Since the measurement accuracy and efficiency of the traditional artificial pump test method is low, a distributed pump automatic test system was designed to automatically complete various tests such as pump performance test, type (cavitation) test and idling test. Firstly, the inlet and outlet valves were controlled, and then the inlet pressure, outlet pressure, motor speed, and voltage, current, and active power parameters of the pump under various flow points of the pump were measured; Secondly, according to GB/T3216-2016/ISO 9906:2012, test results such as head, efficiency and cavitation margin were calculated; Finally, the corresponding test report was generated and stored, and the indicator characteristics of the pump were automatically determined. The system has been put into practical use. The system testing show that the system can greatly reduces pump test time, improves test efficiency and test accuracy.
