Document Type and Number:
WIPO Patent Application WO/2016/208867
Kind Code:
A1
Abstract:
The present invention relates to a bidirectional axial-flow pump that selectively suctions and discharges fluid in both directions. A bidirectional axial-flow pump, according to an embodiment of the present invention, comprises: a rotor having a rotary shaft that is inserted through the center thereof and protrudes from opposite ends thereof; a stator disposed around the rotor to rotate the rotor by means of a magnetic field; a motor casing that surrounds the rotor and the stator such that opposite ends of the rotary shaft protrudes from the motor casing; first and second impellers coupled to the opposite protruding ends of the rotary shaft, respectively, to rotate together with the rotary shaft; and a suction/discharge casing that surrounds the first and second impellers and the motor casing to form a fluid passage through which fluid passes and to form an inlet for suctioning fluid and an outlet for discharging the fluid. Thus, it is possible to implement high lift and to enhance a discharge force.
