摘　　要：介绍了9E燃气轮机投产以来润滑油系统发生的主要故障,包括油质变差、油压低、油温高及管路漏油等。分析了故障产生的原因,主要是润滑油因高温氧化而过快老化或部分设备有内漏等,提出了在运行中应加强油质监控,定期检查油泵出口逆止阀的磨损情况及管路泄漏情况,及时更换润滑油滤芯。The major failures of the lubrication-oil system in a 9E gas turbine are described, including deteriorated oil quality, low oil pressure high oil temperature and oil leakage in the pipeline and so on. The reasons of the failures are mainly due to the quick ageing of lub-oil, caused by it＇s high temperature oxidation or leakage in some equipment. Therefore, during operation, oil quality monitoring should be strengthened, wear status of the oil pump outlet check valve, as well as the pipeline leakage should be inspected periodically and the filter elements should be replaced timely.
