Description
Affiliated technical field
The utility model relates to oil pumper, especially the accumulation of energy balanced hydraulic oil extractor that recovers the oil and use in a kind of oil field.
Background technology
At present, each employed oil pumper in oil recovery factory, oil field, mostly be quadric chain or single oil cylinder mechanism greatly, the balance of underground equipment and load is many to be realized with balance, promptly add first-class heavy balance weight, will strengthen weight of equipment and cost like this, also give to install to adjust and bring difficulty in the load corresponding end, in addition because the influence of counterweight and the restriction of mechanism, (travel limits of quadric chain and hydraulic jack) makes the increase finiteness of oil pumper stroke.In addition because downhole load is a variable, and counterweight is in case after adjusting, be exactly one quantitatively, so its dynamic loading is bigger, counterbalance effect is poor.
Summary of the invention
In order to overcome the in-problem deficiency of existing oil pumper, the utility model adopts the accumulator balance, and serial oil cylinders drives synchronously, and hinge stroke enlarger quickens to amplify stroke and realizes big stroke, low energy consumption, oil pumping fast.
The technical scheme that its technical problem that solves the utility model adopts is: the accumulation of energy balanced hydraulic oil extractor is by frame, head sheave, the hinge stroke amplifies acceleration mechanism, synchronous serial oil cylinders, accumulator, several parts such as hydraulic control system are formed, on the base of its bottom slide rail is arranged, the tower rack on top is connected on the base by slide rail and bolt, a day wheel support is arranged at the top of frame, bearing support and day wheel shaft and head sheave are arranged on it wheel support, a bracing frame is welded on the right of frame, there is one group of hinge stroke enlarger the inside, wherein below penult joint pin is fixed on fixed cover and the bracing frame, hinge stroke enlarger is by in succession outstanding rope and hanging on the head sheave of connecting rod, the opposite side of head sheave is by outstanding rope, the polished rod eye polished rod of ining succession, synchronous serial oil cylinders is arranged on base, piston rod links to each other with connecting rod, in the serial oil cylinders upper piston and lower piston are arranged synchronously, there is the oil cylinder connecting flange its centre, three oil pipes link to each other with hydraulic controller above the serial oil cylinders right side synchronously, bottom oil pipe links to each other with accumulator, be fixed with hydraulic controller on the base of bracing frame the right, accumulator is arranged above the hydraulic controller, and having oil pipe to link to each other, there is suspension cable on the frame right side.
Serial oil cylinders has two single piston oil-cylinders to be linked together by connecting flange synchronously.Piston rod and upper piston and lower piston are fixedly connected, have oilhole on two oil cylinders, oilhole is connected with hydraulic controller and accumulator by oil pipe, upper piston, lower piston and the connecting flange of serial oil cylinders are divided into four oil pockets with oil cylinder synchronously, wherein the epicoele of the epicoele of upper piston, cavity of resorption and lower piston communicates with hydraulic pressure oil inlet and oil return pipe, and the cavity of resorption of lower piston communicates with accumulator.
The hinge stroke amplifies, acceleration mechanism is made up of hinge, joint pin, guide rod fixed cover, guide rod fixed mount, movable guide pin bushing, guide rod and bracing frame.Connecting rod, hinge link with joint pin, and the following penult joint pin of hinge stroke enlarger is fixed on fixed cover and the bracing frame, and this joint pin and bracing frame can not relative motions, and fixed cover is fixed on the bracing frame, is used for fixing guide rod.Other joint pin does not connect with fixed cover, relative motion.Movable guide pin bushing and joint pin are fixedly connected, and they can slide up and down on guide rod by guide pin bushing.
During work, hydraulic controller is to synchronous serial oil cylinders upper piston epicoele fuel feeding, upper piston and lower piston are moved downward, with the hydraulic oil pressure of lower piston cavity of resorption to the accumulator accumulation of energy, on, lower piston drives piston rod and moves downward, piston rod is downward by connecting rod drivening rod pin, because following penult hinge pin is fixed, link pin drives hinge through, and the subtended angle between the hinge is increased, the joint pin of lifting above it, and be delivered to successively on the top connecting rod, top connecting rod is moved up, the outstanding rope on head sheave the right is made progress, underground equipment and polished rod move downward under the deadweight effect, and oil pumper is finished down stroke; Then, hydraulic controller is to the cavity of resorption fuel feeding of upper piston, and piston drives piston rod and moves upward, the subtended angle of hinge set is dwindled, connecting rod drives outstanding rope and moves downward, and head sheave is rotated, and the pressure in the lower piston cavity of resorption descends, accumulator is released can, to lower piston cavity of resorption fuel feeding, help to drive head sheave and turn clockwise, drive polished rod and underground equipment and move upward, oil pumper is finished upstroke, so goes round and begins again and realizes oil pumping.
The beneficial effects of the utility model are, the accumulation of energy balance, serial oil cylinders drives commutation synchronously, and hinge stroke enlarger quickens to amplify stroke and realizes big stroke, low energy consumption, oil pumping fast.
