A method for improving the detection accuracy of oil metal abrasive particles and its detection device

Abstract

The present invention relates to a method for improving the detection accuracy of oil-liquid metal abrasive particles and a detection device thereof, which are used for the detection of oil-liquid metal particles in a hydraulic system. The oil-liquid metal abrasive particle detection device (3) is installed in an oil-liquid pipeline (1). , connected to the detection instrument (2) through the lead wire (21), the oil to be detected flows through the oil metal abrasive particle detection device (3), characterized in that the oil metal abrasive particle detection device comprises a first oil metal abrasive particle detection device (3). A particle detection sensor (32) and an ultrasonic stirring and dispersing device (31), wherein the ultrasonic stirring and dispersing device (31) is arranged at the front end of the first oil liquid metal abrasive particle detection sensor (32), and is used for dispersing the first oil in the oil liquid. An oil metal abrasive particle detection sensor (32) detects the previous agglomerated metal abrasive particles. The invention adopts a power ultrasonic stirring device before the detection sensor to break up the small particles that may be agglomerated in the oil flowing through it, so as to achieve a more uniform and comprehensive agitation of the oil, so as not to cause errors due to small particles agglomeration sentence.
