Problems solved by technology

Since grease is a solid or semi-solid substance with high viscosity and metal particles wrapped in grease, detection is difficult and costly. Traditional methods use solvents to dissolve grease, but different solvents have different deviations in the analysis results. low precision
At the same time, this detection method will also cause pollution to the oil.

Abstract

The invention provides a lubricating grease pollutant detection device and method. The device comprises a lubricating grease heating and liquefying module and an oil liquid detection chip, the lubricating grease heating and liquefying module comprises a lubricating grease inlet, a resistance wire heating device and a first metal pipe; the lubricating grease inlet is connected with the resistance wire heating device, and the lubricating grease inlet and the resistance wire heating device are both arranged in the first metal pipe and wrapped by the first metal pipe; lubricating grease is heated by the resistance wire heating device through the lubricating grease inlet, so that solid lubricating grease is liquefied; the oil detection chip comprises an oil inlet, a micro-channel, a detection unit and an oil storage tank; the oil inlet is formed below the resistance wire heating device, the detection unit is connected with the oil inlet through a micro-channel, the oil storage tank is connected to the tail end of the micro-channel, a liquefied lubricating grease sample is conveyed to the detection unit through the oil inlet, and the detection unit detects metal particles and moisture in the oil sample; and the detected oil sample flows into the oil storage tank through the micro-channel.

Description

technical field [0001] The invention relates to the technical field of grease detection in mechanical equipment, in particular, to a grease contaminant detection device and a detection method thereof. Background technique [0002] In various mechanical equipment, grease lubrication is used in many friction pairs. For example: the meshing parts of the fan ring gear, some lubrication points of mechanical equipment, bearings of various machinery and equipment, etc. Grease pollutants mainly include metal particles and water. Metal particles will cause abrasive wear, metal crushing and scratching, and metal fatigue. Water will destroy the lubrication effect, deteriorate the grease, cause equipment wear, and cause metal rust. Metal particles and water in grease can seriously damage the performance of machinery and equipment, and are one of the most common failure forms that lead to abnormal operation and failure of various machinery and equipment. The metal particles in the grea...
