Abstract

The invention discloses a method for penetrating an inner stator to an outer stator of a split turbine generator. The inner stator is penetrated in the outer stator of the generator step by step under the cooperation of two cranes, the inner stator is moved into the outer stator step by step in a combination way of hoisting and dragging of the two cranes, and the position of the inner stator can be adjusted in real time in the penetrating process. Equipment for realizing the method disclosed by the invention is simple and reasonable in structure, safe and reliable and convenient to install and operate; and the problem for penetrating the inner stator into the outer stator of the split turbine generator can be solved.

Description

technical field [0001] The invention relates to a method for mounting an inner stator and an outer stator of a large generator. Background technique [0002] The inner and outer stators of split-type turbogenerators are very large and require special equipment to assemble them. The original turbogenerator inner and outer stators mainly have the following methods: [0003] The first type is the vertical wear of the inner and outer stators. Put the outer stator vertically on the fitting station, use the hoisting tool to lift the inner stator to the top of the outer stator, after the inner stator is stable, slowly lower the inner stator, and adjust the circumferential position and concentricity of the inner stator and the outer stator at the same time After the assembly is in place, the spring plate on the inner stator and the corresponding supporting structure on the outer stator are welded and fixed, and finally the inner and outer stators are assembled. This method require...
