Belt conveyor belts common faults



 
A belt conveyor belt deviation runtime is the most common faults. To address such failures is important to note the dimensional accuracy of installation and daily maintenance.

There are several reasons for deviation, to be based on the difference between handling different reasons.
1 Adjust the belt conveyor idlers bearing belt in the middle of the entire belt conveyor idlers deviation, adjust the position to adjust the deviation; idlers in the manufacture

of both sides of the mounting holes are worked into holes for be adjusted. Specific adjustment method (see Figure 1), the specific method is biased belt which side roller group belt conveyor manufacturer

which side forward toward the belt forward direction, or the other side after the shift.
2 Install aligning roller group aligning roller group has many types such as an intermediate shaft type, four-link, vertical roller type, etc. The principle is the use of block

or roller rotates in the direction in the horizontal plane lateral thrust block or generate the Automatic belt adjustment belt deviation reaches to the heart of the purpose.

Average total length of the belt conveyor or belt conveyor shorter run time using this method bidirectional more reasonable, because the shorter belt conveyors easier deviation

and not easy to adjust. And long belt conveyor is best not to use this method, because self-aligning roller group life belt use would have some impact.Incline Belt conveyor
3 Adjust the drive pulley and the driven pulley and bend pulley position adjustment bend pulley belt deviation adjustment is an important part. Because a belt conveyor with at

least two to five rollers, all the rollers must be perpendicular to the installation location of the longitudinal direction of the belt conveyor centerline, if the skew is too

large deviation inevitable. Adjustment Method and its group of similar idlers. For the head drum as the drum belt deviation to the right, the right of the bearing should be

moved forward, the belt deviation to the left of the drum, the left bearing housing should be moved forward, also the corresponding After moving the left or right side bearing

housings after the shift. Rear roller adjustment method and the head drum opposite. Adjustment method (see Figure 2). After repeated adjustments until the belt transferred to an

ideal location. Adjust the drive or bend pulley in the best pre-install its exact location.
4 tension belt tension adjustment at the adjustment at the conveyor belt deviation adjustment a very important part. Hammer at the upper two tensioning idler pulley in addition

to other than perpendicular to the longitudinal direction of the belt should be perpendicular to the vertical line of gravity, which is to ensure its axis horizontal centerline.

Tensioning screw or hydraulic cylinders with tension, the tension of the two roller bearing shall simultaneously pan, to ensure the longitudinal direction of the drum axis and

perpendicular to the belt. Specific method of adjusting the belt deviation adjustment of the drum at similar.
