Abstract
The utility model relates to a screw pump sucker rod wear-resisting centering device. The device in the utility model is mainly used for solving the problem that the traditional centering device has poor wear-resisting effect. The screw pump sucker rod wear-resisting centering device is characterized in that: two main bodies (1) in the same shape are plugged into a whole by virtue of plugging slots and plugging platforms and are slidably connected outside a nylon cover (2), the nylon cover (2) is fixed on a sucker rod, the upper end and the lower end of the nylon cover (2) are respectively provided with annular limiting platforms (3), four bosses (4) are axially arranged outside each main body (1), and a wear-resisting layer (5) made of metal powder is arranged outside each boss (4). The screw pump sucker rod wear-resisting centering device provided by the utility model has the characteristic of good wear-resisting effect.
Description
Technical field
The utility model relates to the used centralizer of oil recovery field, oil field screw bolt well sucker rod, the especially wear-resisting centralizer of screw pump sucker rod.
Background technology
In the oil recovery process of oil field,, on sucker rod, be connected with centralizer in order to prevent sucker rod partial wear.And existing centralizer exists the problem of wear-resisting weak effect owing to reasons in structure, thereby causes application life short, needs often to change, and finally increases cost for oil production, is unfavorable for applying.
Summary of the invention
In order to solve the problem of the existing wear-resisting weak effect of centralizer.The utility model provides a kind of screw pump sucker rod wear-resisting centralizer.The wear-resisting centralizer of this screw pump sucker rod has wear-resisting good effectiveness.
The technical scheme of the utility model is: the wear-resisting centralizer of this screw pump sucker rod comprises main body.Two identical shaped main bodys are pegged graft by inserting groove and grafting platform and are integral, and are slidingly connected at outside the nylon jacket, and fixedly on the sucker rod, the upper and lower side of nylon jacket has the annular stop platform respectively to nylon jacket, and main body axially has 4 boss outward, and boss has the wearing layer of metal dust outward.
The utlity model has following beneficial effect: the wear-resisting centralizer of this screw pump sucker rod is owing to two identical shaped main bodys are integral by inserting groove and the grafting of grafting platform; And be slidingly connected at outside the nylon jacket; Nylon jacket is fixedly on the sucker rod; The upper and lower side of nylon jacket has the annular stop platform respectively, and main body axially has 4 boss outward, and boss has the wearing layer of metal dust to optimize structure outward.Utilize the wearing layer of nylon jacket and metal dust to improve the wear-resisting effect of the wear-resisting centralizer of this screw pump sucker rod, and field replacement is convenient, thereby increases the service life, reduce and change number of times, finally reduce cost for oil production.The wear-resisting centralizer of this screw pump sucker rod has wear-resisting good effectiveness thus.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-main body among the figure, 2-nylon jacket, 3-annular stop platform, 4-boss, 5-wearing layer.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing, the wear-resisting centralizer of this screw pump sucker rod comprises main body 1.Two identical shaped main bodys 1 are pegged graft by inserting groove and grafting platform and are integral; And be slidingly connected at outside the nylon jacket 2, fixedly on the sucker rod, the upper and lower side of nylon jacket 2 has annular stop platform 3 respectively to nylon jacket 2; Place restrictions on main body 1 by annular stop platform 3; Prevent that main body 1 from skidding off nylon jacket 2,4 boss 4 are axially arranged outside the main body 1, the boss 4 outer wearing layers 5 that metal dust is arranged.
During actual the use:
The wear-resisting centralizer of this screw pump sucker rod not only has anti-eccentric wear and paraffin cutting effect, also has intensity height, shock-resistant, wear-resistant, high temperature resistant and corrosion resistant characteristics.
