Background technique:
Continuous development along with electronic technology, the birth of the DSP of high integrated high-speed makes the servocontrol of AC induction motor become possibility, Seeka company comprehensive Europe Japan advanced experience of the same trade, extract the patented technology of own intellectual property, flux linkage vector by the control motor, decompose stator current, make it to resolve into two components in torque and magnetic field, realize just joining even control through left side conversion.Thereby control can be controlled accurately to the parameters such as position, rotating speed, acceleration and output torque of AC induction motor.Seeka series screw pump servocontroller is with its superior control performance comprehensively, and low speed torque deficiency, heavily loaded lifting difficulty, the open-circuit excitation electric current that has overcome traditional frequency conversion control fully is excessive, harmonic pollution in electric power net serious, can not realize the detection of position, moment of torsion and control, narrow, the serial drawbacks such as realizing complex calculation and logic control of can't programming of velocity range.Thereby started new era of screw pump oil production control.But existing these advantages still can't satisfy present production needs, and the control of production requirement AC induction motor now and oil well condition adaptive ability are strong, function is more powerful.
The model utility content:
For control that solves production requirement AC induction motor now and the problem that the oil well condition adaptive ability is strong, function is more powerful, the utility model provides screw pump intelligence to transfer the ginseng servocontroller, this screw pump intelligence transfers ginseng servocontroller to transfer that ginseng science is convenient, power saving rate is high, have reverse-rotation preventing function, realize the soft start of screw pump and softly stop, the big torque characteristics of automaticity high, low speed, no-harmonic wave pollution.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of screw pump intelligence is transferred the ginseng servocontroller, mainly comprise tutorial light, start stop button, driver mainboard, data acquisition interface, encoder socket, malfunction alarm machine operation panel, air-break switch, touch screen, it is characterized in that: tutorial light is connected with the startup stop button, air-break switch is connected with the startup stop button, the driver mainboard is provided with data acquisition interface and encoder socket, malfunction alarm machine operation panel connects the driver mainboard, and touch screen connects the driver mainboard.
The beneficial effect of the utility model tool is:
1. transfer the ginseng science convenient, this servo-control system adapted touch screen carries out parameter adjustment to controller.In being provided with, the touch screen parameter can directly adjust parameter, and simple to operation.Precise speed control in the scope of full frame territory, velocity control accuracy can reach ± 0.1 ℅, speed adjustable range 1:5000, minimum operation speed 0.3 Zhuan ∕ branch.
2. power saving rate height.The encoder that can accurately measure motor speed has been installed in the system, servo drive can be according to the rotating speed of the geological condition timely adjustment screw pump in the situation of screw pump and oil field, make pump efficiency reach the highest, make system works, realize best energy utilization rate in the best production.Servo-control system can be brought up to the power factor of electrical network more than 0.9, reduces the reactive loss of screw rod greatly, improves energy-conservation level, is real green power supply.
3. reverse-rotation preventing function, this servo-control system has low-speed big output function and zero-speed lock shaft function, and the experiment that has pair busbar voltage to carry out because of systems soft ware detects, and by to detecting the measuring and calculating of motor output torque, screw pump is slowed down shut down.
4. realize soft start, soft the stopping of screw pump, reduce the mechanical shock that the start and stop of screw pump motor produce sucker rod, prolong the pump detection period of screw pump oil well, and can effectively prolong service life of equipment.
5. automaticity height; this system has power frequency, servo conversion function; it is the ideal product that improves screw pump automation, intelligent control; the excellent protection function; can realize protections such as the disconnected bar of overload, overcurrent, sucker rod, guarantee the safe in utilization of screw pump, perfect monitoring function the screw pump motor; overall monitor be can realize, revolution electric current, operating condition, power consumption etc. comprised the operating condition of screw pump.
6. low speed high torque characteristic solves the problem of traditional frequency conversion device low speed moment deficiency, heavy load starting difficulty, realizes zero to horizontal moment of torsion output between the rated speed, and the low speed load characteristic is good, can realize the stepless adjustment of 0 ~ rated speed.
7. no-harmonic wave pollution, system adopts space vector algorithm leading in the world, has suppressed the harmonic wave generation.System layout direct current reactor and large value capacitor are formed LC and are absorbed circuit, effectively stop harmonic wave to feed back to electrical network.
Description of drawings:
Fig. 1 is the utility model structural representation.
Tutorial light 1, startup stop button 2, driver mainboard 3, data acquisition interface 4, encoder socket 5, malfunction alarm machine operation panel 6, air-break switch 7, touch screen 8 among the figure.
Embodiment:
Below in conjunction with drawings and Examples the utility model is further specified.
A kind of screw pump intelligence is transferred the ginseng servocontroller, mainly comprise tutorial light 1, start stop button 2, driver mainboard 3, data acquisition interface 4, encoder socket 5, malfunction alarm machine operation panel 6, air-break switch 7, touch screen 8, it is characterized in that: tutorial light 1 is connected with startup stop button 2, air-break switch 7 is connected with startup stop button 2, driver mainboard 3 is provided with data acquisition interface 4 and encoder socket 5, malfunction alarm machine operation panel 6 connects driver mainboard 3, and touch screen 8 connects driver mainboard 3.
