Abstract: A closed loop pneumatic pumping system is provided. The system uses a gas compressor and a high pressure gas tank to exert pneumatic pressure against a reciprocating piston over a wellbore. The piston is connected to a rod string and downhole pump for pumping formation fluids from a wellbore. The system includes an electronic controller that controls movement, including pump speed of the piston as it cycles between upstrokes and downstrokes within a cylinder over the wellbore. In one aspect, speed is controlled by adjusting a speed of the compressor. In another aspect, speed is controlled by adjusting the position of an upstroke control valve and a downstroke control valve. In one aspect, the pump stroke controller is configured to adjust a speed of the upstroke and a speed of the downstroke in response to signals indicative of pump fillage. A method for optimizing pneumatic pumping speed at a wellbore is also provided herein.

Abstract: A high pressure pump including a linear actuator comprising a servo motor to axially rotate a hollow rotor shaft in alternating directions, the servo motor having a stator positioned co-axially around the hollow rotor shaft with an interior of the rotor shaft being co-axially coupled to a drive member to convert axial rotation into reciprocal displacement, the drive member being constrained against linear movement and supporting a shaft. At least one piston is coupled to the shaft and the piston is arranged within a cylinder to define a pumping chamber, whereby alternating rotation of the rotor shaft causes reciprocal linear displacement of the piston to pressurize fluid in the pumping chamber. A drive mechanism includes a controller coupled to a servomotor and an encoder to measure movement of the hollow rotor or output shaft and send a feedback signal proportional to the movement to the controller.

Abstract: A method for increasing compressed air efficiency in a pump utilizes an air efficiency device in order to optimize the amount of a compressed air in a pump. The air efficiency device may allow for controlling the operation of the air operated diaphragm pump by reducing the flow of compressed air supplied to the pump as the pump moves between first and second diaphragm positions. A sensor may be used to monitor velocity of the diaphragm assemblies. In turn, full position feedback is possible so that the pump self adjusts to determine the optimum, or close to optimum, turndown point of the diaphragm assemblies. As such, air savings is achieved by minimizing the amount of required compressed air.

Abstract: A magnetic drive metering pump in which a movable thrust member is fixed to a diaphragm and is axially movable in a magnet shroud. The thrust member, on electrically actuating the magnet shroud, is drawn into the magnet shroud against the force of a recuperating spring, and after deactivating the magnet shroud, is returned to a starting position. The diaphragm cooperates alternately with an outlet and an inlet valve to produce a pump stroke in a pump metering head. The magnetic drive metering pump has a reference element associated with the thrust member and diaphragm, the position of which reference element is detected by a positional sensor. The positional sensor provides a signal which has a fixed relationship to the position of the reference element, and the motion of the thrust member is controlled by a control circuit such that it follows a predetermined nominal profile.

Abstract: A hydraulic system for a reciprocating piston pump that includes an accumulator for producing a steady-pressure supply of compressible material to a distribution nozzle. The hydraulic system includes an adjustable means for constricting the flow of hydraulic fluid from the accumulator to the hydraulic system. The means for constricting the flow of hydraulic fluid allows the operator to compensate for the type of material being pumped, the vertical distance the material is being pumped, as well as the overall distance the material is being pumped in order to reduce or eliminate line surge. The means for restricting the flow from the accumulator preferably includes a needle valve that allows the operator to select the flow characteristic from the accumulator.

Abstract: An apparatus for detecting shaking of stroke of a linear compressor and a method are provided. A linear compressor mis-operates due to change in an external voltage or noise because the shaking of the stroke is detected by the amounts of change in the stroke or current. In order to solve the above problem, a control apparatus of a compressor includes a stroke/current phase difference calculator for calculating the phase differences of the stroke and current using the stroke and the current, which are determined by the increase and the reduction of the stroke due to the voltage generated by a linear compressor, a phase difference change amount calculator for calculating phase difference change amounts using the calculated phase differences of the stroke and the current, a shaking detector for comparing the calculated phase difference change amounts with a reference value for determining whether the shaking of the stroke is detected, to thus determine the shaking of the stroke, and a stroke controller for receiving a stroke shaking detection signal from the stroke shaking detector and changing the stroke voltage according to the magnitude of the request of cooling capacity, which is determined by the change in load, to thus control the driving of the linear compressor, during the operation of the linear compressor.
