Abstract
The utility model provides a novel single-screw pump, comprising a stator. A rotor is arranged in the stator. The utility model is characterized in that the stator is cylindrical, and the inner wall is a smooth surface. The rotor is provided with a helical groove around the periphery of the outer wall of the rotor, and the section of the groove is in a U shape. The inner wall of the stator of the single-screw pump is not provided with a lining rubber layer and is the smooth surface; and only if a gap is arranged between the rotor and the inner wall of the stator, the rotor can rotate. The rotor does not touch the inner wall of the stator in rotating, and the stator can not be abraded, so the stator is not replaced regularly. The maintenance costs are reduced, and the production is not stopped as the stator is replaced. Meanwhile, as the lining rubber layer is not arranged, the rotor rotation can not generate lining rubber grains, and the conveyed liquid medium is not polluted. Thus, the single-screw pump is suitable for conveying liquid medium with cleanliness requirements, such as medicines, foods, and the like.
Description
Technical field
The utility model is specifically related to a kind of new type single screw pump.
Background technique
Eccentric rotor formula helical rotor pump includes rotor and stator, it is 180 ° Seal cage that stator and rotor form phase angle, and with the line with rubber layer, and line with rubber layer and rotor are meshing with each other on the stator inner wall, rotor rotates along the line with rubber layer, along with the fed sheet of a media purpose is finished in the rotation of rotor.But the defective of this kind helical rotor pump maximum is the line with rubber in the stator very easily weares and teares, and not only needs frequent replacing, causes the significantly increase of regular stopping production of enterprise and maintenance expenses, and can not carry the liquid that cleanliness is had requirement.
Summary of the invention
The utility model provides a kind of new type single screw pump, and purpose is to solve existing issue, provides a kind of stator can not produce wearing and tearing, can carry the helical rotor pump that cleanliness is had the liquid of requirement simultaneously.
The utility model technological scheme that adopts of dealing with problems is:
The new type single screw pump includes stator, and rotor is located in the stator, it is characterized in that: described stator is a tubular, and inwall is a smooth surface, is provided with helical groove around its outer wall periphery on the rotor.
The cross section of described groove is a U-shaped.
The beneficial effects of the utility model: do not have the line with rubber layer on the stator inner wall of this helical rotor pump, be smooth surface, rotor for can rotate then must and stator inner wall between have certain interval, rotor does not contact with stator inner wall when rotated, can not make stator produce wearing and tearing, therefore do not need often to change stator, not only reduced maintenance expenses, nor can cause stopping production because of changing stator.Simultaneously owing to there is not the line with rubber layer, rotor rotation can not produce the line with rubber particle yet, just can not pollute carrying liquid medium to produce, so this single-volute pump is applicable to that conveying has the liquid medium of requirement to cleanliness, as medicine, food etc.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of rotor.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
New type single screw pump as shown in fig. 1 includes stator 1, and rotor 2 is located in the stator 1.Described stator 1 is a tubular, and inwall is a smooth surface, is provided with helical groove 3 around its outer wall periphery on the rotor 2.As shown in Figure 2, the cross section of described groove 3 is a U-shaped.The cross section of its further groove 3 can also be other shape, as V-arrangement except U-shaped.
There is not the line with rubber layer on the stator inner wall of this helical rotor pump, be smooth surface, rotor 2 for can rotate then must and stator inner wall between have certain interval, rotor does not contact with stator inner wall when rotated, can not make stator produce wearing and tearing, therefore do not need often to change stator, not only reduced maintenance expenses, nor can cause stopping production because of changing stator.Simultaneously owing to there is not the line with rubber layer, rotor rotation can not produce the line with rubber particle yet, just can not pollute carrying liquid medium to produce, so this single-volute pump is applicable to that conveying has the liquid medium of requirement to cleanliness, as medicine, food etc.
