The invention discloses an active electromagnetic bearing
impeller pump. The active electromagnetic bearing
impeller pump is mainly composed of a radial direction electromagnetic bearing rotor, a
stator, a
thrust bearing, a sensor and a bracket thereof, an
impeller and a pump shell. The bearing seat and the impeller are made as an integrated body, the impeller (rotor) of the pump is embedded with the soft magnetic material (magnetic steel and the like) with good permeability, the pump shell (
stator) is provided with a coil, which is connected with the
electric current for generating the
rotating magnetic field, driving the impeller for rotating and realizing the action of the pump. Another
magnetic bearing (in radial direction and axial direction) is used for rotating and locating the main shaft and stopping the displacement in radial direction and axial direction. The rotor is soaked in the medium for rotating; the surface contacting the fluid is covered by the
corrosion-resistant material, so that the pump has no sealing element of any type inside. The active electromagnetic bearing impeller pump is simple in function, the defect of the common impeller pump, which is easily worn and required to be sealed can be greatly overcome and the active electromagnetic bearing impeller pump has good application prospect.
