Abstract
The utility model relates to an oil production system for an oil field, comprising a foundation, a guide track, a motor, a coupling, a speed reducer, a steel frame, a balance tank, a polished rod, a polished rod eye, an elevating belt and a driven wheel and a drive belt which passes through the polished rod eye at one end and is connected with the balance tank and with two ends of the elevating belt which bypasses the driven wheel through the drive wheel at the other end, forming a closed drive ring. The utility model has the advantages of good balance result, low power consumption, high efficiency, convenient adjusting for punching number of stroke, short drive chain, less drive parts, low manufacturing price, easy maintenance, low running cost, convenient adjusting work parameter and suiting for oil production in a plurality of oil fields.
Description
Technical field
The utility model relates to a kind of extracting device of oil in oil field.
Background technology
At present extensively adopt in the oil field two big class oil pumpers, beam pumping unit and no beam pumping unit.Beam pumping unit is sturdy and durable, but efficient is low, energy consumption big, the stroke jig frequency is regulated difficulty.No beam pumping unit good balance effect, energy consumption is low, efficient is high, and the stroke jig frequency is easy to adjust; But cost height, consumable accessory are many, difficult in maintenance.
Summary of the invention
The objective of the invention is to avoid weak point of the prior art, and provide a kind of cost the low and closed oil pumper of ring for ease of maintenaince.
Can take following technical scheme to realize purpose.
Encircle closed oil pumper, comprise basis, guide rail, motor, reducer, steelframe, tandem-driving bogie, polished rod, polished rod eye, rotating band, driving wheel, elevator belt, driven pulley; One end of rotating band connects polished rod eye, and the other end connects tandem-driving bogie by driving wheel, and walks around the elevator belt that driven pulley and two ends are connected polished rod eye, tandem-driving bogie respectively and forms closed transmission ring.
The relative prior art of present technique has following advantage and effect
Good balance effect, energy consumption is low, efficient is high, and the stroke jig frequency is easy to adjust; Driving-chain is short, drive disk assembly is few, cost is low, be easy to safeguard that running cost is low that running parameter is easy to adjust, is applicable to that the exploitation of most of oil wells is used.
Description of drawings
The closed oil pumper structure chart of Fig. 1 ring.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
In conjunction with embodiment technical scheme is described in detail.
Embodiment 1, encircle closed oil pumper, comprise basis 19, guide rail 14, motor 18, shaft coupling 17, reducer 16, steelframe 8, tandem-driving bogie 9, polished rod 6, polished rod eye 3, elevator belt 2, driven pulley 1, rotating band 4.One end of rotating band 4 connects polished rod eye, and the other end connects tandem-driving bogie by driving wheel, and walks around the elevator belt that driven pulley and two ends are connected polished rod eye, tandem-driving bogie respectively and forms closed transmission ring.Motor is a reversing motor, can realize commutation by electrical control.Reducer is a pinwheel reducer, is connected with motor by shaft coupling.The output shaft of reducer links to each other with the axle of driving wheel 5 with chain 13 by sprocket wheel 15,20.Another spindle nose of driving wheel 5 has a gear and sprocket wheel and axle to rotate synchronously, and it can drive stroke and regulate tooth bar 11 motions, and the position of top dead centre travel switch 10 and following indication travel switch 12 can be regulated, in order to the commutation of control motor.Driving wheel 5 and axle are installed in the bottom of steelframe, driven pulley 1 is one or one group of pulley, elevator belt is one group of wire rope, belt or chain, one end of rotating band 4 connects polished rod eye, the other end connects tandem-driving bogie by driving wheel, and walks around the elevator belt that driven pulley and two ends are connected polished rod eye, tandem-driving bogie respectively and forms closed transmission ring.
During oil pumper work, just anti-phase the rotatablely moving of reversing motor drives the just anti-phase rotation of driving wheel, moves up and down by wire rope drive polished rod eye by reducer and sprocket wheel, chain, because of polished rod is fixedlyed connected with polished rod eye, the realization polished rod moves up and down and drives the oil extraction pump oil recovery.Drive stroke adjusting tooth bar 11 when the pinion of driving wheel axle head and driving wheel rotate synchronously and move up and down, regulate the position of top dead centre travel switch and lower dead center travel switch and can regulate stroke easily.The rotating time and the frequency by the control reversing motor can be regulated the oil pumper running parameter easily.During workover treatment, can oil pumper be removed from well head, reset again after having repaiied with the telephone-moving mechanism of motor by the steelframe bottom.
Embodiment 2, encircle closed oil pumper, on the basis of embodiment 1, driving wheel is the steel cable wheel, rotating band is that an end is fixed in two groups of wire rope on the driving wheel, wherein one group of wire rope twines the other end connection polished rod eye of overdriving after taking turns, and another group wire rope was connected the tandem-driving bogie bottom after twining the steel cable wheel by opposite rotation direction.
Embodiment 3, encircle closed oil pumper, on the basis of embodiment 1, driving wheel is a belt pulley, rotating band is that an end is fixed in two groups of belts on the driving wheel, wherein one group of belt twines the other end connection polished rod eye of overdriving after taking turns, and another group belt was connected the tandem-driving bogie bottom after twining belt pulley by opposite rotation direction.
Embodiment 4, encircle closed oil pumper, on the basis of embodiment 1, driving wheel is a sprocket wheel, and rotating band is a chain, and an end is connected on the polished rod eye, and the other end is walked around driving wheel and is connected the tandem-driving bogie bottom.
Embodiment 5, encircle closed oil pumper, on the basis of embodiment 1, motor, reducer are directly installed on the basis.
Embodiment 6, encircle closed oil pumper, on the basis of embodiment 1, the stroke governor motion is installed in an end of driving wheel.
