    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 magnetic drive metering pump in which a movable thrust member fixed to a connecting rod is axially movable in a longitudinal axis in a magnet shroud anchored in a pump housing so that the thrust member with the connecting rod, on electrically driving (actuating) the magnetizing coil, is drawn into the magnet shroud against the force of a recuperating spring, reducing an air gap between the thrust member and an inner face of magnetic shroud, into a bore in the magnet shroud and after deactivating the magnet the thrust member is returned to the starting position by the recuperating spring so that the thrust member and an elastic displacement member actuated thereby on carries out an oscillating motion continued activation and deactivation of the magnetizing coil, which diaphragm cooperates alternately with an outlet and an inlet valve to produce a pump stroke (pressure stroke) and a priming stroke in a metering head arranged in the longitudinal axis. In such a magnetic drive metering pump, a reference element is associated with the module constituted by the thrust member and connecting rod, the position of which reference element is detected by a positional sensor, wherein the positional sensor provides an actual signal which is in a fixed relationship to the position of the reference element, and in that the motion of the unit formed by the thrust member and the connecting rod is influenced as regards control accuracy via a control circuit so that it follows a predetermined nominal profile.

    Abstract: A viscous material (sludge) pump, a method of accurately estimating output of such a pump and a method of efficiently managing such a pump. The pump can be the single or double cylinder variety. The pump is calibrated to determine a calibrated sludge-weight output of the pump in terms of a parameter defined as a “lost travel” position of the piston in the pump chamber. This position is defined in terms of the position of the piston in the chamber when the pressure in the chamber reaches a preselected reference pressure expressed in terms of a percentage of the maximum pressure reached in the chamber during a just previous discharge stroke of the piston. The lost travel parameter is used for comparison purposes to accurately estimate actual pump output based on the calibrated pump output at the calibrated value of the lost travel parameter. The pump is managed efficiently by management of the speed of the feed auger. This assures that an approximately optimal amount of material is loaded into the pumping chamber each pumping cycle. The pump is also managed by management of the pump stroke distance and speed.

    Abstract: A linear compressor driving apparatus having an inverter which supplies a driving current of a predetermined frequency to a linear compressor. The linear compressor driving apparatus further includes an inverter controller for controlling the inverter on the basis of resonance frequency information so that the frequency of an output current from the inverter becomes equal to the resonance frequency, and instantaneous values of an output current and an output voltage from the inverter are measured at a phase timing in which an amount of change in the output current of the inverter becomes zero. A piston stroke is calculated from these measured values. In such a linear compressor driving apparatus, a stroke and a top clearance of the piston of the linear compressor can be accurately detected by relatively simple arithmetic processing without using a position sensor.

    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.
