Fig. 3 is the structural representation of the third embodiment of the present invention.
In figure, 1 horse head, 2 lifting ropes, 3 levers, 4 supports, 5 bases, 6 axis of centres bearings, 7 pressure sensors, 8 liquor pumps, 9 electric change valves, 10 front fluid boxes, 11 rear fluid boxes, 12 encoders, 13 intelligent controllers, 14 safety plugs, 15 balance weights, 16 oscillating cylinders.
The specific embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is done to further restriction, but should not be construed as limitation of the present invention:
Fig. 1 is structural representation of the present invention, as shown in the figure, liquid gravity shifts activation lever formula oil pumper, comprise horse head 1, lifting rope 2, lever 3, support 4, base 5, horse head 1 is connected with lever 3 front ends, lifting rope 2 is housed on horse head 1, and lever 3 is contained on support 4 by axis of centres bearing 6, and base 5 is arranged at support 4 bottoms.This is the structure of the former machine of oil pumper, by pumping of horse head, crude oil is extracted out.
The present invention also comprises pressure sensor 7, liquor pump 8, electric change valve 9, front fluid box 10, rear fluid box 11, encoder 12 and intelligent controller 13, wherein, pressure sensor 7 is arranged between the polished rod eye and pumping rod clip on lifting rope 2, and the pressure while moving up and down for perception horse head changes.Front fluid box 10 and horse head 1 are integrated design, rear fluid box 11 is positioned at lever 3 tail ends, between front fluid box 10 and rear fluid box 11, by pipeline, connect, and liquor pump 8 and electric change valve 9 are housed on the pipeline between front fluid box 10 and rear fluid box 11, therefore, by the driving of liquor pump 8 and electric change valve 9, liquid is moved around between front fluid box 10 and rear fluid box 11.Encoder 12 is connected on the jackshaft of axis of centres bearing 6, and pressure sensor 7 and encoder 12 are all electrically connected to the input of intelligent controller 13, and the output of intelligent controller 13 is electrically connected to liquor pump 8 and electric change valve 9.Therefore, intelligent controller 13, by receiving the signal of pressure sensor 7 and encoder 12, is then controlled the duty of liquor pump 8 and electric change valve 9.
When the present invention starts after operation, pressure sensor and encoder send the present status signals of this oil pumper to intelligent controller at any time, and intelligent controller is controlled the operating condition of liquor pump and electric change valve according to the status signals of receiving.When intelligent controller control liquor pump makes liquid, by pipeline, the front fluid box to horse head flows into, and horse head weight increases gradually, and rear fluid box weight reduces gradually, and under the effect of gravitational difference, horse head moves downward.Intelligent controller, according to the real-time required gravity situation of horse head, is controlled the flow that liquor pump is adjusted liquid at any time.When horse head approaches lower dead center soon, encoder sends signal to intelligent controller, intelligent controller is controlled electric change valve liquid flow direction is commutated, the liquid of front fluid box backward fluid box flows into, under the effect of inertia, horse head continues to move downward, the liquid of front fluid box continues fluid box backward and flows into, rear fluid box weight constantly increases, horse head weight constantly reduces, when horse head arrives after bottom dead center, horse head moves upward, equally, according to the real-time required gravity situation of rear fluid box, intelligent controller is controlled the transporting velocity that liquor pump is adjusted amount of liquid at any time.When horse head approaches top dead centre soon, intelligent controller is controlled electric change valve liquid flow direction is commutated, the liquid of rear fluid box flows into horse head, under the effect of inertia, horse head continues to move upward, the liquid of rear fluid box continues to flow into horse head fluid box, horse head weight constantly increases, rear fluid box weight constantly reduces, and when horse head arrives after top dead center, horse head starts to move downward ... go round and begin again, realize the continuous reciprocally swinging of horse head, thereby drive oil well pump constantly to move back and forth, realize the pumping to fluid.When liquid gravity shifts drive system and needs liquid feeding or fluid infusion, by liquid feeding car to this system add, fluid infusion.
Because pressure sensitive and Based Intelligent Control are prior art, at this, do not do further restriction, only illustrate.What the encoder in the present invention adopted is that model is E1040BT, manufacturer is the encoder that Huate Photoelectric Technology Co., Ltd., Changchun produces, what intelligent controller adopted is that model is SM20-30DC-ORC/30, manufacturer is the intelligent controller that Hangzhou Yingmaike Eclectronic Co., Ltd produces, as long as can realize the original paper of this control function, all can.
Between described lever 3 and support 4, safety plug 14 is also housed, can, by being fixed between lever and support, be convenient to shutdown maintenance.
Further, on described rear fluid box 11, balance weight 15 is also housed, for the gravity of balance rod string and oil column.
Fig. 2 is the structural representation of the second embodiment of the present invention, as shown in the figure, it is substantially identical with front a kind of liquid gravity transfer activation lever formula oil pumper with principle that this liquid gravity shifts activation lever formula Pumping Unit form, described liquor pump 8 is installed on the ground, is convenient to the repairing of liquor pump.On the described pipeline being connected with liquor pump 8, oscillating cylinder 16 is also housed, makes pipeline can swing drain.
Fig. 3 is the structural representation of the third embodiment of the present invention, as shown in the figure, it is substantially identical with the first liquid gravity transfer activation lever formula oil pumper with principle that this liquid gravity shifts activation lever formula Pumping Unit form, described front fluid box 10 and horse head 1 are for split designs, and front fluid box 10 is contained on lever 3 and is partial to a side of horse head 1.This kind of design is convenient to using mill type modification.
Oil pumper of the present invention is machinery-free driving-chain oil pumper, by liquid, in former and later two fluid boxes, flow and realize pumping of horse head back and forth, therefore some problems that machinery-free driving-chain brings, have increased substantially transmission efficiency, have increased substantially thus energy utilization rate; Can be according to underground working to horse head required gravity situation and motion law of suspension center requirement in real time, control intelligent weight-transfer system and adjust at any time the transfer velocity of gravity, realized by this condition requirement of down-hole work and carried out the supply as required of point-to-point power and speed, therefore have advantages of that power attenuation is little, further increased substantially energy utilization rate; This oil pumper is not only applicable to conventional stroke and jig frequency, is more suitable for long stroke and low jig frequency; This oil pumper has retained original base, support and lever, therefore just can on former oil pumper, transform, and transformation is convenient.
