Device for axially conveying fluids

The invention relates to a device for axial fluid conveying, composed of a tubular the rectangular hollow body of a liquid is axially formed, the hollow body middle shaft to aiming provided with one is located in the hollow body is a motor stator and a conveying of rotary magnetic bracket, on the conveying of magnetic bearing is provided with a rotor blade; the magnetic bearing and hydrodynamic bearing shaft linked, and bearing of conveying with an active for magnetic thrust bearing, and a magnetic radial bearing and a liquid dynamic pressure radial bearing. The delivering by three magnetic supporting, wherein radial bearing with the periphery and rigidity efficient damping, thus and avoid through the critical and speeds and an adverse impact of rotor liquid dynamic pressure and also machine. Therefore magnetic bearing and hydraulic driven shaft bearing ring.
