基于直读铁谱技术的航空发动机磨损状态监测

Aero-engine Wear Condition Monitoring by Direct Reading Ferrography

利用线阈法分析某型航空发动机润滑油样的直读铁谱数据,提出油液直读铁谱分析诊断标准。诊断实践证明,该标准应用于航空发动机磨损状态监测效果较好。

Three threshold-lines evaluation was used to analyze direct reading ferrograph data of lubricating oil from aero-engine. The analytical and diagnostic criterions of oil were put forward. The diagnostic practices prove that the criterions have a good effect and can be used in aero-engine wear condition monitoring.
