Common faults and treatment methods of belt conveyor

Question

Accepted Answer

First, the belt conveyor belt does not rotate. After the motor starts, the idling belt of the drive drum slips and the belt can not start. This kind of failure is caused by the insufficient belt tension, the tension device is not adjusted well, the belt is too long, heavy load start, and the tail of the belt is piled up with coal.

Second, belt conveyor belt deviation. The reason for deviation is that the belt has lateral force in operation, and the reasons for the lateral force are as follows: the conveyor is loaded on one side, not installed in the center position; The installation axis of the idler and roller is not vertical to the center of the conveyor belt; The height of the steel wire rope of the fuselage is inconsistent; The connection of conveyor belt is not correct and straight; The position of the coal unloading drum is not adjusted well; The tail drum and guide roller can cause belt deviation if they are not adjusted well.

Third, the belt conveyor belt is easy to be disconnected. This is caused by the belt tension is too large, the joint is not firm, the quality of the buckle is poor, the belt is used too long, the maintenance quality is poor, etc. the method is to tighten the tension device, reduce the tension and replace the new belt in time, and strengthen the maintenance quality.

Fourth, the sound of the belt conveyor reducer is abnormal. This is caused by excessive wear clearance of bearings and gears or loose screw of housing. The treatment method is to replace bearings, adjust clearance or replace integral reducer for overhaul.
