The selection of tensioning device should give priority to fixed tensioning devices for short distances and small transportation volumes, and also for medium-length conveyors. Fixed winch tensioning device and heavy hammer tensioning device can be selected. For long-distance belt conveyors, weight tensioning devices should also be preferred when there is sufficient space. To reduce the space occupied by the equipment, consider applying an automatic tensioning device. For particularly long conveyors, you can consider installing a tensioning device on the conveyor, a fixed tensioning device and a weight tensioning device, or a fixed tensioning device and an automatic tensioning device.
The selection and calculation of the tensioning device is mainly the calculation of the tensioning force and the tensioning stroke. When selecting the automatic tensioning device, the power of the automatic tensioning drive device must also be calculated. The design calculation of the tensioning device needs to be carried out for different tensioning devices.
Fixed tensioning device Since the stroke of the conveyor cannot be adjusted once the conveyor starts, it must be fully tightened before the conveyor starts. Use the conveyor belt tension before startup and the tension after startup. The tensioning force is determined by the equal relationship between the tight extensions. Of course, the tightening stroke of the tensioning device should be guaranteed.
The weight tensioning device should provide the maximum tensioning force required by the equipment and ensure the maximum tensioning stroke of the conveyor belt.
For the automatic tensioning device, the tensioning force required by the conveyor under different working conditions should be calculated. Although the winch used in the tensioning device does not require a large space, it is necessary to leave necessary travel for the tensioning trolley.
