Abstract
The utility model relates to a ball type sucker rod centralizer, which comprises a metal hinge matching with a sucker rod and a jacket made of superhigh molecule polymer abrasion-proof alloy, the joint of the metal hinge and a jacket is arranged into a wedge clip structure, the jacket surface is provided with a plurality of guide ribs, the guide ribs are provided with a plurality of balls, the jacket surface can also be provided with a plurality of guide grooves, the guide grooves and the guide ribs are alternately arranged, a plurality of guide grooves are arranged on both ends of jacket, the guide groove is spiral or vertical, which overcomes existing problems of sucker rod centralizer, the utility model has the advantages of nonpolar jacket, no oleophilic wax deposit, light weight, small frictional resistance, low wear, short service life, substance resource saving, low production cost etc.
Description
Technical field
The utility model relates to a kind of being fixed on the sucker rod, with the centralizer that keeps sucker rod can move between two parties in oil pipe.
Background technology
At present, in pumpingh well, the problem ubiquity of eccentric wear between sucker rod and the oil pipe, it is the degree difference of eccentric wear, sucker rod knot hoop position is particularly outstanding, it moves back and forth in oil pipe all the year round, constantly wearing and tearing, on some inclined shafts, the sucker rod knot hoop that has lost efficacy because of eccentric wear, tubing wall is worn through, existing oil pumping rod centering device, mainly contain the hinge plug-in, short connection type, swimming types etc. are several, common hinge plug-in centralizer mainly comprises and being used for and the metal hinge of sucker rod secure fit and the overcoat of being made by wear-resistant material, as Fig. 3, shown in Figure 4, metal hinge comprises upper hinge 6 and following hinge 61, and outer sleeve body comprises last overcoat 7 and the following overcoat 71 that cooperatively interacts, upper hinge 6 and following hinge 61 cooperate with last overcoat 7 and following overcoat 71 clampings respectively, outer sleeve body is provided with leads rib, and metal hinge plays embraces the effect that clamping is decided sucker rod, overcoat and oil pipe sliding friction, frictional resistance is big, anti-friction material mainly is engineering plastics such as polyurethane or nylon, the easy oleophylic wax deposition of anti-friction material, and the outer sleeve body quality of materials is heavier, wear away bigger, application life is short, needs were changed once in general three months, caused the physical resources waste, the cost of production height.
The utility model content
In order to overcome the above-mentioned technological deficiency that prior art exists, the utility model provides a kind of ball-type oil pumping rod centering device, and its advantage is that outer sleeve body is nonpolar, be difficult for the oleophylic wax deposition, lighter weight, frictional resistance is little, and the material abrasion are low, long service life is saved physical resources, and cost of production is low.
The utility model realizes that the technical scheme of above-mentioned purpose is, the utility model provides a kind of ball-type oil pumping rod centering device, comprise and being used for and the metal hinge of sucker rod secure fit and the outer sleeve body of making by supra polymer polymer antifriction alloy, described metal hinge and described outer sleeve body cooperatively interact, described outer sleeve body appearance is provided with some ribs of leading, and described some ribs of leading are provided with plurality of balls.
The beneficial effects of the utility model are: made by supra polymer polymer antifriction alloy owing to constitute the outer sleeve body of a centralizer part, supra polymer polymer antifriction alloy belongs to non-polar material, its abrasion resistance is 10 times of nylon, there is not affinity with a lot of working medias, superperformance with the anti-wax deposition of vegetables oil, lighter weight, leading of outer sleeve body is provided with plurality of balls on the rib, lead rib and oil pipe becomes rolling friction by sliding friction, frictional resistance is little, wears away lowly, prolongs outer sleeve body application life, save physical resources, cost of production reduces.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 looks schematic diagram with the corresponding left side of Fig. 1;
Fig. 3 is the schematic diagram that prior art upper hinge 6 and last overcoat 7 cooperatively interact;
Fig. 4 is the schematic diagram that hinge 61 and following overcoat 71 cooperatively interact under the prior art.
The specific embodiment
Is that example is illustrated the utility model below in conjunction with accompanying drawing with the plug-in centralizer.
Referring to Fig. 1, Fig. 2, the ball-type oil pumping rod centering device that the utility model provides, comprise and being used for and the metal hinge 1 of sucker rod secure fit and the outer sleeve body of making by supra polymer polymer antifriction alloy 2, described metal hinge 1 and described outer sleeve body 2 cooperatively interact, described outer sleeve body 2 appearances are provided with some ribs 3 of leading, and the described rib of leading is provided with plurality of balls 4.
Described plurality of balls 4 can be arranged to a row along the main direction of leading rib.Be provided with row's ball on the rib owing to lead, make the friction between outer sleeve body and oil pipe become rolling friction, reduce frictional resistance by sliding friction, wear away low, prolongation outer sleeve body application life.
Described plurality of balls 4 can be steel ball or the ball of being made by supra polymer polymer antifriction alloy or the ball of other any suitable materials.
Described outer sleeve body 2 can be set on the described metal hinge 1.
The wedge shape edge card structure that the position that described metal hinge 1 and described outer sleeve body 2 combine can be arranged to cooperatively interact.Realize the purpose that metal hinge and outer sleeve body are combined as a whole securely with this, because supra polymer polymer antifriction alloy and any material affinity not.
The mode that cooperatively interacts that described metal hinge 1 and described outer sleeve body 2 can also adopt the prior art of other any suitable to realize.
Described outer sleeve body 1 appearance can also be provided with some guiding gutters 5, and described some guiding gutters and described some rib spaces of leading are provided with.
Described outer sleeve body 1 appearance two ends can be provided with some guiding gutters.
Described guiding gutter 5 can be a helical form or vertical.
Certainly; after amplifying, this ball-type oil pumping rod centering device also can be fixed on the oil pipe outside, as becoming the ball-type tubing centrilizer, to solve down oil pipe and the wearing and tearing of internal surface of sleeve pipe moral in the oil pipe operation; thereby the protective casing inside coating is further expanded its scope of application not by breakage.
