Abstract

PURPOSE:To improve efficiency of a water wheel and performance of cavitation by arranging an intermediate blade shorter than the blade length of a runner main blade in a pass at the entrance side between the two runner main blades adjoining each other in practically parallel. CONSTITUTION:A runner 2 is fixed on the lower end of a main shaft 1 and the runner 2 is constituted by a runner crown 3, a runner band 4 and a plural number of runner main blades 5. And, an intermediate blade 6 is provided between said adjoining two runner main blades 5, 5 in practically parallel with the runner main blades 5. This intermediate blade 6, having a vane type cross sectional shape and vane length shorter than that of the runner main blades 5, is arranged on the circumference of a circle within a prescribed range at the runner inlet side. The tip in the inlet side of the intermediate blade 6 is arranged on the same circumference of a circle as the tip in the inlet side of the runner main blade 5.
