Abstract
The utility model discloses a spiral sucker rod centralizer belongs to the pipe fitting, and supporting device thereof. The technical scheme is as follows: the pipe column is cast by light and self-lubricating polymer composite materials, and a plurality of supporting tables are uniformly distributed on the outer wall of the pipe column along the circumference. Spiral diversion trenches are longitudinally arranged along the outer wall of the pipe column between the support tables. The advantages are that: reasonable design structure, light weight, wear resistance, no system damage and long service life. The rotary operation is realized, the resistance coefficient is small, and the energy conservation is facilitated.
Description
Technical field
The utility model belongs to pipe fitting, and supportive device, particularly a kind of spiral oil pumping rod centering device.
Background technology
The oil pumping rod centering device of existing oil pumper generally is the positive supported at three point part of being made by carbon steel or nylon of column.Set upright support though this structure can be used to take out,, cause energy consumption higher because its positive three-point support structure increases sucker rod resistance in service.In addition, because its raw material of selecting for use are unreasonable, coefficient of friction is big, easily causes system failure.
Summary of the invention
The purpose of this utility model is intended to overcome the deficiencies in the prior art, selects new material for use, has designed a kind of oil pumping rod centering device of novel mechanical structure.Its technical scheme is: cast tubing string with lightweight, self-lubricity polymer composite, being uniformly distributed along the circumference on the outer wall of tubing string is provided with a plurality of brace tables.Between each brace table, the spiral stream guidance groove is vertically arranged along the tubing string outer wall.
The advantage of the spiral oil pumping rod centering device of this utility model is: project organization is reasonable, light wear-resistant, no system failure, long service life.Rotating operation, resistance coefficient is little, helps energy-conservation.
Description of drawings
Figure of description is the structural representation of spiral oil pumping rod centering device of the present utility model.
Embodiment
The exemplary embodiments of spiral beam hanger centralizer of the present utility model is: the tubing string (1) of using lightweight, self-lubricity polymer composite to cast.On the outer wall of tubing string (1), being uniformly distributed along the circumference is provided with a plurality of brace tables (2), along the tubing string outer wall guiding gutter (3) is arranged vertically between each brace table (2).Brace table (2) and guiding gutter (3) are alternately to be distributed on the circumference of tubing string (1), and are the vertical one-tenth spiral along tubing string (1) outer wall.The brace table (2) and the guiding gutter (3) that have 2 groups of spiral at least have been designed on the outer wall of tubing string (1).Tubing string (1) has can intert the concentric cylindrical cavity (4) of sucker rod connector.Tubing string (1), brace table (2), guiding gutter (3) are the oil pumping rod centering devices that is cast as one.
Claims (5)
1, a kind of spiral oil pumping rod centering device, it is characterized in that being uniformly distributed along the circumference on the outer wall of a tubing string (1) is provided with a plurality of brace tables (2), along the tubing string outer wall guiding gutter (3) is arranged vertically between each brace table (2).
2, spiral oil pumping rod centering device as claimed in claim 1 is characterized in that wherein brace table (2) and guiding gutter (3) are alternately to be distributed on the circumference of tubing string (1), and is the vertical one-tenth spiral along tubing string (1) outer wall.
3, spiral oil pumping rod centering device as claimed in claim 1 or 2 is characterized in that having designed the brace table (2) and the guiding gutter (3) that have 2 groups of spiral at least on the outer wall of tubing string (1).
4, spiral oil pumping rod centering device as claimed in claim 1 or 2, it is characterized in that wherein tubing string (1) has can intert the concentric cylindrical cavity (4) of sucker rod connector.
