Abstract
The present invention relates to a kind of simple pendulum variable-pitch beam-balanced pump, there is a simple pendulum device walking beam upper end, and the mid-stent of simple pendulum device is fixed a tooth bar guide rail, the fixedly connected motor in fork middle part, and described motor can move back and forth on the tooth bar guide rail; Also comprise a controller, detect load by controller, to Electric Machine Control, and then the bottom controlled, the balanced load that makes bottom balance weight produce can effectively play the effect in " peak clipping Pinggu " according to the needed balanced load real-time change of motor, makes the final load of motor keep constant, improved the efficient of motor greatly, energy-saving effect is remarkable.
Description
Technical field
The pumping unit that the present invention relates to use in the oil exploitation is specifically related to a kind of simple pendulum variable-pitch beam-balanced pump.
Background technology
The present most of oil well of China has entered machine and has adopted the stage.Adopt conventional beam-pumping unit because it is simple in structure, good reliability is convenient to advantages such as maintenance, is widely used in each elephant.Along with the increase of its quantity, the high shortcoming of its power consumption becomes increasingly conspicuous, and therefore the reducing energy consumption to beam pumping unit becomes a current main direction of studying.Beam pumping unit is because intrinsic quadric chain makes service load be similar to sinusoidal variation, and by the method for crank balance, its curve of load meets sinusoidal variation trend substantially; By increasing balance weight on the walking beam, make that the load change curve is smoother, but since at present the walking-beam counterweight that adopts all be fix or do simple the variation, thereby can not make oil pumper be in the maximum energy-saving state.
Summary of the invention
The object of the present invention is to provide a kind of simple pendulum variable-pitch beam-balanced pump, make the moment of slide block change along with the variation of polished rod load, finally make slide block moment original polished rod load be played the effect in " peak clipping Pinggu ", make motor finally be operated in constant force square state, thereby reach the purpose of maximum energy-saving.
A kind of simple pendulum variable-pitch beam-balanced pump of the present invention, there is a simple pendulum device its walking beam upper end, described simple pendulum device comprises two supports 5 and balance weight 8, the tie point of two supports 5 is fixed in fork 7 activities of fixedlying connected with balance weight 8, two support 5 middle parts are fixed with a tooth bar guide rail 4, the fixedly connected motor 6 in fork 7 middle parts, described motor 6 can move back and forth on tooth bar guide rail 4; Described beam pumping unit also comprises a controller 14, and controller 14 contains control chip, can detect, analyze, judge motor 13 load variations, and send control signal to motor 6, and then control single pendulum swing position.
Wherein detect the relevant parameter situation of change of motor 13 by controller 14, judge the suffered load change situation of motor, through software analysis, send instruction to motor 6, driven by motor single pendulum 8 is taken exercises along tooth bar guide rail 4, because the arm of force changes, the balancing load that single pendulum (balance weight) produces changes thereupon, and final " peak clipping Pinggu " of realizing motor load works under the constant load mode motor 13, improve the operating efficiency of motor, realized energy-conservation purpose.
Compared with prior art, the present invention works under the constant load mode motor 13, has improved the operating efficiency of motor, has realized energy-conservation purpose.
Description of drawings
Fig. 1 is the structural representation of simple pendulum variable-pitch beam-balanced pump.
The specific embodiment
As shown in Figure 1, the present invention includes polished rod eye 1, horse head 2, walking beam 3, tooth bar guide rail 4, single pendulum support 5, motor 6, fork 7, balance weight 8, support 9, connecting rod 10, crank 11, reducer 12, motor 13, controller 14, brake gear 15, base 16.
The present invention obtains the rear-mounted beam-pumping unit transformation of routine, add a simple pendulum device in the upper end of walking beam, the single pendulum end promptly is a balance weight 8, and single pendulum fork 7 middle parts connect firmly mutually with motor 6, motor 6 can move reciprocatingly along tooth bar guide rail 4, drives balance weight 8 and swings back and forth.
When down stroke, balance weight 8 is flapped toward right-hand member (in the face of drawing) gradually, can apply an extra load for motor 13 like this, thereby has avoided 13 actings of 2 pairs of motor of horse head.When horse head 2 suspension points were in bottom dead centre, balance weight 8 was flapped toward low order end, and the moment that makes balance weight 8 produce is maximum value, played " Pinggu " effect fully.
When upstroke, because a peak can appear in motor 13 load, balance weight 8 is swung to left end by low order end, and moving on tooth bar guide rail 4 by motor 6 provides power to drag, the moment that balance weight 8 produces reduces gradually, makes the load of motor 13 be unlikely to change excessive.When horse head 2 suspension points were in top dead-centre, balance weight 8 was in high order end, and the moment that makes balance weight 8 produce is minimum value, has played the effect of " peak clipping ".
In balance weight 7 swing process, detect the relevant parameter of motor 13 by controller, judge the value at instant load change curves place, by process analysis, the moment that calculating needs balance weight 8 to be produced, so control motor 6 drag single pendulum, make it be in appropriate position, the intrinsic motor load fluctuation of balance conventional pumping unit to greatest extent makes motor load be in the constant load state all the time.
