Abstract

The invention provides a steam turbine rotor vapor seal tooth repairing system and method, and relates to the technical field of repair of steam turbine rotors. The steam turbine rotor vapor seal tooth repairing system comprises a base, a turning device and a laser cladding device, wherein the turning device and the laser cladding device are arranged on the base; the turning device comprises chucks, supporting seats and a movable knife rest; the chucks are arranged at two ends of a steam turbine rotor and are used for clamping the steam turbine rotor; the supporting seats are arranged on the lower portion of the steam turbine rotor and are used for supporting the steam turbine rotor; the movable knife rest is used for turning the steam turbine rotor; and the laser cladding device comprisesa laser device which is arranged on a side of the steam turbine rotor and can move along the steam turbine rotor. The technical problems that in the prior art, a steam turbine high-and-medium-pressure rotor is heavy and huge, a traditional turning tool cannot meet a clamping requirement of the rotor, and thus the steam turbine rotor is difficult to repair are solved, the clamping requirement forthe steam turbine rotor is met by the supporting seats, and the repair operation can be carried out at high quality and high efficiency.

Description

technical field [0001] The invention relates to the technical field of steam turbine rotor repair, in particular to a steam turbine rotor steam seal gear repair system and method. Background technique [0002] A steam turbine is a rotary power machine that converts the energy of steam into mechanical work. It is mainly used as a prime mover for power generation. It can also directly drive various pumps, fans, compressors and ship propellers. It can also use the exhaust steam of the steam turbine Or intermediate steam extraction to meet the heating needs of production and life. The steam turbine is mainly composed of rotor and stator. The rotor includes the main shaft, impeller, moving blade and coupling, etc. The stator includes the steam inlet part, cylinder, diaphragm and static blade grid, steam seal and bearing. The types of rotors include set rotors, integral forged rotors, welded rotors and combined rotors, etc. The integral forged rotor refers to the impeller, shaft ...
