Abstract
The utility model discloses a screw pump stator, screw pump stator is for tubular structure and adopt metal material to make, the utility model discloses a screw pump stator adopts metal material to make, and the heat conductivity is good, does benefit to the heat dissipation, reduces the operating temperature of the pump body, guarantees the cooperation precision and the performance of each part, increase of service life.
Description
Technical field
The utility model relates to screw pump stator.
Background technique
Screw pump is widely used as feeder, screw pump is volume type rotor pump, it relies on the volume-variation of the Seal cage of rotor and stator formation suck and discharge material, have flow trim, pressure pulsation little, have the advantages such as suction capacity, noise are low, efficiency is high, the life-span is long, reliable operation, and do not form eddy current during fed sheet of a media, insensitive to the viscosity of medium, can transfer of highly viscous medium, existingly in the conveying of the materials such as emulsion to apply.
During screw pump work, friction phenomenon can be there is between its rotor and stator, produce large calorimetric, and the stator of screw pump generally adopts metal shell to add the structure of nonmetal inner core at present, thermal conductivity is poor, is unfavorable for heat radiation, pump body temperature is caused to raise, affect quality of fit and the usability of each parts, easily damage, working life is short.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of screw pump stator, and thermal conductivity is good, is beneficial to heat radiation, reduces the operating temperature of the pump housing, ensures quality of fit and the usability of each parts, increase the service life.
Screw pump stator of the present utility model, described screw pump stator is tubular construction and adopts metallic material to make.
Further, one end of described screw pump stator is fixed with charging flange, and the other end is fixed with discharging flange.
Further, the two ends of described screw pump stator embed in corresponding charging flange and discharging flange and are welded and fixed and seal; The interior edge face of described charging flange and discharging flange is provided with the deep gouge for embedding for screw pump stator.
Further, the exterior edge face of described charging flange is also provided with deep gouge so that connect feeding device.
The beneficial effects of the utility model are: screw pump stator of the present utility model, and adopt metallic material to make, thermal conductivity is good, is beneficial to heat radiation, reduces the operating temperature of the pump housing, ensures quality of fit and the usability of each parts, increase the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model, and as shown in the figure: the screw pump stator of the present embodiment, described screw pump stator 1 is tubular construction and adopts metallic material to make; Thermal conductivity is good, is beneficial to heat radiation, can reduce the operating temperature of the pump housing, ensures quality of fit and the usability of each parts, increases the service life; The periphery of stator is provided with the ring fin along the circumferential direction arranged, ring fin is multiple and evenly distributed along stator shaft orientation, the periphery of stator is also provided with longitudinal Heat sink vertically, longitudinal Heat sink and ring fin intersect be fixed into netted, ring fin and longitudinal Heat sink are all one-body molded with stator, significantly can not only increase the surface area of stator, improve heat dispersion, and structural strength and the rigidity of stator can be strengthened, can the thickness of stator and volume be done little, save material, weight reduction, reduces costs.
In the present embodiment, one end of described screw pump stator 1 is fixed with charging flange 2, and the other end is fixed with discharging flange 3; Stator is convenient to be connected with feeding device and conveyance conduit.
In the present embodiment, the two ends of described screw pump stator 1 embed in corresponding charging flange 2 and discharging flange 3 and are welded and fixed and seal; The interior edge face of described charging flange 2 and discharging flange 3 is provided with the deep gouge for embedding for screw pump stator 1; The end of stator is embedded in corresponding deep gouge, then be welded and fixed and seal, screw pump stator 1 and the join strength between charging flange 2 and discharging flange 3 can not only be improved, and can locate reliably stator in assembly process, improve assembly precision, charging flange 2 and discharging flange 3 can also provide radial support for stator end, ensure stator end structure stability.
In the present embodiment, the exterior edge face of described charging flange 2 is also provided with deep gouge so that connect feeding device; The discharge end of feeding device is embedded in the deep gouge of the exterior edge face of charging flange 2, then be welded and fixed and seal, the join strength between feeding device and charging flange 2 can not only be improved, and can locate reliably feeding device in assembly process, improve assembly precision.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
