Description
Technical field
The present invention relates to 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 is mainly applicable to 3m stroke.
Background technology
In oil exploitation, oil is extracted out by the main beam pumping unit that adopts from oil well.At present, conventional beam pumping unit is generally made up of polished rod eye, horse head, walking beam, frame, connecting rod, reducer, crank, bascule, base, frame and motor etc., but stroke is short, discharge capacity is little, volume is large, Heavy Weight, energy consumption are high shortcoming that the beam machine of this structure also exists, the main problem also existed because self power generation causes electrical network to distort.
In order to solve the problem, in prior art, propose following patented technology:
As China Patent No. " 201120146696.0 " discloses a kind of pulley stroke-lengthening beam pumping unit, its publication date is on November 16th, 2011, it comprises frame, walking beam, horse head, upper movable pulley, lower movable pulley, crossbeam connecting rod, load load-bearing band, sling device, motor, reducer and crank, between the power output shaft of motor and the power input shaft of reducer, transmission device is installed, the power output shaft of reducer is provided 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 thereof of crossbeam connecting rod is on the right part of walking beam, the lower end of crossbeam connecting rod is hinged on crank.
And for example China Patent No. " 02212499.3 " discloses a kind of wheel type oil pumping unit, its publication date 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 journey wheel, one end of walking beam is connected with support, the other end is taken turns by flexible piece be connected with increasing journey, and middle part is connected with connecting rod crossbeam.
But with the prior art that above-mentioned patent document is representative, in actual use, still also there is following defect:
One, because the friction between wellhead oil pumping device and pumping pipelines is very large, make to occur gap between wellhead oil pumping device and pipeline, Long-Time Service causes gap to increase gradually, and the speed of oil pumper in upwards oil pumping process is constant in prior art, this flows out between gap with regard to causing the oil extracted to have part at every turn, along with the increase gradually in gap, the oil mass that oil pumper is not only each extracted is few, from grease hole to mid-term or oil well in late period time, even can not extract oil out to come in oil well, the oil pumping rate of oil well is low; Two, because counterweight when beam machine starts all is in the bottom of its movement locus at every turn, and the weight of counterweight is very heavy, counterweight to be moved to peak from the minimum point of its movement locus, powerful motor is needed 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 maintain oil pumping running, cause the power consumption of oil pumper high; Three, when counterweight moves from the peak of its track to minimum point, because the weight of counterweight is very heavy, its undershoot speed can be quickly, when the undershoot speed of counterweight is greater than the rotating speed of motor, the potential energy in its down stroke process will convert electric energy to, thus produces larger pulse current, electrical network is made to produce serious distortion, cause the large area of motor device shut down and crash, namely produce so-called " shaking electric " phenomenon, thus cause device damage and oil pumping to stop; Four, current, beam pumping unit must refuel to main box to increase lubricity in the running, but after refueling, the phenomenon of leakage of oil easily appears in gearbox, there is larger potential safety hazard in oil pumping process; Five, the entirety deadweight 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 lifting rope down stroke is run, now on lifting rope without oil load, crank is only subject to the deadweight impact force of walking beam and horse head, when lifting rope upstroke is run, crank be subject to walking beam and horse head deadweight impact force and take out the gravity of oil, therefore, in oil pumping process, the impact force that crank is subject to uneven and at any time change, easily cause 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.
