Research on Failure Analysis and Preventive Measures of EMU Train Solenoid Valve
This article proposes a failure analysis method and preventive improvement measures for electromagnetic valves of EMU train.By simulating the actual application environment,the failure of the solenoid valve is replicated to determine the mechanism and cause of the failure affecting the solenoid valve.The results indicate that the main failure mode of the solenoid valve in high temperature and humidity environments is jamming and air leakage,with internal manifestations of structural detachment,foreign objects,and oil carbonization.Attention should be paid to sealing and process sampling in daily use.The research of this project also provides feasible methods for preventing solenoid valve failure.
