某型高涵道比涡扇发动机滑油压力低故障分析

摘要

In order to troubleshoot the low oil pressure fault of one turbofan engine,the working principles of oil system an d oil pressure indicating system are expounded. Then the possible causes for this fault are analyzed in detail, and the flow of troubleshooting is developed according to the reliability of parts and the complexities of inspecting work.%为了对某型民用涡扇发动机滑油压力低故障进行排故分析，阐述了该发动机滑油系统的工作原理以及滑油压力指示原理，分析了滑油压力低的可能原因，并按照系统部件的可靠性和检查工作的复杂程度给出了滑油压力低的排故流程，可为航线机务人员提供参考。
