Abstract
The utility model relates to a beam gas exhauster for exhausting natural gas in casing tubes of an oil well, which uses a beam of an oil pumping unit as the dynamic force to drive a piston to move back and forth in straight line through a connecting rod to complete the processes of gas suction and exhaust, and the aim of gas exhaust is achieved. Both ends of the connecting rod are in centripetal joint bearing structure. Machine parts are made of wear resistant and anticorrosive material, and a friction pair uses a self-lubrication mode. Compared with other gas exhausters in the technical field, the utility model has the advantages of high durability, no increase of dynamic force, improvement on working condition of the beam-pumping unit, accident reduction and no need of periodical manual oil charge.
Description
The walking beam air exhauster is a kind of model utility special device that is used to extract out rock gas in the oil gas casing.
The prior art of this technical field, in U.S. WORLD OIL/JULY.1992.P71～76, SPE11573 and three pieces of papers of SOUTHWESTERN PETROLEUN SHORT COURSE.88, the structure and the mounting point schematic representation of this air exhauster disclosed.When the work of the different air exhauster of disclosed three kinds of structures, all be complete machine along with piston rod is swung, a part of body weight is pressed on the piston rod, piston produces an angle with body, the radial component of generation makes the two be easy to wear and tear; Piston rod is lubricated by artificial intermittent oiling; The mounting point all is located between pumping unit connecting rod and the beam travelling supporting, has increased motor load (except the 3rd piece of paper).In addition, swing during owing to complete machine work, the suction that is installed on it, outlet valve pipeline also are easy to generate fatigue fracture.
In view of the problem that above-mentioned prior art exists, the purpose of this utility model is, design a kind of not easy to wear and can be durable in use, not manually intermittent oiling, do not increase the walking beam air exhauster that motor load also can improve pumping unit working condition, minimizing accident.
The structure and the mounting point of the utility model walking beam air exhauster, as shown in drawings: (1) horse head; (2) walking beam; (3) connecting rod; (4) go up garden post raceway; (5) dust guard; (6) garden post raceway under; (7) plunger pump; (8) piston; (9) body; (10) Aspirating valves; (11) outlet valve; (12) beam travelling supporting.
Body (9) is fixed on the base, and Aspirating valves (10) and outlet valve (11) are housed on it.By two ends all is the connecting rod (3) that plain radial bearing is formed, and walking beam (2) and air exhauster are combined as a whole, and by it the power of walking beam is passed to piston (8).In the power transmission process, connecting rod (3) only bears axial force, and external diameter does not produce wearing and tearing, and piston can not produce the angle of inclination yet in body.
Piston (8) is made with polytetrafluoroethylmaterial material.The friction ractor of this material has only 1/3 of cast iron, has improved the durability of piston friction pair; Also solved the corrosion-resistant problem simultaneously.Piston blank can be shaped with molding sintering, good manufacturability, and overall cost is than coming cheaply with other metal manufacturing.
Plunger pump (7) is contained in piston (8) and goes up the plane, and the every stroke of piston once drives plunger pump and sprays a lubricant oil, in order to the dust lip of lubricated dust guard (5).This self lubricating system is artificial intermittent oiling not.
Dust guard (5) is used the polytetrafluoroethylmaterial material die forming.Along with the swing of connecting rod (3), drive dust guard (5) and doing the arc rolling on the garden post raceway (4,6) up and down.
Air exhauster is installed between the horse head (1) and beam travelling supporting (12) on the walking beam (2).The work done of piston (8) down stroke pressurized gas, the rate of descent of horse head (1) in the reaction thrust damping of generation, makes it synchronous with the rate of descent of sucker rod gravity system.Air exhauster is installed on this position, not only can not increase motor load, but also has improved the working condition of pumping unit, has reduced the well head accident.
The technical characteristics of the utility model walking beam air exhauster, in having overcome above-mentioned prior art, existed easy to wear, increase the shortcoming of motor load, the artificial intermittent oiling of needs, the more important thing is to have solved the horse head rate of descent technical barrier out of control that home and abroad common beam pumping unit exists always.A new way that designs novel gas beam-balanced pumping unit has been opened up in the enforcement of the utility model walking beam air exhauster.
