摘要： A well pump control system is disclosed for utilization with a conventional well pump having a stationary member and a reciprocating member. The reciprocating member operates a down-hole pump and is attached to a rocking beam through a load cell. The rocking beam is driven by an electric motor through a counterbalanced crank. The strain present on the reciprocating member as detected by the load cell is utilized to operate a variable frequency drive unit which acts to control the frequency of the voltage applied to the electric motor. In this manner, the speed of the motor may be selectively and gradually varied during the pump cycle to both minimize power consumption and increase slip during heavy loading. Additionally, the maximum amount of strain present on the reciprocating member can be controlled throughout the entire cycle to minimize maintenance costs associated with excessive strain.

摘要： A well pump control system is disclosed for utilization with a conventional well pump having a stationary member and a reciprocating member. The reciprocating member operates a down-hole pump and is attached to a rocking beam. The rocking beam is driven by an electric motor through a counterbalanced crank. The position of the counterbalanced crank and the speed of the electric motor are utilized to operate a reduced voltage starter which acts to control the voltage applied to the electric motor. In this manner, voltage may be selectively and gradually applied to and removed from the electric motor at selected points during the pump cycle to both minimize power consumption and increase slip during heavy loading, by allowing the momentum of the crank to operate the reciprocating member during at least a portion of each cycle of the pump.

摘要： A processing system for delinting cotton has a delinter driven by an AC drive motor. The delinter is fed by a feeder/cleaner driven by a DC feed motor. A visual display ammeter measures the current drawn by the drive motor and produces a given load voltage corresponding to the measured current. The load voltage is then translated into a feed voltage to the feed motor, thereby regulating the feed into the delinter at a predetermined rate responsive to the load on the drive motor.
