DRIVE UNIT OF MAGNETIC COUPLING PUMP AND MAGNETIC COUPLING PUMP UNIT |
摘要 |
Provided is a drive device for a magnetic coupling pump, in which leakage of magnetic flux to the outside and the effect of external magnetic fields are suppressed. This drive device for a magnetic coupling pump comprises: a drive magnet (219) facing a driven magnet (19) of a magnetic coupling pump (100) across a gap and disposed further to the outside than the driven magnet relative to the rotational axis (A) of the pump; a cup (220) having a cup cylindrical part (221) formed of a ferromagnetic material and forming a cylinder shape about the rotational axis (A), the drive magnet being fixed to the inside of the cup cylindrical part; a motor (210) for rotating the cup about the rotational axis; and a casing body (231) having a cylindrical part (232) inside which the cup is disposed across a gap, the casing body being formed of a paramagnetic material and forming a cylinder shape. |
