Development of Debris Image On-line Monitoring System for Contaminated Fluid

Debris in the lubrication or hydraulic oil carries many information about the working state and failure of the machine system. By on line monitoring and analyzing the debris in the working oil, the wear state of machine and the contamination state of hydraulic system can be obtained. Based on the synthetic application of the techniques of the micro imaging and computer vision, a debris image on line monitoring and analyzing system for contaminated fluid is developed, and the design project and design principle of the system are also presented. Through theoretical and experimental analyzing, the main performance indexes of the system are obtained. The system provides an advanced method for the status inspection and fault diagnosis of aero engines based on the oil analyzing.
