Abstract
The invention provides an integrated permanent magnet stepless speed regulating device of an oil pumping unit. The device adopts permanent-magnet machine as the power of beam-pumping unit, and the walking beam top is equipped with initiative compensation arrangement, is equipped with servo motor driven lead screw on the initiative compensation arrangement base, lead screw trapezoidal thread connection balancing weight, and the balancing weight passes through the guide rail slide with initiative compensation arrangement's base to be connected, is equipped with position sensor on the support of walking beam below, and the polished rod eye top is equipped with pressure sensor, and each sensor, motor all have the wire to connect variable frequency control cabinet. The walking beam type oil pumping unit realizes two speeds of ascending and descending in one working cycle, namely, the speed is fast in the upper part and slow in the lower part, sufficient filling time is provided for the oil well pump, the liquid production capacity of each cycle is improved, and the efficiency of a mechanical oil extraction system is improved; the permanent magnet motor is efficient and energy-saving, and the power consumption is reduced along with the reduction of the speed during the downward movement, so that the energy-saving effect is obvious; the active compensation device is adopted to actively compensate the pressure change of the pumping unit in the stroke completion process, and the production efficiency is improved.
Description
Technical field:
The present invention relates to oil extraction in oil field equipment field, particularly relate to a kind of oil pumper integrated permanent-magnet stepless time adjustment device.
Background technology:
Current walking-beam pumping unit mainly adopts the direct driving style of asynchronous motor, in application process, also there is following problem: one pumping-unit motor speed governing difficulty, in one-period, up and decline a rotating speed, can not in a swing circle adjusting stroke frequency.Two is that the efficiency of asynchronous machine is low, energy consumption large, and this is the feature of asynchronous machine itself.Be three be that starting moment is little, need the motor of relatively high power to meet and start requirement, operate power is less again, causes the phenomenon of low load with strong power, adopts energy-conservation, adjustable parameter actuator to substitute the trend that original asynchronous machine is the development of oil recovery actuator.
Summary of the invention:
The object of the invention is to solve by oil pumper integrated permanent-magnet stepless time adjustment device the problems referred to above run in walking-beam pumping unit operational process.
Technical scheme of the present invention is: oil pumper integrated permanent-magnet stepless time adjustment device, device adopts magneto as the power of oil pumper, comprise walking beam on pumping units, active compensation device is provided with above walking beam, active compensation device base is provided with the leading screw of driven by servomotor, leading screw acme thread connects balancing weight, balancing weight is connected by guide rail slideway with the base of active compensation device, support below walking beam is provided with position transducer, the poliched rod eye top of oil pumper is provided with pressure transducer, position transducer, pressure transducer, servomotor and magneto all have wire to be connected frequency-conversion control cabinet.
The present invention has following beneficial effect: walking-beam pumping unit is in the one-period of work, realize up and two speed that decline, both gone up fast lower slow, such benefit is, to the TPER that oil well pump is enough, effectively avoid the phenomenon of original each cycle Liquid output deficiency, improve the Liquid output in each cycle, extend the oil well overhaul cycle, improve computer collecting system efficiency; Magneto is inherently energy-efficient, and add descending hourly velocity and reduce, consumed power also decreases, and energy-saving effect is remarkable; Adopt active compensation system, the pressure change of Active Compensation oil pumper in stroke complete process, enhances productivity.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present invention.
1-magneto in figure, 2-walking beam, 3-servomotor, 4-leading screw, 5-balancing weight, 6-position transducer, 7-frequency-conversion control cabinet, 8-pressure transducer, 9-poliched rod eye, 10-active compensation device.
Embodiment:
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, oil pumper integrated permanent-magnet stepless time adjustment device adopts magneto 1 as the power of oil pumper, comprise walking beam on pumping units 2, active compensation device 10 is provided with above walking beam 2, active compensation device 10 base is provided with the leading screw 4 that servomotor 3 drives, leading screw 4 acme thread connects balancing weight 5, balancing weight 5 is connected by guide rail slideway with the base of active compensation device 10, support below walking beam 2 is provided with position transducer 6, poliched rod eye 9 top of oil pumper is provided with pressure transducer 8, position transducer 6, pressure transducer 8, servomotor 3 and magneto 1 all have wire to be connected frequency-conversion control cabinet 7.
Oil pumper integrated permanent-magnet stepless time adjustment device is adopted directly to replace original asynchronous machine, compared with original oil pumper asynchronous machine device, oil pumper integrated permanent-magnet stepless time adjustment device sharpest edges are exactly to carry out the adjustment of jig frequency in a swing circle of walking-beam pumping unit, up and lower property two rotating speeds, both gone up fast lower slow, all speed regulation processes by frequency converter according to position transducer 6, the signal of pressure transducer 8, frequency-conversion control cabinet 7 sends the action of instruction determination servomotor 3, leading screw 4 is driven to rotate, balancing weight 5 is the mobile transient equilibrium reaching Active Compensation walking beam 2 on walking beam 2, adapt to the pressure change of the sucker rod that a variety of causes causes, automatic identification completes, without the need to manual shift, intelligence degree is higher, safe and reliable, energy-saving effect is remarkable.
