Detailed Problem Analysis and Solutions

1. High Noise

    Possible Causes: Bearing damage, insufficient lubrication, or roller misalignment.

    Solutions: Regularly inspect and replace damaged bearings, ensure adequate lubrication, and correct misaligned rollers.

2. Inefficient Operation

    Possible Causes: Bearing seizure, deformed roller shaft, or dirt accumulation.

    Solutions: Clean or replace seized bearings, replace deformed roller shafts, and keep roller surfaces clean.

3. Severe Wear

    Possible Causes: Inappropriate roller material for the work environment, harsh external conditions.

    Solutions: Choose more wearresistant roller materials, such as ceramic rollers, and improve the harsh working conditions.

4. Belt Misalignment

    Possible Causes: Improper roller installation, incorrect positioning.

    Solutions: Adjust the roller installation position, ensure all rollers are parallelly aligned to prevent belt misalignment.

5. Bearing Overheating

    Possible Causes: Insufficient lubrication, excessive bearing load.

    Solutions: Regularly lubricate bearings, check and reduce the load on bearings to ensure they operate at normal temperatures.

6. Frequent Roller Damage

    Possible Causes: Poor material quality, harsh usage environment.

    Solutions: Choose highquality rollers suitable for harsh environments and improve the usage conditions on site.

7. Uneven Roller Speed

    Possible Causes: Bearing damage, roller wear.

    Solutions: Replace damaged bearings and worn rollers to ensure normal roller operation.

8. Poor Dustproof Performance

    Possible Causes: Seal structure failure, high dust environment.

    Solutions: Inspect and replace seal devices, regularly clean the rollers and surrounding environment to prevent dust ingress.

9. Belt Slippage

    Possible Causes: Smooth roller surface, insufficient belt tension.

    Solutions: Add antislip designs to the roller surface, adjust the belt tension to prevent slippage.

10. Foreign Object Jamming

     Possible Causes: Large gaps between rollers, high impurity content in conveyed materials.

     Solutions: Adjust roller spacing to minimize gaps, remove impurities from materials before conveying.
