摘　　要：针对HX_N3型机车曲轴箱超压问题进行深入分析,通过研究车载曲轴箱压力监测装置,实现实时监测记录曲轴箱压力,为工程技术人员提供相关数据依据,对异常数据规律进行分析,找出原因,预防柴油机部件故障发生。The crankcase overpressure problems of HX_N3 locomotive are analyzed deeply. The pressure of the crankcase is monitored and recorded in real time by studying the crankcase pressure monitoring on-board device,which provides the relevant data basis for the engineering technical personnel to analyze the abnormal data laws,find out the reason and prevent the failure of the component in the diesel engine.
