Abstract
The utility model relates to the structure improvement of the aquatic animals water pump, comprising a plastic core and a magnet. Wherein, the magnet is provided with a plastic sealing layer at the outer surface, while a stainless steel sleeve is arranged at the outer wall of the plastic sealing layer. Due to the stainless steel sleeve at the outer wall of the plastic sealing layer adopted by the aquatic animals water pump rotor, the utility model can improve the rotor repellence to the friction and impact with the impurity such as the sand in the water, which is not easy to break and suffer abrasion, and meanwhile, the magnet made of the rear earth material is not easy to be oxidated and rusted, thereby prolonging the rotor service life; and simultaneity, the plastic sealing layer is arranged between the magnet and the stainless steel sleeve, the rotor is easy to make, ensuring easy quality control.
Description
Affiliated technical field
The utility model relates to a kind of architecture advances of water pump, relates in particular to the architecture advances of water pump rotor in a kind of Shui nationality field.
Background technique
At present, the material that general rotor adopts is a ferrite, and the defective of its existence is that magnetic intensity is less, and mechanical efficiency is low.The patent No. is the patent of ZL02226502.3, adopted rareearth magnetic material, electric current and the consumed power of using this material to make the motor of rotor all decline to a great extent, reached energy-efficient purpose, but its rotor surface adopts plastic wrappage encapsulation, in the using process plastic wrappage often with water in impurity such as the grains of sand produce friction and clash into, break easily and wear and tear, the easy oxidation and rusting of the magnet that makes rare earth material make, the working life of shortening rotor.
Summary of the invention
At the existing problem of above-mentioned technology, the purpose of this utility model provides and a kind ofly can solve waterproof, antirust, anticorrosion, can increase wear resistance and impact resistance simultaneously, make Immersible pump in aquarium rotor simple, system easy to control the quality.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of water pump rotor, and comprise and mould core, magnet, the outer surface of magnet is provided with a plastics seal, and plastics seal outer wall is provided with a stainless steel sleeve.
The beneficial effects of the utility model are: the stainless steel sleeve of plastics seal outer wall can significantly improve the repellence of rotor to friction of impurity such as the grains of sand in the water and bump, be not easy to break and wear and tear, the magnet that makes rare earth material make is difficult for oxidation and rusting, prolong the working life of rotor, simultaneously, the plastics seal is arranged between magnet and the stainless steel sleeve, makes simple, the easy to control the quality system of rotor manufacturing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation reference drawing of the present utility model;
Fig. 2 is that structure of the present utility model splits reference view.
Among the figure 1, mould core, 2, magnet, 3, ceramic ring, 4, the plastics seal, 5, stainless steel sleeve, 6, waterleaf, 7, axis.
Embodiment
As shown in Figure 1, 2, Immersible pump in aquarium rotor of the present utility model comprises and moulds core 1, magnet 2, the rotor shaft hatch two ends are provided with ceramic ring 3, magnet 2 is rare earth magnetic (NdFeB material), and the outer surface of magnet 2 is provided with a plastics seal 4, and the outer wall of plastics seal 4 is provided with a stainless steel sleeve 5.
Magnet 2 and external environment that plastics seal 4 of the present utility model can be made rare earth material separate, stainless steel sleeve can significantly improve the repellence of rotor to friction of impurity such as the grains of sand in the water and bump simultaneously, be not easy to break and wear and tear, make magnet waterproof, anticorrosion, anti-oxidation the getting rusty that rare earth material is made, prolong the working life of rotor; In addition, the plastics seal is arranged between magnet and the stainless steel sleeve, makes simple, the easy to control the quality system of rotor manufacturing.During use, rotor rotates around axis 7 under magnetic force, and waterleaf 6 rotates; Axis 7 is a porcelain shaft, the use that matches with the ceramic ring 3 at rotor shaft hatch two ends, the working life that can greatly improve rotor.
