What are the repair methods of high voltage motor shaft wear?
2020-12-31
Equipment operation will be damaged or reach the life cycle, mining equipment is no exception. The high-voltage motor of a mining suction pump in an enterprise has a shaft wear problem, with a wear amount of 1-2mm. As the net weight of the high-voltage motor of the mine suction pump is nearly 10 tons, it is installed in the pump room 500 meters underground, the pump room has a stepped structure, and there is no transportation track, so it cannot be operated in a narrow mine hole in known large mechanical lifting equipment, and can only be repaired on site. In view of this situation, do you have a better repair method?
There are many methods for repairing high-voltage motor shaft wear, such as repair welding, spraying, brush plating, etc. Although these traditional shaft wear repair methods continue to this day, they all have great disadvantages. For example, the thermal stress generated by the repair welding process has a great impact on the shaft material, which not only seriously affects the operation of the equipment, but also greatly shortens the life cycle of the shaft; spraying, brush plating process on the shaft wear size and on-site construction environment has strict requirements, especially in the face of some sudden emergency, large equipment, disassembly complex, serious wear and other equipment problems, these repair methods are obviously more than enough.
In view of the wear of the high-voltage motor shaft, Xiaobian suggested to repair it with Solay carbon nano-polymer material technology, which does not need to worry about the above problems. The technology does not produce high temperature during the online repair process, protects the equipment body from damage, and is not limited by the amount of unilateral wear of the shaft during the repair process. Moreover, the technology has no strict requirements on the on-site construction environment, and can be repaired on-site online, reducing or avoiding disassembly. Under normal circumstances, the repair can be completed in just a few hours, greatly shortening the downtime of enterprises, and reducing the sudden or major Losses caused by equipment problems.
