During the process of the aeroengine rig test,advanced particle monitoring equipment was used in the lubricating oil system,and the particle monitoring experiment was carried out for the lubricating oil system by aeroengine bench to explore the variation of the particles in the lubricating oil system .The location and timing of the oil sampling was determined through the analysis of the lubricating oil system of a certain aeroengine bench.The standard of aeroengine lubricating oil particle monitor and control was determined by using threevalue evaluation,and an example was given to validate the standard.The result shows that the monitoring standard is reasonable and feasible,which provides a reference for monitoring the wear of engine parts and the pollution of lubricating oil system.
