Abstract
The utility model discloses a screw pump rotor, be fixed in the outside nonmetal layer of skeleton including skeleton and cladding, the utility model discloses a screw pump rotor can reduce the wearing and tearing between its and the screw pump stator, increase of service life, avoid simultaneously and the stator between produce the spark, can be used to carry inflammables material, increase application scope also for adopting metal material preparation stator to create the condition, and then guarantees the heat conductivity of stator, improves the radiating effect, does benefit to the operation of screw pump safety and stability.
Description
Technical field
The utility model relates to a kind of screw pump rotor.
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 occur between its rotor and stator, serious wear, working life is short, easily occurs spark during friction, cannot carry flammable materials.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of screw pump rotor, the wearing and tearing between itself and screw pump stator can be reduced, increase the service life, avoid producing spark simultaneously between stator, can be used for carrying flammable materials, increase Applicable scope, also create condition for adopting metallic material to make stator, and then ensure the thermal conductivity of stator, improve radiating effect, be beneficial to screw pump and safely and steadily run.
Screw pump rotor of the present utility model, comprises skeleton and the non-metallic layer being coated and fixed on skeleton outside.
Further, described non-metallic layer is gum cover.
Further, described skeleton is screw rod structure and the thickness of non-metallic layer is even.
Further, described non-metallic layer is coated on periphery and the front-end face of skeleton.
Further, the rear end of described skeleton is provided with the coupling shaft that the rotating shaft along screw pump rotor extends back; The periphery of described coupling shaft is provided with keyway and anticreep groove; Described anticreep groove is evenly arranged multiple along coupling shaft excircle.
The beneficial effects of the utility model are: screw pump rotor of the present utility model, the wearing and tearing between itself and screw pump stator can be reduced, increase the service life, avoid producing spark simultaneously between stator, can be used for carrying flammable materials, increase Applicable scope, also condition is created for adopting metallic material to make stator, and then ensure the thermal conductivity of stator, improve radiating effect, be beneficial to screw pump and safely and steadily run.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model, as shown in the figure: the screw pump rotor of the present embodiment, comprise skeleton 1 and the non-metallic layer 2 being coated and fixed on skeleton 1 outside, the wearing and tearing between itself and screw pump stator can be reduced, increase the service life, avoid producing spark simultaneously between stator, can be used for carrying flammable materials, increase Applicable scope, also condition is created for adopting metallic material to make stator, and then ensure the thermal conductivity of stator, improve radiating effect, be beneficial to screw pump and safely and steadily run; Skeleton 1 outer surface is provided with the projection in multiple embedding non-metallic layer 2, increases the stabilization by consolidation between skeleton 1 and non-metallic layer 2.
In the present embodiment, described non-metallic layer 2 is gum cover, and gum cover is by having certain corrosion resistance and resistant to elevated temperatures material is made, as fluorine rubber, there is good heat resistance, oxidative stability, oil resistance, corrosion resistance and resistance to weathering, greatly improve usability and the life-span of rotor.
In the present embodiment, described skeleton 1 is screw rod structure and the thickness of non-metallic layer 2 is even, and make non-metallic layer 2 surface strength even, working life is of a specified duration, can ensure the quality of fit between itself and screw pump stator.
In the present embodiment, described non-metallic layer 2 is coated on periphery and the front-end face of skeleton 1, and make non-metallic layer 2 form the whole working surface of rotor, usability is good, and the life-span is of a specified duration.
In the present embodiment, the rear end of described skeleton 1 is provided with the coupling shaft 3 that the rotating shaft along screw pump rotor extends back; The periphery of described coupling shaft 3 is provided with keyway 4 and anticreep groove 5; Described anticreep groove 5 is evenly arranged multiple along coupling shaft 3 excircle, be convenient to rotor be connected with transmission device, and ensure the stability of linkage structure between rotor and transmission device, lock screw can be set anticreep groove 5 on transmission device on respective rotor rear end coupling shaft 3, effectively prevent rotor from coming off, ensure screw pump safe and stable operation.
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.
