Two, background technology
At present, for oil well that can not blowing, generally adopt the mechanical type oil pumper to recover the oil, as most widely used conventional beam-pumping unit, its walking beam is hinged on support by the beam travelling supporting seat, horse head is installed in the walking beam front end and is connected with sucker rod by lifting rope, the walking beam rear end is hinged by crossbeam and crank-link mechanism, motor drives crank-link mechanism work through reducer, crank-link mechanism drives walking beam reciprocally swinging in vertical guide by crossbeam, drive the upper and lower reciprocating motion of sucker rod by horse head, polished rod eye, realize oil pumping.Conventional beam-pumping unit have reliable operation, sturdy and durable, easy to maintenance, can be operated in the field throughout the year and not need advantages such as the special messenger guards, therefore, for over 100 years more than a hundred years, it is the first that conventional beam-pumping unit consumption in mechanical oil recovery occupy always; But its weak point is: conventional beam-pumping unit is subjected to the influence of its " four bars " mechanism, the load-torque that causes oily machine polished rod load to affact on the crank changes not according to sinusoidal rule, add the influence of the additional loads such as suspension point inertial load in the work, make the load-torque curve distortion occur, make the upstroke torque peak bigger than normal, the absolute value of down stroke peak value is less than normal, the crank balance moment of torsion that changes by sinusoidal rule can not fine balance with it, bigger peak value and less (bearing) value appear in the clean moment of torsion that crank-motion was exported in one week, thereby it is higher to influence the application life and the energy consumption of oil pumper.
Along with Oilfield developing, oil well liquid level descends, and whale day by day reduces, and the input amount of oil pumper constantly increases, and cuts down the consumption of energy and improves the problem in oil pumper application life and more and more loom large.
Three, summary of the invention
The purpose of this utility model provides a kind of fork variable-pitch beam formula energy-saving pumping unit, this oil pumper both can overcome existing beam pumping unit above shortcomings, can cut down the consumption of energy effectively again, increased the application life of oil pumper, sturdy and durable, convenient for installation and maintenance.
The utility model adopts following technical scheme to realize: fork variable-pitch beam formula energy-saving pumping unit comprises the rear-mounted beam-pumping unit that support, electric machine, brake gear, reducer, crank-link mechanism, crossbeam assembly and the walking beam, horse head, the polished rod eye that are fixed on the base constitute.Be characterized in being provided with the fork balanced controls at the walking beam afterbody of rear-mounted beam-pumping unit.Described fork balanced controls are made of active fork, pull bar, passive fork and bascule, the active fork is fixed in crossbeam assembly place and is positioned at two sides of walking beam, passive fork is hinged on the passive fork bearing place that is positioned at the walking beam afterbody, initiatively fork is hinged by pull bar and passive fork, on the passive fork bascule is installed.
The utility model adopts technique scheme, because the effect of fork balanced controls, the fork swing, bascule produces the counter balance torque of a variation, make the net torque curve of reducer output milder, reduce the root-mean-square value of clean moment of torsion, improved the counterbalance effect of this oil pumper, reach the purpose that cuts down the consumption of energy, thereby improved oil recovery efficiency.The utility model is reasonable in design, reduced the stressed of its four mechanism of company, changed the counter balance torque of four connecting rods, because the fork balanced controls are that rigid structures has improved reliability of structure, conventional machine characteristics simple in structure, firm, sturdy and durable, easy to maintenance have been inherited, reduce the motor load coefficient, improved the overall efficiency of this machine, realized energy-saving and cost-reducing goal of the invention.
