1. Appearance inspection
Wear:
Check the surface of the conveyor belt for obvious signs of wear, aging, deformation or damage, especially at the edges and joints.
If the wear depth of the conveyor belt surface exceeds 50% of the thickness of the cover rubber, or is worn to expose the steel rope core or nylon core, it means that it needs to be repaired or replaced.
Tears and damage:
Check the conveyor belt for tears, scratches or damage. Small tears or scratches can be repaired by patching, but if the damage is serious, it may need to be replaced.
Material accumulation:
Check the surface of the conveyor belt for material accumulation or residue, which may cause the conveyor belt to slip or damage.
2. Operation status inspection
Slip phenomenon:
Observe whether the conveyor belt slips during operation. Slipping may be caused by insufficient tension of the conveyor belt or surface wear.
Deviation phenomenon:
Check whether the conveyor belt deviates. Deviation may be caused by uneven tension of the conveyor belt, incorrect position of the rollers or uneven wear of the conveyor belt.
Abnormal vibration:
Check whether the conveyor belt has abnormal vibration or noise during operation. These may be signs of wear or damage to the conveyor belt.
3. Performance inspection
Tension check:
Use the deflection method or the tensiometer method to check the tension of the conveyor belt and ensure that it is within a reasonable range. If the tension is insufficient or too tight, the tensioner needs to be adjusted.
Roller and drum inspection:
Check whether the rollers and drums rotate flexibly and whether there are signs of jamming or damage. Wear or damage to the rollers and drums will affect the operating state of the conveyor belt.
Drive device inspection:
Check the operating state of the motor, reducer and drive roller to ensure that there is no abnormal noise or vibration. Failure of the drive device may cause the conveyor belt to slip or be damaged.
4. Wear degree assessment
Local wear:
If the conveyor belt has local wear in some parts (such as the drop point, joint), but the overall wear is not serious, it can be repaired by local repair.
Overall wear:
If the overall wear of the conveyor belt is relatively uniform, but the wear depth is deep, it may be necessary to consider replacement.
5. Economic Assessment
Repair Cost:
Evaluate the cost of repair versus replacement. If the cost of repair is too high or the belt cannot be repaired, replacing the belt with a new one may be a more economical choice.
Repair Frequency:
If the belt frequently needs repair, it may be old and needs to be replaced.
6. Safety Assessment
Safety Hazards:
If damage to the belt could cause material leakage, slips, or other safety hazards, repair or replace it immediately.
7. Maintenance Records
Historical Records:
Check the maintenance records of the belt to understand its historical wear and maintenance frequency. If the belt is nearing its expected service life and is noticeably worn, consider replacing it.
