滑油系统是涡轮发动机的重要保障系统,滑油压力低将导致机件无法得到充分润滑和冷却,进而失效。本文针对一起典型的FJ44-1A型涡扇发动机高空滑油压力低故障进行了分析,从滑油系统工作原理及发动机使用环境两个方面阐述了故障原因,为FJ44-1A发动机的使用维护提供了参考。
Oil system is an important guarantee system of turbine engine, low oil pressure will lead to mechanical parts can not be fully lubricated and cooled, and then failure. In this paper, a typical failure of the FJ44-1A turbofan engine with high oil pressure is analyzed. The causes of the failure are explained from the working principle of the oil system and the engine operating environment, which provide the use and maintenance of the FJ44-1A engine reference.
