  • Francis-type runner for a hydraulic machine, hydraulic machine including such a runner, and method for assembling such a runner
    Patent number: 9175662
    Abstract: The present invention relates to a Francis runner for a hydraulic machine that comprises a belt with a rotational symmetry about a central axis of the runner, a ceiling with a rotational symmetry about the axis, and a plurality of blades (21, 22) extending between the ceiling and the belt. The runner also includes at least two elements (41, 42, 43, 61, 62, 63) partially defining at least the belt and/or the ceiling while at least one edge (231, 232, 241, 242) of a blade (21, 22) is inserted between the two elements defining the belt and/or the ceiling.

  • METHOD FOR FABRICATING A FRANCIS-TYPE RUNNER FOR A HYDRAULIC MACHINE, AND RUNNER FABRICATED USING SUCH A METHOD
    Publication number: 20150192101
    Abstract: The method relates to the fabrication of a Francis-type runner for a hydraulic machine. The Francis-type runner includes: a runner band including at least two elements partially defining the runner band, a runner crown including at least two elements partly defining the runner crown, and a plurality of blades extending between the runner crown and the runner band. The blades are each fitted in between two elements of the runner band and between two elements of the runner crown. The method includes fabricating separately the blades, the elements of the runner band and the elements of the runner crown. All the elements of the runner band are then welded to the blades using an electron beam welding method. All the elements of the runner crown are then welded to the blades using an electron beam welding method.
