A kind of oil pumper dynamic energy saving device
Technical field
The present invention relates to a kind of energy saver, specifically a kind of oil pumper dynamic energy saving device, belongs to energy-saving electric machine applied technical field.
Background technology
Oil pumper is a kind of machinery equipment of recover petroleum, and common oil pumper and beam pumping unit are traditional pumping units of oil field extensive use, are usually directly dragged by ordinary ac asynchronous motor.Its crank band drives sucker rod with balance, downhole pump is driven to fix pumping of cycle, the oil of down-hole is delivered to ground, in a jig frequency, along with rising or the decline of sucker rod, and making machine operation at electronic or generating state, uphill process motor absorbs energy electric operation from electrical network, the load characteristic of decline process motor is potential load, in addition DH negative pressure etc. make motor be in generating state, mechanical energy is converted to electric energy feedback to electrical network, but, the situation of down-hole oil reservoir is complicated especially, there is rich oil well, dividing of stripper, there is thin oil well, heavy oil wells is not, constant speed application problem is apparent, piston after wearing and tearing and the gap leaking loss etc. of lining are all very scabrous problems, moreover the formation factor of change is as contained sand in oil, wax, water, the complex situations such as gas also have a great impact the oil mass that every jig frequency is extracted out, therefore, for the problems referred to above, a kind of oil pumper dynamic energy saving device is proposed.
Summary of the invention
Have problems for above-mentioned prior art, the invention provides a kind of oil pumper dynamic energy saving device, the power-saving technique of oil pumper adopts variable frequency regulating speed control, change the state that oil pumper is in poor efficiency acting for a long time, its working method and oil well actual load are matched, realizes dynamic energy-saving in this way.
For achieving the above object, the technical solution used in the present invention is: a kind of oil pumper dynamic energy saving device, comprises base, and described base top arranges support and cantilever tip arranges center bearing seat; Described center bearing seat outer setting walking beam, and walking beam right-hand member arranges horse head; Described horse head sidewall arranges polished rod eye; Described walking beam left end installs crossbeam and crossbeam is connected with the balance weight being arranged on base top by connecting rod; Fixed by crank-pin between described balance weight and connecting rod, and balance weight right-hand member arranges reducer; Described reducer is connected with the motor be fixed on base; On the right side of described motor, brake button is set and motor controls by being arranged on frequency conversion box on base.
Further, also comprise crank, described crank is fixed on reducer, and crank (10) is connected with balance weight.
Further, described horse head is arc-shaped structure, and horse head arranges ellipsoidal structure.
Further, described oil pumper realizes dynamic energy-saving by the rotating speed of inverter control motor, and motor is provided with sensor live signal is fed back to intelligent controller regulates frequency converter by intelligent controller.
The invention has the beneficial effects as follows: the power-saving technique of oil pumper adopts variable frequency regulating speed control, change the state that oil pumper is in poor efficiency acting for a long time, its working method and oil well actual load are matched, ensure all to pump at every turn, reduce the even invalid extraction of poor efficiency, thus reduce electricity charge spending, reduce maintenance cost, improve operational efficiency.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Figure of description 1 ~ 2, in the present embodiment, comprise base 1, described base 1 top arranges support 2 and support 2 top arranges center bearing seat 6; Described center bearing seat 6 outer setting walking beam 5, and walking beam 5 right-hand member arranges horse head 4; Described horse head 4 sidewall arranges polished rod eye 3; Described walking beam 5 left end installs crossbeam 7 and crossbeam 7 is connected with the balance weight 9 being arranged on base 1 top by connecting rod 8; Fixed by crank-pin 15 between described balance weight 9 and connecting rod 8, and balance weight 9 right-hand member arranges reducer 11; Described reducer 11 is connected with the motor 12 be fixed on base 1; On the right side of described motor 12, brake button 14 is set and motor 12 is controlled by the frequency conversion box 13 be arranged on base 1.
As optimisation technique scheme of the present invention: also comprise crank 10, described crank 10 is fixed on reducer 11, and crank 10 is connected with balance weight 9; Described horse head 4 is arc-shaped structure, and horse head 4 arranges ellipsoidal structure; Described oil pumper realizes dynamic energy-saving by the rotating speed of inverter control motor 12, and motor 12 is provided with sensor live signal is fed back to intelligent controller regulates frequency converter by intelligent controller.
As operating principle of the present invention: it is less that frequency converter has electric current when soft start function starts, impact little to electrical network, during starting, energy consumption greatly reduces, avoid sizable rated current during startup, avoid unnecessary electric energy loss, consumption decreases motor simultaneously, gearbox, the impact of the large machinery such as oil pumper, extend the application life of relevant device, introduce Frequency Converter Control can realize on equipment, down stroke automatically identifies thus controls on petroleum extractor, the motor running frequency of down stroke is adjustable respectively, to change on oil pumper, the speed of service of down stroke, solve the stopping production caused because changing belt pulley speed governing, thus improve production efficiency, reach when meeting pump efficiency simultaneously and consume minimum electric energy, due to oil pumper descending time load characteristic be potential load, its operating mode be able to be adapted to after frequency converter installs dynamic braking function additional, great convenience is brought for change oil pumper rotational speed regulation optimum Working, simultaneously, realize the dynamic energy-saving of oil pumper.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present invention; not in order to limit the present invention, every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solution of the present invention.
