Background technology
The oil industry is key pillars of the national economy, the oil exploitation task is heavy, equipment is worked continuously, and produce the traditional oil pumper that adopts at present is the beam type structure, because rotating speed is slow, need the motor large speed ratio to slow down, the structure of big moment gear reduction box is very huge, complicated, and whole work efficiency is not high.Because oil pumper 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 of complete machine work to reduce and the cost of equipment maintenance increase.
Summary of the invention
For operating efficiency and the performance that improves oil pumper, the utility model provides a kind of oil pumper that utilizes permanent-magnet disc motor directly to drive from simplified structure.
The direct drive-type oil pumper of permanent-magnet disc motor of the present utility model, comprise motor, support, balancing weight, pump rod and control device, it is characterized in that said motor is the permanent-magnet disc motor of twin symmetrical structure, the stator of motor and rotor are flat tray type structure, rotor, stator are parallel to each other and are provided with air gap, and card vertically is installed on the main shaft of rotor; This main shaft is provided with winch spool, and winch spool is provided with twisted rope, and an end of twisted rope connects pump rod, and the other end connects balancing weight, directly drives winch spool work by the main shaft of motor.
Stroke when described winch spool back and forth rotates is consistent with the impulse stroke of pump rod.
The utility model is because the mode that adopts electric machine main shaft directly to drive, drive oil pumping pump rod and the counterweight of back by winch spool on the electric machine main shaft and the direct balanced oil extractor of twisted rope, affect twisted rope back and forth to move, like this, walking beam, horse head and complicated gear reduction box frame for movement have been removed, shortened driving-chain, overall efficiency is greatly improved; Because the card space is big, especially be convenient to the design of low-speed and large-torque output; Then be equivalent to the effect of two motors along the structure of major axes orientation parallel connection, help dwindling physical dimension; Flat open structure then is convenient to processing, and installation and maintenance is also very convenient.

The specific embodiment
Be further described below in conjunction with embodiment and accompanying drawing thereof:
Referring to accompanying drawing 1,2,3.
The direct drive-type oil pumper of permanent-magnet disc motor of the present utility model, comprise motor 1, support 5, balancing weight 6, pump rod 9 and control device, it is characterized in that said motor is the permanent-magnet disc motor of twin symmetrical structure, the rotor 10 and the stator 12 of motor are flat tray type structure, rotor 10, stator 12 are parallel to each other and are provided with air gap, card vertically is installed on the main shaft 2 of rotor, the epitrochanterian permanent magnetic steel 11 of card (utmost point) is along the card circle distribution, and is corresponding with the armature winding 13 on the stator; The main shaft 2 of this motor is provided with winch spool 4, and winch spool is provided with twisted rope 3, and an end of twisted rope connects pump rod 9, and the other end connects balancing weight 6, directly drives winch spool 4 by the main shaft 2 of motor and works.The 7th, frame.The 8th, the guide rail that the balancing weight lifting is used.14 is winding coil.
Two identical flat permanent magnetic card motors split in both sides as shown in Figure 1, 2, constitute the card formula magneto of twin symmetrical structure.Driver element is placed in the top of pumping unit shelf 7, and there is a winch spool 4 centre, and connection twisted rope 3 one ends on the winch spool 4 are connected with the balancing weight 6 of oil pumper, and the other end is connected with oil well pump (bar) in the oil well.
Driver element shown in Figure 3 is by the rotor 10 of motor, stator 12, and winch spool 4, support 5 and main shaft 2 are formed bilateral symmetry.In the middle of winch spool 4 was placed in, stator 12 was fixed on the support 5.Two blocks of rotors 10 of motor are placed in the outside, two ends of main shaft 2 by keyway.
During work, the driver element of motor moves under the setting of frequency-converting control device, the stator of two symmetries, and rotor is force action simultaneously.When the stator coil of permanent magnet disc motor passes to the alternating current of certain frequency, produce a rotating excitation field at motor gas-gap, p-m rotor rotates under the effect of air-gap field, makes crankmotion thereby drive winch spool 4.Be connected twisted rope (wirerope) on the winch spool and promote the oil well pump and the counterweight of oil pumper, make oil pumper work.
Fig. 4,5 permanent magnet disc motor sketch show: the rotor 10 of permanent magnet disc motor and stator 12 are equal disc face shape, and the teeth groove of its stator armature evenly distributes along the card circumference, perpendicular to the axle center.Stator slot is wide cross section, guarantees rule effect unanimity.The stator tooth cross-section overall shape is fan-like pattern.Its permanent magnetic steel also is the covering of the fan shape, is uniformly distributed along the circumference in card, and magnetic pole circumferentially is spaced along corresponding armature winding position.14 is the winding coil on the stator.
Armature winding is the annular overall structure.Be arc section when the stator armature size is very big to also being divided into, the split manufacturing, each segmentation aggregate erection on disc face becomes whole then.
The control device of card (formula) magneto uses frequency control, can regulate speed, the direction of oil pumper arbitrarily and exerts oneself, and satisfies oil pumper operate as normal requirement in the best condition fully.
