Abstract
The utility model relates to a hydraulic driver for a hydraulic rocker oil pumping unit for oil exploitation in the oilfield. One motor drives one oil pump, the oil pump is communicated with an oil inlet on a valve body, one oil outlet on the valve body is communicated through the oil pump and the C-end of one oil cylinder with the E-end of the other oil cylinder, and the other oil outlet of the valve body is communicated through an oil pipe and the D-end of one oil cylinder with the F-end of the other oil cylinder. The piston of one oil cylinder moves forward, and the piston of the other oil cylinder moves back, and vice versa; two pistons move to drive one rocker to swing, and one rocker simultaneously drives two oil pumping rods respectively to pump oil from the well. The utility model has the advantages of simple structure, energy saving, high work efficiency and low cost.
Description
The utility model is the fluid drive that uses on the hydraulic pressure fork pumping unit of oil field oil recovery usefulness.
The sleepy hair style pumping unit that the pumping unit that present oil field is used generally uses, it is to slow down by belt transmission, slows down by retarder again, to rotatablely move with eccentric wheel, connecting rod becomes linear reciprocating motion again, adds heavy counterweight again, mechanism's bulky complex, big energy-consuming, efficient is low.Neoteric hydraulic type fork pumping unit, particularly hydraulic type fork twin-well oil-pumping machine are provided with supporting with it fluid drive, and can not be applied to very soon recovers the oil produces.
The purpose of this utility model will design a kind of can being applied on the hydraulic type fork twin-well oil-pumping machine, can guarantee the Hydraulic Power Transmission System of oil extraction operation performance requirement.
The purpose of this utility model is realized by following structure.
Motor (3) links to each other with oil pump (5) by Coupling Shaft, and oil pump (5) communicates with oilhole (7) on the valve body (9) by oil pipe.Oilhole (11) on the valve body (9) communicates with the C end of oil cylinder (14) and the E end on the oil cylinder (22) respectively through oil pipe, oilhole (12) communicates with the D end of oil cylinder (14) and the F end of oil cylinder (22) respectively through oil pipe, and oilhole (24) communicates with oil pump (5) through oil pipe.Oilhole (13), (24) communicate with oilhole (10), (1) on the valve body (9) respectively through oil pipe, and AB block (18) is connected as a single entity with commutation piece (21).The cavity oil return of commutation piece (21) communicates with fuel tank (4) through oil pipe, and the oilhole (8) on the valve body (9), (25) communicate with fuel tank (4) through oil pipe.
Owing to adopt two pistons, piston rod in two oil cylinders of an oil pump driving, two piston rods drive a fork motion simultaneously, can pump from two oil wells simultaneously, and are simple in structure, save the energy, and cost is low, high working efficiency.
Fig. 1 is the fluid drive systematic schematic diagram.
Concrete structure accompanying drawings of the present utility model and embodiment provide.
Select suitable motor (3), oil pump (5) on demand.Require design valve body (9), spool (2), oil cylinder (14), (22), piston (15), (20), piston rod (16), (19), commutation piece (21) and block whole Hydraulic Power Transmission Systems such as (18), assembly and adjustment then according to the sucker rod service behaviour.Fork (17) is flapped toward oil cylinder (14), depresses B block (18), and commutation piece (21) moves oilhole (24) is communicated with oilhole (23), and former hyperbaric chamber oil flows back to fuel tank (4) from oilhole (13) through oil pipe.The part high pressure oil that comes out from oil pump (5) enters cavity through oil pipe from oilhole (24) and enters valve body (9) through oil pipe and oilhole (1) again by oilhole (23), promotes spool (2) motion, and spool (2) blocks oilhole (8).Another part high pressure oil that oil pump (5) is got enters valve body (9) from oil inlet hole (7) inner chamber is moved to D from C through the C end promotion piston (15) that oil pipe enters oil cylinder (14) respectively by oilhole (11), the oil that comes out from oilhole (11) enters from the E end of oil cylinder (22) through oil pipe simultaneously and promotes piston and move to F from E, make fork (17) be flapped toward oil cylinder (22) and press to A block (18), the oil of the oil of oil cylinder (14) D end and oil cylinder (22) F end is through oil pipe and oilhole (12), (25) flow back to fuel tank (4), A block (18) rotation, oilhole (13) is communicated with oilhole (24), spool (2) is moved round about.Spool (2) blocks oilhole (25), and high pressure oil enters valve body from oilhole (7) and comes out to flow into oil cylinder (14) D end from oilhole (12), and oil cylinder (22) F end promotes piston motion, makes fork (17) be flapped toward oil cylinder (14).
Claims (1)
1, a kind of fluid drive, mainly comprise spool (2), motor (3), fuel tank (4), oil pump (5), valve body (9), oil cylinder (14), (22), piston (15), (20), fork (17), AB block (18), it is characterized in that: the oilhole (17) on the valve body (9) communicates with oil pump (5) through oil pipe, oilhole (11) on the valve body (9) communicates with the C end of oil cylinder (14) and the E end of oil cylinder (22) respectively through oil pipe, oilhole (12) divides through oil pipe to be held identical with the D end of oil cylinder (14) and the F of oil cylinder (22), oilhole (24) communicates with oil pump (5) through oil pipe, oilhole (13), (24) through oil pipe respectively with valve body (9) on oilhole (10), (1) communicate, AB block (18) is connected as a single entity with commutation piece (21).
