Description

Technical Field

[0001] The utility model relates to the technical field of water pump testing, in particular to a water pump performance testing system. Background Art

[0002] Electronic water pumps are widely used in electric vehicles for powertrain cooling and are also used in the cooling systems of gasoline-powered vehicles, including turbocharger cooling circuits and intake air intercooling systems. In new energy vehicles, electronic water pumps primarily provide circulating cooling for the drive motor, electric components, and power batteries, ensuring that the engine and battery do not overheat. The electronic water pump uses the circular motion of the motor, which mechanically reciprocates the diaphragm inside the pump, thereby compressing and stretching the air within the pump chamber. This movement, through the action of a one-way valve, creates positive pressure at the outlet and a vacuum at the pump outlet, creating a pressure differential with the ambient atmospheric pressure. This pressure differential forces water into the water inlet and out the outlet. The kinetic energy transmitted by the motor continuously draws water in and out, resulting in a relatively stable flow rate, ensuring the normal operation of the vehicle.

[0003] Electronic water pumps are widely used in the automotive market. Different vehicle models and operating conditions require different performance parameters (flow rate and head) for the water pump. This requires setting performance indicators based on these requirements to verify whether the water pump meets these requirements. However, there is currently no comprehensive performance testing system on the market, so a system for testing the performance of automotive electronic water pumps is needed. Utility Model Content

The water pump performance testing system of the utility model has the ability to perform comprehensive performance testing on a water pump 15 to be tested, and has a reasonable structure and convenient operation.

[0030] Example 1:

[0031] like Figure 1-2 As shown, the water pump performance test system includes a frame 1 for support; a platform 2 that can slide back and forth in the horizontal direction is provided on the frame 1, and a mobile drive device 3 is provided to control its sliding back and forth; at one end of the platform 2 in the sliding direction, a water inlet pipe 14 is provided, one of the interfaces of which is facing the direction of the platform 2, and a pressure differential sensing valve 11 is connected in series to the water inlet pipe 14; a water outlet pipe 8 with one interface facing downward is provided on the side above the platform 2 near the water inlet pipe 14, and a flow meter 9, a flow regulating valve 10 and a pressure differential sensing valve 11 are connected in series to the water outlet pipe 8; a pressure differential gauge 12 is also provided, and the pressure differential gauge 12 is simultaneously connected to the pressure differential sensing valve 11 on the water inlet pipe 14 and the outlet pipe 8; a tooling 16 for detachably installing the water pump 15 to be tested is provided on the platform 2. After the water pump 15 to be tested is fixed by the tooling 16, the water inlet of the water pump 15 to be tested faces the interface of the water inlet pipe 14.

[0032] When the performance test of the water pump 15 to be tested is carried out by this water pump performance test system, first, the end of the water inlet pipe 14 away from the platform 2 is connected to the water source, and then the end of the water outlet pipe 8 away from the platform 2 is externally connected to lead the water pumped during the test outward; then the water pump to be tested 15 can be installed on the platform 2 by fixing with screws (tooling 16) or the like, and the water pump is controlled to move toward the water inlet pipe 14 by the driving device. Since the interface of the water inlet pipe 14 and the water inlet of the water pump 15 to be tested are relative, the platform 2 can move to a certain position so that the water inlet of the water pump 15 to be tested can be naturally connected with the interface of the water inlet pipe 14.

[0039] When performing a performance test on the water pump 15 to be tested using the present water pump performance test system, first, a certain amount of water is filled into the circulating water tank 26; then, the water pump 15 to be tested is installed on the platform 2, and the water pump is controlled by the driving device to move toward the water inlet pipe 14. Since the interface of the water inlet pipe 14 and the water inlet of the water pump 15 to be tested are opposite to each other, after the platform 2 is moved to a certain position, the water inlet of the water pump 15 to be tested can be naturally docked with the interface of the water inlet pipe 14, and the hose 13 is connected to the water outlet of the water pump 15 to be tested; then, the water pump 15 to be tested can be powered on for testing.

After the water pump 15 to be tested is fixed by the tooling 16, the water inlet of the water pump 15 to be tested faces the interface of the water inlet pipe 14.

[0048] It also includes a circulating water tank 26. The interface of the water inlet pipe 14 at the end away from the platform 2 is connected to the interior of the circulating water tank 26. A first switch valve 27 is provided on the water inlet pipe 14. The interface of the water outlet pipe 8 at the end away from the platform 2 extends from the upper part of the circulating water tank 26 to the inside of the circulating water tank 26.

The circulating water pump 24 is generally fixed to the frame 1 and is located below the water collection tank 21.

[0053] On this basis, the platform 2 and the mobile drive device 3 that drives the platform 2 are the main hands-on operation area of the test tool 16.

[0056] During the test, a differential pressure gauge reads the pressure changes at the differential pressure sensing valves on the inlet and outlet pipes. This allows for observation of water pressure changes at the inlet and outlet of the pump under test, assessment of dust generation, and, over a period of time, monitoring of the pump's health. The flow meter also allows for monitoring the pump's metering and delivery capacity. The flow control valve can also be used to adjust the pump's flow rate, enabling convenient observation and testing.
