Description
Technical field
The utility model relates to water pump fields, more particularly to a kind of pump case and pump based on 3D printing.
Background technique
In production, pump case because the strength of materials not enough due to example damage be it is few, often because of its insufficient rigidity,
Excessive deformation and unstability occurs and fails.Consequently, it is desirable to which the matter of utmost importance considered is: after pump case molding, in tensile, compressive, bending, turning round
Etc. under the external force of forms, its deformation (line deformation, angular deformation) can be reasonably resistant to and with certain mechanical stability.
In production practice, for pump case, since it is complex-shaped cambered shell, and pump case inner surface must light
Slip-stream is smooth, increases its rigidity with the two kinds of measures of shell wall thickness are increased in outer surface setting reinforcing rib so can only take.However
Both methods undoubtedly will increase weight and material cost.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of pump case based on 3D printing, light and material cost
It is low.
The technical scheme adopted by the utility model is
A kind of pump case based on 3D printing, including the internal layer, interlayer and outer layer stacked gradually, the internal layer, interlayer and outer
Layer material having the same is simultaneously connected, and the interlayer adjoins one another into honeycomb by the regular polygon that several arrays are arranged,
And cavity is surrounded between two or more regular polygons adjacent to each other.
The regular polygon is regular octahedron as a further improvement of the utility model,.
The regular polygon is solid construction as a further improvement of the utility model,.
As a further improvement of the utility model, the interlayer have multiple sequentially connected layerings, it is each layering by
The regular polygon of several array arrangements is constituted, each regular polygon arrangement direction having the same in same layering.
The regular polygon of adjacent layering mutually staggers as a further improvement of the utility model,.
In the layering being connect as a further improvement of the utility model, with internal layer, one of surface of regular polygon
Connect the internal layer.
In the layering being connect as a further improvement of the utility model, with outer layer, one of surface of regular polygon
Connect the outer layer.
The utility model also provides the pump using above-mentioned pump case, the technical solution adopted is that:
A kind of pump, the impeller including above-mentioned pump case and in pump case, the internal layer of pump case is towards impeller, the outer layer of pump case
Far from impeller towards the external world.
The beneficial effects of the utility model are: the utility model is arranged by being provided with interlayer and interlayer by regular polygon
At honeycomb, interlayer has very high rigidity thus, and rigidity is closer to for the shell of same thickness, but weight
Its relatively light material requested of amount is also less, thus brings the reduction of cost.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing.
Fig. 1 is the schematic diagram of the utility model；
Fig. 2 is the schematic diagram of interlayer.
Specific embodiment
Such as the pump case based on 3D printing of Fig. 1 and Fig. 2, including the internal layer 1, interlayer 2 and outer layer stacked gradually from the bottom to top
3.Internal layer 1, interlayer 2 and the material having the same of outer layer 3 are simultaneously connected, for example, this three layers material be engineering plastics or
Person's cast iron, this three-decker forms an entirety after its molding, and line of demarcation is not present.
Wherein, internal layer 1 and outer layer 3 are solid, and interlayer 2 is simultaneously non-solid, but the positive multi-panel arranged by several arrays
Body 21 adjoins one another into honeycomb, surrounds cavity between two or more regular polygons 21 adjacent to each other.It is this that there is sky
The material of chamber portion is omitted for solid structure in 2 structure of interlayer of chamber, thus the same thickness the case where it
Under, weight is lighter, and material is used less, and cost is also lower.In addition, since densely covered regular polygon constitutes cellular knot
Structure, this structure are similar to the crystal structure of diamond, rigidity with higher, in the outer masterpiece of the forms such as tensile, compressive, bending, torsion
Under, shell can be reasonably resistant to its deformation and with certain mechanical stability.
Above-mentioned this three-decker simultaneously has the pump case of honeycomb sandwich 2 equal by traditional casting technique or Shooting Technique
It can not be made, the pump case in embodiment can successively be printed by 3D printing technique thus.
In further preferred embodiment, regular polygon is regular octahedron.
In further preferred embodiment, regular polygon is solid construction, and solid construction is more advantageous to carrying and improves more
High rigidity.
With reference to Fig. 2, interlayer 2 has multiple sequentially connected layerings, and each layering connects from the bottom to top.Each layering is by several
The regular polygon 21 of array arrangement is constituted, each regular polygon arrangement direction having the same in same layering.In addition, adjacent point
The regular polygon of layer mutually staggers, and the regular polygon layer structure of intersecting has preferable rigidity.
In preferred embodiment, regular polygon 21 is regular octahedron, in the layering being connect with internal layer 1, regular octahedron its
In in surface connection internal layer 1 namely the layering one of surface of all regular octahedrons be all connected with internal layer 1.
Further, in the layering being connect with outer layer 3, one of surface connection outer layer 3 of regular octahedron namely the layering
In one of surfaces of all regular octahedrons be all connected with outer layer 3.
Water pump using above-mentioned pump case further includes the impeller in pump case, and impeller is simultaneously not shown, 1 direction of internal layer of pump case
Impeller and contact water body, the outer layer 3 of pump case ingress of air far from impeller and towards the external world, the interlayer 2 of pump case is by internal layer 1 and outer
Layer 3 is clamped in centre.
The above is the utility model preferred embodiment, is not constituted to scope of protection of the utility model
Limitation.
The utility model relates to a kind of pump case and pump based on 3D printing, is belonged to water pump field, in stacking gradually
Layer, interlayer and outer layer, the internal layer, interlayer and outer layer material having the same are simultaneously connected, and the interlayer is by several arrays
The regular polygon of arrangement adjoins one another into honeycomb, and surrounds sky between two or more regular polygons adjacent to each other
Chamber.The utility model is arranged in honeycomb by regular polygon by being provided with interlayer and interlayer, and interlayer has very high thus
Rigidity, rigidity is closer to for the shell of same thickness, but its material requested of lighter in weight is also less, thus
Bring the reduction of cost.
