混流式水轮发电机组广泛适用于高、中、低各种水头,一般从10米至300米,其特点是水流流经转轮叶片时先沿着辐向进入,然后逐渐变成轴向离开,因而混流式水轮发电具有运行可靠,结构简单,平均效率高等特点。
Francis turbines of both vertical and horizontal types are suitable for water head from 10m to 300m. Its feature is that the water flow enters the runner inward in a radial direction, changes direction gradually and then passes out axially. Francis turbine is characterized by reliable operation, simple construction, and high efficiency, etc.
