Description
Technical field
The utility model relates to oil exploration equipment technical field, particularly a kind of balance sysmte without beam type hydraulic pumping unit.
Background technology
Oil pumper is the requisite a kind of oil production equipment of oil exploitation industry.At present, oil pumper traditional both at home and abroad is all furnished with the balancing weight of several tons and even tens tons, to solve the equilibrium problem of machine, this balance mode can increase the weight of complete machine, be unfavorable for transport and the installation of oil pumper, and often because of the so-called negative power of the not good appearance of balance, cause extremely bad impact to system effectiveness and performance.For solving these equilibrium problems, its balance mode must be changed.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of balance sysmte without beam type hydraulic pumping unit, utilizes the balancing technique of accumulator and composite cylinder to solve equilibrium problem and improves balance quality, substantially reduce the weight of complete machine.Its technical scheme is:
A kind of balance sysmte without beam type hydraulic pumping unit, comprise fuel tank, hydraulic pump, first one way valve, first overflow valve, second one way valve, second overflow valve, composite hydraulic cylinder, accumulator and two four-way electromagnetic reversing valves, composite hydraulic cylinder comprises cylinder rod, oil pocket is driven on first, lower driving oil pocket and second drives oil pocket, first one way valve is arranged on the pipeline of hydraulic pressure delivery side of pump, first overflow valve one end communicates with the first one way valve, the first overflow valve other end communicates with fuel tank, the oil-in (F) of two four-way electromagnetic reversing valves is connected with oil return opening with one way valve respectively with (H), two four-way electromagnetic reversing valve oil-outs (D) are connected with lower driving oil pocket with driving oil pocket on first of composite hydraulic cylinder respectively with (E), 3rd one way valve drives oil pocket to be connected with on accumulator and second of composite hydraulic cylinder, second one way valve is connected with oil-in with the 3rd one way valve, second overflow valve is arranged on pressure meter on the 3rd pipeline between one way valve and accumulator and is contained on the pipeline between overflow valve and accumulator.
The utility model patent by electric liquid coordinated signals, utilizes accumulator and composite hydraulic cylinder to solve balance of well pumping unit problem, and with pressure during pressure meter monitoring accumulator charge and discharge hydraulic oil.Zero-pressure and negative pressure will be formed when sucker rod moves downward driving oil pocket at present with the weight of self several tons of weight, hydraulic oil now in accumulator by act on composite hydraulic cylinder second on drive oil pocket to piston rod by generation one hydraulic action upwards to balance the gravity of sucker rod, thus reach dynamic equilibrium.When sucker rod moves upward, the hydraulic oil in accumulator act on composite hydraulic cylinder second on drive oil pocket to overcome the self gravitation of sucker rod and the active force of downhole pump, to reach balance.By accumulator in the utility model, drive oil pocket and connecting line to solve on second balance precision that equilibrium problem can improve oil pumper, to reach dynamic equilibrium.
