本文以溪洛渡机组为研究对象,从两方面介绍了大型混流式水轮机导水机构厂内预装:一是导水机构支撑方案,二是导水机构拉开度试验方案。在传统工艺的基础上,注重技术改进与革新。通过方案的探讨、制定及成功实施,解决了大型导水机构厂内预装的一系列难题,填补了我公司700MW级混流式水轮机导水机构厂内预装的空白。
In this paper, the Xiluodu unit as the research object, introduced from two aspects large-scale Francis turbine aqueduct factory pre-installed: First, the water guide mechanism support program, and second, the water guide mechanism opening test program. On the basis of traditional technology, pay attention to technological improvement and innovation. Through the discussion of the plan, formulated and successfully implemented, a series of problems preloaded in the large-sized water guiding mechanism factory were solved, filling the gap pre-installed in the water guiding mechanism of the 700MW-class Francis turbine of our company.
