When the PVC conveyor belt is in normal operation, the belt speed is not less than 95% of the roller speed, and the conveyor belt is prone to slipping. PVC conveyor belt slipping is also a production failure that is often encountered in production, so how to avoid conveyor belt slippage?
1. The initial tension of PVC conveyor belt is too small. Insufficient tension at the conveyor belt leaving the roller causes the conveyor belt to slip. This situation usually occurs at startup. The preventive method is to adjust the tensioning device to increase the initial tension.
2. The friction between the drive roller and the conveyor belt is not enough to cause slipping. The reason for the rejection is mostly water on the PVC conveyor belt or humid environment. The prevention method is to add some rosin powder on the drum. But be careful not to throw in by hand, and use blowing equipment to blow in to avoid personal accidents.
3. The tail roller bearing is damaged and does not rotate or the upper and lower roller bearings are damaged too much. The cause of the damage is that the tail floats too much, and the damaged or inflexible parts are not repaired and replaced in time, which increases the resistance and causes skidding.
4. Too fast starting speed can also cause slippage. At this time, it can be started at a slow speed. If the squirrel cage motor is used, it can be started after two jogs, which can also effectively overcome the slipping phenomenon.
5. If the load of PVC conveyor belt is too large, it will slip if it exceeds the capacity of the motor. The advantage of slip at this time is to protect the motor. Otherwise, the motor will be burnt after a long time. But for operation, it is a slip accident.
