Description
Technical field
The utility model relates to a kind of pump technology more particularly to a kind of screw pumps with adjustable stator.
Background technique
The stator of existing screw pump generally uses outer steel sleeve, and liner uses abrasive rubber, and rotor is rotor made of steel and plates
Hard Luo.During pump operation, friction can be generated between stator and rotor, since rotor is rigidity rotor, and stator liner is
Rubber material in turn results in stator and becomes larger with rotor engagement gap so stator rubber can be gradually worn out after long-play,
To cause liquid in screw rod pump operation largely to flow back, liquid cannot be normally beaten, stator is just needed replacing at this time, virtually increases in this way
The operating cost of equipment is added.
Utility model content
The purpose of the utility model is to provide a kind of screw pumps with adjustable stator, by the way that gap adjustment part is arranged
It can be worn after a certain period of time in liner rubber, liner rubber be promoted in circumferential through inside precession jackscrew, and then through adjusting, to subtract
Gap between small stator and rotor, anti-backflow.
To achieve the above object, the utility model provides a kind of screw pump with adjustable stator, including motor
The pump housing connecting with the motor output shaft, the motor include the shell being successively socketed from outside to inside, stator, rotor and institute
Output shaft is stated, the liner rubber for reducing gap between the stator and the rotor is equipped on the inside of the stator, it is described fixed
Gap adjustment part is provided between sub- inside and the liner rubber, the gap adjustment part includes adapting to the liner rubber
Adjusting ring, the adjusting ring includes that at least two pieces of arcs adjust index plates, and the two neighboring arc is adjusted between index plate
There are gap is adjusted, the center that the arc adjusts index plate towards the stator side is crimped with the one of locking jackscrew
The other end at end, the locking jackscrew is threadedly coupled with the stator.
Preferably, the adjusting ring includes that three pieces of arcs being evenly arranged adjust index plate.
Preferably, it is 2-3 ㎜ that the two neighboring arc, which adjusts the adjusting gap between index plate,.
Preferably, side bonds in the steel bushing for adjusting ring side and the stator.
Preferably, the material for adjusting ring is steel material.
Therefore, the screw pump with adjustable stator using the above structure of the utility model, by the way that gap is arranged
Regulating part can be worn after a certain period of time in liner rubber, and liner rubber is promoted in circumferential through inside precession jackscrew, and then through adjusting,
To reduce the gap between stator and rotor, anti-backflow.
Below by drawings and examples, the technical solution of the utility model is described in further detail.
Detailed description of the invention
Fig. 1 is a kind of motor cross-sectional view of the screw pump with adjustable stator of the embodiments of the present invention；
Fig. 2 is a kind of motor longitudinal section of the screw pump with adjustable stator of the embodiments of the present invention.
Wherein: 1, rotor；2, liner rubber；3, arc adjusts index plate；4, stator；5, jackscrew is locked.
Specific embodiment
Below with reference to attached drawing, the utility model will be further described, it should be noted that the present embodiment is with this skill
Premised on art scheme, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is not
It is limited to the present embodiment.
Fig. 1 is a kind of motor cross-sectional view of the screw pump with adjustable stator of the embodiments of the present invention, Fig. 2
For a kind of motor longitudinal section of the screw pump with adjustable stator of the embodiments of the present invention, such as Fig. 1 and Fig. 2 institute
Show, the structure of the utility model, including motor and the pump housing connecting with motor output shaft, motor includes successively being socketed from outside to inside
Shell, stator 4, rotor 1 and output shaft, the liner rubber for reducing gap between stator 4 and rotor 1 is equipped on the inside of stator 4
Glue 2 is provided with gap adjustment part between 4 inside of stator and liner rubber 2, and stator 4 is in axial direction provided at least two
The gap adjustment part, gap adjustment part include the adjusting ring adapted to liner rubber 2, and the material for adjusting ring is steel material, are adjusted
Save side bonds in the steel bushing of ring side and stator 4, then through molten rubber will adjust ring be positioned at liner rubber 2 and stator 4 it
Between, it is liner rubber 2 after above-mentioned molten rubber molding, adjusting ring includes that at least two pieces of arcs adjust index plate 3, the present embodiment
Adjusting ring include that three pieces of arcs being evenly arranged adjust index plates 3, two neighboring arc adjusts between index plate 3 that there are adjustings
Gap, it is preferred that it is 2-3 ㎜ that two neighboring arc, which adjusts the adjusting gap between index plate 3, and arc adjusts 3 direction of index plate
The center of 4 side of stator is crimped with one end of locking jackscrew 5, and the other end of locking jackscrew 5 is threadedly coupled with stator 4,
After the pump housing runs a period of time, since the friction between liner rubber 2 and rotor 1 causes liner rubber 2 to generate certain abrasion,
Then it respectively corresponds each arc of inside precession and adjusts the corresponding jackscrew of index plate 3, to reduce liner rubber 2 and rotor 1
Between gap, 4 inner cavity of stator is gradually reduced, in this way, the gap between stator 4 and rotor 1 returns to initial gap width, makes
Pump can normally beat liquid again, through test by adjusting jackscrew, 4 inner cavity of stator can be made just to need replacing after tightening 3-4 times and new determined
Son 4, so that the service life of stator 4 extends 3-4 times.Greatly reduce the operating cost of equipment.
Therefore, the screw pump with adjustable stator using the above structure of the utility model, by the way that gap is arranged
Regulating part can be worn after a certain period of time in liner rubber, and liner rubber is promoted in circumferential through inside precession jackscrew, and then through adjusting,
To reduce the gap between stator and rotor, anti-backflow.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model rather than limit it
System, although the utility model has been described in detail with reference to the preferred embodiment, those skilled in the art should manage
Solution: it still can be with the technical solution of the present invention is modified or equivalently replaced, and these are modified or equally replace
Changing also cannot make modified technical solution be detached from the spirit and scope of the technical scheme of the present invention.
