Abstract
The utility model relates to a petroleum mechanism, in particular to an anti-corrosion and anti-eccentric wear sucker rod joint. The technical proposal thereof is as follows: the utility model comprises a main body, internal threads and a contact layer; the main body has a cylinder-shaped structure, and the internal threads are formed on the inner walls at two ends of the main body; the contact layer is arranged on the outer wall of the main body; the internal threads are connected with a sucker rod; and the contact layer adopts an anti-corrosion and abrasion-resistant material. The utility model has the beneficial effects of convenient installation and reliable performance, and presents no safety and quality hazards without requiring additional anti-eccentric wear tools. Moreover, the utility model has the advantages of reducing the resistance to the ascending and the descending of the sucker rod, minimizing the loads of a pumping unit, and minimizing the opportunity of reducing the occurrence of the body of the sucker rod apt to buckle or hit a wall.
Description
One, technical field:
The utility model relates to a kind of petroleum machinery device, specifically is a kind of anticorrosion eccentric wear prevention pumping rod box cupling.
Two, background technology:
At present, in the mechanical oil recovery process of sucker rod pumping machine, the oil well eccentric wear is a big problem that influences the field produces cost, and various administration ways emerge in an endless stream, along with going into the well of various anti-eccentric wear instruments, news also produces thereupon, become big as the oil pumper uplink load, the descending resistance of sucker rod increases, and body is crooked is rebuffed, bear load and also strengthen thereupon, what greatly influence was recovered the oil and produced carries out smoothly.
Three, summary of the invention:
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of anticorrosion eccentric wear prevention pumping rod box cupling of easy for installation, dependable performance is provided.
Its technical scheme is: the utility model comprises main body, internal thread and contact layer, and main body is a cylindrical structure, and its two ends inwall is provided with internal thread, and the main body outer wall is provided with contact layer, and internal thread connects sucker rod, and wherein, contact layer is that corrosion and wear decreases material.
Effect of the present utility model is: easy for installation, dependable performance, no safety and hidden danger of quality more need not add any anti-eccentric wear instrument, and it is up and transfer resistance to have reduced sucker rod, alleviate the load of oil pumper, reduced the crooked phenomenon of being rebuffed of sucker rod body to greatest extent.
Four, description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Five, the specific embodiment:
With reference to accompanying drawing, the utility model comprises main body 3, internal thread 1 and contact layer 2, and main body 3 is a cylindrical structure, and its two ends inwall is provided with internal thread 1, and main body 3 outer walls are provided with contact layer 2, and internal thread 1 connects sucker rod 4, and wherein, contact layer 2 decreases material for corrosion and wear.
During use; behind the internal thread 1 two ends connection sucker rod 4 with main body 3 two ends, get final product in the lower going-into-well, when sucker rod 4 pumps; because of the maximum outside diameter of external diameter of the present utility model greater than sucker rod 4; so it at first contact with tube inner wall, contact layer 2 is a corrosion and wear damage material, when it and oil pipe relative motion; friction factor is minimum, hardness is big again; it grinds not bad oil pipe, and oil pipe does not destroy it yet, thereby reaches the purpose of protection sucker rod 4.
Claims (2)
1, anticorrosion eccentric wear prevention pumping rod box cupling comprises main body, internal thread and contact layer, it is characterized in that: main body is a cylindrical structure, and its two ends inwall is provided with internal thread, and the main body outer wall is provided with contact layer, and internal thread connects sucker rod.
2, a kind of anticorrosion eccentric wear prevention pumping rod box cupling according to claim 1 is characterized in that: contact layer is that corrosion and wear decreases material.
