Abstract
The utility model relates to an oil drilling is device for pump. Its technical scheme is: piston rubber passes through the cooperation of anterior bolt of piston body and clamping ring and assembles on piston body, is equipped with the leading truck at piston body's rear portion cover, is equipped with the direction ball at the tip of leading truck, the leading truck forms by the welding of adapter sleeve and ball sleeve, be equipped with a plurality of recesses of placing the ball that leads on ball sleeve. The beneficial effects are that: through the cooperation of clamping ring and bolt, can be fine compress tightly piston rubber is fixed on piston body, and piston rubber is installed easily, is dismantled, has reduced intensity of labour, is equipped with elastic gasket and can makes piston rubber laminating du genggao on the clamping ring, reduced piston rubber because of compressing tightly the damage that leads to the fact, use the leading truck to play the effect of rightting to piston body, avoided having improved the life of piston rubber because of the inclined to one side mill of piston causes wearing and tearing to piston rubber, practiced thrift the resource cost.
Description
Technical field
The utility model is related to a kind of oil drilling pump piston apparatus, particularly to a kind of oil drilling pump device.
Background technology
For now widely used drilling pump, the drilling pump of such as RL3NB series, its piston component is always along used
The traditional design gone, and piston rubber therein is consumable accessory, needs often to change in using at the scene, is additionally, since its pressure
Circle and defect present on jump ring design, in renewal part, it is desirable to have specific purpose tool dismounting and assembling, are not typically had using scene
There is specific purpose tool.Therefore on-site maintenance is extremely difficult.
Chinese patent literature Publication No. 201714656U, patent name is《A kind of wellbore pump piston of improved structure》,
There is piston body and assembling piston rubber on the piston body lead to it is characterised in that being assemblied in the anterior piston rubber of piston body
Cross trim ring and bolt is fixed on piston body.When its advantage is wellbore pump piston assembling, trim ring will be lived after being tightened by four bolts
Plug rubber compression, piston rubber is consumable accessory, and at the scene using often changeing, this structure is easily installed, dismounting.But deposit
Problem be：Piston is easy to eccentric wear in motion process, and piston rubber is consumable accessory again, when drilling pump uses not
Evitable piston rubber is caused wear and tear, accordingly, it would be desirable to using leading truck piston be carried out with righting, reduce to piston rubber
Eccentric wear.
Content of the invention
The purpose of this utility model is aiming at the drawbacks described above of prior art presence, provides a kind of oil drilling pump dress
Put, being provided with elastic sealing gasket on trim ring can make piston rubber laminating degree higher, decrease causing because of compression of piston rubber
Damage.
Its technical scheme is：Including piston main body, bolt, trim ring, piston rubber, leading truck, guiding ball, piston rubber
It is assemblied on piston main body by the cooperation of the anterior bolt of piston main body and trim ring, be arranged with guiding at the rear portion of piston main body
Frame, is provided with guiding ball in the end of leading truck, and described leading truck is welded to form by adapter sleeve and ball sleeve, on ball sleeve
It is provided with multiple grooves placing guiding ball.
The stitching surface of above-mentioned trim ring is provided with elastic sealing gasket.
The beneficial effects of the utility model are：By the cooperation of trim ring and bolt, can be very good to compress piston rubber
It is fixed on piston main body, piston rubber is easily installed, dismantled, and reduces labour intensity, elastic sealing gasket is provided with trim ring
Piston rubber laminating degree can be made higher, decrease the damage causing because of compression of piston rubber；Can be to work using leading truck
Plug main body plays the effect of righting, it is to avoid because piston eccentric wear causes to piston rubber to wear and tear, improve the use of piston rubber
In the life-span, resources costs are saved.
Brief description
Accompanying drawing 1 is structural representation of the present utility model；
Accompanying drawing 2 is the profile of A-A；
In figure：Piston main body 1, bolt 2, trim ring 3, piston rubber 4, leading truck 5, guiding ball 6, adapter sleeve 5.1, ball
Set 5.2.
Specific embodiment
In conjunction with accompanying drawing 1-2, the utility model will be further described：
The utility model includes piston main body 1, bolt 2, trim ring 3, piston rubber 4, leading truck 5, guiding ball 6, piston
Rubber 4 is assemblied on piston main body 1 by the bolt 2 of piston main body 1 front portion and the cooperation of trim ring 3, at the rear portion of piston main body 1
It is arranged with leading truck 5, be provided with guiding ball 6 in the end of leading truck 5, described leading truck 5 is by adapter sleeve 5.1 and ball sleeve
5.2 are welded to form, and are provided with multiple grooves placing guiding ball 6 on ball sleeve 5.2.
Wherein, the stitching surface of trim ring 3 is provided with elastic sealing gasket.Make neither to damage piston rubber during compression, and can be very well
Piston rubber is compressed, make the laminating degree of piston rubber higher, compression is more firm, it is to avoid because piston rubber does not compress impact
The air-tightness of piston component, in addition cause when piston does work piston rubber come off impact drilling pump service life.
The utility model passes through the cooperation of trim ring and bolt, can be very good for piston rubber to be pressed abd fixed on piston main body
On, piston rubber is easily installed, is dismantled, and reduces labour intensity, and being provided with elastic sealing gasket on trim ring can make piston rubber
Laminating degree is higher, and make that piston rubber presses is tightr, has both avoided loosening of piston rubber, decrease again piston rubber because
Compress the damage causing；Piston main body can be played with the effect of righting using leading truck, it is to avoid because piston eccentric wear is to piston
Rubber causes to wear and tear, and improves the service life of piston rubber, has saved resources costs.
The above, be only preferred embodiment of the present utility model, and any those of ordinary skill in the art all may profit
With the technical scheme of above-mentioned elaboration, the utility model is changed or be revised as equivalent technical scheme.Therefore, foundation
Any simple modification or substitute equivalents that the technical solution of the utility model is carried out, belong to the greatest extent what the utility model claimed
Scope.
