In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

1 to 5 , the water pump testing device provided in the present application includes a mounting assembly 100, a water inlet pipe 200, a water outlet pipe 300 and a detection member 400. The mounting assembly 100 includes a first mounting member 110 and a second mounting member 120. At least one of the first mounting member 110 and the second mounting member 120 moves relative to the other so that the first mounting member 110 and the second mounting member 120 are closer to or farther away from each other.

At least one of the first mounting member 110 and the second mounting member 120 is provided with a plurality of mounting portions 111 which are nested and connected in sequence, and each mounting portion 111 is respectively used to be connected to the water inlet 11 or the water outlet 12 of the water pump 10 to be tested with different calibers, and the mounting portion 111 is connected to the water inlet pipe 200 or the water outlet pipe 300.

The detection member 400 is connected to the water outlet pipe 300 to detect at least one of the water pressure and flow rate on the water outlet pipe 300 .

It can be understood that at least one of the first mounting member 110 and the second mounting member 120 moves relative to the other. In specific implementation, the first mounting member 110 and the second mounting member 120 can be connected by a hydraulic cylinder. For example, the hydraulic cylinder can drive the first mounting member 110 to move relative to the second mounting member 120 along the positive direction of Y shown by the arrow in Figure 2, so that the first mounting member 110 and the second mounting member 120 move away from each other; the hydraulic cylinder can drive the first mounting member 110 to move relative to the second mounting member 120 along the reverse direction of Y, so that the first mounting member 110 and the second mounting member 120 approach each other; the hydraulic cylinder can also drive the second mounting member 120 to move relative to the first mounting member 110 along the positive direction of Y, so that the first mounting member 110 and the second mounting member 120 approach each other; the hydraulic cylinder can also drive the second mounting member 120 to move relative to the first mounting member 110 along the reverse direction of Y, so that the first mounting member 110 and the second mounting member 120 move away from each other. As long as the first mounting member 110 and the second mounting member 120 can be brought closer to or farther away from each other, the embodiment of the present application does not impose too many restrictions on this.

It should be noted that a controller 800 may also be provided to establish communication connection between the controller 800 and the hydraulic cylinder, and the hydraulic cylinder may be driven to move by the controller 800 to adjust the distance between the first mounting member 110 and the second mounting member 120 .

Since the water inlet 11 and the water outlet 12 of the vertical water pump are located on the same axis, when the vertical water pump is tested, the first mounting member 110 and the second mounting member 120 are close to each other and can jointly clamp the vertical water pump to be tested. After the test is completed, the first mounting member 110 and the second mounting member 120 are separated from each other and the vertical water pump can be released.

At least one of the first mounting member 110 and the second mounting member 120 is provided with a plurality of mounting portions 111 which are nested and connected in sequence. For example, a plurality of mounting portions 111 may be provided on the first mounting member 110, and the first mounting member 110 is connected to the water inlet 11 of the water pump 10 to be tested via the mounting portion 111, and the mounting portion 111 is connected to the water inlet pipe 200; a plurality of mounting portions 111 may also be provided on the second mounting member 120, and the second mounting member 120 is connected to the water outlet 12 of the water pump 10 to be tested via the mounting portion 111, and the mounting portion 111 is connected to the water outlet pipe 300. The embodiments of the present application do not impose too many restrictions on this.

It should be noted that, since the mounting parts 111 are nested in sequence, the size of each mounting part 111 increases from the inside to the outside, that is, each mounting part 111 has a different size. For water pumps 10 to be tested with different calibers, the water inlets 11 or water outlets 12 of different water pumps 10 to be tested can be connected to different mounting parts 111, which is convenient for operation and improves test efficiency.

It should also be noted that the detection member 400 is connected to the water outlet pipe 300, and the detection member 400 detects the water pressure on the water outlet pipe 300, that is, detects the water outlet pressure of the water pump. By comparing the actually measured water outlet pressure with the design pressure, it can be evaluated whether the performance of the water pump meets the design specifications. The detection member 400 detects the flow rate on the water outlet pipe 300 of the water pump, which is one of the important parameters for evaluating the performance of the water pump. The hydraulic efficiency and overall efficiency of the water pump can also be calculated through the measured flow rate and pressure.

In some embodiments, as shown in FIG. 3 , two adjacent mounting portions 111 are slidably connected to each other.

It can be understood that the sliding connection allows relative movement between adjacent mounting portions 111. When installing the water pump 10 to be tested, the mounting portion 111 that matches the water inlet 11 or the water outlet 12 of the water pump 10 to be tested is slid relative to the mounting portion 111 adjacent to it to extend the mounting portion 111 so that the mounting portion 111 is connected to the water inlet 11 or the water outlet 12 of the water pump 10 to be tested.

It should be noted that the lengths of the mounting portions 111 can be consistent, and a sliding connection is adopted between two adjacent mounting portions 111. This design can provide flexible extension or retraction of the mounting portions 111 to be suitable for water pumps 10 to be tested with different calibers, is easy to operate, and improves test efficiency.

In some embodiments, as shown in FIG. 3 , each mounting portion 111 has a first stopper 1111 and a second stopper 1112 at both ends thereof, and two adjacent mounting portions 111 are connected via the first stopper 1111 of one and the second stopper 1112 of the other.

It can be understood that when one of two adjacent mounting portions 111 slides relative to the other to extend out of the other, the first limit member 1111 and the second limit member 1112 can provide mechanical support and fixation for the two adjacent mounting portions 111 to prevent the two adjacent mounting portions 111 from detaching, thereby enhancing the connection stability between the adjacent mounting portions 111 and improving the reliability of the mounting portions 111.

In some embodiments, as shown in FIG. 2 and FIG. 3 , a threaded section 1113 is provided on the outer wall of the mounting portion 111 , and the threaded section 1113 is used to connect with the water inlet 11 or the water outlet 12 of the water pump 10 to be tested.

The threaded section 1113 is used to connect with the water inlet 11 or the water outlet 12 of the water pump 10 to be tested. In specific implementation, the threaded section 1113 can be directly connected to the water inlet 11 or the water outlet 12 of the water pump 10 to be tested; or a threaded sleeve can be used to connect the threaded section 1113 of the mounting portion 111 to the water inlet 11 or the water outlet 12 of the water pump 10 to be tested; or other methods can be used to connect the threaded section 1113 to the water inlet 11 or the water outlet 12 of the water pump 10 to be tested, and the embodiments of the present application do not impose too many restrictions on this.

By setting the threaded section 1113, the connection between the installation component and the water pump 10 to be tested can be ensured to be stable and not prone to loosening or falling off; it can also provide good sealing to prevent liquid leakage at the connection to ensure the accuracy of the measurement results; and the connection method is simple, which is convenient for quick installation and disassembly, and can improve the test efficiency.

In some embodiments, as shown in Figure 2, the installation assembly 100 also includes a third installation member 130, which is connected to the second installation member 120. The third installation member 130 is used to communicate with the water inlet 11 of the water pump 10 to be tested, and the water outlet pipe 300 is used to communicate with the water outlet 12 of the water pump 10 to be tested.

Since the water inlet 11 of the horizontal water pump is in the horizontal direction and the water outlet 12 of the horizontal water pump is in the vertical direction, when testing the horizontal water pump, the third mounting member 130 can be connected to the water inlet 11 of the horizontal water pump, and the water outlet pipe 300 can be connected to the water outlet 12 of the horizontal water pump, thereby realizing the testing of the horizontal water pump.

It should be noted that a plurality of sequentially nested and connected mounting portions 111 may also be provided on the third mounting member 130 , and each mounting portion 111 is used to be connected to the water inlet 11 of a horizontal water pump to be tested with a different caliber.

In some embodiments, as shown in Figure 2, the installation assembly 100 also includes a first connecting pipe 140 and a second connecting pipe 150, and valves 160 are provided on the first connecting pipe 140 and the second connecting pipe 150. The first connecting pipe 140 is used to connect the second mounting member 120 with the water outlet pipe 300. Specifically, the mounting portion 111 on the second mounting member 120 can be connected to the water outlet pipe 300 through the first connecting pipe 140, and the second connecting pipe 150 is used to connect the water outlet 12 of the water pump 10 to be tested with the water outlet pipe 300.

Specifically, when testing the vertical water pump, the first mounting member 110 and the second mounting member 120 can be driven close to each other so that the first mounting member 110 and the second mounting member 120 jointly clamp the vertical water pump to be tested, close the valve 160 on the second connecting pipe 150, and open the valve 160 on the first connecting pipe 140 to connect the second mounting member 120 with the water outlet pipe 300.

When testing a horizontal water pump, the first mounting member 110 and the second mounting member 120 are driven to approach each other so that the first mounting member 110 and the second mounting member 120 are connected, and then the water inlet 11 of the horizontal water pump to be tested is connected with the third mounting member 130, the valve 160 on the first connecting pipe 140 is closed, and the valve 160 on the second connecting pipe 150 is opened to connect the water outlet 12 of the horizontal water pump to be tested with the water outlet pipe 300. Therefore, the water pump testing device provided by the present application can be used to test both vertical water pumps and horizontal water pumps, which improves the application scope of the device.

In some embodiments, as shown in FIG. 2 , the detection component 400 is at least one of a pressure gauge 410 and a flow meter 420 .

Specifically, a pressure gauge 410 may be provided on the water outlet pipe 300 , a flow meter 420 may be provided, or the pressure gauge 410 and the flow meter 420 may be provided in sequence, and the embodiment of the present application does not impose too many restrictions on this.

It can be understood that the pressure gauge 410 is used to measure the outlet pressure of the water pump. By detecting the outlet pressure, it can be understood whether the water pump can provide the required pressure to meet the system requirements, and by comparing the actual measured outlet pressure with the design pressure, it can be evaluated whether the performance of the water pump meets the design specifications. The flow meter 420 can be used to verify whether the design parameters of the water pump and the system meet the actual operation requirements, so as to make necessary adjustments and optimizations.

It should be noted that by using the pressure gauge 410 and the flow meter 420 simultaneously, the performance of the water pump can be comprehensively evaluated, including key parameters such as flow, pressure, and efficiency, which helps to fully understand the operating status of the water pump.

It should also be noted that an electric valve 430 can be provided between the pressure gauge 410 and the flow meter 420. The electric valve 430 can achieve precise control of the flow rate to test the performance of the water pump under different working conditions. By controlling the flow rate, the electric valve 430 can also indirectly adjust the pressure in the system to ensure that the pressure is within a preset range. The electric valve 430 can be remotely operated through the control system to achieve automated control to improve the convenience and safety of the test process.

In some embodiments, as shown in Figures 1 and 2, the water pump testing device also includes a water pool 500, the water pool 500 includes an inlet section 510, an isolation section 520 and a water outlet section 530, the inlet section 510 is connected to the outlet section 530, the inlet section 510 is connected to the inlet pipe 200, the outlet section 530 is connected to the outlet pipe 300, and the detection component 400 is disposed in the isolation section 520.

It can be understood that the isolation section 520 can prevent the liquid in the water inlet section 510 and the water outlet section 530 from entering the detection member 400, thereby ensuring the normal operation of the pressure gauge 410 and the flow meter 420.

The water inlet section 510 is connected to the water outlet section 530. When the water pump is tested, the water in the water inlet section 510 enters the water pump 10 to be tested through the water inlet pipe 200, then flows into the water outlet section 530 through the water outlet pipe 300, and finally returns to the water inlet section 510, thereby forming a cycle and improving the utilization rate of water.

In some embodiments, as shown in FIG. 2 , the water pump testing device further includes a vacuum pump 600 . The vacuum pump 600 is connected to the water inlet pipe 200 . The vacuum pump 600 is used to evacuate the water inlet pipe 200 .

It should be noted that when the water level of the water inlet pipe 200 is lower than the water inlet 11 of the water pump 10 to be tested (that is, the water level entering the water inlet pipe 200 from the water inlet section 510 is lower than the water inlet 11 of the water pump 10 to be tested), the water inlet pipe 200 is evacuated by the vacuum pump 600, which can effectively remove the air in the water inlet pipe 200 and prevent the occurrence of cavitation. The presence of air will also affect the measurement accuracy of pressure and flow. By evacuating and removing air, the accuracy and reliability of the measurement data can be ensured.

Before starting the water pump, vacuuming by the vacuum pump 600 can reduce the air resistance in the water inlet pipe 200, making it easier to start the water pump. Removing the air in the water inlet pipe 200 can ensure that the water pump can quickly establish normal flow and pressure when starting, avoiding startup failure or delay. By vacuuming to remove air, the water flow state in the water inlet pipe 200 can also be optimized to reduce flow resistance.

In some embodiments, as shown in FIG. 2 , the water pump testing device further includes a drying assembly 700 , the drying assembly 700 includes a dryer 710 and a slide rail 720 , the dryer 710 is disposed on one side of the second mounting member 120 , and the slide rail 720 is disposed between the dryer 710 and the second mounting member 120 .

It is understandable that after the water pump test is completed, there may be residual moisture in the water pump. If it is not dried in time, this moisture may cause corrosion and rust to the equipment. Dryer 710 can quickly dry the equipment to prevent this from happening. By drying in time, the long-term damage of moisture to the equipment can be reduced, thereby extending the service life of the equipment.

The slide rail 720 can quickly move the tested water pump to one side to facilitate the testing of the next water pump 10 to be tested, thereby reducing waiting time and improving testing efficiency. In a specific implementation, after the first vertical water pump clamped by the first mounting member 110 and the second mounting member 120 is tested, if it is necessary to test the next vertical water pump, the first vertical water pump can be moved to one side by the slide rail 720 so that the first mounting member 110 and the second mounting member 120 can clamp the second vertical water pump to be tested together; or, after the first vertical water pump clamped by the first mounting member 110 and the second mounting member 120 is tested, if it is necessary to test the horizontal water pump, the first vertical water pump can be moved to one side by the slide rail 720, and then the first mounting member 110 and the second mounting member 120 can be driven close to each other so that the first mounting member 110 and the second mounting member 120 are connected, and then the water inlet 11 of the horizontal water pump to be tested is connected with the third mounting member 130, and the water outlet 12 of the horizontal water pump to be tested is connected with the water outlet pipe 300. It should be noted that the slide rail 720 may be arranged along the X direction indicated by the arrow in FIG. 2 , that is, the extension direction of the slide rail 720 is perpendicular to the movement direction of the first mounting member 110 or the second mounting member 120 .

It can be understood by those skilled in the art that the water pump testing device provided by the present application is provided with a mounting assembly 100, a water inlet pipe 200, a water outlet pipe 300 and a detection member 400, wherein the mounting assembly 100 includes a first mounting member 110 and a second mounting member 120, and at least one of the first mounting member 110 and the second mounting member 120 moves relative to the other, so that the first mounting member 110 and the second mounting member 120 are close to each other or away from each other, so as to clamp or release the water pump 10 to be tested together. The detection member 400 is connected to the water outlet pipe 300 to detect the water pressure or flow on the water outlet pipe 300 of the water pump to be tested. At least one of the first mounting member 110 and the second mounting member 120 is provided with a plurality of mounting portions 111 which are nested and connected in sequence. Since the mounting portions 111 are nested in sequence and have different sizes, for water pumps 10 to be tested with different calibers, the water inlet 11 or the water outlet 12 of the water pump 10 to be tested can be connected to different mounting portions 111, which facilitates operation and improves test efficiency.
