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.

Abstract: A method of operating liquid chromatography apparatus. The method includes the steps of determining a given rate of liquid flow desired from a piston pump to the column; establishing for the piston a predetermined stroke length and rate of reciprocation for providing the given rate of liquid flow; determining for each cycle of the pump a desired liquid volume that would be delivered to the column by the pump if producing the given rate of liquid flow; ascertaining for each cycle of the pump the actual liquid volume delivered thereby to the column; determining for a predetermined operating period of the pump the total desired liquid volume that would have been delivered to the column by the pump if producing the given rate of liquid flow during each cycle of the predetermined operating period; and determining the total actual liquid volume delivered to said column by said pump during all cycles of said predetermined operating period. After comparing the total desired liquid volume with the total actual liquid volume one or more subsequent piston cycles are produced that provide a compensating liquid flow rate different than the given rate of liquid flow in response to a determination during the comparing step that a difference exists between the total actual liquid volume and the total desired liquid volume. The compensating rates of liquid flow correct pumping cycle errors that produce incorrect liquid volume flow.
