What should be paid attention to when selecting the correct pulley for the telescopic conveyor?
What factors should be paid attention to when selecting the correct pulley for the telescopic conveyor Chinese supplier? The design of the telescopic belt conveyor usually involves the selection of the pulley. The main criterion for the selection of the telescopic conveyor pulley is the diameter. Selecting large diameter redirecting pulley is advantageous to belt conveyor. However, when the diameter of the pulley increases, the quality of the driving pulley, the reduction ratio of the reduction gear of the driving device, and the quality and size of the reducer need to be increased accordingly. SKE Machinery--China bulk material conveyor supplier recommends that users mainly consider the following factors when selecting the diameter of the pulley:
1.The bending stress of the belt when the conveyor belt goes around the pulley;
2, the frequency of the bending of the telescopic conveyor belt is related to the guide way, the number of bypass pulleys, the distance and speed;
3.The maximum or average specific pressure between the conveyor belt and the pulley surface;
4. The allowable strength utilization ratio of the conveyor belt, which is the percentage of the ratio of the maximum tension of the conveyor belt to the allowable tension of the belt;
5.The installation location and use conditions of the telescopic conveyor;
6. Pulley lagging and deformation
The principle of determining the diameter of the pulley is that when the tensile stress of the telescopic conveyor belt is large, the additional bending stress should be smaller; on the contrary, when the tensile stress is small, a slightly larger bending stress is allowed, Smaller pulley diameter can be selected.
