Furthermore, a sensor arrangement is provided which can detect an inclination of the rotation axis of the rotor.
Claims19
A pump comprising:
- a housing with an upstream inlet and an downstream outlet and a fluid channel with a channel axis, said fluid channel being arranged between the inlet and the outlet;
- a rotor with an upstream and a downstream end, wherein the rotor is arranged in the fluid channel, comprises a blading for the delivery of the fluid, and is mounted upstream by a mechanical or hydrodynamic bearing;
- a motor which is arranged in the housing, so that the rotor can be brought into rotation about a rotation axis;
- a passive magnetic bearing comprising a magnetic ring that is arranged in the housing outside of the fluid channel;
- a sensor arrangement for detecting an inclination of the rotor axis of the rotor, wherein the sensor arrangement is arranged downstream from the rotor;
- and
- wherein the pump is an axial pump.
