Abstract:

A set of oil pump performance testing system based on automotive oil pump is designed for the problems of complex operations,data inaccuracy and low efficiency in the handle testing of oil pump.With the help of LabVIEW environment and data acquisition card,this testing system tests the automobile oil pump performance with NI-USB 6210 data acquisition card to collect fuel pressure,fuel flow,pump working voltage and current parameters.PC interface is compiled by LabVIEW to realize the control parameters setting,pump performance evaluation,data display,storage,query and other functions based on historical records.The experimental results show that the testing time of this system is reduced by 90% with dramatically improved accuracy and efficiency compared with the traditional test method.
