Problems solved by technology

[0004] 1) Inefficient and time-consuming;
[0005] 2) Defects such as cracks and slag inclusions are easy to occur, and the repair accuracy is low; and the welder's level has a lot of influence on the welding quality;
[0006] 3) The surface performance of the wheel house steel plate after welding is uneven;
[0007] 4) The thermal deformation is large, and the metal wall of the runner chamber is welded by this method, and the deformation is uncontrollable, which may easily cause the steel plate in the runner chamber to separate from the concrete to form a cavity;
[0008] 5) The thickness of the welding layer cannot be accurately controlled, and the grinding workload is relatively large

Abstract

The invention discloses laser cladding and detection equipment applicable to the surface of a hydroelectric power station unit runner chamber and an operation method. The laser cladding and detectionequipment comprises a flanged annular railway assembly; the flanged annular railway assembly is annularly arranged in the hydroelectric power station unit runner chamber; a moving trolley is placed onthe flanged annular railway assembly; an industrial manipulator is arranged on the moving trolley; and laser cladding equipment and detection equipment are arranged at the tail end of the industrialmanipulator. The laser cladding and detection equipment can be used for repairing work of the hydroelectric power station unit runner chamber, the mechanical property of a cladding layer on the surface of a steel plate of the hydroelectric power station unit runner chamber is further improved, the thermal deformation of the cladding layer is reduced, the thickness and surface accuracy of the cladding layer can be accurately measured, and at the same time, the repairing working efficiency of the hydroelectric power station unit runner chamber is improved.

Description

technical field [0001] The invention belongs to the field of repairing and testing equipment for hydropower equipment, and in particular relates to laser cladding and testing equipment and an operation method suitable for the surface of a runner chamber of a hydropower station unit. Background technique [0002] The runner chamber of the hydropower station unit is the operating area of ​​the water turbine. Since the surface of the steel plate in the runner chamber has been affected by sediment erosion, cavitation, hydraulic vibration, etc. in the water flow for a long time, the surface of the steel plate has been severely worn. It is impossible to stop the machine frequently to repair the steel plate surface of the runner chamber. Therefore, after each repair, the timeliness and wear resistance of the steel plate surface performance are put forward very high requirements. [0003] At present, the common repair of the steel plate surface of the runner chamber is done by manua...
