Brief description of the drawings
Fig. 1 is the structural representation of the utility model high-speed magnetic pump.
Wherein: 1-interior magnet rotor; 2-outer magnet rotor; 3-shielding can; 4-magnetic field modulation ring; 5-magnetic inductive block; 6-non-magnetic; 7-high speed internal magnetic ring; 8-low speed outer magnetic ring.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but this is not to restriction of the present utility model, those skilled in the art are according to basic thought of the present utility model, can make various amendments or improvement, but only otherwise depart from basic thought of the present utility model, all within scope of the present utility model.
High-speed magnetic pump of the present utility model, mainly comprise: interior magnet rotor 1, outer magnet rotor 2, shielding can 3 and be located at the magnetic field modulation ring 4 on shielding can 3, wherein, magnetic field modulation ring 4 is assembled into one with shielding can 3 and (comprises embedding shielding can, is close to shielding can outer wall etc., preferably adopt 3D printing technique to make an entirety), this magnetic field modulation ring 4 is by magnetic inductive block 5 and non-magnetic 6 processing, combination, assembling all-in-one-piece, magnetic inductive block 5 and the non-magnetic 6 excircle direction along shielding can 3 are radially, staggered, spaced.The outside of interior magnet rotor 1 is for having the high speed internal magnetic ring 7 of less magnetic pole (being the N utmost point and the S utmost point of usually said magnetic patch), the inner side of outer magnet rotor 2 is the low speed outer magnetic ring 8 with more magnetic pole, and magnetic field modulation ring 4 is between high speed internal magnetic ring 7 and low speed outer magnetic ring 8.
High speed internal magnetic ring 7 and low speed outer magnetic ring 8 rearrange by magnetic patch, wherein said magnetic patch both can be by the N utmost point and S utmost point even number alternately, as N--S, S--N, and N--S, S--N......, such magnetic pole distributes, and to be suitable for outer magnetic patch be even number value; Also can be along the circumferential direction in turn, uniform arrangement, as N--S, N--S, N--S, N--S......, such magnetic pole distributes, and to be suitable for outer magnetic patch be odd number value.Odd number or even number are decided by required gear ratio design.
In the utility model, magnetic inductive block 5 is made up of permeability magnetic material, is made up for non-magnetic 6 of non-magnet material.
