Integrated shaft-free motor axial flow pump

The invention relates to the technical field of water pumps and in particular relates to an integrated shaft-free motor axial flow pump. The integrated shaft-free motor axial flow pump comprises a pump enclosure of which the two ends are provided with connecting flanges, wherein the middle of the inner hollow cavity of the pump enclosure is provided with a pump impeller; the inner hollow cavity of the pump enclosure on the downstream side of the axial flow pump is provided with a guide vane; the outer edge of the pump impeller is provided with a rotor fixing ring; a driving motor rotor is assembled on the rotor fixing ring; the rotor fixing ring is fixed on the inner side of the pump enclosure by virtue of a fixed ring bearing; the part, corresponding to the driving motor rotor, on the inner side of the pump enclosure is provided with a groove; and a driving motor stator is assembled in the groove. The integrated shaft-free motor axial flow pump disclosed by the invention is characterized in that the shaft-free motor and the axial flow pump are integrated into a whole, so that the axial flow pump can be integrally installed in the straight pipe section of a pipeline, and the compactness and mute effect of the axial flow pump can be obviously improved. The integrated shaft-free motor axial flow pump has the advantages of simple system arrangement, small occupied space and easiness for construction and design.
