Introduction of Control Principle of Air Compressor in Zhengxu Line and Research on Lubricating Oil Emulsification
[Purposes]Due to the small amount of air used by vehicles in the initial stage of subway com-missioning and operation,the operation rate of air compressor is low,and the water in the lubricating oil of air compressor cannot be discharged in time,which is easy to lead to the emulsification of lubricating oil,thus affecting the normal use and life of air compressor.As air compressor is the air source of vehicle braking system,lubricating oil emulsification also causes security risks to vehicle braking performance.[Methods]This paper expounds the working principle of Zheng Xu line air compressor,analyzes the rea-sons for emulsification of air compressor oil,and studies the effect of air compressor operating rate adjust-ment device on preventing oil emulsification of air compressor.[Findings]The research results show that:by setting the air compressor working rate adjustment device on the vehicle,the operation rate of the air compressor can be effectively improved,the water in the lubricating oil is discharged in time,the emulsi-fication of the air compressor lubricating oil is improved,and the reliability of the vehicle is guaranteed.[Conclusions]The research results can provide a reference for the subsequent reconstruction of the air supply system of newly built vehicles or existing vehicles.
