Problems solved by technology

[0004] At present, most power plants in China use manual surfacing welding to repair the guide vane. First, the abrasive part of the guide vane shaft is welded to the original size or larger than the original size, and then the welded part is ground to the ideal surface by turning or grinding. Or close to the ideal surface, due to the large area of ​​surfacing welding, the labor intensity of workers is high, the working environment is harsh, which seriously endangers the health of workers, and there is a certain randomness in manual surfacing welding, it is difficult to guarantee the welding quality

Abstract

The invention discloses a water turbine guide blade repair automatic surfacing device. The water turbine guide blade repair automatic surfacing device comprises a control cabinet, a rotating chuck, aclamping tail bracket, a water turbine guide blade, a welding gun, a speed reduction motor, an XYZ stepping motor linear modulus assembly, a guide rail, and a rack. Different welding modes are selected, through a PLC, the speed reduction motor is controlled to rotate, a stepping motor is controlled to enable the welding gun to flexibly work in space, and welding of a water turbine guide blade shaft and guide blades can be finished. Welding efficiency is improved, and the problems that due to manual surfacing repair, labor intensity is large, and surfacing quality is hard to ensure can be solved.

Description

technical field [0001] The invention is designed in the fields of hydropower generation, automatic control, and remanufacturing, especially in the field of surfacing welding and repairing rotary parts such as hydraulic turbine guide vanes and valves. Background technique [0002] The guide vane is an important part of the turbine, generally evenly arranged on the periphery of the runner, and its function is to guide the water flow into the runner evenly, and by adjusting the opening of the guide vane, the flow of the turbine can be changed to meet the requirements of generator load adjustment changes , It can also play the role of sealing water when all are closed. [0003] The movable guide vanes of the hydro turbines in the power station have been operated in a wet season, and the three-section journals and blades of the guide vanes are worn to varying degrees. After the guide vane is worn, the rotation resistance of the guide vane increases, the rotation is inflexible, t...
