Description
Technical field
The present invention relates to the oil recovery machiner technical field, relate in particular to the interactive single driven wheel of a kind of multifunctional dual-arm from variable-speed well pumping unit, this oil pumper mainly is applicable to the 3m stroke.
Background technology
In oil exploitation, mainly adopt beam pumping unit that oil is extracted out from oil well.At present, conventional beam pumping unit generally is comprised of polished rod eye, horse head, walking beam, frame, connecting rod, reducer, crank, bascule, base, frame and motor etc., but the beam machine of this structure exists, and stroke is short, discharge capacity is little, volume is large, Heavy Weight, shortcoming that energy consumption is high, the main problem that causes the electrical network distortion because of self power generation that also exists.
In order to address the above problem, following patented technology has been proposed in the prior art:
A kind of pulley stroke-lengthening beam pumping unit is disclosed such as China Patent No. " 201120146696.0 ", its open day is on November 16th, 2011, it comprises frame, walking beam, horse head, upper movable pulley, lower movable pulley, the crossbeam connecting rod, load load-bearing band, the sling device, motor, reducer and crank, between the power output shaft of motor and the power input shaft of reducer transmission device is installed, power output shaft at reducer is equipped with crank, the middle part of the walking beam that can swing up and down is hinged on the top of frame, the upper end of crossbeam connecting rod is hinged on the right part of walking beam, and the lower end of crossbeam connecting rod is hinged on the crank.
And for example China Patent No. " 02212499.3 " discloses a kind of wheel type oil pumping unit, its open day is on 04 02nd, 2003, comprise base, motor, reducer, crank, connecting rod crossbeam, balance arm, lifting rope, support, counterweight block, the top device of support increases the journey wheel, one end of walking beam links to each other with support, the other end by flexible piece with increase journey wheel and be connected, the middle part links to each other with the connecting rod crossbeam.
But in actual use, still also there is following defective in the prior art take above-mentioned patent document as representative:
One, because the friction between wellhead oil pumping device and pumping pipelines is very large, so that the slit occurs between wellhead oil pumping device and the pipeline, the long-term use causes the slit to increase gradually, and the speed of oil pumper in the oil pumping process that makes progress is constant in the prior art, this has part with regard to the oil that causes extracting at every turn and flows out between the slit, gradually increase along with the slit, oil pumper not only each oil mass that extracts is few, from the grease hole to the mid-term or late period during oil well, even can not come from extraction oil in the oil well, the oil pumping rate of oil well is low; Two, since beam machine when starting at every turn counterweight all be in the below of its movement locus, and the weight of counterweight is very heavy, counterweight to be moved to peak from the minimum point of its movement locus, need powerful motor to start, therefore the startup of beam pumping unit is difficult, but after beam pumping unit starts, only need again a half-power of heavy-duty motor can keep the oil pumping running, cause the power consumption of oil pumper high; Three, when counterweight moves to minimum point from the peak of its track, because the weight of counterweight is very heavy, its undershoot speed can be very fast, when the undershoot speed of counterweight during greater than the rotating speed of motor, the potential energy in its down stroke process will convert electric energy to, thereby produces larger pulse current, make electrical network produce serious distortion, the large tracts of land that causes motor device is shut down and deadlock, namely produces so-called " rolling electricity " phenomenon, thereby causes device damage and oil pumping to stop; Four, present, beam pumping unit must refuel to increase lubricity to main box in the running, but after refueling, the phenomenon of leakage of oil easily appears in gearbox, exists larger potential safety hazard in the oil pumping process; Five, the deadweight of the integral body of beam pumping unit is very heavy, and the steel material of consumption is large, and the cost of buying oil pumper is high; Six, when the lifting rope down stroke is moved, without oil load on the lifting rope this moment, crank only is subject to the deadweight impact force of walking beam and horse head, when the lifting rope upstroke is moved, crank is subject to the deadweight impact force of walking beam and horse head and the gravity of the oil of taking out, therefore, in oil pumping process, the impact force that crank is subject to is inhomogeneous and changing at any time, easily causes crank to damage, not only affect the application life of equipment, serious also can cause security incident, and crank damaged after, be difficult to repair, if and change accessory, then cost is higher.
