Embodiment 1

[0038] After detecting and analyzing the ferrogram of hydraulic oil of a rocker arm equipment, the test results show that the concentration of fatigue peeling and layered wear particles is 15%, and the size of wear particles is greater than 50 μm.

[0039] Therefore, the wear condition of the rocker arm equipment is serious and needs to be dismantled and inspected. After dismantling and inspection, it was found that the bearing was seriously damaged, the cage was damaged, the balls were scattered, and the gears were partially toothed. Through this inspection, the expansion of the accident was successfully prevented.

Embodiment 2

[0041] After detecting and analyzing the ferrogram of the hydraulic oil of a piece of equipment, the test results show that the concentration of sliding wear particles is 25%, and the size of the wear particles is 40 μm. As a result, the equipment was in a severe state of wear and required dismantling for inspection.

Embodiment 3

[0043] After detecting and analyzing the ferrogram of the hydraulic oil of a piece of equipment, the test results show that the concentration of black oxide is 55%, and the size of wear particles is 100 μm. As a result, the equipment was in a severe state of wear and required dismantling for inspection.

Abstract

The invention discloses an equipment quality control method for employing a rotary ferrograph, which comprises the steps as follows: the particle concentration and particle sizes of normal wear particles in oil is detected by the rotary ferrograph; the particle concentration and the particle size of a first abnormal particles are detected by the rotary ferrograph; the particle concentration and the particle size of a second abnormal particles are detected by the rotary ferrograph; when the numerical values of the normal wear particles, the first abnormal particles and the second abnormal particles are detected to be within a preset numerical value scope, corresponding detection or maintenance operation is actuated. Compared with the prior art, the equipment oil control method is adopted for converting electromechanical maintenance from traditional breakdown maintenance and periodic maintenance into the mode of monitoring the equipment state in advance so as to realize preventive and predictive overhauling on the equipment.

Description

technical field [0001] The invention relates to an equipment quality control method using a rotary ferrography instrument. Background technique [0002] In the traditional maintenance method of coal mine equipment, parts replacement and component repair can only be carried out after equipment problems occur. This method can only play the role of after-the-fact remedy. For many major accidents, once they happen, it will lead to unpredictable economic losses. [0003] Therefore, it is necessary to design a new method so that the problems existing in the equipment can be found in time before the coal mine equipment breaks down, and corresponding measures can be taken to prevent them. Contents of the invention [0004] Aiming at the defects of the prior art, the object of the present invention is to provide an equipment quality control method capable of timely discovering the tendency of oil deterioration in the equipment and taking control measures in time. [0005] The equ...
