Design and implementation of wind resistance load testing system for electronic water pumps

Aiming at the limitation of factory testing of electronic water pump, the wind resistance load testing system of electronic water pump with gas as medium, combined with STM32 embedded system and various sensors is designed. The hardware part adopts STM32 as the main control chip, and designs the corresponding control circuit and signal acquisition circuit, and develops the corresponding upper computer software combined with VS2017 and QT framework, so as to realize the system automatic test. The system performs pump testing by applying reverse airflow, with fast testing rate and no additional pump cleaning work after the test is completed, which improves the efficiency of pump factory testing.
