The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
A kind of intelligent hydraulic pumping unit, form by the hydraulic power unit 12 that is complementary with it, in the sleeve pipe 17 of oil pumper, be provided with pump barrel 5, be provided with hollow rod 4 in the pump barrel 5, be provided with hydraulic cylinder 2, following hydraulic cylinder 11 on the hollow rod 4, pump barrel 5 is between last hydraulic cylinder 2 and following hydraulic cylinder 11; Be provided with plunger 7 at the middle part of hollow rod 4, epicoele move about one way valve 6, cavity of resorption move about one way valve 8 be located on the hollow rod 4, in the above and below of plunger 7; Do not hold in the bottom of hollow rod 4 and to be provided with one way valve 13; At last hydraulic cylinder 2, down be respectively equipped with the fixedly fixing one way valve 10 of one way valve 3, cavity of resorption of epicoele between the hydraulic cylinder 11 on the pump barrel 5; Last hydraulic cylinder 2 is connected with hydraulic power unit 12 by hydraulic system high-pressure pipeline 9 with following hydraulic cylinder 11.
Be provided with oil pipe 14 below the above-mentioned following hydraulic cylinder 11, oil pipe 14 forms cavity with hollow rod 4, is provided with bottom valve 15 in the bottom of oil pipe 14.
The top oil outlet end of above-mentioned hollow rod 4 is provided with one way valve 18.
The pipeline of above-mentioned hydraulic power unit 12 is provided with heater.
Above-mentioned heater can be phase transition of vacuum heat abstractor 16.
Be provided with heating and working media in the above-mentioned phase transition of vacuum heat abstractor 16.
On last hydraulic cylinder 2, be provided with flowline 1.
Hydraulic power unit of the present invention is a prior art.
Operating principle of the present invention: at first start hydraulic system oil pump, Adjustment System pressure, jig frequency, stroke and oily temperature control etc.Plunger 7 constitutes upper and lower two working chambers independently in pump barrel 5, with two hydraulic cylinders on the hollow rod 4 is power, drive synchronously the 7 upper and lower motions of oil pumper plunger, in up-down stroke upper and lower chamber finish respectively into, oil extraction, pump continuously thereby reach total travel.
Oil pumper is when upstroke, plunger 7 rises, this moment, bottom valve 15 was opened, oil enters down the inner chamber of the oil pipe 14 below the hydraulic cylinder 11, cavity of resorption on the hollow rod 4 one way valve 8 and the one way valve 13 that move about closes valves, and with hollow rod 4 risings, pump letter this moment 5 cavity of resorptions produce negative pressure, be placed on the pump barrel 5 cavity of resorption fixedly one way valve 10 open, the oil that sleeve pipe 17 and pump barrel are 5 enters cavity of resorption, and the oil in pump barrel 5 epicoeles is because plunger 7 compression pressures raise, and the epicoele of the epicoele one way valve 6 that moves about is opened, oil enters hollow rod 4 inner chambers, and the epicoele of epicoele fixedly one way valve 3 is closed.Oil passes hydraulic cylinder 2 and enters the oil pumping process that flowline 1 has been finished upstroke from hollow rod 4.The commutation of hydraulic cylinder (2,11) is to lean on the photocontrol of hydraulic power unit 12 to realize.
Oil pumper bottom valve 15 when down stroke cuts out, hollow rod 4 below the following hydraulic cylinder 11 is descending, the pressure of oil pipe 14 inner chambers raises, being contained in one way valve 13 on the hollow rod 4 opens oil and enters hollow rod 4 and upwards flow, at this moment because the pressure rising by compression of the cavity of resorption oil of the descending pump barrel 5 of plunger 7, the cavity of resorption one way valve 8 that moves about is opened, the cavity of resorption of cavity of resorption fixedly one way valve 10 is closed oil and is entered hollow rod 4 inner chambers, passes plunger 7, goes up the oil pumping process of hydraulic cylinder 2 when hollow rod 4 enters flowline 1 and finished down stroke.Thereby the purpose of oil pumping continuously when having reached the upper and lower stroke of oil pumper.
Driven by motor oil pump in the hydraulic power unit is extracted oil out from fuel tank through filter, can adjust system pressure by overflow valve.The phase transition of vacuum heat abstractor is housed in fluid pressure line, the heat conduction temperature can raise rapidly when the heating work medium, therefore in hydraulic oil pumping work, also improved the temperature in the oil well, thereby solved the problem that when heavy oil wells is recovered the oil, need heat breakthroughly.The opening pressure of the one way valve 22 shown in the figure is greater than the pressure of one way valve 19, when oil return one way valve 19 at first conducting to phase transition of vacuum phase heat abstractor fuel feeding, one way valve 22 conductings oil oil sump tank then.When hydraulic pressure commutated, the operating principle of one way valve (20,21) was identical with the operating principle of one way valve (19,22).Thereby guarantee the loss of conduction oil in the phase transition of vacuum heat abstractor.
