Abstract

839,964. Hydraulic turbines. BOVING & CO. Ltd. April 2, 1958 [Jan. 7, 1957], No. 37477/56. Class 110 (3). Air holes in the wall of the hollow nose-piece of a Francis turbine runner are provided with an injector device utilizing the flow of the water stream to induce a flow of air outwardly through the holes and into the water stream passing to the suction tube of the turbine. The injector comprises a frusto-conical boss 13 framing the outside of each air hole 8 and cooperating with an annular cover plate ring 14 surrounding the nose-piece and separated from it by supports 15 which may be either rigid or resilient, part of the water stream flowing between the boss and the cover plate ring with locally increased velocity and reduced pressure. Each hole 8 is connected by the pipe 9 to an airspace supplied with atmospheric air, from a control valve, through the pipes 12. The Provisional Specification gives recommended proportions for the injector.
