In the case of a high-temperature failure of the air compressor with a built-in oil fine separator, the high-temperature failure caused by lack of oil may cause a fire accident, seriously affecting the safe operation of the locomotive. In order to reduce the high-temperature failure of the locomotive air compressor with a built-in oil fine separator and eliminate air compressor fire accidents, through cause analysis, it is found that the high-temperature failure of the air compressor with a built-in oil fine separator due to lack of oil occurs more frequently.
