| 摘要 | PURPOSE: To feed enough coolant to a cut blade by energizing a turbine rotor partially in the axial direction by liquid stream, activating a collection nozzle, which is arranged at an outlet of the rotor to collect the liquid stream after deflection of this stream, as a mixing passage for sucking air and residual water from a turbine casing. CONSTITUTION: A rotor 20 is energized axially by a liquid stream 25 from a nozzle 24, and this stream 25 hits a rotor blade 21 as a vector characterized by a tangential direction component from 80% to 96%, an axial direction component from 20% to 40%, and radial direction component from 0% to 15%, and goes out from the rotor blade 21 with having the tangential direction component, the axial direction component, and the radial direction component. A collection nozzle 26 for collecting the stream 25 after deflection of this stream 25 is arranged at an outlet of the rotor 20, and functions as a mixing passage for sucking air and residual water from a turbine casing.
