The Risks of Conveyor Belt Running Deviation

The belt running deviation is rather harmful during the operation. According to the actual operation of belt conveyor, the deviation effects on the operation and production of belt conveyors are mainly in the following aspects:
1. Failure breakdown emergency stop device
The failure breakdown emergency stop device with protective purposes is installed on the belt conveyor. When the belt deviation occur and near the failure breakdown emergency stop device, it will causes the device to stop the machine immediately, and hence causes the conveying process to stop. This will affect the efficiency of production line, and hence increase the cost of production. Some serious cases might lead the project unable to finish on time, or even causes the undesirable contract disputes.

2. Reduce the life-span of main components
Firstly, the breakdown of roller, bearings and other mechanical components, such as belt running deviates frompulley will cause the increasing of the force of roller, and hence it will increase the probability of failure. Secondly, it leads the belt to be worn out in a shorter period. The belt running deviation cause the materials spread onto the return belt. It will cause the belt and roller encapsulate to wear and tear abnormally as the materials can’t be fully removed from the return belt. Thus, the life-span of belt and roller will be shorten. Thirdly, it leads the tear and wear from the edge of belt, if the edge of belt collides with frame for a long time during the operation, it will cause the severe wear of belt edge and thus affects the life-span of belt which will leads to the increase of maintenance cost and also the operation cost. When the serious belt deviation occurs, it causes belt tearing directly. Belt deviation might lead to serious overturning of belt, causing the increasing of unilateral force ,hence it will lead to belt transverse fracture.
