Abstract
A zero leakage shielding magnetic force axial flow pump comprises a motor stator, a stator housing, a permanent magnet rotor, an axial flow pump impeller and a pump shaft. Inside of the stator housing is provided with a shielding sleeve coaxially; end faces of two ends of the stator housing are in seal welding with the shielding sleeve; the motor stator is disposed between the stator housing and the shielding sleeve along an inner circumference of the stator housing; the shielding sleeve is formed by a tubular magnetizing member; bearings are disposed in two ends of the stator housing; the pump shaft is disposed in the shielding sleeve coaxially; two ends of the pump shaft are disposed in the bearings; the permanent magnet rotor is fixed to the pump shaft; and the axial flow pump impeller is fixed to the pump shaft. The zero leakage shielding magnetic force axial flow pump employs rotating magnetic field generated by the stator to drive the permanent magnet rotor, which drives the impeller on the pump shaft; has no dead angle during liquid conveying and has less damage on substance in the liquid; prevents conveying medium from being polluted by leakage through the shielding sleeve which isolates the stator from the conveying medium; and realizes high working pressure of the shielding sleeve with the stator as the base.
Description
Technical field
