Image acquisition-based lubricating oil abrasive particle on-line monitoring device and work method thereof

Abstract

The invention discloses an image acquisition-based lubricating oil abrasive particle on-line monitoring device and a work method thereof. The device comprises an oil-liquid separation system and an image acquisition system. The oil-liquid separation system separates an oil liquid according to sizes of abrasive particles in the oil liquid to obtain two groups of oil liquids with abrasive particle sizes less than Num and abrasive particle sizes greater than Num. The number and morphology of abrasive particles in the two groups of the oil liquids are respectively acquired by the image acquisition system. The device and method effectively prevent abrasive particle chaining phenomenon of off-line ferrograph analysis, prevent large abrasive particle-caused shielding of small abrasive particles in on-line video monitoring and realize simultaneous monitoring of the number of the abrasive particles and morphology characteristic information.

Description

technical field [0001] The invention relates to an on-line monitoring method and device for lubricating oil abrasive particles, and relates to the field of on-line analysis of ferrography in lubricating oil liquid. Background technique [0002] When monitoring the operating status of mechanical devices, the analytical ferrgraph can obtain the wear information of the machine. According to the analysis of the abrasive particles in the oil, it can evaluate the working condition of the machine and perform early prediction and early warning. According to the size, shape, and Observation of color, surface texture, etc., to determine worn parts, fault location, wear type and other information. Therefore, by monitoring the condition of abrasive particles in the lubrication system through the analytical ferrography instrument, early failure symptoms can be found in time, and corresponding measures can be taken to prevent major accidents. At present, the monitoring of mechanical devi...
