Abstract
(EN)
The utility model discloses a micropump with magnet rotor of moulding plastics, including mainly assembling the pump body that constitutes by pump head, pump chamber, pump cover, motor stator, rotor, center pin, impeller part spare, the rotor cup joints on the center pin, its characterized in that rotor part and rotor on the magnet part of required installation, two parts adopt magnetic material to mould plastics integrated into one piece to connect to formation is fused in the magnet rotor of moulding plastics of an organic whole, impeller integrated into one piece in the tip of the magnet rotor of moulding plastics. The utility model discloses with magnet essential on rotor, the rotor to and the impeller adopts magnetic material once only to mould plastics to form, reduced the process when manufacturing, greatly reduced manufacturing cost, and mould plastics that the precision of magnetism is high, the uniformity is good, has effectively guaranteed the concentricity and the counterbalance of rotor, makes the stability of pump body during operation strengthen greatly, the noise can reduce, and make the work efficiency of the pump body to promote, is suitable for the large tracts of land and promotes.
