摘　　要：针对某型燃油泵控制油路密封端面泄漏故障,运用Pumplinx软件对控制油路流场进行仿真分析,得出了气蚀是导致密封端面漏油的主要原因,并对密封端面结构进行优化设计,最后,通过试验验证了改进措施的有效性。Focus on the leakage faults of seal face for the fuel pump,Established simulation model of control oil based on Pumplinx software,and concluded that the main reason for leakage faults was the cavitation damage of seal face,and put forward the corresponding improvement measures for seal face.Finally,through the experiment verify the correctness of the relevant improvement measures.
