Description
Technical field
The utility model relates to a kind of pumping unit of well oil recovery bar elevating control cabinet, particularly a kind of intelligent double speed oil well frequency-conversion control cabinet.
Background technology
Motor of pumping unit is energy-conservation should comprise two aspects: the one, from motor itself, consider, and improve load factor and the efficiency of motor; The 2nd, from system, consider, change the mechanical property of motor, make machine, bar, pump whole system reach good cooperation, improve system effectiveness.Both compare, and the latter's energy-saving potential is more much bigger than the former, is the energy-conservation subject matter of motor of beam-pumping unit.Facts have proved, on oil field equipment, apply not only automaticity raising of frequency conversion control technique, energy-saving effect is obvious, and adjusts ginseng convenient, reduces workload, and comprehensive benefit is remarkable.
In oil recovery production process, due to the impact of the factors such as the thick wax deposition of oil, cause polished rod descending slowly at present, Fang Kazi and polished rod eye disconnect, up-down stroke load variations is widely different, causes equipment operation not steady, and mechanical accident easily occurs, and electric weight waste greatly, in process of production, when descending, sucker rod can bend oil well in oil pipe simultaneously, and side-abrasion of rod string is serious, and the coefficient of fullness of pump is low, when up, between pump barrel and piston, can miss.This all causes its motor need to expend larger electric energy.
Summary of the invention
In order to solve the problem of prior art, the utility model provides a kind of intelligent double speed oil well frequency-conversion control cabinet, reasonable in design, novel structure, safe and reliable, high in technological content, thoroughly having solved square clamp and polished rod eye disconnects, the problem that up-down stroke load variations is widely different, extend pump detection period, improved oil well output, there is good promotional value.
The technical scheme that the utility model adopts is as follows:
A kind of intelligent double speed oil well frequency-conversion control cabinet, comprise the motor of controlling oil-extractor polish-rod and polished rod eye lifting, motor is electrically connected to upstroke speed control circuit and down stroke speed control circuit by control chip, and described control chip is also electrically connected to upstroke approach switch and down stroke approach switch.
Control chip is also electrically connected with brake unit.
Upstroke speed control circuit or down stroke speed control circuit consist of work frequency circuit and frequency changer circuit respectively, and described work frequency circuit and frequency changer circuit are realized and being switched by change over switch.
A kind of intelligent double speed oil well frequency-conversion control cabinet of the present utility model, is mainly comprised of intelligent frequency convertor, A.C. contactor, air switch, portable DJ frequency variation signal transmitter, fixed DJ frequency variation signal transmitter, housing and wire.
The principle of intelligence double speed oil well frequency-conversion control cabinet volume increase:
Within a work period, have two operating characteristic, the upstroke speed of service is fast, and the slow mode of the down stroke speed of service is moved.Reduce the time that oil pumper sky is taken out, improve pump efficiency, thereby energy savings increases output.
Intelligence double speed oil well frequency-conversion control cabinet is that the operating characteristic of oil pumper up-down stroke is undergone technological transformation, and its working method is on the intelligent frequency convertor working panel of control cubicle, to have two knobs, is used for setting the rotating speed of upstroke and the rotating speed of down stroke.By position transducer, detected the position of beam hanger for pumping machine, thus beginning and the end of judgement oil pumper up-down stroke.
During oil pumper operation, when polished rod eye moves to bottom dead centre, position transducer passes to intelligent frequency convertor by signal, upstroke starts the rotary speed instruction that frequency converter is carried out upstroke, when polished rod eye moves to top dead-centre, down stroke starts the rotary speed instruction that frequency converter is carried out down stroke, thereby realizes the operational mode of two speed of a stroke, and the slow operational mode of the fast down stroke of upstroke.
Application Based Intelligent Control has following features
1. arrange pumpingh well working system, start by set date, stop, realizing soft starter for motor, to electrical network without impact.
2. regulate the stroke frequency of oil pumper.Along with oil well extraction from the superficial to the deep, the situation that pump efficiency declines, will inevitably appear that the degree of filling of pump is not enough, in the minimizing of down-hole oil mass.When the fluid supply capacity of oil well is less than oil pumping pump delivery, just may cause pump depletion and liquid hammer.One of effective ways that prevent liquid hammer are to slow down pump speed to improve pump degree of filling.By variable-frequency control technique, reduce motor speed and reduce the extraction frequency, not only reduced power of motor, and improved the degree of filling of pump, greatly improve pump efficiency, increase crude output.
3. regulate the speed of the upper and lower stroke of oil pumper.Adopt intelligent variable-frequency speed adjusting technique, except can changing the stroke frequency of oil pumper, can also adjust respectively according to actual needs the speed of every one-stroke up-downgoing journey, make oil pumper be operated in optimal operational condition.In every one-stroke, suitably reduce the speed of down stroke, can improve the degree of filling of crude oil in pump, and suitably improve the speed of up stroke, can reduce the leakage factor in lifting, effectively improve crude output in the unit interval, by regulating, also can greatly save the consumption of electric energy simultaneously.
The beneficial effect that the technical scheme that the utility model provides is brought is:
1, solved in oil recovery production process, due to the impact of the factors such as the thick wax deposition of oil, caused polished rod descending slowly, square clamp and polished rod eye disconnect, and up-down stroke load variations is widely different, causes equipment operation not steady, and the problem of mechanical accident easily occurs.
2, descending slowly owing to having solved polished rod, square clamp and polished rod eye disconnect, and the problem that up-down stroke load variations is widely different, so saved a large amount of electric weight.
3, due to oil well in process of production, when descending, sucker rod can bend in oil pipe, side-abrasion of rod string is serious, and the coefficient of fullness of pump is low, but when down stroke is slower than upstroke, sucker rod downstream rate slows down, sucker rod degree of crook in oil pipe reduces, the degree that has reduced side-abrasion of rod string, has extended pump detection period.
4, due to oil well in process of production, when down stroke is slower than upstroke, being full of of pump is rising, wastage when upstroke is fast between pump barrel and piston reduces, and has improved pump efficiency, has increased output.
