Abstract
The utility model relates to an oil pumping rod oil stripper, belonging to the movable sealing technology of an oil pumping rod on an oil field oil pumping device. The oil pumping rod oil stripper is assembled by connecting an installation guide sleeve (1), an obturating ring (2), an upper press cover (3), oil stripping plates (4), springs (5), a connecting sleeve (6) and a core rack (7). Crude oil which adheres to the oil pumping rod when running is stripped by arranging a plurality of oil stripping plates which are staggered, stratified and separate and are tightly pressed by the springs. The oil stripping plates and the springs are arranged on a rectangular hole of the core rack; the core rack is arranged on an inner cavity of the connecting sleeve; and the lower end of the connecting sleeve forms a screwed connection with an oil well port, and the upper end forms a screwed connection with the upper press cover. The obturating ring is arranged between the core rack and the upper press cover for sealing; and the installation guide sleeve is a special auxiliary piece for field installation. The oil pumping rod oil stripper has simple structure and convenient installation, has self-compensation action to installation error of the oil pumping rod, reduces camber wear and running resistance of the oil pumping rod, can greatly prolong the service life, saves the maintenance cost, and reduces the environment pollution.
Description
One, technical field:
The utility model relates to the dynamic sealing technology of oil recovery industry oil pumper equipment, especially the dynamic sealing technology of sucker rod on the oil pumper equipment.
Two, background technology:
For a long time, the sucker rod on the oil-field oil pumper equipment is in operation, because former seal failure, crude oil is taken out of by sucker rod, causes the phenomenon of leakage very common, and this has not only increased maintenance cost, and environment has also been caused pollution.Though also there is the sucker rod sealing device of various ways using at present, but effect is not too desirable, there is the improved place of many needs, mainly be that seal durability is short, change frequently, especially when sucker rod position installation deviation is big, the eccentric wear phenomenon is very serious, this has not only strengthened the running resistance of sucker rod, and seal was lost efficacy with regard to eccentric wear in the not long-time back of work, causes leakage pollution.
Three, summary of the invention:
The problem that the utility model exists at existing sucker rod sealing device, adopt staggered layering, deviation compensation, the method of Follow-up seal, overcome the technical deficiency of existing improvement, the technical solution adopted in the utility model is: staggered layering, several oil scraping plates of independent, spring compression separately are set, sucker rod is scraped off upwards moving the crude oil that adheres on the king-rod, the crude oil that scrapes is by in the inner water conservancy diversion slit flow oil return well.Oil scraping plate is arranging of independent, staggered layering separately, can clean out the crude oil that adheres on the sucker rod fully at many levels; Adopt oil scraping plate mode separate, spring compression both can ensure that oil scraping plate closely was fitted on the sucker rod all the time, utilize the elastic force of spring can also make oil scraping plate that certain regulated quantity is arranged in radial position simultaneously, even there is the alignment error of sucker rod, the deviation that also can follow sucker rod is compensated voluntarily.Oil scraping plate and spring are installed in the rectangular opening on the core frame, and the core frame is contained in the inner chamber of adapter sleeve, adapter sleeve lower end and the screwed connection of oil well interface, upper end and upper press cover screwed connection.Place the sealing ring sealing between core frame and the upper press cover.
The beneficial effects of the utility model are: the one, and simple in structure, easy for installation, manufacture economy; The 2nd, the alignment error of sucker rod is had compensating action voluntarily, reduce the running resistance of eccentric wear and sucker rod; The 3rd, can improve application life greatly, save maintenance cost, reduce the economic loss that stops production and cause because of maintenance, and reduce leakage pollution.
Four, description of drawings:
Fig. 1 is the assembling stereogram that the utility model is cut open.
Fig. 2 is the stereogram that the utility model core frame part is cut open.

Fig. 4 is that the utility model is installed the stereogram that the fairlead part is cut open.
Fig. 5 is the stereogram that the utility model adapter sleeve part is cut open.
Five, the specific embodiment:
Below in conjunction with drawings and Examples the utility model is further specified.
1. install fairleads, 2. sealing ring, 3. upper press cover, 4. oil scraping plate, 5. spring, 6. adapter sleeve, 7. core frame among Fig. 1.Oil scraping plate 4 and spring 5 are installed in the rectangular opening on the core frame 7, and core frame 7 is installed in the inner chamber of adapter sleeve 6, adapter sleeve 6 lower ends and the screwed connection of oil well interface, upper end and upper press cover 3 screwed connections.Place sealing ring 2 sealings between core frame 7 and the upper press cover 3.
It is shaped as cylinder Fig. 2 SMIS frame 7, vertical on its face of cylinder, layering, has several rectangular openings alternately, is used to install oil scraping plate 4, rectangular opening central authorities have cylindrical hole, its slightly larger in diameter is in the minor face size of rectangular opening, and the degree of depth is not bored, and is used for mounting spring 5.
Among Fig. 3 oil scraping plate 4 its be shaped as cuboid, an end face has a semicircle breach, adopts organic friction material to manufacture, oil scraping plate is installed in the rectangular opening on the core frame 7, compresses with spring 5.
Special-purpose auxiliary when installation fairlead 1 is on-the-spot the installation among Fig. 4, it is shaped as elongated cylinder, and an end has tapering, and the other end has cylindrical hole, and using method is that it is enclosed within the sucker rod end, guiding sucker rod oil wiper can successfully be enclosed within on the sucker rod.
