Using Lubricating Oil Filter Debris Analysis to Monitor Abnormal Wear of Aero-Engine
With the installation of finer oil filters in the lubrication system of aero-engine, the traditional wear analysis techniques such as Rotating Disc Electrode Atomic Emission Spectrometry Analysis (RDE-AES) become less efficient at detecting abnormal wear failure caused by large debris. These filters capture large debris containing large amounts of tribological information about the operation of an aero-engine. Removal and analysis of the filter debris has proved to be an effective tool for aero-engine health management by determining wear modes and observing failure progression providing long lead times for maintenance. An automated aero-engine oil filter debris analysis system was recently developed. This instrument could efficiently complete filter core washing, debris amount and size distribution analysis, and prepare a patch of the debris for further composition analysis.
