摘要
介绍了为九子溪电站水轮机增容研制的新型转轮 .实际运行结果表明 ,在电站工况不变和未采取其他措施情况下 ,新转轮使原机组功率增容相对幅值达 1 5 .3% .机组在不利的小负荷工况下运行近 40 0 0 h,未见磨蚀痕迹 ,抗空蚀、抗磨蚀性能优于原转轮 ,新转轮完全可替代老的 HL70
The new runner is made by the requirement of the water turbine upgrading of the Jiuzixi Hydro Powerplant. The test results show that the rated power is raised by 15.3% after using the new runner. There is no abrasion on the new runner after running 4000 h . The characteristics of the new runner are better than old runner. The research of the new runner is a success , and the new runner can be used to replace the HL702 runner.
