In view of the problems of low automation degree and single function of the current water pump test system,with the industrial control machine as the carrier,an electronic water pump performance test system was developed based on the cooperative control mode of upper computer and lower computer.In the lower computer of the electrical system,PLC was adopted to control the proportional valve,vacuum pump and other electrical components to control the test process;the temperature controller was used to heat rods,by which the temperature of the test medium could be automatically adjusted;sensor data were collected and transmitted to the upper computer based on Advantech high-precision data acquisition module;in the upper computer,LabVIEW was taken as the platform to develop test system software to realize data interaction, data processing and report generation.The results show that the system can be used to realize the highly automatic testing of flow-head,flow-power,flow-cavitation allowance and other performance curves of different power electronic water pumps at different temperature.
