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
