浅析波音737NG飞机液压系统低压灯亮

The hydraulic system of the Boeing 737NG aircraft low Pressure lights

该论文主要针对波音737NG飞机液压系统低压灯亮的情况进行总结分析,在航线工作中维修人员经常会遇到由于液压系统低压灯亮的故障而导致航班长时间延误和取消,按照最低放行清单(MEL)手册对飞机液压系统的发动机驱动泵(EDP)和电动马达泵(EMDP)是不能失效的,如果失效一个也不能放行。

This paper summarizes the analysis is according to the condition of low--voltage lights of the Boeing 737NG aircraft hydraulic system, in the route work repair personnel often encounter caused flight delays and cancellations due to long time faults of the hydraulic systems of low--voltage lights, in accordance with the minimum inventory （MEL） Handbook of hydraulic system of aircraft engine driven pump （EDP） and electric motor driven pump （EMDP） is not failure, if a failure can not dispatch.
