| description | A Francis turbine includes a casing (300), a main shaft (100) inserted into the casing (300), a first runner (210) and a second runner (220) respectively disposed inside the casing (300) coaxially with the main shaft (100), and fixedly disposed on the main shaft (100) at an interval. The casing (300) includes a first volute (310) disposed on the first runner (210) in a sleeving manner and a second volute (320) disposed on the second runner (220) in a sleeving manner in sequence in the axial direction of the main shaft (100). A first inIet (3101) from a water inIet end to a nose end of the first volute (310) is formed in a side wall, facing the first runner (210). A second inIet (3201) from a water inIet end to a nose end of the second volute (320) is formed in a side wall, facing the second runner (220). |
