Abstract
The utility model discloses a shielding sleeve, which relates to an improvement to a shielding sleeve structure of a shielding electric pump. The utility model provides the shielding sleeve which can enhance the efficiency of the shielding type motor. The utility model comprises a shielding sleeve, the utility model has the structural key points that the middle of the shielding sleeve is made of magnetic conductive material corresponding to a rotor iron core or a stator iron core, and the non-magnetic conductive material is arranged outside the middle magnetic conductive material of the shielding sleeve.
Description
Technical field:
The utility model relates to the improvement of the shield cover structure of shielded electric pump.
Background technology:
Shielded electric pump is to be combined by protected type motor and pump.Stator can, the rotor shielding sleeve of protected type motor normally are made of non-magnet_conductible material, make that the effective non-magnetic conduction gap between stator and the rotor is strengthened, and reach the several times of common motor air gap; Cause the electric pump power consumption to increase, efficient is than much lower with the common motor of number of poles with power, and power factor is then lower.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of housing that improves the protected type motor efficiency is provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises housing, and its structural feature is that the centre of housing is the permeability magnetic material corresponding to rotor core or stator core, and the middle permeability magnetic material of housing is outward a non-magnet material.
The beneficial effects of the utility model:
Because the centre of housing of the present utility model is the permeability magnetic material corresponding to rotor core or stator core, the middle permeability magnetic material of housing is outward a non-magnet material; Effective non-magnetic conduction gap between stator and the rotor is significantly reduced, can accomplish identical with the air gap of common motor; The efficient and the power factor of protected type motor are greatly improved.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the instance graph that housing of the present utility model is applied to the protected type motor.
Embodiment:
The utility model comprises housing 1, and the centre of housing 1 is the permeability magnetic material part 2 corresponding to rotor 5 iron cores or stator 6 iron cores, is non-magnet material part 3 outside the middle permeability magnetic material part 2 of housing 1.
The thickness of housing 1 can be 0.5 millimeter.
Housing 1 of the present utility model both can be used as the stator can 1 of protected type motor 4, also can be used as the rotor shielding sleeve 1 of protected type motor 4.
Shielded electric pump comprises pump 9, protected type motor 4, between the axle 8 of protected type motor 4 and the housing 7 is stator 6, rotor 5, stator 6, the rotor 5 outer housings 1 that are respectively arranged with, stator 6 iron cores, rotor 5 iron cores are corresponding with the middle permeability magnetic material part 2 of housing 1 respectively, are non-magnet material part 3 outside the middle permeability magnetic material part 2 of housing 1.
Claims (2)
1, a kind of housing, comprise housing (1), the centre that it is characterized in that housing (1) is non-magnet material part (3) for corresponding to rotor (5) iron core or stator (6) permeability magnetic material part (2) unshakable in one's determination outside the middle permeability magnetic material part (2) of housing (1).
2, a kind of housing according to claim 1, the thickness that it is characterized in that housing (1) is 0.5 millimeter.
