According to the hydraulic part abrasion detection device, abrasion detection of the hydraulic part is achieved in the mode that abrasive particles generated due to abrasion of the hydraulic part in the hydraulic pipeline are electrified and make contact with the detection electrode to generate micro-current, the real-time performance of the detection result is higher, and the detection precision and the detection efficiency are higher.

Description

technical field [0001] The invention relates to the technical field of wear detection, in particular to a hydraulic component wear detection device, a hydraulic system wear detection device and an operating machine. Background technique [0002] The wear of hydraulic parts in the hydraulic system not only affects its own working performance, but the abrasive particles produced by the wear enter the hydraulic oil, which will also make other parts with friction pairs wear more during the working process, and then the hydraulic system will fail due to severe wear. Therefore, it is particularly important to detect the wear state of hydraulic parts. [0003] At present, the wear fault of hydraulic parts is usually monitored by manual detection. However, it is difficult to quickly find the wear phenomenon of hydraulic parts through manual detection. The wear fault cannot be found until the hydraulic system is shut down due to excessive wear, resulting in insufficient time and accu...
