Turbine pump.

摘要

An impeller is rotatably supported on a housing, having paddle-like open-vane type vanes. An annular pump channel is provided in the housing around the periphery of the impeller and around the vanes. A stripper is provided in the pump channel between an inlet port of the latter and a discharge port. A pair of bosses are located on the housing in the pump channel on opposite sides of the impeller about midway between the inlet and discharge ports. The bosses each have an edge obstructing a radially inner fraction of the pump channel to intercept inertially separated vapour in the inner fraction having a velocity component in the direction of rotation of the impeller.
