Description
Technical field
The utility model relates to a kind of oil pumper, particularly a kind of hydraulic power beam pumping unit.
Background technology
Oil pumper is widely used in the exploitation of crude oil.Tradition beam pumping unit exists that energy consumption is large, structure bulky, bascule are difficult to the drawbacks such as adjustment.The utility model devises a kind of hydraulic power beam pumping unit, utilizes hydraulic cylinder to provide power, and the mode of counterweigh load, realizes crude oil production, has the advantages that structure is simple, counterweight is adjustable, save energy consumption, has higher promotional value.
Summary of the invention
The purpose of this utility model is exactly the deficiency existed for prior art, provide a kind of hydraulic power beam pumping unit, hydraulic cylinder is utilized to provide power, the mode of counterweigh load, realize crude oil production, have the advantages that structure is simple, counterweight is adjustable, save energy consumption, there is higher promotional value.
A kind of hydraulic power beam pumping unit, its technical scheme is: primarily of PLC, driver, motor, oil pump, overflow valve, fuel tank, hydraulic cylinder, piston rod, counterweight, walking beam, frame, horse head, sucker rod and production tree composition; The electric machine rotation that described PLC is connected with oil pump by driver control, the entrance of described oil pump connects fuel tank, and oily delivery side of pump is connected with the overflow valve for the protection of fluid pressure line; Described hydraulic cylinder is on the ground hinged, hydraulic cylinder top is respectively equipped with the pouring orifice be connected with overflow valve, the draining armatine be connected with fuel tank, hydraulic cylinder inwall coordinates with the piston coaxial be arranged on bottom piston rod, is provided with the drain tap second be connected with fuel tank bottom hydraulic cylinder; Piston rod in described walking beam one end and hydraulic cylinder is hinged, and the other end is provided with the horse head relying on steel wire hang sucker rod, and be arranged in the middle part of walking beam and be fixed in the frame on ground, walking beam is provided with the counterweight for balancing the sucker rod load coaxial with production tree.
During sucker rod upstroke, the pouring orifice of hydraulic cylinder is opened, draining armatine is closed, drain tap second is opened, PLC is by driver control electric machine rotation, hydraulic oil sucks from fuel tank by driven by motor oil pump, oil pump is by the upper cavity of hydraulic oil by the pouring orifice injection liquid cylinder pressure of hydraulic cylinder, hydraulic oil is moved downward by piston driving piston rod, the hydraulic oil of cylinder lower cavity is back to fuel tank through drain tap second, piston rod drives walking beam end to move down, and the horse head of the walking beam other end drives sucker rod to move upward by wire rope, completes upstroke oil recovery action.During sucker rod down stroke, oil pump quits work, pouring orifice is closed, draining armatine is opened, drain tap second is opened, and because sucker rod deadweight drives the horse head of walking beam to move down, the walking beam other end drives piston rod upwards lifting, hydraulic cylinder upper cavity hydraulic oil is back to fuel tank through draining armatine, and cylinder lower cavity hydraulic oil passes through drain tap second from fuel tank inhalant liquid force feed.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
