Abstract
The utility model discloses an oil pumping machine, which comprises a motor, a machine shaft, a machine frame, a balance weight block, a pump rod and a control device. The utility model is characterized in that the motor is a compound permanent magnetic motor; the radial cylinder surface of a rotor of the compound permanent magnetic motor is wound with a steel cable for traction; one rope end a of the steel cable is connected with the pump rod of an oil pump, and the other end b is connected with a balance weight box; a motor rotor moves repeatedly for driving the pump rod to lift and pull upwards and downwards. Because the utility model adopts the compound permanent magnetic motor with large power density, the structure of the utility model is simplified and the utility model has convenient installation and maintenance. The utility model is suitable for the renewal of equipment of oil pumping machines in oil fields.
Description
Technical field
The utility model belongs to the equipment that extracts oil from oil well.Specifically a kind of pumping unit that drives with compound permanent magnet motor.
Background technique
The oil industry is key pillars of the national economy, the petroleum production task is heavy, equipment is worked continuously, and produce the traditional pumping unit that adopts at present is the slide beam structure, because rotating speed is slow, adopt common electric machine to need large speed ratio to slow down, and the structure of big moment gear reduction box is very huge, complicated, so that whole work efficiency is not high.Because pumping unit is the basic equipment in oil field, consumption is very big, and continuous firing has accounted for very big proportion in the total energy consumption in oil field.In fact, Fu Za structure has been enough to make the reliability reduction and the cost of equipment maintenance of complete machine work to increase virtually much.
Summary of the invention
For working efficiency and the performance that improves pumping unit, the utility model provides a kind of pumping unit that drives with compound permanent magnet motor from simplified structure.
Oil sucking machine of compound permanent magnet motor of the present utility model, comprise motor, arbor, frame, balancing weight, pump rod and control gear, it is characterized in that said motor is a compound permanent magnet motor, radially tube face at the compound permanent magnet motor rotor is wound with the traction wirerope, end a of wirerope connects the pump rod of oil well pump, the other end b connects a ballast box, drives pump rod pull lift action up and down by the rotor to-and-fro motion.
Described compound motor, the end face of its at least one side (rotor) also is provided with the gudgeon cover, is provided with bearing between gudgeon cover and arbor, and wirerope puts around gudgeon.
The utility model is owing to adopted the big compound permanent magnet motor of specific power, under the direct drive of its rotor, work, oil pumping pump rod and counterweight by the direct balanced oil extractor of twisted rope wirerope, drive pump rod, like this, removed traditional walking beam, horse head and complicated gear reduction box mechanical structure, shortened Transmitted chains, overall efficiency is greatly improved.Install, safeguard all more convenient.
Description of drawings
Fig. 1 is the structural representation of oil sucking machine of compound permanent magnet motor.
Fig. 2 is the oil sucking machine of compound permanent magnet motor structure embodiment who is provided with the gudgeon cover.
Wherein: 1, motor 2, arbor 3, frame 4, wirerope (twisted rope) 5, gudgeon cover
Embodiment
Compound permanent magnet motor is a kind of magneto new product of combined type of compact structure.Structural principle is: use the stator of disc type and p-m rotor to constitute two symmetrical card motor independent driving units, between these two driver elements, add the 3rd the external motor of common rotor, make the motion portion of three independent driving units form one, reduce volume, the purpose that reduces cost to reach under the certain situation of electric power.When stator coil passes to Ac, produce a rotating magnetic field, make a concerted effort to promote the p-m rotor rotation, output torque at motor gas-gap.
Be further described below in conjunction with embodiment and accompanying drawing thereof:
Referring to accompanying drawing.
Oil sucking machine of compound permanent magnet motor shown in the accompanying drawing 1, comprise motor 1, arbor 2, frame 3, balancing weight, pump rod and control gear, its motor is a compound permanent magnet motor, radially tube face at the compound permanent magnet motor rotor is wound with traction wirerope 4, end a of wirerope connects the pump rod of oil well pump, the other end b connects a ballast box (not expressing among the figure), drives pump rod pull lift action up and down by the rotor to-and-fro motion, thereby from the extracted downhole oil.
Shown in Figure 2, the both sides end face of compound rotor (at least one end) is equipped with gudgeon cover 5, is provided with the bearing of carrying usefulness between gudgeon cover 5 and arbor in addition, and wirerope puts around gudgeon.So just the wirerope on Fig. 1 can be moved on on the gudgeon of one or both sides, output effect is the same from the ear muff, but the size of front and back ballast box and pump rod position is then reduced.
During work, three independent driving units of this motor start simultaneously, and rotor makes a concerted effort to move, control commutation under the frequency that variable-frequency governor is set.When the stator coil of motor passes to the Ac of certain frequency, will produce a rotating magnetic field at the motor gas-gap position, make p-m rotor rotary work under the effect of air-gap field.By output mechanism,, drive (driving) load operation from the end a of wirerope.
The compound permanent magnet motor of this used for oil extractor, its external rotor is composited by two symmetry card rotor and cartridge type rotors in parallel, and the card space is big, is fit to low-speed and large-torque output, is convenient to be equipped with type selecting; Its structural design in parallel makes that the complete machine size is less, is more convenient for processing because of the flat open structure of card, and cost is reduced.
