Abstract
The invention discloses a high-performance sucker rod sealing ring, which comprises a wear-resisting ring and an elastic ring, wherein the outer part of the elastic ring is sleeved with the wear-resisting ring, an inner ring of the wear-resisting ring is provided with a convex strip, an outer ring of the elastic ring is provided with a groove, the convex strip and the groove are in interference fit to ensure the stability when the wear-resisting ring and the elastic ring are sleeved together, and viscose can also be used between the wear-resisting ring and the elastic ring for improving the bond strength and the sealing performance. The invention discloses the high-performance sucker rod sealing ring which has a special structure, the design of a double-layer structure of the wear-resisting ring and the elastic ring is used by the main body, the bond strength of the wear-resisting ring and the elastic ring is high, the composition performance is good, both the oil seal performance and the wear-resisting property of the sealing ring can be considered, and the high-performance sucker rod sealing ring has a practical value.
Description
Technical field
The present invention relates to a kind of sucker rod sealing ring, relate in particular to the high-performance pumping rod seal circle of a kind of anti-wear performance and oil sealing function admirable, belong to oil accessory technical field.
Background technology
Mechanical oil recovery is the main mode that the oil exploitation industry is recovered the oil.Along with international and domestic oil industry rapid development, the mechanical oil production technology technology has had significant progress, and the supporting level of technical equipment improves constantly, and has formed four kinds of oil recovery forms such as sucker rod pump, water conservancy piston pump, submersible electric pump and air pump.Wherein, sucker rod pumping is to be that master's rod pumping system is realized with sucker rod, oil pumper and oil well pump.Under oil pumper drove, sucker rod drove oil pump plunger piston and pumps, and fluid is evacuated to ground.In sucker rod moves up and down process, can take a certain amount of crude oil out of, cause waste.Therefore, people can be provided with black box on sucker rod, prevent the leakage of crude oil.
Usually, often between sucker rod and the sealing ring adopt the bigger cooperation of the magnitude of interference improving its sealing performance, but aggravate the loss of sealing ring easily, reduce its application life, often changing sealing ring then can influence the efficient that oil-recovery operations is produced.Therefore, when improving sealing ring oil sealing performance, how guaranteeing its good abrasion resistance and application life, is the problem that people study for a long time.
Summary of the invention
To the demand, the invention provides a kind of high-performance pumping rod seal circle, the sealing circle adopts wear-resisting circle and the design of elastic ring double-decker, when guaranteeing the good oil sealing performance of sealing ring, has taken into account anti-wear performance, makes its application life more lasting.
The present invention is a kind of high-performance pumping rod seal circle; The sealing circle comprises wear-resisting circle and elastic ring; Described wear-resisting circle snare is in the outside of elastic ring, and the inner ring of described wear-resisting circle is provided with raised line, and the outer ring of elastic ring is provided with groove; Adopt interference fit between described raised line and the groove, adopt viscose between described wear-resisting circle and the elastic ring.
In the present invention's one preferred embodiment, the cross sectional shape of described cord tissue is the isosceles trapezoid after turning on one's side, and its top margin relies on the inboard of wear-resisting circle.
In the present invention's one preferred embodiment, the shape and size of described groove structure are all similar with above-mentioned cord tissue.
In the present invention's one preferred embodiment, the material of described wear-resisting circle is selected PU or PTFE for use.
In the present invention's one preferred embodiment, the material of described elastic ring is selected ACM for use.
In the present invention's one preferred embodiment, the viscose that adopts when described wear-resisting circle and elastic ring combine is AB glue or instant glue.
The present invention has disclosed a kind of high-performance pumping rod seal circle, and the sealing coil structures is unique, and its main body adopts wear-resisting circle and the design of elastic ring double-decker; Both bond strengths are high; Composite performance is good, makes the oil sealing performance of sealing ring and anti-wear performance be able to take into account, according to practical value.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation:
Fig. 1 is an embodiment of the invention high-performance pumping rod seal coil structures sketch map;
The mark of each parts is following in the accompanying drawing: 1, wear-resisting circle, 2, elastic ring, 3, raised line, 4, groove, 5, viscose.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
Fig. 1 is an embodiment of the invention high-performance pumping rod seal coil structures sketch map; The sealing circle comprises wear-resisting circle 1 and elastic ring 2; Described wear-resisting circle 1 snare is in the outside of elastic ring 2; The inner ring of described wear-resisting circle 1 is provided with raised line 3, and the outer ring of elastic ring 2 is provided with groove 4, adopts interference fit between described raised line 3 and the groove 4; Guarantee the stability when wear-resisting circle 1 and elastic ring 2 snares are together, also can adopt viscose 5 to improve bond strength and sealing performancies between described wear-resisting circle 1 and the elastic ring 2.
The isosceles trapezoid of the cross sectional shape of raised line 3 structures of the high-performance pumping rod seal circle of mentioning among the present invention after for rollover, its top margin relies on the inboard of wear-resisting circle, this structure help wear-resisting circle 1 installation and with the cooperating of elastic ring 2; The shape and size of groove 4 structures all with above-mentioned raised line 3 structural similarities.
The material of wear-resisting circle 1 is generally selected PU or PTFE for use, selects for use this kind material to make wear-resisting circle 1 and has good mechanical performance, and wear-resisting, high-voltage resistance capability is all because other rubber seal, and the performance aspect ageing-resistant, anti-ozone and oil resistant is also very excellent; The material of elastic ring 2 is generally selected ACM for use; 2 pairs of oils of elastic ring of selecting for use this kind material to make have good resistance; High temperature resistant, the weatherability tool is good; Micro-compressive strain can occur during use, this compressive strain helps improving the dynamics that contacts of wear-resisting circle 1 and oil pipe tube wall, improves the sealing performance of sealing ring; The viscose 5 that wear-resisting circle 1 adopts when combining with elastic ring 2 is AB glue or instant glue.
The present invention has disclosed a kind of high-performance pumping rod seal circle, is characterized in: the sealing coil structures is unique, and its main body adopts wear-resisting circle and the design of elastic ring double-decker; Both bond strengths are high; Composite performance is good, makes the oil sealing performance of sealing ring and anti-wear performance be able to take into account, according to practical value.
The above; Be merely the specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
