Technical field
The utility model relates to a kind of conventional beam-pumping unit self-balancing energy-saving control device, belongs to petroleum machinery extracting device of oil technical field,
Background technology
At present, domestic is reduce oil pumper energy consumption problem to take multinomial way.One is conventional pumping unit is carried out reducing energy consumption in batches, as being transformed into double-horsehead pumping unit, down-eccentric barbell type pumping unit etc.Two is install energy-saving actuator additional to conventional pumping unit, implements reducing energy consumption.Three is install couple capacitors reactive power additional in oil pumper electrical control cubicles to carry out local compensation or attached with frequency converters, reduces reactive power.But above method all can not reach good energy-saving effect in practical application.The many energy-saving beam pumping unit of external Developing Application, in oil recovery practice, has a better effect.As become trimming moment oil pumper, but upstroke trimming moment is greater than down stroke trimming moment.Forward type air balanced pumping unit, owing to can regulate gas counterbalance effect better in a dynamic state.In addition abroad still further developed as air bag balanced oil extractor, Pumping Units, front beam-pumping unit, forward type balanced oil extractor, autobalance oil pumper, short oil pumper, ROTAFLEX oil pumper, screw pump oil production system etc. obtain good energy-saving effect in actual applications.
Summary of the invention
The utility model object is to overcome the deficiencies in the prior art, provides a kind of conventional beam-pumping unit self-balancing energy-saving control device, and when being changed by the balance and underground working realizing crossbeam, the automatic adjustment of jig frequency, reaches energy-conservation object.For solving current oil field beam pumping unit balanced adjustment difficulty, the problem that production fluid is low with input power ratio, the operating efficiency of raising oil pumper, saves the object of a large amount of electric energy.
The technical scheme that the utility model adopts is:
A kind of conventional beam-pumping unit self-balancing of the utility model energy-saving control device, primarily of balance weight, stand-by motor, angular transducer, load transducer, control system, crossbeam elongation end, balance block fixing structure, steel wire tow line composition.Described crossbeam elongation end is welded on crossbeam left end, and stand-by motor is by chute and be bolted on crossbeam; The length of crossbeam elongation end, balance block fixing structure and the weight of balance weight all obtain by the EQUILIBRIUM CALCULATION FOR PROCESS analysis of crossbeam; Balance block fixing structure is arranged on in the rotating shaft of crossbeam elongation end left end, simultaneously and weld together with balance weight.Angular transducer is directly installed on the turning cylinder of walking beam.
Crossbeam tail end increase balance weight, when cross beam water at ordinary times, equal the moment of balance weight to walking beam fulcrum by making the moment of the average of load suffered by horse head suspension point to walking beam fulcrum; Utilize load transducer and rotary angle transmitter, calculate the real-time indicator card of oil pumper, the indicator card data obtained are passed to control system, after exceeding setting value if there is degree of unbalancedness, control system controls the balance weight that stand-by motor regulates crossbeam afterbody, reaches relative equilibrium; If there is hydraulic pressure during not enough or down-hole fault, control reduction jig frequency or the shutdown of oil pumper, take out to solve sky, the FAQs such as liquid deficiency, underground equipment fault.
The utility model has carried out Curve guide impeller to crossbeam on the basis of conventional beam-pumping unit, adds balance weight, stand-by motor, angular transducer, load transducer, control system, frequency converter parts.
The utility model has the advantages that: the adjustment counterweight balancing device 1, by automatically measuring, effectively can solve counterweight in beam pumping unit running and regulating problem, reaching long-term work at relative balance state, thus reach energy-conservation object; 2, by the Measurement and analysis of indicator card, control the frequency converter work of oil pumper in real time, reduce the FAQs such as sky is taken out, liquid is not enough, improve the utilization of the energy, reach energy-conservation object.3, pass through direct for load transducer clamping in polished rod, just can realize the measurement of sucker rod loading force, solve the problem that fluctuating load damages sensor.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, a kind of conventional beam-pumping unit self-balancing of the utility model energy-saving control device, forms primarily of balance weight 3, stand-by motor 4, angular transducer 7, load transducer 9, control system 10, crossbeam elongation end 12, balance block fixing structure 13, steel wire tow line 14.Described crossbeam elongation end 12 is welded on crossbeam 5 left end, and stand-by motor 4 is by chute and be bolted on crossbeam 5; The length of crossbeam elongation end 12, balance block fixing structure 13 and the weight of balance weight 3 all obtain by the EQUILIBRIUM CALCULATION FOR PROCESS analysis of crossbeam 5; Balance block fixing structure 13 is arranged on in the rotating shaft of crossbeam elongation end 12 left end, simultaneously and weld together with balance weight 3; Angular transducer 7 is directly installed on the turning cylinder 11 of walking beam.
The basis of conventional beam-pumping unit increases balance weight 3, stand-by motor 4, angular transducer 7, load transducer 9, control system 10, crossbeam elongation end 12, balance block fixing structure 13, steel wire tow line 14.
When oil pumper works, the data recorded in real time when load transducer 9 and angular transducer 7 calculate and analyze indicator card, judge the duty of now oil pumper via control system 10 process, analyze the degree of balance of oil pumper work, down-hole feed flow abundance is no, during the FAQs such as sky is taken out, pump valve fault, time not enough if there is feed flow, control system 10 regulates the frequency converter be connected with mair motor 1, and the rotating speed of mair motor 1 is reduced, reach and completely take out, reduce electric energy loss; When transfiniting if there is the degree of balance, control system 10 calculates the maximum energy-saving position of adjustment block 3 automatically, then by regulating stand-by motor to arrive corresponding position, thus play energy-conservation object.Control system 10 is critical pieces of this device, it is mainly through the indicator card of computational analysis oil pumper, draw each and kind exception in oil pumper work and fault, carry out accelerating with the frequency converter operating oil pumper, reduction of speed, the work such as stopping, also to calculate the degree of balance of oil pumper itself simultaneously, control and regulate the counterweight of oil pumper.
