Embodiment Construction

[0015] Specific embodiments of the present invention are given below, and it should be understood that the scope of the present invention is not limited to the content of the embodiments.

[0016] From the above discussion, we already know that the occurrence of abnormal wear debris less than a certain amount cannot explain the problem. This is accidental and not universal, and the working conditions of the equipment are still within the normal range. However, with the increase in the number of one or several kinds of abnormal wear debris, the microscopic local abnormal wear that produces them is becoming more and more common, and the working conditions of the equipment gradually tend to be worse and accumulate to a certain extent. At this time, the abnormal wear debris The appearance of the device becomes inevitable, and we can draw the conclusion of equipment lubrication failure according to the current wear debris situation. However, when the size, quantity, and type of abn...

Abstract

The monitoring method includes: preparing standard criteria for determining operating condition of mechanical equipment, sampling, making spectra and determining operating condition of equipment. The method tests sampled lubricating oil of mechanical equipment regularly, analyzing indexes of physics and chemistry, analyzing microscopic ferromagnetic grinding dust quantificationally and in qualitative. Based on statistical result, standard criteria for operating condition of equipment are prepared. Whether operating condition of equipment is normal or not is determined by comparing the condition with standard criteria. If there is abnormity, corresponding inspection or repairing can be arranged in order to prevent paroxysmal failure, reducing chain reaction of damaging parts and loss of stopping operation.

Description

technical field [0001] The invention relates to a method for monitoring the working conditions of mechanical equipment, in particular to a method for monitoring the working conditions of coal mining equipment. Background technique [0002] The characteristics of coal mining equipment are low speed and heavy load. There are limitations in monitoring it with the currently commonly used working condition monitoring methods. It is difficult to install sensors, and the sensors are also required to be intrinsically safe or explosion-proof. While traditional ferrography analysis emphasizes the shape, size and color of each wear debris, which are important to explain the causes of wear debris, the wear of mechanical parts is a complex process, in the same friction, wear and Under lubrication conditions, the size of the generated wear debris is different. Finding one or two abnormal wear debris can only indicate that abnormal wear has occurred once, and it cannot be determined that ...
