A means for monitoring operation of the pump is provided. The means for monitoring includes a means for sensing a first parameter related to operation of the pump drive, a means for sensing a second parameter indicative of operation of the piston, and a means for determining errors in the operation of the pump based upon the first parameter and the second parameter.

    Abstract: The present invention discloses a system for pumping a fluid into a common pressure outlet. The system contains a plurality of reciprocating pumps. A separate sensor coupled to one cylinder of each pump provides an electrical signal each time the piston in that cylinder is at a predetermined position. A speed control circuit is provided to independently adjust the speed of each pump. Manual speed control for each pump is provided through a separate throttle for each pump. A pump control circuit coupled to each of the throttles, sensors and speed control circuit controls the operation of the system. An operator determines which of the pumps to operate by closing appropriate bypass switches provided at the pump control circuit, turns on the first (master) pump and adjusts its associated throttle to operate the pump at a desired speed. The operator then turns on each of the remaining (slave) pumps. The pump control circuit utilizing the information from each of the sensors provides control signals to the speed control circuit, which adjusts the speed of each of the slave pumps to synchronize the speeds of pumps and to maintain a desired phase shift between the sensor signals. The system also displays the speed of each of the operating pumps and the total fluid volume being discharged by all of the operating pumps.

    Abstract: A diaphragm metering pump having control over diaphragm extension is described. A position sensor is incorporated in a diaphragm metering pump to indicate the relative position of the diaphragm during flexure. When excessive extension of the diaphragm is sensed by the position sensor, a control valve will provide hydraulic fluid from a reservoir for inhibiting further deflection of the diaphragm in the direction in which it was moving. Diaphragm life is extended as well as the accuracy of metering provided by the pump maintained.

    Abstract: A variable-speed drive controller and associated methods are disclosed for reciprocated lifting systems, particularly long-stroke, fluid-pumping systems such as certain oil-producing equipment. A variable-speed drive is controlled through an electronic feedback loop by a programmable controller, which varies the speed of the drive when sensors detect the passage of the reciprocating mechanism. The controller can be set to slow the drive when the reciprocating mechanism reaches the end of the stroke, to permit faster production of fluid without increased mechanical wear on the reciprocating mechanism or increased stress on the lifting string. The controller also can be set to slow the drive on the downstroke, such as to permit faster production of fluid when pumping viscous liquid.
