以ＰＷ４０００型发动机为例，在对滑油系统的功用及常见故障进行分析的基础上，提出了利用屑末分析和状态参数两种模式对滑油系统进行状态监控的方案，并对状态信息的来源、监控参数的选择、监控系统的功能等进行了分析和讨论。ＰＷ４０００发动机是用于波音７４７—４００ 和 Taking PW4000 engine as an example, based on the analysis of the function and common faults of the lubricating oil system, a scheme of condition monitoring of the lubricating oil system by using two modes of debris analysis and state parameters is put forward, and the status information Source, the choice of monitoring parameters, the function of the monitoring system were analyzed and discussed. The PW4000 engine is for the Boeing 747-400 and
