TURBOPUMPE MIT MAGNETISCH GELAGERTEM FLUEGELRAD |
摘要 |
A turbo pump is disclosed, having a magnetically supported impeller. The turbo pump includes a casing (31) made of a non-magnetic material, an impeller (32) provided in the casing (31), a triaxial controlled magnetic bearing provided outside of the casing (31) for magnetically supporting the impeller (32), and a rotor (37) magnetically coupled to the impeller (32) for rotating the impeller. The triaxial controlled magnetic bearing includes a magnetic member (35) provided on one plane of the impeller and a plurality of electromagnets (39) provided in the casing in such a way as to be opposed to the magnetic member. Coupling between the impeller (32) and the rotor (37) is effected by a plurality of permanent magnets (33, 38) respectively provided thereon. In another aspect of the invention, a plurality of stator windings for generating the rotating magnetic field may be provided on the side of the stator in place of rotating means utilizing a magnetic coupling. |
