Abstract

The invention discloses a method for improving the detection precision of oil metal abrasive particles and a detection device, which are used for detecting oil metal abrasive particles of a hydraulicsystem. The oil metal abrasive particle detection device (3) is installed on an oil pipeline (1) and connected to a detection instrument (2) through a lead (21), and oil needing to be detected flows through the oil metal abrasive particle detection device (3). The invention is characterized in that the oil metal abrasive particle detection device comprises a first oil metal abrasive particle detection sensor (32) and an ultrasonic stirring and scattering device (31), and the ultrasonic stirring and scattering device (31) is arranged at the front end of the first oil metal abrasive particle detection sensor (32) and used for scattering agglomerated metal abrasive particles in oil before the first oil metal abrasive particle detection sensor (32) detects the agglomerated metal abrasive particles. According to the invention, the power ultrasonic stirring device is additionally arranged in front of the detection sensor, small agglomerated particles possibly existing in oil flowing throughthe power ultrasonic stirring device are scattered, the oil is stirred more uniformly and comprehensively, and misjudgment caused by agglomeration of the small particles is avoided.

Description

technical field [0001] The invention relates to the technical field of electromagnetic non-destructive testing, in particular to a differential detection of metal abrasive particles in oil, and in particular to a method for improving the detection accuracy of metal abrasive particles in oil and a detection device thereof. Background technique [0002] Hydraulic systems are widely used in modern industry, aerospace, ships, etc., will be applied to precision hydraulic systems. The in-service maintenance of the hydraulic system is also a very important part to ensure its safe operation. The detection and monitoring of oil is a common method to evaluate the status of various machines and predict various faults. The detection of abrasive particles in oil is an indispensable method in modern industrial maintenance activities. It is to ensure the long-term effective and stable operation of the hydraulic system. The conventional detection method can reduce the accident rate and imp...
