Abstract: A fuel supply device includes: a linear actuator; a reciprocating pump having a boosting piston driven by the linear actuator and configured to reciprocate in an axial direction, the reciprocating pump being configured to suck the fuel when the boosting piston moves in a first direction and configured to boost and eject the fuel when the boosting piston moves in a second direction; and a controller configured to control driving of the linear actuator so as to adjust an amount of the fuel ejected from a boosting cylinder per reciprocating time by adjusting a ratio of a fuel ejection time and a fuel suction time of the reciprocating pump without changing the reciprocating time of the boosting piston in accordance with a load of the internal combustion engine. The adjustment adjusts a stroke length of the boosting piston and a moving speed of the boosting piston in the second direction.

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: A simplified system and method for remotely monitoring and optionally further controlling pumpjack operating parameters of a pumpjack located at a distant site but within wireless cell phone station reception. Sensors situated on a pumpjack monitor and create analog output of operational conditions of the pumpjack. Digitizing means digitize the analog output of the sensors to digital data, and modem means transmit the digital data via a wireless cellular network to a network server. A user's computer communicates with the network server via the internet, and accesses the digital data to obtain information regarding the operational conditions of the pumpjack.

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.
