Fault Analysis of Insufficient Oil Supply Flow in Certain Type of Pump Regulator
A certain engine stopped abnormally due to a problem with the pump regulator.In response to this fault,this paper elaborates on the functional principle of the pump regulator,the diagnostic conclusions before and after the fault occurred,and the troubleshooting methods.A fault tree is established to investigate the underlying events one by one,and it is determined that the cause of the engine's abnormal stop fault is the abnormal blockage of the throttle nozzle of the pump regulator.Then,targeted improvement measures are formulated to upgrade and improve the pump regulator to avoid similar faults from happening again.
