Description

Technical Field

[0001] This utility model relates to the field of water pump performance testing technology, specifically a fully automatic electric water pump performance testing bench. Background Technology

[0002] Electric water pumps in the new energy industry all use brushless motors for drive. During the R&D and software debugging stages of electric water pumps, it is necessary to test the comprehensive performance parameters of the water pump, such as flow rate, pressure difference, efficiency, power, and current. As an important data source for product development and software debugging, the efficiency and accuracy of this test greatly affect the progress of the project and the reliability of the product.

[0003] Existing complete performance testing systems for electric water pumps are large in area and expensive, making them unsuitable for use during product development and software debugging phases. While existing electric water pump test benches are inexpensive, they suffer from low testing efficiency and poor accuracy.

[0004] Existing electric water pump performance test benches use electronic water valves to change the flow rate in the pipeline, resulting in low efficiency and susceptibility to errors in pump performance testing. The electronic water valves can only change the flow rate by manually adjusting the opening size of the ball valve, reading and recording the parameters of the power supply, differential pressure gauge, flow meter, and other equipment at different flow rates, and then entering the recorded data into an Excel spreadsheet to generate test results. Throughout the testing process, adjusting the ball valve is cumbersome, and the recording and data entry processes are prone to errors. Therefore, it is necessary to develop a fully automated electric water pump performance test bench to improve the efficiency of pump performance testing while ensuring high accuracy and lower construction costs.

[0005] Existing water pump test benches construct a simple liquid loop. The liquid is stored in a water tank. After the electric water pump operates, it draws the liquid from the tank, which then flows through the constructed pipeline back to the tank, forming a liquid circulation loop. The liquid circulation loop path is: water tank → electronic water valve → differential pressure gauge → electric water pump → differential pressure gauge → electronic water valve → flow meter → electronic water valve → water tank. Electric water pump performance testing requires testing the pump's performance at different flow rates to ultimately generate a performance curve. Existing electric water pump performance test benches manually adjust the electronic water valve to change the liquid flow rate in the pipeline, observing and recording the power supply current, differential pressure gauge reading, and flow meter reading. This invention, after setting the operating program, will automatically adjust the liquid flow rate in the pipeline, and the parameter acquisition card will read and record the power supply current, differential pressure gauge reading, and flow meter reading, ultimately automatically generating an electric water pump performance curve.
