First, because the processing, assembly and debugging of new equipment parts wear too fast, in the process of operation, the surface of the concave and convex parts of the parts will appear the phenomenon of friction, that is, abrasive then will cause the surface of the parts to wear.

Two, when the understanding of the structure and performance of the equipment motor is not enough, it will easily lead to mistakes, then it is inevitable that there will be failure.

Three, the lubrication is not done well, the gap between the new equipment parts is relatively small, the lubricating oil is not easy to form an oil film, then it will reduce the lubrication efficiency, leading to early abnormal wear of the equipment.

Four, when it is found that the equipment is loose, it is likely to be because of the phenomenon of deviation, and the exhaust in use will be affected by the impact and vibration and other alternating loads.
