Abstract

The invention provides a planar inductance coil type hydraulic oil grain graded monitoring device. The device comprises a detection pipeline, connection structures arranged on the two sides of the detection pipeline and used to connect the monitoring device to bypass pipelines, and a plurality of graded detection modules arranged on the detection pipeline, wherein the graded detection modules comprise a coarse filter element inductance detection area in the direction of a liquid to be detected flowing into the detection pipeline, and a fine filter element inductance detection area in the direction of the liquid to be detected flowing out of the detection pipeline. The device provided by the invention has the advantages that filter elements with different meshes are added into the detection pipeline to effectively absorb metal grains in hydraulic oil, so that the metal grains can be detected, the grains with difference sizes can be effectively separated from the hydraulic oil, grain size information can be acquired, and the grain content in the hydraulic oil can be reduced; and two planar inductance coils which are parallelly connected and oppositely arranged according to the design of the device achieve higher detection sensitivity.

Description

technical field [0001] The invention relates to the technical field of G01 measurement and testing, in particular to a planar inductance coil type hydraulic oil abrasive particle classification monitoring device. Background technique [0002] The failure of the hydraulic system is caused by the contamination of the hydraulic oil. The abrasive particles in the hydraulic oil will circulate in the hydraulic system with the hydraulic oil, which will increase the wear of the hydraulic components, reduce their life, and lead to failures. For this reason, the hydraulic system is often equipped with an oil pollutant separation device. However, most of the existing abrasive particle detection devices are only used for off-line detection in the laboratory, and the online monitoring devices installed in the hydraulic system often only realize the monitoring of the overall concentration of abrasive particles, and cannot detect abrasive particles of different sizes. Enables more detail...
