PERFORMANCE MONITORING AND FAULT DIAGNOSIS ON THE FUEL PUMP

A fundamental principle and a method of performance monitoring and fault diagnosis of the fuel pump, based on the analyses of general faults of the fuel pump, are proposed. They are fulfilled by the microcomputer and operational region diagram of the fuel pump. At the same time, a life prediction method which estimates the service life of the fuel pump by means of the historical data of measured parameters is introduced too. Finally, the satisfactory results are obtained by testing study of the axial piston pump.This system has the functions of automatic monitoring, quick diagnosis, trend analysis and condition prediction. It can effectively increase operational reliability and safety of the fuel pump. It is a useful way to ensure normal operation of the fuel pump.
