Abstract
The invention discloses a kind of single shaft driven level 3 of axial flow pump, including: power source, pumping out, transmission shaft, export fixed vane, the third stage impeller, the second impeller, the first stage impeller, imported fixed vane, pump inlet, the first transmission cone gear, the first cone gear transmission device, the second driving cone gear and the second cone gear transmission device, the invention can realize the opposite steering of the two adjacent impellers by fixing the guide vane and the bevel gear transmission in the impeller hub. With compact structure and small axial size, this single-shaft driven three-stage counter-rotating axial-flow pump can greatly improve the head of the axial pump and widen the efficient zone.
