The transmission force of the belt conveyor comes from the conflict between the belt and the transmission drum. If the conflict force is too small, belt slippage may occur. Therefore, the tension of the belt conveyor belt directly affects whether it can run stably. The belt conveyor will inevitably encounter various resistances during the operation. Generally, according to the nature of resistance, it can be divided into uniform resistance and gathering resistance.
The uniform distribution resistance mainly includes: deformation resistance of the conveyer belt, crush resistance of the conveyer belt on the idler roller, and resistance during the idler roller operation. The gathering resistance mainly includes: the resistance of the redirecting drum, the unloading resistance of the conveyor belt, the resistance of the loading point, the resistance of the cleaner, etc. The importance of the belt conveyor tensioning equipment in the belt conveyor operating system, Zhang The importance of compact equipment is mainly reflected in the following aspects.
Make the separation point of the conveyor belt and the tumbling roller have proper tension and conflict force to avoid belt slipping. The traction of the belt conveyor comes from the conflict between the belt and the transmission roller, and the difference in tension between the meeting point and the separation point. If there is a lack of tension at the separation point, the conflict between the belt and the roller becomes smaller, and the belt conveyor will run without the belt, and the belt will slip at the separation point.
Therefore, in order to make the belt run stably, the tensioning device ensures that a sufficient tension is provided at the separation point, and then the belt conveyor is provided with the conflicting force required for stable operation. This requires the tensioning device to make the belt on the belt suitable for Of tension. Excessive sag of the belt between the rollers will lead to the phenomenon of material deviation, belt deviation and increased running resistance.
