Document Type and Number:
WIPO Patent Application WO/2017/034124
Kind Code:
A1
Abstract:
The present invention relates to a rotating blade coupling structure having a blade angle varying function and a pump having the same, and is advantageous in that a blade angle adjustment unit, which rotates all shafts of a plurality of blade portions that are rotatably coupled to a rotating body at an even interval, and which varies the angle of the plurality of blade portions accordingly, not only makes it possible to reduce the amount of initial starting load current that is consumed to initially rotate the rotating body, which has the plurality of blade portions provided at an even interval, forwards/backwards, but also enables automatic flow rate adjustment.
