widely used, can be roughly divided into: large dip Angle belt conveyor, fixed belt conveyor, mobile belt conveyor. Various accidents will occur in the use of belt conveyor. Our company summarizes the following common failure causes, hoping to help users reduce the incidence of failure and avoid production loss.
1, belt conveyor slip
The reasons are: belt conveyor path overload, belt tension is insufficient, friction coefficient does not match the design value and the actual value of the belt between the driving roller.
Prevention and control measures: take anti-watering measures, control the feeding amount, prohibit overload operation, adjust the tension roller, increase the belt tension. When the belt is depressed, some of the material on the belt is removed and then driven to increase the friction coefficient of the driving roller.
2, belt conveyor leakage and spreading
a. Materials at transfer point
It is mainly in the hopper, guide groove and other places, such as the belt conveyor is seriously overloaded, the rubber skirt of the belt conveyor baffle is damaged, the steel plate design at the guide groove is far away from the belt, and the rubber skirt often makes the material out of the guide slot.
This situation can increase transport capacity to maintain control.
b. Materials for suspension of concave belt
Belt Segments When the concave segment has a small radius of curvature, the belt hangs in the air. At this point, the belt is slotted and the belt leaves the slotted roller set, making the Angle of the belt groove smaller and some materials overflow.
Therefore, in order to avoid this situation, a large concave radius of curvature is used in the design and installation of belt conveyors.
c. Deviation in materials
When the belt conveyor deflects, the height of the two sides changes with the operation of the conveyor belt, so when the material changes, the side of the material is higher, the other side is lower, and the material is scattered from the bottom.
Treatment method: Adjust the belt deviation.
