Abstract

1,047,891. Axial-flow pumps; hydraulic turbines. SOCIETE GRENOBLOISE D'ETUDES ET D'APPLICATIONS HYDRAULIQUES. Jan. 16, 1964 [Jan. 19, 1963], No. 2059/64. Headings F1C and F1T. [Also in Division B7] A reversible hydraulic machine comprises a single or multi-stage axial-flow pump, turbine or turbinepump disposed in an elongated duct and having rotor and stator blades possessing symmetries of form or orientability to ensure identical characteristics for both directions of flow. The blades 22 of a pump impeller are rotatable about their axes of symmetry through an angle of, say, 40 to 70. degrees bisected by the axis I-I. Thus the direction of flow as well as its speed is controlled by the angular position of the blades 22. The outer casings 3, inner casings 5 and guide vanes 26 are symmetrically arranged about a plane perpendicular to the axis X-X. The angle of inclination of the end 28 of each guide vane 26 relative to the axis X-X decreases from the respective outer casing 3 to the respective inner casing 5 and it may be zero at the casing 5 or a negative value as shown. The inner casings 5 may house the driving motor or motors and the mechanism for rotating the impeller blades. In an alternative embodiment, Fig. 4a (not shown), the direction of rotation of the impeller is reversed to reverse the direction of flow, and the impeller blades are rotatable through an angle of, say, 20 to 35 degrees to one side of the axis I-I or otherwise rigidly secured to the impeller. Further, the impeller blades are of S-shape cross section and have rounded leading and trailing edges, and the guide vane ends adjacent and on one side of the impeller are inclined, with respect to the axis X-X in the opposite direction to those on the other side of the impeller, the angles of inclination of these ends increasing from the outer to the inner casings.
