Description

Technical Field

[0001] The present invention relates to the technical field of cooling water pump testing tools, in particular to a cooling water pump testing system and method. Background Art

[0002] Cooling water pumps are suitable for conveying clean water or liquids with physical and chemical properties in high-pressure operating systems, such as water supply for high-rise buildings, boiler feed water, HVAC refrigeration cycles, hot and cold water circulation pressurization and equipment supporting bathrooms, fire protection systems, etc., for conveying or pipeline pressurization. Before leaving the factory, the cooling water pump usually needs to use a test system to test its parameters such as head.

[0003] However, the existing test system has great defects during use. Factors such as the smoothness of the inner wall of the pipe in the existing test system will cause certain errors in the test system. Without knowing the amount of system test error, the cooling water pump is directly tested and the real usage data of the cooling water pump cannot be obtained. At the same time, there are no standard cooling water pump operating parameters in the system as a reference, which makes the data of the cooling water pump tested by the test system not intuitive enough. The existing test system is troublesome to replace the test water and is not convenient to use. The existing test system recycles the test water. The test water and the reflux test water have a large potential energy, which will cause serious interference to the cooling water pump test data, resulting in the system's cooling water pump test being not accurate enough.

[0006] Preferably, the delivery assembly includes a support frame, a conveyor chain and a limit frame. Support legs are welded on both sides of the bottom of the support frame, and the support legs are installed on the top of the support plate. Each side of the support frame is rotatably equipped with two gears. The two conveyor chains are equipped with gear transmission on both sides of the support frame. A driving motor for driving the gear to rotate is horizontally installed on the side of one end of the support frame. Several limit frames are arranged on the two conveyor chains. A carrier plate is padded in the limit frame. By using the driving motor to drive the carrier plate and the limit frame, the cooling water pump is sent to the test area by moving the carrier plate and the limit frame. No manual lifting is required, which saves manpower. Moreover, by transmitting through the conveyor chain, the test of multiple cooling water pumps can be completed more quickly.

[0007] Preferably, a lifting assembly is installed at the bottom of the delivery assembly just below the end of the test drain pipe, and fixing assemblies are installed at both sides of the top of the delivery assembly at the lifting assembly.

[0008] Preferably, the jacking assembly includes a mounting frame, a first hydraulic cylinder and a top plate.

A second hydraulic rod is provided at one end of the second hydraulic cylinder. The clamping plate is fixed on the end of the second hydraulic rod away from the second hydraulic cylinder. The second hydraulic rod is driven to move by the second hydraulic cylinder, and the second hydraulic rod drives the clamping plate to clamp the cooling water pump, so that the operation of the cooling water pump is more stable. The cooling water pump is fixed by driving the second hydraulic cylinder, and the speed of fixing and removing the cooling water pump is faster, making the use efficiency of the system higher.

[0010] Preferably, an auxiliary water inlet valve is installed on the auxiliary water inlet pipe, an auxiliary drain valve is installed on the auxiliary drain pipe, and a water change valve is installed on one end of the monitoring pipe close to the auxiliary drain pipe. The auxiliary water inlet valve, auxiliary drain valve, test drain valve and water lock valve are all opened, and then the water change valve is closed. The clean water in the water tank and the water tank can be discharged through the auxiliary water pump, which makes it convenient to replace the water in the water tank and the water tank.

[0011] Preferably, a test drain valve and a water lock valve are provided on the test drain pipe. The test drain valve is located at one end of the test drain pipe close to the auxiliary water pump, and the water lock valve is located at the end of the test drain pipe away from the auxiliary water pump. By setting the water lock valve, after the cooling water pump test is completed, the water lock valve is closed to prevent the clean water in the pipe from flowing out. On the one hand, it avoids getting the outside of the system and the cooling water pump wet, reducing the cleaning work after the system test. On the other hand, it reduces the waste of clean water used for testing and saves the use cost of the system.

[0012] Preferably, the first-level water stabilizing plate and the second-level water stabilizing plate are both provided with a number of water-permeable holes, and the middle parts of the first-level water stabilizing plate and the second-level water stabilizing plate are both provided with a number of water-passing channels, several second-level water stabilizing plates are vertically fixed in the middle of the water tank, several first-level water stabilizing plates are horizontally fixed inside one end of the water tank, and the first-level water stabilizing plate is located below the first water inlet and the second water inlet, and the channel in the middle of the first-level water stabilizing plate is located between the first water inlet and the second water inlet. By arranging the second-level water stabilizing plate in the water tank, a blocking effect is played on the water, the flow rate of the water is reduced, and the water flow returning to the pumping chamber is smoother, thereby reducing the interference of the potential energy of the water flow on the cooling water pump test. By arranging the first drain and the second drain in the drainage chamber, the water flows through the first drain and the second drain converge on the first-level water stabilizing plate and collide with each other, which can effectively weaken the potential energy of the water flow, and under the obstruction of the first-level water stabilizing plate, the potential energy of the water flow is further weakened, thereby further reducing the interference of the potential energy of the water flow on the cooling water pump test.

A flooding plate is fixed in the drainage chamber of the water tank, and the flooding plate is located between the first drain port and the second drain port. The bottom of the flooding plate is fixed to the inclined plate, and a notch is provided on the top of the flooding plate. By setting the filter frame, the water used for the test can be filtered to avoid the appearance of impurities such as rust in the test water after long-term use, thereby avoiding the impurities in the water from damaging the test cooling water pump. At the same time, it also avoids the impurities in the water from affecting the accuracy of the test data of the test system. By setting the flooding plate, the test water in the drainage chamber that is higher than the notch above the flooding plate flows over the flooding plate, and is used in conjunction with the inclined plate to balance the water flow of the first drain port and the second drain port, thereby improving the effect of the water flow below the first drain port and the second drain port colliding with each other to weaken the potential energy.

[0014] Preferably, the method of use specifically comprises the following steps:

[0015] Step 1: Fill the water tank with clean water and inject about one-third of clean water into the water tank, close the test drain valve, open the auxiliary water inlet valve, auxiliary drain valve and water exchange valve, turn on the switch of the auxiliary water pump, and the auxiliary water pump pumps water through the auxiliary water inlet pipe and sends the clean water into the monitoring pipe through the auxiliary drain pipe. Monitor the flow data of the auxiliary water pump through the flow sensor on the monitoring pipe, and monitor the water pressure data of the water outlet of the auxiliary water pump through the water pressure sensor on the monitoring pipe. After recording multiple sets of relevant data of the auxiliary water pump, turn off the auxiliary water pump, close the auxiliary water inlet valve and auxiliary drain valve;

[0016] Step 2: Place the cooling water pump to be tested in a limit frame at the end of the delivery assembly, support the cooling water pump through the carrier plate, drive the gear to rotate through the drive motor, and transmit the transmission chain through the rotating gear. The transmission chain drives the cooling water pump to move through the limit frame and the carrier plate, and moves the cooling water pump to the top of the jacking assembly. Driven by the first hydraulic cylinder, the first hydraulic rod moves, and the first hydraulic rod drives the top plate to move up and down, and moves the top plate upward.

After fixing the cooling water pump, the water inlet end of the cooling water pump is connected to the test water inlet pipe, and the water outlet end of the cooling water pump is connected to the test drain pipe;

[0017] Step 3: After connecting the cooling water pump to the system, open the water lock valve and the test drain valve, turn on the cooling water pump, and the cooling water pump will pump clean water out of the pumping chamber of the water tank through the test water inlet pipe, and send the clean water into the monitoring pipe through the test drain pipe. The flow sensor on the monitoring pipe is used to monitor the flow of the cooling water pump, and the water pressure sensor installed on the test water inlet pipe is used to monitor the water inlet pressure of the cooling water pump. The water pressure sensor installed on the monitoring pipe is used to monitor the water outlet pressure of the cooling water pump. The data of the auxiliary water pump monitored previously is used as a reference, and analysis and calculation are performed based on the changes in the monitored cooling water pump data to obtain the actual head and flow of the cooling water pump, and complete the test of the cooling water pump.

On the other hand, the auxiliary water pump pre-tests multiple groups of data. The auxiliary water pump is used as a standard water pump. The tested data can be used as reference data for the cooling water pump test data, which can more intuitively reflect the shortcomings of the cooling water pump, thereby making the test system more intuitive for cooling water pump testing. On the other hand, the auxiliary water inlet valve, auxiliary drain valve, test drain valve and water lock valve are all opened, and then the water change valve is closed. The clean water in the water tank and the water tank can be discharged through the auxiliary water pump, thereby facilitating the replacement of water in the water tank and the water tank, thereby improving the convenience of replacing clean water and cleaning the test system.

On the other hand, a lifting component is provided at the bottom of the delivery component, and the cooling water pump on the carrier plate is driven by a first hydraulic cylinder to lift up the cooling water pump, so that the cooling water pump can reach the test area more accurately. By providing a water lock valve, after the cooling water pump test is completed, the water lock valve is closed to prevent the clean water in the pipeline from flowing out. On the one hand, it avoids wetting the outside of the system and the cooling water pump, reduces the cleaning work after the system test, thereby further improving the convenience of the system. On the other hand, it reduces the waste of clean water for testing, saving the use cost of the system.

[0021] (3) In the present invention, when the system tests the cooling water pump, the cooling water pump pumps out the water in the pumping chamber through the test water inlet pipe, and sends the water to the transfer chamber through the test drain pipe and the monitoring pipe. The water in the transfer chamber enters the drain chamber through the opening at the bottom of the baffle, and the water in the drain chamber enters the water tank through the first drain port and the second drain port. The water in the water tank enters the pumping chamber through the water gushing pipe port. During the testing process of the cooling water pump, the test water is recycled. In this way, on the one hand, the test system only needs a small amount of clean water to be tested, and a large amount of water will not be wasted, thereby making the use of the test system more environmentally friendly. On the other hand, the test system is smaller in size and occupies less space, which is convenient for use in various venues.

Under the obstruction of the primary water stabilizing plate 104, the potential energy of the water flow is further weakened, thereby further reducing the interference of the potential energy of the water flow on the cooling water pump test, thereby further improving the accuracy of the use of the system.

[0039] In an optional implementation of this embodiment, the pumping chamber 201 is located at one end of the water tank 2, the transfer chamber 202 is located in the middle section of the water tank 2, the transfer chamber 202 is connected to the drainage chamber 203, and an inclined plate 204 is provided at the bottom of the transfer chamber 202 and the drainage chamber 203. A baffle 208 is fixed between the transfer chamber 202 and the drainage chamber 203 in the water tank 2, and a passage for water to pass through is left between the baffle 208 and the inclined plate 204 in the water tank 2, and a filter frame 209 with filter holes is fixed on the bottom of the baffle 208. The top of the filter frame 209 is provided with an opening, and the bottom of the filter frame 209 is fixed to the inclined plate 204. A flooding plate 210 is fixed in the drainage chamber 203 in the water tank 2. The flooding plate 210 is located between the first drain port 206 and the second drain port 207. The bottom of the flooding plate 210 is fixed to the inclined plate 204, and a notch is provided on the top of the flooding plate 210. By providing the filter frame 209, the water used for the test can be filtered to prevent the test water from being used for a long time and containing impurities such as rust, thereby preventing the impurities in the water from damaging the cooling water pump of the test. This makes the use of the test system more reliable, and at the same time, it prevents impurities in the water from affecting the accuracy of the test data of the test system, thereby further improving the accuracy of the use of the test system. By setting the overflow plate 210, the test water in the drainage chamber 203 that is higher than the gap above the overflow plate 210 flows over the overflow plate 210, and is used in conjunction with the inclined plate 204 to balance the water flow of the first drain port 206 and the second drain port 207, thereby improving the effect of the water flow below the first drain port 206 and the second drain port 207 colliding with each other to weaken the potential energy.

[0040] When in use, first, fill the water tank 1 with clean water, and inject about one-third of clean water into the water tank 2, close the test drain valve 501, open the auxiliary water inlet valve 302, the auxiliary drain valve 304 and the water change valve 603, turn on the switch of the auxiliary water pump 3, and the auxiliary water pump 3 pumps water through the auxiliary water inlet pipe 301, and sends the clean water into the monitoring pipe 6 through the auxiliary drain pipe 303. The flow data of the auxiliary water pump 3 is monitored by the flow sensor 601 on the monitoring pipe 6, and the water pressure data of the water outlet of the auxiliary water pump 3 is monitored by the water pressure sensor 602 on the monitoring pipe 6. After recording multiple groups of relevant data of the auxiliary water pump 3, the auxiliary water pump 3 is turned off, the auxiliary water inlet valve 302 and the auxiliary drain valve 304 are closed. The system is set An auxiliary water pump 3 is installed. On the one hand, the head of the auxiliary water pump 3 running in the system is calculated by monitoring the output flow and the water pressure at the output end of the auxiliary water pump 3, and compared with the known actual head of the auxiliary water pump 3, the error size of the system is tested. According to the error situation of the system, the staff can calculate the various performance data of the tested cooling water pump more accurately, so as to make the use of the test system more accurate. On the other hand, the auxiliary water pump 3 is pre-tested to obtain multiple groups of data. The auxiliary water pump 3 is used as a standard water pump. The tested data can be used as reference data for the cooling water pump test data, which can more intuitively reflect the shortcomings of the cooling water pump, thereby making the test system more intuitive for cooling water pump testing. On the other hand, the auxiliary water pump 3 is pre-tested to obtain multiple groups of data. The auxiliary water pump 3 is used as a standard water pump. The tested data can be used as reference data for the cooling water pump test data, which can more intuitively reflect the shortcomings of the cooling water pump, thereby making the test system more intuitive for cooling water pump testing. The water valve 302, the auxiliary drain valve 304, the test drain valve 501 and the water lock valve 502 are all opened, and then the water change valve 603 is closed. The clean water in the water tank 1 and the water tank 2 can be discharged through the auxiliary water pump 3, which makes it convenient to replace the water in the water tank 1 and the water tank 2, thereby improving the convenience of replacing clean water and cleaning the test system. Then, the cooling water pump to be tested is placed in a limit frame 705 at the end of the delivery component 7, and the cooling water pump is supported by the carrier plate 706. The gear 702 is driven to rotate by the driving motor 704, and the transmission chain 703 is driven by rotating the gear 702. The transmission chain 703 drives the cooling water pump to move through the limit frame 705 and the carrier plate 706, and moves the cooling water pump to the top Above the lifting assembly 8, the first hydraulic cylinder 802 drives the first hydraulic rod 803 to move, and the first hydraulic rod 803 drives the top plate 804 to move up and down, and moves the top plate 804 upward, and lifts the carrier plate 706 together with the cooling water pump upward through the top plate 804. After the cooling water pump is raised to a certain height, the second hydraulic cylinder 901 drives the second hydraulic rod 902 to move, and the second hydraulic rod 902 drives the clamping plate 903 to move. By moving the two clamping plates 903, the cooling water pump is clamped and fixed from both sides of the cooling water pump. After fixing the cooling water pump, the water inlet end of the cooling water pump is connected to the test water inlet pipe 4, and the water outlet end of the cooling water pump is connected to the test drain pipe 5. By using the drive motor 704 to drive, the carrier plate 706 and the limit frame 705 are moved.By moving the carrier plate 706 and the limit frame 705, the cooling water pump is sent to the test area. On the one hand, there is no need for manual lifting, which saves manpower, and the transmission through the transmission chain 703 can complete the test of multiple cooling water pumps more quickly, thereby improving the efficiency of the test system. On the other hand, a lifting component 8 is set at the bottom of the delivery component 7, and the first hydraulic cylinder 802 is used to drive the cooling water pump on the carrier plate 706, so that the cooling water pump can reach the test area more accurately. By setting a water lock valve 502, after the cooling water pump test is completed, the water lock valve 502 is closed to prevent the clean water in the pipeline from flowing out. On the one hand, it avoids getting the outside of the system and the cooling water pump wet, and reduces the cleaning work after the system test. And further improve the convenience of using the system, on the other hand, reduce the waste of clean water for testing, and save the cost of using the system. Finally, after the cooling water pump is connected to the system, the water lock valve 502 and the test drain valve 501 are opened, and the cooling water pump is turned on. The cooling water pump draws clean water from the pumping chamber 201 of the water tank 2 through the test water inlet pipe 4, and sends the clean water into the monitoring pipe 6 through the test drain pipe 5. The flow rate of the cooling water pump is monitored by the flow sensor 601 on the monitoring pipe 6, the water inlet pressure of the cooling water pump is monitored by the water pressure sensor 602 installed on the test water inlet pipe 4, and the water outlet pressure of the cooling water pump is monitored by the water pressure sensor 602 installed on the monitoring pipe 6. The auxiliary water pump 3 monitored previously is used. The data is used as a reference, and according to the data changes of the monitored cooling water pump, the actual head and flow of the cooling water pump are analyzed and calculated to complete the test of the cooling water pump. When the system tests the cooling water pump, the cooling water pump draws out the water in the pumping chamber 201 through the test water inlet pipe 4, and sends the water to the transfer chamber 202 through the test drain pipe 5 and the monitoring pipe 6. The water in the transfer chamber 202 enters the drainage chamber 203 through the opening at the bottom of the baffle 208, and the water in the drainage chamber 203 enters the water tank 1 through the first drain port 206 and the second drain port 207. The water in the water tank 1 enters the pumping chamber 201 through the water gushing pipe 101. During the testing process of the cooling water pump, the test water is recycled. In this way, on the one hand, the test system Only a small amount of clean water is needed to carry out the test, and a large amount of water will not be wasted, thereby making the use of the test system more environmentally friendly. On the other hand, the test system is smaller in size and occupies less space, making it convenient to use in various venues. By setting a secondary water stabilizing plate 105 in the water tank 1, it plays a blocking role on the water, reduces the flow rate of the water, and makes the water flow back into the pumping chamber 201 more stable, reducing the interference of the water flow potential energy on the cooling water pump test, thereby improving the accuracy of the test system for the cooling water pump test. By setting a first water outlet 206 and a second water outlet 207 in the drainage chamber 203, the water flows through the first water outlet 206 and the second water outlet 207 are gathered on the primary water stabilizing plate 104 and collide with each other, which can effectively weaken the potential energy of the water flow.Under the obstruction of the first-level water stabilizing plate 104, the potential energy of the water flow is further weakened, thereby further reducing the interference of the water flow potential energy on the cooling water pump test, thereby further improving the accuracy of the system. By providing a filter frame 209, the test water can be filtered to prevent the test water from being used for a long time and containing impurities such as rust, thereby preventing the impurities in the water from damaging the test cooling water pump, thereby making the use of the test system more reliable. At the same time, it also prevents impurities in the water from affecting the accuracy of the test data of the test system, thereby further improving the accuracy of the test system.
