摘要
针对某型涡轴发动机科研阶段地面台架出厂试验中出现的鼓风机漏油故障,采用故障树法,根据该型发动机结构特点,详细分析了故障的可能原因,建立了漏油故障树,通过分解检查和设计复查对底事件进行排查,确定了鼓风机漏油的原因,并进行了试验验证,排除了故障,对该型发动机故障排除具有参考价值。
For the air blower oil leakage of turboshaft engine appearing during research phase,the fault causes are analyzed in detail with fault tree method based on the structure features of the engine.Then a fault tree of oil leakage is established.The bottom events are checked by overhauling and design review,and the cause of the oil leakage is diagnosed.It is proved that the fault is removed through the verification test.It gives a reference to the trouble removal of oil leakage of the engine.
