溪洛渡水电站哈电机组水轮机座环现地机加工工艺

On-site Machining Technology of Turbine's Stay Ring Manufactured by HEC in Xiluodu Hydropower Station

从底环安装面加工、止漏环加工、导向条加工、座环上法兰面加工及座环上下镗口加工6个方面对溪洛渡水电站哈电机组水轮机座环现地加工进行了详细叙述。与传统的加永久垫片方式相比,座环现地加工具有加工精度高、稳定性好、止水效果好等优势。

The on-site machining of stay ring of turbine manufactured by Harbin Electric Corporation（HEC） is introduced from the processing of bottom ring mounting surface, runner band seal, guiding strips, upper flange surface of stay ring and upper and lower borings of stay ring. Comparing with traditional way of adding permanent gaskets, the on-site machining of stay ring has high precision, good stability and better scaling effect.
