Generators are indispensable equipment for all power companies in the form of power generation, and an important part of power plants. With the continuous development of high-parameter, high-power, and large-capacity units, especially the development of thermal power generation, the rotor, The journal requirements are getting higher and higher due to iron filings and impurities in the lubricating oil system; during the start-up of the unit, due to the influence of low oil temperature or oil pressure, the oil film is not formed and the bearing bush and journal are worn.

The main shaft of a steam turbine is a shaft that connects the runner of the steam turbine to the rotor of the generator and transmits torque. Long-term use makes the shaft diameter severely worn, and the size becomes smaller and cannot be used normally. By using laser cladding, the shaft diameter can be restored to the original design size, the service performance and life of the parts can be restored, and the economic benefits can be improved.

The compressor continuously sucks in air from the atmosphere and compresses it; the compressed air enters the combustion chamber, mixes with the injected fuel and burns to become high-temperature gas, and then flows into the gas turbine to expand and perform work, pushing the turbine wheel to carry the compressor. The impeller rotates together;

The blade preparation process is complex and the use environment is harsh. How to achieve high-quality repair of blades has always been an urgent problem for gas turbines and aerospace engines.
