    Abstract: A method and system for pumping unit with an elastic rod system is applied to maximize fluid production. The maximum stroke of the pump and the shortest cycle time are calculated based on all static and dynamic properties of downhole and surface components without a limitation to angular speed of the prime mover. Limitations of structural and fatigue strength are incorporated into the optimization calculation to ensure safe operation while maximizing pumped volume and minimizing energy consumption. Calculated optimal prime mover speed is applied to the sucker rod pump by means of beam pumping, long stroke or hydraulic pumping unit by controlling velocity, acceleration and torque of the electric prime mover or by controlling pressure and flow rate in hydraulically actuated sucker rod pumping system.

    Abstract: Rotational force from a driving device 11 is transmitted to an eccentric cam 32 through a rotating rod 31, and the eccentric cam 32 causes a piston 22 and a piston rod 25 to move up and down in a reciprocating manner by its rotation. Atmospheric air is inspired into a first chamber R1 in a cylinder 21 upon the descent of the piston 22. Upon the rise of the piston 22, the air in the first chamber R1 is compressed, and the compressed high-pressure air is discharged to an accumulator 12 through a discharge valve 25. The accumulator communicates with a second chamber R2 in the cylinder 21. When the air pressure in the accumulator 12 increases, this high-pressure air pushes the piston 22 to cancel the contact between the piston rod 26 and the eccentric cam 32, whereby the power transmission from a power transmission device 30 to a pressure conversion mechanism 20 is cut off.
