Abstract
The utility model relates to a hydraulic pressure energy saving oil pump to drill the petroleum. The utility model comprises a machine frame, a strap and a roller; one end of the strap is fixed on the machine frame and the other end is connected with the smooth pole of the oil pump; the roller which is positioned on the strap and can move up and down is connected on the piston pole of the dydraulic pressure power device through the gravity balancing block. The utility model has the advantages of the beam oil pump and the chain oil pump, has a simple structure and a strong environment applying capability; the utility model adopts the hydraulic power transmission, the whole machine can be operated steadily, has a good operating capability, has a low energy consumption, a low cost, is safe and reliable, has a low failure ratio and a small repairing volume, takes little space and is beneficial to be popularized.
Description
Technical field
The utility model relates to a kind of fluid pressure type energy-saving pumping unit, is oil drilling and extracting equipment.
Background technology
Oil field oil pumper commonly used generally is divided into two big classes: beam type and chain type (vertical), beam type major defect are that counterbalance effect is poor, the energy consumption height, and floor space is big; Chain type (vertical) has certain counterbalance effect, and floor space is little, but its maximum shortcoming is environment (field) bad adaptability, and consumable accessory is many, and running cost height, and load (polished rod) end is in case lose to carry then burns motor or complete machine is scrapped.In addition because the both adopts motor to slow down through reducer, to rotatablely move by mechanical mechanisms such as sprocket wheel, chain or crank connecting links becomes straight reciprocating motion again, realize oil pumping, thereby transmission efficiency is low, and sucker rod motor in upper and lower motion is all wanted work done, and energy consumption is big.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of simple in structure, environmental suitability is strong, and complete machine operates steadily, and running cost is low, and is safe and reliable, and fault rate is low, and maintenance capacity is little, the fluid pressure type energy-saving pumping unit that occupation of land face is little.
Fluid pressure type energy-saving pumping unit described in the utility model, comprise frame, belt, cylinder, one end of belt is fixed on the frame, and the other end of belt connects oil pumping polish rod, and it places the cylinder that pumps on the belt to be connected on the piston rod of hydraulic power unit by the gravitational equilibrium piece.
In the utility model:
The gravitational equilibrium piece for the gravitational equilibrium dolly for well, further strengthen operation stability, reduce the operation energy consumption.
Hydraulic piston cylinder power in the hydraulic power unit is provided by motor and hydraulic pump, wherein is connected to hydraulicdirectional control valve, realizes energy-conservation automatic control.
The weight of the balance weight by changing the gravitational equilibrium dolly, the balance well head promotes load effectively; When sucker rod descended, because the effect of reversal valve, motor needn't be made reverse merit and be in the idling running.And the one-level hydraulicefficiency is greatly improved than multi-stage mechanical transmission, thereby realizes truly energy-conservation.
Change the direction of motion by reversal valve, more steady and do not have an impact than mechanical mechanism; The hydraulically powered centre of effort is in load center, and without any the deflection moment of torsion, this is that other type is not available at present.So the complete machine consumable accessory is few, reduce the maintenance frequency and expense, prolong machine life.
Carry when well head loses suddenly, during as disconnected bar or disconnected rope, fluid pressure drive device is effectively controlled the balanced body decrease speed, to the bottom dead centre autostop, thereby avoids because of the infringement of weightlessness to machine, and is safe and reliable.
When the well head load increases suddenly, can not cause damage, and machine can run well to machine and hydraulic system.
By the control device of hydraulic system, can easily adjust stroke, jig frequency, fast on slowly down or the oil production technology requirement under going up soon slowly, conformability is good.
The utility model collection beam pumping unit and chain type oil pump advantage, simple in structure, environmental suitability is strong, the hydraulic power transmission, complete machine operates steadily, runnability is good, and energy consumption is low, and running cost is low, and is safe and reliable, fault rate is low, and maintenance capacity is little, and occupation of land face is little, is beneficial to and applies.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
Fig. 1, the utility model one example structure schematic diagram.
Among the figure: the moving cylinder, 7 that 1 hydraulic pump, 2 motors, 3 hydraulic control valves, 4 piston rods, 5 gravitational equilibrium dollies, 6 move up and down is decided cylinder, 8 belts, 9 polished rods, 10 hydraulic piston cylinders.
The specific embodiment
As shown in the figure, fluid pressure type energy-saving pumping unit described in the utility model, comprise frame, belt 8, cylinder 6,7, one end of belt 8 is fixed on the frame, the other end of belt 8 connects oil pumping polish rod 9, place the cylinder that pumps 6 on the belt 8 to be connected in by gravitational equilibrium dolly 5 on the piston rod 4 in the hydraulic piston cylinder 10 of hydraulic power unit, the power of hydraulic piston cylinder 10 is provided by motor 2 and hydraulic pump 1, wherein is connected to hydraulicdirectional control valve 3.
Three phase alternating current motor 2 drives hydraulic pump 1, produces hydraulic oil, through hydraulicdirectional control valve 3, for fluid pressure drive device provides power, pumps thereby make piston rod 4 drive 5 generations of gravitational equilibrium dolly.Belt 8 is through cylinder 6,7, and drive polished rod 9 is done and pumped, and realizes oil pumping.
Claims (3)
1, a kind of fluid pressure type energy-saving pumping unit, comprise frame, belt, cylinder, one end of belt is fixed on the frame, and the other end of belt connects oil pumping polish rod, it is characterized in that placing the cylinder that pumps on the belt to be connected on the piston rod of hydraulic power unit by the gravitational equilibrium piece.
2, oil pumper according to claim 1 is characterized in that the gravitational equilibrium piece is the gravitational equilibrium dolly.
