How to reduce the deviation of belt conveyor
2019-04-17
Belt conveyor is the conveying equipment in fertilizer production line. It plays an important role in fertilizer, metallurgy, coal, mining and other industries. Belt deviation is the main possible failure of belt conveyor. Belt deviation will increase the resistance of belt running and increase the wear between the belt and frame. We should pay attention to the running condition of the conveyor during production, and find the cause that may cause the belt to run off, so as to prevent accidents from happening, reduce conveyor failures and improve the efficiency of production.
Possible Failure of Belt Conveyor
1.The belt of the conveyor is worn. After a period of use, a well-running belt will irreversibly change the belt tension, which will reduce the tension of the belt and cause the belt relaxation. So the belt edge will appear different degrees of wear and tear, and then lead to belt deviation. Therefore, in regular maintenance, pay attention to adjust the belt state.
2. The drum and idler of belt conveyor are sticky with foreign bodies. The drum and idler that support the belt bind to other things, resulting in uneven tension on both sides of the belt, causing the belt run off. Therefore, it is necessary to keep the production equipment clean to avoid foreign bodies affecting the operation of the equipment.
2.Vibration of belt conveyor during operation. The mechanical vibration of belt conveyor is unavoidable when it is running. The faster the belt runs, the greater the vibration, and the greater the deviation of the belt.
4. For short-line belt, if the belt deviates, it is mainly rectified by adjusting the drum; for long-line belt, the deviation generally only exists on the local belt line, so the deviation can be rectified by adjusting the roller rack near the deviated belt line. Whether the conveyor loads materials or not has different operation status. After no-load rectification, the conveyor does not necessarily run away when loading, so we have to carry out experiments under both no-load and loading conditions.
