The main shaft and rotating frame of wind turbine are the key components of large wind turbine. After 3-5 years of operation, the journal position of the main bearing position or the working surface of the turret are seriously worn and roughened. If maintenance is not carried out, it may cause great losses in the future.
The traditional repair method of the main shaft and other parts needs to go through the process of disassembly, hoisting, repair and reinstallation. The cost of disassembly and hoisting is high, and the operation cycle is long. We can provide a complete set of flexible online repair solutions, implement remanufacturing process repair for worn out out of tolerance parts and failed parts, and can process them online to the drawing size to quickly restore fan operation. This repair plan is not only short in maintenance cycle, reliable and stable in process, flexible and convenient, but also can selectively improve strength, wear resistance and service life.
