The Repair Method Of Belt Conveyor Shaft

Shaft wear is a common problem when the belt conveyor is running. Therefore, it is very important to quickly solve the belt conveyor shaft wear problem within a limited downtime. The following introduces various belt conveyor shaft repair methods.

The Repair Method Of Belt Conveyor Shaft

1. Traditional welding method

The traditional repair welding process will cause thermal stress concentration on the shaft, tiny cracks on the shaft surface, changes in the material structure of the bearing seat, annealing and other undesirable factors. The shaft itself will bend and deform, and lose its original toughness and strength. Among them, the thermal stress concentration and tiny cracks will bring huge safety hazards to the shaft during its later use. The shafts of many important equipment have been bent or broken after repair welding.

2. Brush plating and thermal spraying methods

The brush plating coating of this method is limited by the amount of wear. Generally, the brush plating thickness of the electro-brush plating coating is less than 0.2mm. When the wear amount is greater than 0.2mm, the brush plating efficiency will decrease exponentially, and when the brush plating layer is too thick, the brush plating layer is easy to fall off during use, and the service life is short.

3. Online repair method

Sore’s carbon nano-polymer material online repair technology does not generate high temperature during the online repair process, which effectively protects the equipment body from damage and is not limited by the amount of shaft wear during the repair process. The material has good bonding properties, and through surface treatments such as baking oil, polishing, and cleaning during the repair process, the surface bonding area and bonding force of the material are increased to ensure that the material will not fall off. In addition, this technology can be repaired online without requiring a large amount of disassembly. Only the repaired parts need to be disassembled, which reduces or avoids disassembly, greatly shortens the company’s downtime, and reduces losses caused by sudden or major equipment problems.
