Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this kind oil sucking machine of compound permanent magnet motor does not have the code-disc positioning control system, comprise frequency converter 2 with pulse output function, the composite permanent magnetism motor 9 that drives of frequency converter and the electric control loop of composite permanent magnetism motor thus, wherein said control system comprises that also one is fixed on oil pumper and hangs buting iron 14 on heavy 6, and switches set 15 of forming by four limitation travel switches, be respectively the upstroke limitation travel switch from the bottom to top in the described switches set 15, up stroke anchor point correcting switch, down stroke anchor point correcting switch and down stroke limitation travel switch, be called XC2, XC4, XC3, XC1, described switches set 15 hangs heavy 6 adjacent in the same way layouts with oil pumper, and described buting iron 14 touches mutually with the interior switch of described switches set 15 during along catenary motion.The DIO3 mouth of described frequency converter 2 is programmed for the pulse delivery outlet by plug-in, its DIO2 mouth is programmed for the reception of impulse mouth by plug-in, both short circuits are set the number of pulses that the DIO2 mouth should receive in the frequency converter 2 by the plug-in of frequency converter 2 according to the vertical range between described up stroke anchor point correcting switch and the down stroke anchor point correcting switch and are exported in the electric control loop of composite permanent magnetism motor 9 as the sucker rod framing signal.The electric control loop of composite permanent magnetism motor 9 as shown in Figure 2.Described upstroke limitation travel switch, up stroke anchor point correcting switch, down stroke anchor point correcting switch and down stroke limitation travel switch are caused the electric control loop of composite permanent magnetism motor 9 respectively by holding wire, proofread and correct enabling signal, top correction enabling signal and top limit enabling signal as bottom limit enabling signal, bottom respectively.
Here, described frequency converter 2 adopts ABB AB, i.e. Asea Brown Boveri Ltd, production the ACSM1 frequency converter.During concrete the application, parameter 12.03 is set to 3,12.02 is set to 2 so just to have formed with DIO3 be pulse output, DIO2 as the pulse input from from the loop that connects.
The utility model is the mode of work-doing according to oil sucking machine of compound permanent magnet motor, and when rotating according to the frequency converter drive motors, sucker rod is whenever walked certain distance, and frequency converter can be exported with the corresponding pulse of sucker rod travel distance this thought and design.Be programmed for the pulse delivery outlet by DIO3 mouth with frequency converter, the DIO2 mouth is programmed for the reception of impulse mouth, by the number of pulses of the built-in Control Software of frequency converter, be converted into the distance of sucker rod walking, the no code-disc location of realizing oil pumper thus with the DIO2 mouth that receives.Wherein, because each location reference point all is last relatively anchor point, cumulative errors can appear, therefore XC3 is set and these two travel switches of XC4 are proofreaied and correct this cumulative errors, and according to the pre-set DIO2 mouth of the distance of XC3 and XC4 answer the received pulse number, make the operation area of sucker rod stable.When oil pumper moved, compound permanent magnet motor positive and negative both direction under the control of no code-disc positioning control system rotated, and realized that crude oil is extracted in the acting that moves up and down of sucker rod.
The buting iron that the suspension of no code-disc positioning control system control oil pumper is heavily gone up moves between XC3 and XC4, and the distance of operation is exactly the stroke of oil pumper, represent with L, and distance X C3 point and the XC4 distance of ordering is all between 2-3 centimetre, and this is apart from representing with M.When skew takes place in the location, revise by XC3 or XC4, guarantee that the operation area of sucker rod is stable.
It is as follows to use detailed process of the present utility model: after pressing the oil pumper start button, pumping-unit motor begins the frequency run with 2-3Hz, buting iron 14 is upwards operation under the drive of motor, when meeting XC3, motor begins reverse rotation and drives upwards operation of sucker rod, the rotation speed from 0Hz according to the acceleration and deceleration time that has configured, wherein equate accelerating time and deceleration time, accelerate to the speed of setting jig frequency, when speed reaches the rotating speed of setting spurt, control program is write down the umber of pulse N of DIO2 reception at that time, when the motor ramp to stop, in this section process that motor slows down, the DIO3 mouth of frequency converter does not send pulse, but owing to the acceleration and deceleration time of frequency converter is identical, so the distance of sucker rod walking is identical in the process of acceleration and deceleration, can converse the umber of pulse that equates with N, motor is in the running of upstroke like this, and the umber of pulse that the DIO3 mouth of frequency converter sends is exactly that the umber of pulse N that quickens the period is set the rotating speed umber of pulse Z of operation period.The sucker rod upwards distance of walking is L+M, and during the due umber of pulse N of the travel distance when the umber of pulse N+Z that receives when the DIO2 mouth adds and slows down, the theoretical umber of pulse of sucker rod walking is exactly Z+2N, and is corresponding with the distance L+M of sucker rod walking.When the umber of pulse that receives when the DIO2 mouth equals N+Z, control program sends the motor inverted command, frequency converter begins the operation of braking motor, make motor to quicken to stop the deceleration time of setting, and when the speed of motor is zero, begin to change direction and quicken rotation, sucker rod is moved downwards, and the process that whole process and sucker rod upwards move is in full accord.
Because the ability of frequency converter tolerance adverse circumstances is higher, so this kind of no code-disc positioning control system can not be subjected to the influence of oil pumper operational environment basically, can satisfy the positioning requirements of oil pumper fully, and can the correction of timing deviations by the position correction travel switch, compare with the code-disc navigation system, precision still increases.And owing to do not re-use the expensive encoder of price, the no code-disc positioning control system of this kind is compared with the code-disc navigation system is arranged, and its manufacturing cost and maintenance cost all are lowered far away.
