Deviation of belt conveyor and processing method of fault interpretation       

There are many reasons for the deviation of the belt, need different processing according to the different reasons. Below small detailed analysis of causes and solutions of conveyor belt deviation.

Belt deviation is the most common fault in the operation of belt conveyor. To solve this kind of fault, the key is to pay attention to the installation of dimensional accuracy and routine maintenance.

Adjust the carrying roller group

When the belt of the belt conveyer deviates from the middle part of the belt conveyer, the position of the roller group can be adjusted to adjust the deviation; at the time of manufacture, both sides of the roller group are processed with growth holes for adjustment.

Two. Install self-aligning roller set

Self-aligning roller group has many kinds of types such as the intermediate shaft, four connecting rod type, vertical roller type, generally in the two-way operation of the total length of belt conveyor belt conveyor is short or when using this method is more reasonable, the reason is short of conveyer belt deviation more easily and not easy to adjust. And long belt conveyor is best not to use this method, because the use of self-aligning roller group will have a certain impact on the service life of the belt.

Three, the adjustment of the driving drum and the drum to the position

The driving drum and the drum to the adjustment is an important link of belt deviation adjustment. Because a belt conveyor has at least 2 to 5 rollers, the installation position of all rollers must be perpendicular to the center line of the belt conveyor length direction, if the deviation is too large, there must be deviation. The adjustment method is similar to the adjustment of idlers.

Four, the adjustment of tension

The belt tension adjustment is a very important part of belt conveyor deviation adjustment. The two modified rollers at the top of the heavy hammer should be perpendicular to the gravity perpendicular to the direction of the belt length, that is to say, to ensure the centerline level of the shaft. When the screw tensioner or hydraulic cylinder is tightened, the two bearing seats of the tensioning drum should be shifted simultaneously to ensure the vertical axis of the roller and the longitudinal direction of the belt.

Five, at the transfer point on effect of feeding position on the belt deviation

The location of material dropping at the transshipment point has a great influence on the deviation of the belt, especially when the two belt conveyor is perpendicular to the horizontal projection. Generally, the relative height of the two belt conveyors at the top and bottom of the transshipment point should be considered, and the relative height is too low or too high, so the materials are difficult to center. In the design process should be as much as possible to increase the relative height of the two belt machine.

Only grasp the principle of the occurrence of the fault, understand the cause, in order to timely respond to the correct response to ensure the smooth progress of construction.
