisions during manual alignment, resulting in less wear of the detection device and convenient operation.

[0016] 3. In the test device for the performance of this booster pump, the performance of the booster pump is detected using gas. Compared with using liquid for detection, it avoids corrosion caused by the contact between the liquid and the test device, and the test device has less wear. Description of the Drawings

[0021] The following are specific embodiments of the present invention in combination with the drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0022] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the technical field to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0023] As Figure 1 、 Figure 2 and Figure 3 shown, the test device for the performance of this booster pump includes a throttle valve, a solenoid valve, an air storage tank, and an intake pipe 1. Intake ports and outlet ports are respectively provided on both sides of the booster pump. The external air source sequentially passes through the solenoid valve, the throttle valve, and the air storage tank, and then enters the intake pipe 1. The solenoid valve controls whether gas enters the booster pump. The throttle valve further precisely adjusts the gas flow rate. The air storage tank plays a buffering role for the gas to ensure that when the valve of the booster pump is opened instantaneously, the air pressure inside the booster pump does not fluctuate too much.

[0024] The test device further includes a platform 2, on which a sliding mechanism 3 is fixed. The sliding mechanism 3 includes a sliding cylinder 3a and a sliding plate 3b. A guiding groove 10 is formed by recessing the upper surface of the sliding cylinder 3a. The sliding plate 3b is slidably connected to the sliding cylinder 3a. An air inlet nozzle 6 connected to the outlet end of the air inlet pipe 1 is fixed on the sliding plate 3b, and the sliding plate 3b can approach or move away from the booster pump along the length direction of the guiding groove 10, so that the air inlet nozzle 6 is connected to or disconnected from the air inlet.

[0025] A limiting block 4 and a mounting seat 5 are also fixedly arranged on the platform 2. An air outlet nozzle 7 is arranged on the limiting block 4.

[0026] A test port communicated with the air outlet nozzle 7 is also arranged on the limiting platform, and an air flow meter is arranged at the test port.

[0027] A mounting groove 8 and a limiting groove 9 are formed by recessing the upper surface of the mounting seat 5. The mounting groove 8 penetrates through the side wall of the mounting seat 5 along the length direction. The limiting groove 9 is communicated with the mounting groove 8 and the width of the limiting groove 9 is larger than that of the mounting groove 8. The lower end of the booster pump extends into the limiting groove 9 and abuts against the inner wall of the limiting groove 9. When placing the booster pump on the mounting seat 5, align the booster pump with the position of the limiting groove 9, and then place it on the limiting groove 9. One side of the booster pump provided with an air outlet protrudes from the side wall of the mounting seat 5 and the air outlet is connected to the air outlet nozzle 7. At this time, the sliding plate 3b drives the air inlet nozzle 6 to approach the booster pump along the length direction of the guiding groove 10, and the air inlet nozzle 6 extends into the mounting groove 8 along the length direction of the mounting groove 8 and is connected to the air inlet.

[0028] Relatively speaking, the air inlet and air outlet of the booster pump are smaller than the booster pump body. The arrangement of the mounting groove 8 and the limiting groove 9 enables the mounting groove 8 with a smaller groove width to play a better guiding role in the movement of the air inlet nozzle 6, while the limiting groove 9 with a larger groove width plays a limiting role in the booster pump body. There is no need to additionally set and control other parts to assist the operator to find the appropriate position for placing the booster pump, making the detection device work stably and easy to operate.

[0029] The preset air inlet nozzle 6 and the air inlet port, and the air outlet nozzle 7 and the air outlet port are at the same height. The installation groove 8 runs through the side wall of the mounting base 5 along the length direction. When the booster pump to be tested is placed on the mounting base 5, the side of the booster pump provided with the air outlet can protrude from the side wall of the mounting base 5, align the air outlet with the air outlet nozzle 7, and connect the air outlet with the air outlet nozzle 7. Then, align the air inlet nozzle 6 along the length direction of the installation groove 8 close to the air inlet port, and connect the air inlet nozzle 6 and the air inlet port. At the same time, the air inlet nozzle 6 and the air outlet nozzle 7 clamp and fix the booster pump. The installation groove 8 plays a guiding role, avoiding collisions and wear when aligning the air inlet nozzle 6 with the air inlet port and the air outlet nozzle 7 with the air outlet port, and also facilitating the installation and disassembly operations. Even if the test device has little wear, it also makes the detection device work stably and the operation convenient. When the air outlet is connected to the air outlet nozzle 7, the side of the booster pump provided with the air outlet protrudes from the side wall of the mounting base 5 and abuts against the limiting block 4. The limiting block 4, the limiting groove 9 and the installation groove 8 jointly play a limiting role on the booster pump, which is beneficial to quickly and conveniently position and install the booster pump. At the same time, the guiding groove 10 plays a guiding role in the movement of the air inlet nozzle 6, which is beneficial to accurately connect the air outlet with the air outlet nozzle 7. At this time, both the air outlet and the air outlet nozzle 7 are within the installation groove 8, and the installation groove 8 plays a limiting role in the cooperation between the air outlet and the air outlet nozzle 7, which is beneficial to the booster pump to operate stably, avoiding mechanical component wear caused by vibration, noise or overload, making the detection device work stably and the operation convenient, and also making the detection device have little wear.

[0030] In actual work, first align the air outlet with the air outlet nozzle 7, then place the booster pump on the mounting base 5 and connect the air outlet with the air outlet nozzle 7 to complete the preliminary limiting of the booster pump. Then, the sliding plate 3b approaches the mounting base 5 along the length direction of the guiding groove 10, and the air inlet nozzle 6 approaches the booster pump to connect the air inlet nozzle 6 with the air inlet port. At this time, the air inlet nozzle 6 and the air outlet nozzle 7 clamp the booster pump, and the booster pump is stably fixed on the mounting base 5, and an air flowmeter is used to judge the performance of the booster pump.

[0031] Specifically, first stably fix the booster pump to be tested on the mounting base 5, then open the solenoid valve and the throttle valve, and flush gas into the test chamber of the booster pump. The air flowmeter starts to work. After a certain amount of gas is flushed in, a pressure difference is formed between the air outlet and the air inlet port, and the internal valve of the product is opened. At the moment of opening, the PLC (programmable logic controller) detects the current. The moment the current is detected, the flowmeter stops working and records the air flow measured during this period into the PLC, and judges whether the air flow is within the preset range. If it is within the preset range, it is qualified; otherwise, it is unqualified.

[0032] In the test device for the performance of this booster pump, there is no need to separately set up and control other parts to fix the booster pump. When the air inlet nozzle 6 is connected to the air inlet and the air outlet nozzle 7 is connected to the air outlet, the air inlet nozzle 6 and the air outlet nozzle 7 apply equal and opposite acting forces to the booster pump to be tested, clamping and fixing the booster pump on the installation table, making the detection device work stably, with a simple structure and convenient operation. The air inlet pipe 1 is fixedly connected to the air inlet nozzle 6, eliminating the need for manual repeated bending and plugging of the air inlet pipe 1. The air inlet nozzle 6 approaches or moves away from the booster pump on a preset trajectory to connect or disconnect the air inlet nozzle 6 from the air inlet, avoiding wear caused by part collision during manual alignment, resulting in less wear of the detection device and convenient operation. Using gas to detect the performance of the booster pump, compared with using water liquid for detection, corrosion caused by the contact between water liquid and the test device is avoided, and the test device has less wear.

[0033] Although terms such as the air inlet pipe 1, platform 2, sliding mechanism 3, sliding cylinder 3a, sliding plate 3b, limit block 4, mounting seat 5, air inlet nozzle 6, air outlet nozzle 7, mounting groove 8, limit groove 9, guide groove 10, etc. are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
