Description
Technical field
This utility model is related to a kind of micropump, more particularly to a kind of micropump with injection magnet rotor.
Background technology
Existing micropump rotor is generally the coalition of the compositions such as Magnet, impeller, axle sleeve, plastics.When manufacturing, need
It is first that Magnet pre-production is good, then Magnet, plastic impeller, axle sleeve are molded together.Product Process is complicated, cost of manufacture
Height, the concentricity and aequum of rotor are difficult to ensure that, it is often necessary to which car lesser trochanter external diameter is improving balance；The Magnet of existing rotor
Sintered magnet or binding magnet are typically adopted, product surface is coarse, and precision is low, more impurity is also had in manufacturing process and is produced；
Using the micropump of such rotor, relatively costly, noise is larger, and long-term work also has the phenomenon got rusty in water, causes
Pollution.
Utility model content
This utility model is to provide a kind of micropump with injection magnet rotor, to solve to be deposited in above-mentioned background technology
Deficiency.
The technical problem solved by this utility model is realized using below scheme：
It is a kind of with injection magnet rotor micropump, including mainly by pump head, pump chamber, pump cover, motor stator, rotor, in
Heart axle, wheel member assembling constitute the pump housing, rotor be socketed on center shaft, it is characterised in that described rotor part and
The magnet component installed needed on rotor, two parts are connected using magnetic material injection moulding integrated molding, are blended in one so as to be formed
The injection magnet rotor of body.
For this utility model, described impeller is shaped in the end of injection magnet rotor.
For this utility model, described injection magnet rotor is directly socketed on the central shaft of the pump housing, or passes through injecting magnetic
In rotor round empty cavity embed dress axle sleeve be socketed on center shaft.
For this utility model, using the mode that magnetizes, preferably 4 poles and 6 polar diameters are to filling for the magnetic of described injection magnet rotor
Magnetic, but it is not limited to other modes that magnetize.
For this utility model, described axle sleeve includes but is not limited to plastic sleeve, Magnet axle sleeve, Ceramic shaft sleeve, graphite
Axle sleeve.
Beneficial effect：Requisite Magnet on rotor, rotor, and impeller are adopted magnetic material one by this utility model
Secondary property is molded, so as to pass through a Shooting Technique by three is combined together, reduce technique when manufacturing
Process, greatly reduces production cost；Meanwhile, the high precision of injecting magnetic, concordance are good, be effectively ensured the concentricity of rotor with
Aequum, stability when making the pump housing work are greatly reinforced；Magnet and impeller are same material, one between impeller and Magnet
Molding, seamless combination need not be fabricated separately Magnet and impeller, and product surface is more smooth, fine and smooth, and without step sense, rotor is at a high speed
During rotation, degree of balance is higher, and noise is relatively low；Also, the surface effect of injecting magnetic is also more smooth, fine and smooth, the pump housing is when high speed rotates
Small flow resistance so that the work efficiency of the pump housing is lifted；The material that product is used is injecting magnetic, than traditional sintering magnetic
Ferrum or binding magnet high precision, good stability, works in water the bad phenomenon such as get rusty that do not have for a long time；This utility model is adapted to
In spread.
Description of the drawings
Fig. 1 is structure sectional view of the present utility model.
In figure：1-- pump heads, 2-- pump chambers, 3-- pump covers, 4-- motor stators, 5-- central shafts, 6-- impellers, 7-- injecting magnetics
Rotor, 8-- axle sleeves.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described in detail as follows：
It is referring to shown in accompanying drawing 1, a kind of with the micropump for being molded magnet rotor, including by pump head 1, pump chamber 2, pump cover 3, motor
The pump housing that the assembling of the parts such as stator 4, rotor, central shaft 5, impeller 6 is constituted, rotor are socketed on center shaft, it is characterised in that institute
The magnet component installed needed on the rotor part stated and rotor, two parts are connected using magnetic material injection moulding integrated molding,
So as to form the injection magnet rotor 7 for being blended in one.For simplification of flowsheet, described impeller is shaped in injection magnet rotor
End.
When specifically manufacturing, injection magnet rotor can be directly socketed on the central shaft of the pump housing, it is also possible in injection
The embedded dress axle sleeve 8 of the interior round empty cavity of magnet rotor, injection magnet rotor are socketed on center shaft by axle sleeve, and the material of axle sleeve can be
Plastics, Magnet, ceramics, graphite or other materials.
Requisite Magnet on rotor of the present utility model, rotor, and impeller is using the injection of same magnetic material
One-shot forming, it is therefore an objective to improve the concordance of product, makes the concentricity and computing ballance correction of product secure, while reducing being molded into
This；For the magnetic material of rotor, only rotor the latter half can need to be magnetized using the mode that suitably magnetizes, impeller wheel portion can
Not magnetize, it is ensured that meet motor magnetic property requirements, during work, injection magnet rotor plays existing rotor simultaneously
The effect of upper magnet, magnetize mode preferably 4 poles and the 6 pole radial magnetizings of rotor, but it is not limited to other modes that magnetize；Rotor it is resistance to
Warm grade can be obtained by adjusting the temperature resistant grade of injected plastics material, can meet the use occasion of different temperatures, using height
Temperature-resistant material, the subject range of the rotor of injection then can reach more than 150 DEG C.
Advantage of the present utility model：
1st, the material that product is used is injecting magnetic, than traditional sintered magnet or binding magnet high precision, good stability, long
Phase works in water and does not have the bad phenomenon such as get rusty；
2nd, product only needs to once injection moulding, and process is simple, production efficiency are high, reduce production cost；
3rd, because being molded, product surface unusual light and exquisiteness, when high speed rotates, the resistance of liquid is little, work effect
Rate is high；
4th, Magnet and impeller are same material, are integrally formed between impeller and Magnet, seamless combination, need not be fabricated separately
Magnet and impeller, product surface are more smooth, fine and smooth, and without step sense, when rotor rotates at a high speed, degree of balance is higher, and noise is relatively low；
5th, the Magnet and rotor of this product combines together, by magnetizing, suitable magnetic field center position may be selected, passes through
Magnetic field center position, can control rotor in the maglev position of water pump, so as to reduce the friction between rotor and pad, produce
Product noise is relatively low, and efficiency is higher；Suitably magnetize mode, preferably 4 poles and 6 pole radial magnetizings are may be selected, but not limited to this magnetize
Mode；
6th, the temperature resistant grade of rotor can be obtained by adjusting the temperature resistant grade of injected plastics material, can meet different temperatures
Use occasion.Using high-temperature resistant material, the rotor of injection can reach more than 150 DEG C.
