KR970016168A - Impeller of magnet pump in which plastic magnet is molded integrally and its manufacturing apparatus - Google Patents

Abstract

The present invention relates to an impeller of a magnet pump formed of a plastic magnet and an apparatus for manufacturing the same, in a magnet pump used for hot water circulation of a boiler or for acid transport of chemicals, the stator 21 of the motor housing 20. In the impeller of the magnet pump 1 for forcibly circulating fluid while the driving magnet 26 is rotated together with the rotor 22 and rotated together with the driving magnet 26 when power is input, the driven magnet housing 31 ), And the impeller of the magnet pump, in which the plastic magnet is integrally formed, is formed by the molding apparatus 40 having the magnet 42 embedded therein. It is to be landed by the magnetizing device 45, because the plastic magnet is magnetized by the magnetizing device, the magnetic field is maximized It can be manufactured and provided, and because the use of superhard mold, the mold wear by the insert of ceramic bushing is small, so the mold can be used for a long time, and by using anisotropic ferrite powder, the manufacturing cost can be lowered and productivity can be improved. Of course, since the weight of the impeller is lightened, the durability of the magnet pump is enhanced, and the weight of the pump is reduced, so that the load due to the rotational vibration applied to the rotary support, that is, the bushing, the thrust bearing, and the impeller shaft can be taken.
