Problems solved by technology

The disadvantage of the above two methods is that they can only collect abrasive particles statically, and cannot conduct timely online active sensing and effective classification of lubricating oil abrasive particles, so it is also impossible to conduct timely online diagnosis of failure modes based on the collected lubricating oil abrasive particles
[0006] In addition, there are two main types of lubricating oil monitoring sensors with abrasive particle collection function: Gill sensor and QDM sensor, which realize the integration of abrasive particle collection and monitoring, but their defects are also obvious. They can only collect a small amount of abrasive particles and cannot monitor non-metallic Abrasive particles

Abstract

The invention relates to the technical field of engine lubricating oil filtering, in particular to a multifunctional lubricating oil abrasive particle collecting film and an engine abrasion state diagnosis method, wherein the multifunctional lubricating oil abrasive particle collecting film comprises a porous film, a piezoelectric ceramic sensor, a supporting framework and an electrode; the supporting framework supports the porous film to unfold; and the piezoelectric ceramic sensor is arranged on the supporting framework. The multifunctional lubricating oil abrasive particle collecting film provided by the invention is mounted in a lubricating oil pipeline; the engine lubricating oil abrasive particles can be actively collected in an online whole drainage basin, the collected abrasive particles are actively sensed and orderly classified, bases are provided for abrasion state online recognition and diagnosis and situation observation, and the multifunctional lubricating oil abrasive particle collecting film is particularly suitable for the technical field of aero-engines and has important practical application value.

Description

technical field [0001] The invention relates to the technical field of engine lubricating oil filtration, in particular to a multifunctional lubricating oil abrasive particle collection film and a method for diagnosing the wear state of the engine. Background technique [0002] The lubricating oil system is one of the important components of the engine. The lubricating oil flows through the bearings and gears of the engine and other wear-prone areas. It is the "lifeblood" of the lubricating oil system. In addition to lubrication and cooling, it is also a rolling and sliding surface. Transport medium for abrasive abrasive particles. If the abrasive particles in the lubricating oil are not filtered and collected in time, it may cause secondary loss of the rotating parts and the lubricating oil system. Therefore, timely collection and analysis of abrasive particles in lubricating oil is conducive to timely and effective maintenance of engine rotating parts, avoiding the advers...
