PUMPING UNIT FOR OIL PRODUCTION Russian patent published in 2022 - IPC F04B47/02 

FIELD: oil production.

SUBSTANCE: invention relates to the technology of mechanized oil production, in particular to the design of technical means that ensure the implementation of this technology. The pumping unit for oil production includes a balancing beam 4, mounted by means of a hinge 5 on a support column and equipped with heads 6 at both ends, providing the possibility of servicing two sucker rod pumps, and connected with a drive containing an electric motor. The electric motor performs the function of a mechanism 10 for converting rotational motion into oscillatory, for which its stator 8 is made arc-shaped and connected to the support column. The rotor 9 is a permanent magnet 11 fixed on the beam 4. The center of the radius of curvature of the inner surface of the stator 8 is located on the geometric axis of the hinge 5. The magnet 11 is mounted on the rod 12 above the hinge 5 perpendicular to the beam 4.

EFFECT: invention is aimed at simplifying the design of the pumping unit drive, reducing the metal consumption of the equipment.
