Abstract

The invention discloses a method for installing a dynamic balance counterweight of a hydroelectric generator. Through the increase of the fixed block, the fixed block is welded on the arm of the rotor center body, and the fixed block is processed with threaded holes, and the installation of the counterweight is realized by means of bolt fixing, which is beneficial to the balance weight in the later stage of the dynamic balance test. The adjustment of the weight and position avoids the inconvenience caused by the adjustment of the counterweight directly by welding and fixing the counterweight. The present invention can be applied to the installation of the dynamic balance counterweight of large and medium-sized hydroelectric generator sets, and is convenient and fast for the installation and adjustment of the counterweight, and can reduce the installation man-hours of the counterweight for the dynamic balance test and save the installation and maintenance period the goal of.

Description

technical field [0001] The invention relates to the field of hydraulic turbines, in particular to a method for installing a dynamic balance counterweight of a hydraulic turbine generator. Background technique [0002] At present, some power plants at home and abroad have the need for transformation after years of operation. During the transformation process, it is necessary to carry out a dynamic balance test. Since the dynamic balance test has been carried out in the initial installation stage, there are a large number of counterweight blocks on the rotor. Therefore, it is no longer possible to fix the weights by bolts in the rotor center body. Especially for some units that were put into operation in the 1980s and 1990s, the rotor center was determined by the degree of technological development and the one-sidedness of cognition at that time. There are no bolt holes designed on the body support arm, and due to the limitation of the rotor center body space, it is impossible...
