摘要

针对300 MW机组汽轮机中压第10级隔板及叶片断裂事故进行了断裂叶片断口形态分析

认为断裂事故的主要原因是制造过程中

静叶定位焊接工艺不佳

焊接质量较差所致。对此提出了更换备用中压转子的处理方案

并根据此次事故对同型运行机组提出了改进建议。

Abstract

Directing against the crippling failure of MP 10th diaphragm and blades of steam turbine equipped for a 300MW unit

the occurring process and damage degree of said failure have been presented

the fracture form of crippled blades and the causes resulting in crippling failure being analysed

and a disposal scheme for said failure being put forward

and recommendations for improving similar units in operation being suggested based on this failure.
