Abstract
Provided is a piston cylinder in an oil pumping device of an intelligent intermittent bailing type oil pumping unit. The piston cylinder is formed by a rubber barrel and metal frameworks; the rubber barrel is of a cylindrical shape and made by means of sulfuration of fluorine rubber added with graphite; a cylindrical surface at the upper end and the cylindrical surface at the lower end are provided with threads; the outer surface of an outer cylinder of the rubber barrel is provided with the metal framework made of 38 CrMoAl materials in an embedded mode; the metal framework is of a vertical strip shape; two sides of the metal frame are respectively provided with a vertical groove; the cross section of each vertical groove is of an H shape; small holes are arranged in each vertical groove of the metal framework; eighteen metal frameworks are evenly distributed on a cylindrical outer surface of the rubber barrel; the surfaces, exposed on the cylindrical outer surface of the rubber barrel, of the metal frameworks are located in the same cylindrical surface with the outer cylinder of the rubber cylinder; the surfaces, exposed on the cylindrical outer surface of the rubber barrel, of the metal frameworks are provided with surface grooves; and the upper ends and the lower ends of the metal frameworks are provided with threaded fabrication holes. According to the piston cylinder in the oil pumping device, on the condition that an oil pipe does not need replacing, service life of the piston cylinder is greatly prolonged, and normal production of oil pumping is ensured, and cost of the oil pumping is reduced.
Description
Technical field
The invention belongs to the parts of petroleum machinery pumping unit, particularly the piston cylinder in a kind of Intelligent intermittent bailing formula pumping unit apparatus.
Background technique
Intelligent intermittent bailing formula pumping unit is to utilize among the bailing sucker rod once is extracted into aboveground petroleum pipeline with oil from the shaft bottom, and sucker rod is provided with piston cylinder.When needs are up when carrying oil since the pressure in the oil so that the piston cylinder deformed dilation seals up tube inner wall, could realize oil is drawn up.The swabs cylinder of past Intelligent intermittent bailing formula pumping unit is that polyurethane material is made, although can dilatancy reach the purpose of oil pumping, but tube inner wall is subject to the erosion of oil, there is a lot of defectives in tube wall, in addition, the oil pipe endoporus exists oval, the coaxality of tube and tube has error, there is 14 ~ 30 millimeters slit between the tube and tube, all the service life of piston cylinder caused very large impact, the piston cylinder of polyurethane is quick-wearing very, causes pump efficiency very low, even take out not oil and, affect greatly the normal production in oil field.Usually need to change preferably oil pipe of quality.Virtually strengthened the cost that recovers the oil.
Summary of the invention
The purpose of this invention is to provide a kind of Intelligent intermittent bailing formula oil pumping machine oil pumping piston cylinder.Piston cylinder can rise under the pressure of oil and seals tube inner wall when both guaranteeing to pump, and can solve again not more in the situation of renew oil pipe, prolongs greatly the working life of piston cylinder, guarantees the normal production of recovering the oil to reduce cost for oil production.
Content of the present invention:
A kind of Intelligent intermittent bailing formula pumping unit piston cylinder, it is characterized in that: piston cylinder is comprised of rubber tube and metal frame, and it is columniform that the sulfuration of fluorine rubber adding graphite forms rubber tube, on two cylndrical surface of upper and lower end screw thread is arranged; Be inlaid with the metal frame of 38CrMoAl material on the rubber tube outer cylinder outer surface, metal frame vertical bar shape, open the metal frame bi-side respectively vertical slot one, section forms H shape, be arranged with aperture in the vertical slot of metal frame, at the uniform 18 strip metal skeletons that are inlaid with of rubber tube cylindrical outer surface, be exposed at the metal frame face of rubber tube cylindrical outer surface and rubber tube outer cylinder on same cylndrical surface, the metal frame face that is exposed at the rubber tube cylindrical outer surface is distributed with groove, the screw thread auxiliary hole is arranged two ends up and down at metal frame.
Metal frame face at the rubber tube cylindrical outer surface has the cemented carbide spray-welding coating.
Advantage of the present invention:
It is a kind of novel swabs cylinder, need not to change in the situation of oil pipe, prolongs greatly the working life of piston cylinder, guarantees the normal production of oil recovery, reduces cost for oil production.
Description of drawings
Fig. 1 is the sectional drawing of Intelligent intermittent bailing formula oil pumping machine oil pumping piston cylinder.
Fig. 2 is the distribution map of metal frame in the rubber tube transverse section.
The plan view of Fig. 3 .1 metal frame.
The side view of Fig. 3 .2 metal frame.
Fig. 4 is the sectional view of metal frame.
Among the figure: 1 rubber tube, 2 metal frames, 3 apertures, 4 technique screws, 5 grooves, 6 vertical slot A, 7, vertical slot B.
Embodiment
Take 3 cun piston cylinders as example: piston cylinder external diameter 75mm, cylinder two ends screw thread M60 * 3, tube length 140mm, embedded with metal skeleton partial-length 100mm.
The structure of Intelligent intermittent bailing formula oil pumping machine oil pumping piston cylinder as shown in Figure 1, piston cylinder is comprised of rubber tube 1 and metal frame 2, and metal frame 2 assigns to distribute with 18 grades on the piston cylinder circumference, and it is fixed in the rubber tube 1 after through the vulcanization of rubber.(seeing the distribution map of Fig. 2 metal frame in rubber tube)
Rubber tube 1 is columniform, and two cylinders of upper and lower end are screw threads, is used for connecting upper low sleeve on the sucker rod.
The material selection of rubber be fluorine rubber, the inside adds the graphite of proper proportion, in order to improve the andfrictional conditions of rubber tube and oil pipe.
The bi-side of metal frame 2 (seeing the structural drawing of Fig. 3 .1,3.2 metal frames 2) have vertical slot A and vertical slot B, and shape approximation is in the H type, and (shown in the sectional view of Fig. 4 metal frame 2) also has the aperture of 5 Φ 3.5mm in vertical slot.
The material selection of metal frame 2 be 38CrMoAl, through quenching with Subsequent tempering, prevent distortion, adopt gas nitriding, make its surface hardness reach HV850 ~ 1000, the nitrogenize degree of depth can reach 0.3 ~ 0.5mm.Greatly strengthen its wear-resistant endurance.
The R37.5 arc-shaped surface that also has 2 frictions of part metals skeleton has adopted the method for surfacing cemented carbide, more improves its working life.
Vertical slot A, vertical slot B and five apertures all are to be full of rubber when sulfuration, and purpose is to prevent that metal frame 2 from running out of from rubber tube 1.After guaranteeing the being tube inner wall wearing and tearing, its residual fraction can not deviate from from rubber tube yet.So just avoided fully causing sucker rod jammed situation in well to occur because metal frame 2 comes off.
Two M4 screws on the metal frame 2 are when the vulcanization of rubber, are located and are fixed on the vulcanization of rubber mould with screw.
