Abstract

The invention relates to an oil pollutant multi-parameter integrated detecting device and method based on the phase shifting technology. In the prior art, unknown oil pollutants cannot be distinguished or detected, only one or two known oil pollutants can be distinguished and detected, and the actual detection and application requirements cannot be met. The inductance detection and capacitance detection can be conducted on each known oil pollutant at the same time, an inductance output curve corresponding to inductance output signals and a capacitance output curve corresponding to capacitanceoutput signals of each pollutant are obtained, and the known oil pollutants can be distinguished, detected and counted by comprehensively analyzing the inductance output curves and the capacitance output curves of the pollutants. An inductance detection object and a capacitance detection object are the same, and the inductance detection and capacitance detection can be conducted at the same time without time difference. The oil pollutant detection cost is reduced, the detecting device is simple, the detecting result is reliable, and the actual detection and application requirements are met.

Description

technical field

[0001] The invention relates to the field of inductance detection of oil pollutants, to the field of capacitive detection of oil pollutants, to the field of signal processing of oil pollutant detection, and in particular to a multi-parameter integrated detection device for oil pollutants based on phase-shifting technology and method. Background technique

[0002] Hydraulic oil is an important working fluid of the hydraulic system, and the quality of the oil is directly related to the working state of the hydraulic system. On-line detection of main pollutants in hydraulic oil can realize fault prevention and diagnosis of mechanical equipment, thereby prolonging the life of mechanical equipment and saving economic costs. The pollutants in the hydraulic oil mainly come from the residual impurities in the manufacturing process of the hydraulic system, the pollutants generated by the friction of the components during the operation of the system, and the external ...
