Description

A kind of bobbin type oil pumping rod centering device structure
Technical field
This utility model relate to a kind of bobbin type oil pumping rod centering device structure, and more particularly to one kind is in down-hole sucker rod pump Can prevent sucker rod from a kind of bobbin type oil pumping rod centering device structure of eccentric wear occurring because of curvature effect during exploitation.
Background technology
During crude oil extraction, the eccentric wear problem of sucker rod is one of subject matter in the production of oil field, sucker rod Bearing own wt, bear fluid column load and flexing effect can occur when bearing pumping unit horsehead given pressure, cause Rod sag eccentric wear, reduces sucker rod service life, causes sucker rod easy fracture, well workover frequently, to take time and effort, increase out Adopt cost.For this it is proposed that a kind of bobbin type oil pumping rod centering device structure of knowing clearly, the mode being threaded connection is by sucker rod Couple together, can prevent sucker rod from bending eccentric wear, substantially increase the working life of sucker rod in underground mining.
The content of the invention
This utility model passes through problem above, there is provided a kind of a kind of bobbin type oil pumping rod centering device knot of simple structure Structure, and spin is designed, make spin reduce friction in the way of ball is contacted with oil pipe, the compression spring being connected with spin can make Spin has certain gap adjustment space, makes simple structure, safe and reliable.
It is to reach above-mentioned purpose the technical solution adopted in the present invention:Including sucker rod, centralizer body, screw, oil stream Hole, spin set, compression spring, spin, described sucker rod connection centralizer body, centralizer body connecting screw hole, oily discharge orifice connection Centralizer body, spin set is connected with centralizer body, and spin is connected by compression spring with spin set.
On the basis of above-mentioned technical proposal, a kind of bobbin type oil pumping rod centering device structure, spin set is connected with centralizer body, Spin is connected by compression spring with spin set.
This bobbin type oil pumping rod centering device simple structure, easy to use, good seal, applicability is high, is capable of achieving to prevent The bending eccentric wear problem that sucker rod is produced in exploitation work.

Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail with example:
As shown in figure 1, a kind of bobbin type oil pumping rod centering device structure, including sucker rod (1), centralizer body (2), screw (3), oily discharge orifice (4), spin set (5), compression spring (6), spin (7), described sucker rod (1) connection centralizer body (2) is helped Positive device body (2) connecting screw hole (3), oily discharge orifice (4) connection centralizer body (2), spin set (5) is connected with centralizer body (2), spin (7) it is connected with spin set (5) by compression spring (6).Based on the righting function of centralizer, between centralizer body (2) surrounding etc. Away from connection spin set (5), spin set (5) is connected by compression spring (6) with spin (7), and spin (7) is contacted and oil pipe by ball Wall connects, and four spin (7) are equidistantly arranged, and strengthen the stability of sucker rod (1), prevents sucker rod (1) from flexing effect occurring Should, bend eccentric wear.
Preferably, described a kind of bobbin type oil pumping rod centering device structure, it is characterised in that:Described spin set (5) with Centralizer body (2) connects, and spin (7) is connected by compression spring (6) with spin set (5).
This utility model has redesigned a kind of a kind of bobbin type oil pumping of simple structure through careful research and discussion Bar centralizer structure, and spin is designed, make spin reduce friction in the way of ball is contacted with oil pipe, the compression being connected with spin Spring can make spin have certain gap adjustment space so that this simple structure is safe and reliable, and ensures oil-producing in structure It is unimpeded in passage, can better and safer production, extend sucker rod working life, reduce oil well maintenance cost.
Above this utility model is illustrated by way of example, but this utility model is not limited to above-mentioned being embodied as Example, all any changes done based on this utility model or modification belong to the claimed scope of this utility model.
