Problems solved by technology

The detection method of connecting the circuit through the grinding debris will also fail to connect the circuit due to the small size of the grinding debris, or because the iron filings do not fall between the magnetic steel and the metal sheet during the adsorption process, resulting in the circuit being unable to connect, and thus missing detection.

Abstract

The invention relates to the technical field of engineering machinery, and discloses a detection device for detecting abrasive dust in oil and engineering machinery. The detection device comprises the following modules of: a first magnetic field generation module for generating a first magnetic field under the action of a second magnetic field and adsorbing the abrasive dust in the oil flowing through the first magnetic field; an induced electromotive force generation module of which the whole or part is located in the first magnetic field, wherein the induced electromotive force generation module is used for generating induced electromotive force; and an induced electromotive force monitoring module which is connected with the induced electromotive force generation module and used for monitoring whether induced electromotive force is generated in the induced electromotive force generation module or not so as to detect whether abrasive dust exists in the oil or not, wherein the induced electromotive force is generated on the basis that the first magnetic field generation module adsorbs the abrasive dust existing in the oil flowing through the first magnetic field through the first magnetic field. Therefore, the situation that a circuit cannot be connected due to the fact that the size of the abrasive dust is small or the falling point of the abrasive dust is not located between circuit connecting points is avoided, and the probability of missed detection is reduced.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a detection device for detecting wear debris in oil liquid and construction machinery. Background technique [0002] The boom rotation mechanism is a hydraulic direct drive mechanism, which converts the translation of the piston in the mechanism into the axial rotation of the boom through hydraulic drive. Due to the long-term operation of the boom rotation mechanism under complex working conditions such as heavy loads, the continuous meshing between the gears leads to surface wear, especially when the rotation mechanism repeatedly starts and stops, shock vibration occurs, which aggravates the wear between the gears. Long-term wear and tear will make the gear fit gap in the mechanism larger, making it unable to move smoothly, and eventually causing the structure to be scrapped. How to detect the wear of the gear teeth during the use of the rotating mechanism, espec...
