Moreover, balance force is more convenient to adjust.

Description

A kind of gas balance type hydraulic pumping unit
Technical field
The utility model relates to oil pumper technical field, and especially a kind of gas balance type hydraulic pumping unit is mainly used in oil field sucker rod pumping technical field.
Background technology
Common beam pumping unit is generally to be converted electrical energy into and rotatablely moved by motor, recycles mechanical method and changes straight reciprocating motion by rotatablely moving into and realize oil recovery.This type of drive not only efficiency is not high, and has caused the volume of oil pumper large, and this class oil pumper is also difficult to realize automatic control and remote control in addition.This class oil pumper generally carries out the balance of oil pumper by add balance weight iron on walking beam or crank simultaneously, and this balance mode counterbalance effect is bad, very power consumption.And adjust when equilibrant force and need mobile counterweight iron, the difficulty operating very.
Utility model content
The utility model is intended to address the above problem, a kind of gas balance type hydraulic pumping unit is provided, its volume is little, lightweight, cost of production is little, simple in structure, easy for installation, good balance effect and balance adjustment convenient, can realize centralized control and management, its technical scheme adopting is as follows simultaneously:
A kind of gas balance type hydraulic pumping unit, it is characterized in that: comprise base, hydraulic control circuit, driving hydraulic cylinder, walking beam, support, balancing cylinder, accumulator, horse head and sucker rod, described walking beam and support are rotationally connected, the cylinder barrel bottom of described driving hydraulic cylinder is hinged with base, drives the piston rod of hydraulic cylinder and the postbrachium of walking beam hinged; Cylinder barrel and the base of described balancing cylinder are hinged, and the piston rod of balancing cylinder and the forearm of walking beam are hinged; Described hydraulic control circuit is connected with the upper and lower chamber of piston that drives hydraulic cylinder by electromagnetic valve, the forearm of described horse head and walking beam is affixed, described sucker rod is connected with horse head, described accumulator has upper and lower chamber, the piston cavity of resorption of described balancing cylinder is connected by oil pipe with the cavity of resorption of accumulator, in the epicoele of described accumulator, is filled with non-combustible gas.
On technique scheme basis, the non-combustible gas of filling in the epicoele of described accumulator is nitrogen.
On technique scheme basis, in described hydraulic control circuit, be provided with overflow valve.
The utlity model has following advantage: replace traditional type of drive not only to improve efficiency by hydraulic-driven on the one hand, and greatly reduce the volume of oil pumper, and make the designs simplification of oil pumper, adopt hydraulically powered mode to be easy to the enforcement of the technology such as mechanical-electrical-hydraulic integration simultaneously, thereby can realize automatic control and remote control.Replace traditional counterweigh not only to improve counterbalance effect by gas balance on the other hand, also make the adjusting of equilibrant force become more convenient simultaneously.
Brief description of the drawings
Fig. 1: structural representation of the present utility model;
In figure: 1, base, 2, hydraulic control circuit, 3, drive hydraulic cylinder, 4, walking beam, 5, support, 6, balancing cylinder, 7, accumulator, 8, horse head, 9, sucker rod.
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1, a kind of gas balance type hydraulic pumping unit of the present embodiment, it is characterized in that: comprise base 1, hydraulic control circuit 2, drive hydraulic cylinder 3, walking beam 4, support 5, balancing cylinder 6, accumulator 7, horse head 8 and sucker rod 9, described walking beam 4 is rotationally connected with support 5, the cylinder barrel bottom of described driving hydraulic cylinder 3 is hinged with base 1, drives the piston rod of hydraulic cylinder 3 and the postbrachium of walking beam 4 hinged; The cylinder barrel of described balancing cylinder 6 and base 1 are hinged, and the forearm of the piston rod of balancing cylinder 6 and walking beam 4 is hinged; Described hydraulic control circuit 2 is connected with the upper and lower chamber of piston that drives hydraulic cylinder 3 by electromagnetic valve, described horse head 8 is affixed with the forearm of walking beam 4, described sucker rod 9 is connected with horse head 8, described accumulator 7 has upper and lower chamber, the piston cavity of resorption of described balancing cylinder 6 is connected by oil pipe with the cavity of resorption of accumulator 7, in the epicoele of described accumulator 7, is filled with non-combustible gas.
The non-combustible gas of preferably, filling in the epicoele of described accumulator 7 is nitrogen.
Preferably, in described hydraulic control circuit 2, be provided with overflow valve, thereby prevent the hypertonia destruction hydraulic control circuit in hydraulic control circuit 2.
In the course of work, when in upstroke: by the adjusting of hydraulic control circuit 2, make to drive the epicoele oil-feed cavity of resorption oil return of hydraulic cylinder 3, thereby make to drive the descent of piston of hydraulic cylinder 3, and then drive horse head 8 to drive sucker rod 9 to do upstroke by walking beam 4.The piston that meanwhile Compressed Gas in accumulator 7 promotes balancing cylinder 6 by the hydraulic oil of promotion balancing cylinder 6 cavity of resorptions does upstroke, thereby stroke is helped out, and the energy that accumulator 7 is stored in down stroke so is just released for auxiliary pumping unit and promotes sucker rod 9 in upstroke.When in down stroke: by the adjusting of hydraulic control circuit 2, make to drive the cavity of resorption oil-feed epicoele oil return of hydraulic cylinder 3, thereby make to drive the piston stroking upward of hydraulic cylinder 3, do downward movement at the Action of Gravity Field of sucker rod 9 and the driving effect lower sucker rod of driving hydraulic cylinder 3 like this.Meanwhile under the forearm of walking beam 4 drives, the piston of balancing cylinder 6 does downward movement, and hydraulic oil by balancing cylinder 6 cavity of resorptions promotes the piston stroking upward of accumulator 7, thereby a part for the high pressure nitrogen of compress energy storage device 7 epicoeles gravitional force of release when descending to the energy that drives hydraulic cylinder 3 to export and sucker rod 9 stores.
With way of example, the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
