Recently, the main shaft bearing of a 750KW motor in a chemical industry has suffered from wear problems. The wear depth on one side is between 0.4mm-1mm. The motor speed is 990r/min, the shaft diameter is 160mm, and the bearings it is equipped with are NU series. If this wear problem is not resolved promptly and properly, it will seriously affect the normal operation of the motor, which will in turn adversely affect the company's production.
Motor spindle wear
As one of the most important components of the equipment, the motor spindle's wear problem is much more difficult to solve. Traditional processes often require a lot of disassembly work when repairing motor spindle wear. This not only requires a lot of manpower and material resources, but also consumes a lot of production time and has a serious impact on enterprise production.
Traditional motor spindle wear repair solutions mainly include the following categories:
1, on-site brush plating process: Although this process can be repaired on site, it has problems such as insufficient stable coating bonding force and short service time after repair, making it difficult to meet the needs of long-term stable operation.
2, overall disassembly and then repair by welding and machining: This method requires the motor to be completely disassembled and then repaired and machined. The whole process takes a long time, and the high temperature generated during the repair welding process may have adverse effects on the material and performance of the spindle, affecting its service life.
3. Replacing new parts: Although replacing new parts can fundamentally solve the wear problem, the procurement cost of new parts is high, and the replacement process also requires a lot of time and manpower, which will cause production to be interrupted for a long time and bring large economic losses to the enterprise.
In this context, Sole carbon nanopolymer material technology emerged as the times require, providing a new and effective way to solve the problem of motor spindle wear.
Sole's carbon nanopolymer material repair technology utilizes the unique mechanical properties of carbon nanopolymer materials and targeted repair processes to achieve online repair of wear and tear on large shafts such as motors. The repair process is simple. Based on the unworn surface, the repair work can be completed on site using the tooling repair process.
Effect after repair of motor spindle wear
This technology has many significant advantages in repairing motor spindle wear:
1 has good adhesion: it can form a strong bond with the surface of the spindle to ensure that the repair layer is not easy to fall off and ensures the stability of the repair effect.
2, good comprehensive mechanical properties: It has excellent compression resistance and wear resistance, and also has the elastic deformation ability of metal, which can well adapt to the various forces and working conditions that the spindle endures during operation.
3, high repair efficiency: There is no need to disassemble the equipment in large quantities. Under normal circumstances, the repair work can be completed within 4 hours, which greatly shortens the equipment downtime and reduces the impact on production.
4, not limited by the amount of wear: The repair process is not limited by the amount of wear on one side of the shaft, and can be effectively repaired regardless of the degree of wear.
5, long service life: Carbon nanopolymer materials will not produce metal fatigue wear during use. Under the premise of normal maintenance of the equipment, its service life after repair is even higher than the service life of new parts.
To sum up, Sole carbon nanopolymer material technology provides a powerful solution for enterprise equipment repair and maintenance in repairing motor spindle wear due to its high repair efficiency, online repair, and low comprehensive repair cost. It can greatly reduce the production cost of the enterprise and ensure the continuous and stable operation of the enterprise's production. It has broad application prospects and important practical value in the field of industrial equipment maintenance.
