Abstract:
The paper analyzes two typical failure forms of roller and conveyor at the belt conveyor, and describes the maintenance methods of prevention and elimination failures to ensure the normal operation of belt conveyor.
1. Introduction:
Belt conveyor is monly used equipment of continuous transport, it has a high efficiency and large conveying capacity, simpler construction, small amount of maintenance. Can be achieved at different distances, different materials transportation. It iss widely used in mining, coal handling system in thermal power plant and other projects. Belt conveyor will often occur some typical problems in the course, this paper Based on mon typical failure of belt conveyor during use, analysis the cause of failure, proposed some effective methods to solve the problem.
2. Typical faults of conveyor belt:
. Conveyor belt deviation
In the belt conveyor, as the conveyor belt is ponents, transmit power and motion, also is ponents, support material load. Working plex, so at work often happen belt deviation. Deviation is the conveyor belt during operation, the center line of belt deviation the center line of conveyor. As the conveyor belt deviation may cause between the belt edge and rack wear, cause belt edge premature damage, Ranging impact the life of conveyors, affect the throughput of materials, Weight is caused by withdrawal material, even happen stop occurrence, direct impact on production. As the conveyor belt is more important, the most expensive parts. Its price about 25%~50% to the conveyor. So analysis the reasons of belt deviation, reduce and eliminate belt deviation, It is an important part of ensure belt to work, extend equipment life. Cause the belt occurs deviation because of the following factors.
. In the device itse
