汽轮机组高压缸进汽端结合面漏汽处理

Steam Leakage Treatment on Inlet Adjoining Plant of Turbine HP Cylinder

简要地介绍了 2 0 0 MW机组高压缸结合面漏汽的处理方法 ,并结合新电公司 3 0 1号机组高压缸进汽端结合面漏汽问题 ,详细介绍了采用局部补焊研刮方法的处理过程。经实践证明该方法不仅效果好 ,而且缩短了处理工期 ,为同类机组在同一条件下处理此类问题提供了借鉴。

Steam leakage treatment method on adjoining plane of 200MW turbine HP cylinder was introduced briefly.Through the steam leakage treatment on HP cylinder inlet adjoining plane of No.301 turbine in Xinyu Power Generation Co.As an example,the procedure of partial method fulfilled good result,reduced the treating time and provided a good example for resolving the same kind problem of same type turbine.
