Analysis and treatment of abnormal noise and belt slip of trough belt conveyor

Due to the noise caused by the deviation of the roller from the middle: during the operation of the belt conveyor, the roller is a device prone to noise, and will be accompanied by periodic vibration. On the one hand, the noise is due to the uneven thickness of the seamless steel pipe wall in the process of manufacturing the roller, so that the roller has a relatively large centrifugal force. On the other hand, the middle of the bearing holes at both ends and the center of the outer circle have a large deviation in the process of processing the roller, which will also produce a relatively large centrifugal force, resulting in abnormal noise. To deal with the problem of abnormal noise, first check the bearing of the belt conveyor, if the bearing is damaged, the bearing should be replaced, if the bearing is not damaged, then take other ways to deal with it.

For the shaft of the coupling caused by different noise problems, the position of the motor reducer can be adjusted accordingly to solve.

For the abnormal noise problems brought by the drum, it is generally caused by the damage of the bearing, so the replacement of the bearing can be done.

For the belt slip phenomenon, if it is the hammer tension belt machine slip. You can add counterweight until the belt does not slip, but it needs to be noted that the addition can not be too much so as to avoid too much tension but affect the service life of the belt. If it is spiral tensioning or hydraulic tensioning belt machine slip problem. The tension force of the belt can be increased by adjusting the tension stroke. It should be noted that this treatment method may cause deformation of the belt. When this problem occurs, the deformed belt can be cut off for subsequent operations.
