Abstract: In order to solve the problems of the weakness of current designed brushless fuel pump detection system and the detection of quality in production process, the test system was investigated. After the analysis of the working principle and test method of fuel pump, the system was established, which was based on Siemens PLC, touch win, pressure sensor, flow sensor and so on, and the VB6.0 was used to design the computer software,ladder diagram to PLC program. The known parameters fuel pump was evaluated on the test system, the precision and test error of system were determined. The experimental results show that the designed test system has the advantages of high precision, long life, easy to operate,conduce to the design of brushless fuel pump.
