地铁列车空压机故障分析及逻辑优化

Fault Analysis and Logic Optimization of the Air Compressor for Metro Train

针对南京地铁1号线增购车辆在运营初期出现2台空压机同时不工作,导致主风管压力持续降低,最后低于紧急制动压力阈值这一危险情况,深入分析其相关原因,并对空压机的启动逻辑进行优化。从根源上解决了2台空压机同时不工作这一问题。

With regard to the problem happened in Nanjing metro line 1 added vehicle project,which is two air compressors failed to work at the same time during initial operation,causing a risk situation at the main pipe air pressure deceasing to the pressure threshold of emergency brake.The paper analyzed the related root cause and optimized the compressor start logic to solve the problem originally.
