Abstract
An axial tip turbine driven pump in which a first fluid pumped by an inducer is driven by a second fluid that reacts with a turbine blade extending from a shroud on the inducer. The inducer includes a set of screw thread blades and a second set of partial blades that are covered by a shroud in the aft section of the inducer. A row of turbine blades extends from the shroud and into a manifold that forms the outer casing for the pump. The fluid flow through the manifold reacts with the turbine blades and drives the inducer to pump the fluid from the inlet and through guide vanes downstream from the inducer. The fluid passing through the turbine blades is collected in an outlet collector manifold and discharged into the fluid flowing through the guide vanes. The inducer with the turbine blades is rotatably supported within the housing formed by the guide vane support member and the manifold casing. The swirl flow direction of the turbine blades is opposite to that of the swirl flow in the inducer. The structure that rejoins the two fluids redirects the turbine blade flow into the same swirl direction as the inducer flow.
