Abstract

A quick ferrographic analysis method based on digital video includes the following steps: adopting a designed flow-controllable micro-channel device and a ferrographic microscope to be integrated into a whole; enabling a diluted oil sample to pass through a micro-channel directly; acquiring a clear abrasive particle image by regulating the focal length of the ferrographic microscope; sending the moving video of abrasive particles in the micro-channel to a computer through a digital camera; directly analyzing image frames through computer software to realize accurate positioning and characteristic identification of a plurality of characteristic abrasive particles to form a characteristic library. As abrasive particles tumble in the fluid, spatial characteristics of the abrasive particles from different perspectives can be acquired through characteristic identification of different frame images; through digital video image acquisition and fast computer automatic analysis, the advantages of an off-line analysis technology and an on-line analysis technology are combined, a novel method of acquiring abrasive particle characteristics on the basis of dynamic video is proposed, and real-time, continuous, high-accuracy and efficient on-line monitoring for the abrasion condition of the equipment is realized.

Description

technical field

[0001] The invention belongs to the field of on-line monitoring of wear state and research of wear mechanism, in particular to a fast ferrography analysis method based on digital video, which is used for state monitoring and analysis of mechanical systems. Background technique

[0002] Ferrography analysis, as an important means of monitoring and fault diagnosis of mechanical equipment wear status, has been developed in the industrial field for nearly 50 years, and has become a standardized technology for equipment monitoring and testing, and because it can realize direct wear mechanism analysis, it is widely used in the field of commercial analysis. be more and more widely used.

[0003] The traditional ferrographic analysis technology uses a high-gradient magnetic field to separate the abrasive particles in the oil through an analytical ferrographic instrument, deposits them on the ferrographic substrate in a regular arrangement, and then obtains a clear im...
