混流式水轮机转轮是水电机组中制造难度最大的部件之一,各国都为此倾注了很大心血。随着机组单机容量的不断增大,转轮直径也随之增大,促使转轮自其毛胚材料、结构乃至工艺出现巨大变化。本文依据半世纪以来国际、国内大型转轮制造历程,重点介绍了国内在转轮制造中取得的成就。 Francis turbine runner is one of the most difficult parts in the hydropower generating units, and all countries have devoted a great deal of effort. With the single capacity of the unit continues to increase, the diameter of the wheel also increases, prompting the wheel from its blank material, structure and even great changes in technology. Based on the manufacturing history of large-scale and large-scale domestic and international rotors in the past half century, this article mainly introduces the achievements made in the manufacturing of runners in China.
