Problems solved by technology

[0002] The failure of the hydraulic system is caused by the pollution of the hydraulic oil. The pollutants in the hydraulic oil mainly come from the residual and generated pollutants in the hydraulic system and the pollutants intruded from the outside. The pollutants are mainly solid particles, water and air bubbles; for the oil The detection of pollutants in oil can not only accurately evaluate the operating status of the hydraulic system, but also diagnose system faults according to the nature of the pollutants; the methods for measuring oil pollutants mainly include optical detection, acoustic detection, and inductance detection. And capacitive detection method, etc., but the types of pollutants that can be detected by each method are limited, and the detection of multiple pollutants in oil cannot be realized

Abstract

The invention relates to the technical field of oil system fault detection, in particular to an oil state monitoring device and a manufacturing method thereof. The oil state monitoring device comprises a substrate, a coil, an inductance excitation measurement module, an annular outer pole plate, a capacitance excitation measurement module, a fixture, a soft magnetic conducting rod and a data analysis system. The substrate is provided with a channel inlet, a channel outlet and a detection channel; the coil is arranged on the outer side of the detection channel, the inductance excitation measurement module is electrically connected with the coil, the annular outer pole plate is arranged on the outer side of the detection channel, the capacitance excitation measurement module is electrically connected with the annular outer pole plate, and the soft magnetic conducting rod is fixed on the substrate through a fixture. Through the coil, the inductance excitation measurement module, the annular outer pole plate and the capacitance excitation measurement module, an inductance and capacitance dual-detection mode is formed, metal abrasive particles, bubbles, water and other pollutants in oil can be detected, and the detection range is widened.
