摘要
国华定洲发电厂一期2×600MW机组汽轮发电机采用双流双环式密封瓦,在历次检修过程中,多次发生密封瓦径向间隙超差情况。主要探讨修复双流双环密封瓦所遇到的问题以及工艺方法。
the dual stream loop seals tile is applied on the 2 ×600MW Unit 1 turbine generator of Guohua Dingzhou Power Plant. In the previous inspections, many occasions, such as a tile radial clearance of an uhra-poor situation had happened, therefore, this paper focus on the investigation of the technology used to solve the problem in the case of the dual stream loop seals.
