Description
Technical field
This utility model is related to the instrument that a kind of reduction oil pipe and sucker rod mutually wear and tear, and in particular to a kind of oil pipe is wear-resistant
Anti-attrition device.
Background technology
In oil extraction system, rod string pumps with the draw of oil pumper in tubing string, because of fitness machine
The friction that certainly exists between rod tube is managed, formation eccentric wear, particularly inclined shaft, directional well, horizontal well are especially prominent；Side-abrasion of rod string shape
Cheng Hou, causes a series of problems, such as increase of ground installation load, oil pipe are worn out, rod string is disconnected de-, reduces tar productivity, increase
Production cost.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided one kind can reduce side-abrasion of rod string, increases oil
Pipe and rod string use the oil pipe antiwear and reducing friction device of life.
The technical solution of the utility model is：
Oil pipe antiwear and reducing friction device, it is characterised in that including body and anti-attrition set, the body is tubular body, body two
End is symmetrically provided with female thread, and the external diameter that the body outer wall is divided into epimere, stage casing and hypomere, stage casing and hypomere is identical and less than upper
Section external diameter, hypomere are provided with external screw thread, and anti-attrition set is enclosed within outside stage casing, and hypomere is connected by external screw thread and end are stifled to fix anti-attrition set；
The stifled surfaces externally and internally of the body and end is processed using the anticorrosion process of nickel phosphor plating；Anti-attrition set outer wall is made up of some cambered surfaces, cambered surface
Between by round-corner transition, anti-attrition set outer wall is covered with alloy-layer.
The anti-attrition set is made up of stainless steel material, and anti-attrition set outer wall is made up of in prismatic three cambered surfaces, cambered surface radius
It is identical with tube inner wall.
This utility model is directly connected between two sucker rods and substitutes rod collar, with more preferable guide effect,
The oil flow channel between rod tube can be ensured, the abrasion of oil pipe in friction subsystem is reduced, played a part of to protect oil pipe, realize drop
Low side-abrasion of rod string, increases the purpose of tube rod service life.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of anti-attrition set.
1 body, 2 anti-attrition covers 3 ends and blocks up 4 female thread, 5 cambered surface, 6 fillet.
Specific embodiment
Oil pipe antiwear and reducing friction device, including body and anti-attrition set, the body are tubular body, and body two ends are symmetrically provided with interior
Screw thread, for connecting with pumping rod, the external diameter that the body outer wall is divided into epimere, stage casing and hypomere, stage casing and hypomere is identical and little
In epimere external diameter, hypomere is provided with external screw thread, and anti-attrition set is enclosed within outside stage casing, and anti-attrition set is rotatable, when anti-attrition set is sent out with tube inner wall
During raw mill sassafras, rotary sliding friction is covered for rolling friction by anti-attrition, more effectively protects oil pipe, hypomere by external screw thread with
The stifled connection in end is spacing to carry out to anti-attrition set, and the stifled surfaces externally and internally of body and end is processed using the anticorrosion process of nickel phosphor plating.
The anti-attrition set is made up of stainless steel material, and anti-attrition set outer wall is made up of in prismatic three cambered surfaces, prismatic knot
Structure reduces cross-sectional area itself, it is ensured that the oil flow channel between rod tube, by round-corner transition between cambered surface, anti-attrition during work
Set fillet can play more preferable guide effect, and cambered surface radius are identical with tube inner wall, and so in wear process, two faces can
Fit well, reduce the abrasion of oil pipe in friction subsystem, play a part of to protect oil pipe, anti-attrition set outer wall to be covered with alloy
Layer, through fine-grinding and polishing, 0.4 μm of surface roughness, with relatively low coefficient of friction, the eccentric wear of itself and oil pipe is damaged and is dropped significantly
It is low.
During work, oil pipe antiwear and reducing friction device pumps with oil pumper and rod string, when in device with oil pipe
When wall contact occurs friction, anti-attrition covers big cambered surface design and effectively avoids tube inner wall linear friction, while radial direction moment of torsion is produced
After life, anti-attrition set can be rotated on body, become slip and rubbed sassafras into pivoting friction, and anti-attrition covers high surface roughness, it is ensured that anti-attrition
Little coefficient of friction between set and oil pipe, the above ensure the purpose for realizing antiwear and reducing friction item by item.
Finally it should be noted that:Above example is only to illustrate the technical solution of the utility model rather than which is limited
System；Although being described in detail to this utility model with reference to preferred embodiment, those of ordinary skill in the art should
Understand：Still specific embodiment of the present utility model can be modified or equivalent is carried out to some technical characteristics and replace
Change；Without deviating from the spirit of technical solutions of the utility model, which all should cover the technical scheme being claimed in this utility model
In the middle of scope.
