An oil wear particle analyzer

Abstract

The invention relates to an oil abrasive particle analyzer, comprising a first housing, a peristaltic pump, a pinch valve and a detection unit, the peristaltic pump, the pinch valve and the detection unit are all located inside the first housing, wherein the The detection unit is fixed on the inner surface of the first housing, and the detection unit is used to collect data on the characteristics of abrasive particles in the oil; the peristaltic pump is located on the side of the detection unit, and the peristaltic pump is connected to the first housing Fixedly connected, the peristaltic pump is used to alternately squeeze and release the fluid in the pipeline to pump the fluid; the pinch valve is located on the side of the peristaltic pump, and the pinch valve is fixedly connected to the inner surface of the first housing , the pinch valve is used to control the on-off of the pipeline. The device integrates the control element, peristaltic pump, valve and detection unit, and through the structural layout, the components are tightly connected, which reduces the existing detection equipment. The volume of the wear particle detection equipment is miniaturized and integrated, and the wear particle detection of dark oil samples is realized.

Description

technical field [0001] The invention belongs to the field of equipment wear state monitoring and relates to an oil abrasive particle analyzer. Background technique [0002] Friction loss between parts in mechanical equipment is inevitable. Abrasive particles and some foreign pollutants generated during mechanical operation will lead to deterioration of the lubrication state of the friction pair, which will cause wear and tear, and eventually cause equipment failure or damage. In order to monitor the internal wear of the machine in a timely manner, the ferrographic analysis method is often used on site to analyze the abrasive particles contained in the oil inside the machine. By obtaining the shape and quantity information of the abrasive particles, the wear status of the internal parts of the machine can be known in time. Generally, the particle size of abrasive particles that cause wear ranges from a few microns to hundreds of microns. Generally, it is very difficult to det...

AI Technical Summary

Problems solved by technology

The analyzer can effectively carry out the online intelligent detection of ferrographic analysis. Although the analyzer has cleaned the abrasive particles, on the one hand, the detection and cleaning in this device need to be carried out in different mechanisms, and the equipment is relatively large. On the one hand, after cleaning, there are residual liquid droplets between the abrasive grains and the spectrogram, which will affect the detection results, and the accuracy is low. If the cleaning agent is completely volatilized, it will take a long time and the detection efficiency of the equipment will be low.
