Title:
SELF-RUNNING PUMPING MACHINE
Document Type and Number:
Japanese Patent JP2940600
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To smoothly activate a water turbine, used in a pumping machine for lifting water, at stable rise of revolving speed even upon a change in its head, while saving the setting and control of its start opening degree.
SOLUTION: A pumping machine comprises an axial flow water turbine adapted to rotate through the action of flowing water, and a centrifugal turbopump. The water turbine has runner blades 1 each internally formed with a hollow flowing water passage 10, in which part of flowing water passes. The water inside the passages 10 is centrifugally discharged into a casing 20 arranged outside the blades 1 and is then taken out thereof as pressure water.
