Problems solved by technology

[0003] The lifting process of the traditional technology is relatively cumbersome, and the retaining ring is easy to slip during the heat-fitting process.
Due to the problems in the above process, the temperature of the retaining ring is likely to drop below the thermal expansion temperature before the heat fitting is in place, resulting in the failure of the heat fitting of the retaining ring, poor fitting accuracy, and not easy to fit

Abstract

The invention discloses a process method and apparatus of thermal sleeving of a rotor retaining ring of a turbo-generator, and belongs to the field of thermal sleeving of the rotor retaining ring of the turbo-generator. The process method includes: heating of the retaining ring, positioning of the retaining ring, and thermal sleeving of the retaining ring. The apparatus comprises a heating device,a positioning trolley and a retaining ring sleeving hydraulic system. According to the process method and the apparatus, the thermal sleeving precision of the retaining ring can be improved, the sleeving and dismounting quality of the retaining ring can be guaranteed, the sleeving is fast, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of heat sleeve of a turbine generator rotor retaining ring, in particular to a process method and a device for heat sleeve of a turbine generator rotor retaining ring. Background technique [0002] The retaining ring seam of the turbogenerator rotor and the shaft are interference fit, which needs to be heated and assembled. The traditional shrink-fitting process of the retaining ring usually uses a heating furnace to heat regularly; after heating, the retaining ring is lifted out of the heating furnace with a fiber sling, and the retaining ring is lifted to the end of the rotor after adjusting the way the sling hangs the retaining ring; Set the retainer by hammering or picking hooks. [0003] The lifting process of the traditional technology is relatively cumbersome, and the retaining ring is easy to slip during the heat-fitting process. Due to the problems in the above process, the temperature of the reta...
