I. The Hazards of Insufficient Tension
1. Frequent Slippage and Loss of Drive: Insufficient friction between the conveyor belt and the rollers makes the belt prone to slipping and idling when conveying loads; this directly reduces conveying efficiency and may even prevent the proper feeding of materials.
2. Increased Misalignment and Wear: Uneven tension or overall slackness causes the conveyor belt to frequently drift off-center. Over time, this edge friction leads to fraying and tearing of the belt edges, significantly shortening its service life.
3. Vibration and Material Spillage: A slack conveyor belt exhibits excessive vibration during operation. When conveying materials on an incline, this makes it easy for materials to spill off the belt, thereby increasing the workload for cleanup and resulting in material loss.
4. Accelerated Joint Fatigue: Slackness subjects the belt joints to repetitive stress and pulling forces, making them prone to premature delamination and cracking, which can ultimately lead to catastrophic joint failure.
II. The Hazards of Excessive Tension
1. Accelerated Aging and Wear of the Belt Body: Prolonged, excessive tension causes irreversible stretching and deformation of the belt body. This leads to premature thinning, hardening, and cracking, reducing the belt's service life by more than 30%.
2. Increased Equipment Load: Excessive tension increases operational resistance, causing the motor's current to rise. This leads to overheating due to overload-potentially even burning out the motor-while simultaneously accelerating the wear and premature failure of rollers and bearings.
3. Increased Risk of Belt Rupture: Excessive tension subjects the belt's core to sustained, excessive tensile forces. This makes the core fibers prone to fracturing, which can lead to sudden, catastrophic tearing of the entire belt during operation, potentially triggering serious industrial safety accidents.
4. Increased Energy Consumption: The additional resistance caused by excessive tension increases the equipment's overall power consumption, thereby raising energy costs over the long term.
