HYDRAULIC TURBINE WITH INCREASED POWER CAPACITIES

摘要

A hydraulic turbine with increased power capacities for new or existing hydroelectric installations. The turbine has a larger axial runner wheel (2') and a reshaped runner ring (34) peripherally extending around the runner wheel. A draft tube (12') with a larger elbow section extends on a downstream side of the runner ring. (34). A water supply port (42) extends around a rotation axis (14) of the r unner wheel (2') on an upstream side of the runner ring (34), and is adapted to produce a centripetal water flow swirling around the rotation axis of the runner wheel. A turning passageway (16) extends between the water supply port (42) and the runner ring (34), and is adapted to guide and redirect the centripetal water flow in a substantially axial direction of the runner wheel. An axial distributor (18) extends between the turning passageway (16) and the runner ring (34).
