Abstract

The invention discloses a simulation practical training platform for realizing multi-mode centering of a steam turbine partition plate and belongs to the technical field of steam turbine partition plate centering equipment. The simulation practical training platform comprises a cylinder model, a partition plate model, a steel wire drawing practical training model stand and a dummy shaft practicaltraining model stand. The partition plate model and the steel wire drawing practical training model stand are placed in the cylinder model, centering adjustment of the steel wire drawing practical training model stand is conducted firstly, then partition plate centering adjustment is conducted, and steel wire drawing alignment practical training is conducted; and the partition plate model and thedummy shaft practical training model stand are placed in the cylinder model, centering adjustment of the dummy shaft practical training model stand is carried out firstly, then partition plate centering adjustment is carried out, and dummy shaft method simulation practical training is carried out. According to the simulation practical training platform in the invention, simulation of finding the center of the partition plate through various methods and centering of different centering materials through a same method can be achieved, the manufacturing cost of the models is low, the models are different from an actual steam turbine in price, and the simulation practical training platform can be used for simulation training of maintainers in university laboratories and related industry training.

Description

technical field [0001] The invention belongs to the technical field of centering equipment for steam turbine clapboards, and in particular relates to a simulation training platform for realizing centering of steam turbine clapboards in multiple ways. Background technique [0002] At present, finding the center of the steam turbine diaphragm is of great significance for the maintenance of the steam turbine, and poor centering will cause problems such as increased air leakage and rotor bending damage. However, when maintenance personnel who are inexperienced or have not participated in related work find the center, it takes a lot of time to meet the operating standards, and even the center is not accurate, resulting in a decrease in turbine efficiency and even machine damage. There is an urgent need for power plants, power-related enterprises, and relevant professional laboratories in universities to provide training for relevant technical personnel. However, because steam tu...
