摘要
Ｄ１７９ａ 水轮机转轮是东方电机厂在八盘峡水电厂５ 号水轮机改造过程中， 研制的一个性能优良的模型转轮。实践证明该转轮比瑞典原 Ｋ Ｖ４ 转轮大流量区的效率明显提高， 空蚀性能优良， 其最优工况点效率可比原转轮提高２２ ％ ， 设计点的效率在９２ ％ 左右， 是２０ ｍ 水头段性能优良的转轮之一。 Ｄ１７９ａ 水轮机转轮在八盘峡水电厂５ 号水轮机改造的情况和现场试验的结果， 可供其他水轮机改造和优化时参考。
D179a type runner of turbine is a model runner with the good performances for the transformation of No 5 turbine in Bapanxia Hydro Station, developed by the Orient Motor Factory The practice shows that its efficiency in large discharge area is obvious higher than the original kV4 runner made in Sweden and it has good cavitation performances Its efficiency of the optimum working condition point could increase 2 2% than that of the original runner Its efficiency at design point is about 92% Thus it is one of runners with good performances for the water head of 20 m The application of D179a type runner in the transformation of the No 5 turbine in Bapanxia Hydro Station and its field test results could be used for reference in the transformation and optimization of other turbines
