Abstract
An energy efficient high pressure pump system includes a drive motor driving an eccentric transmission, which drives a reciprocation pump having a number of cylinders. The eccentric transmission transmits a torque demand from the reciprocating pump, which varies with time, to the drive motor such that the torque demand on the drive motor is substantially constant. The pump system includes an eccentric sprocket mounted on the output shaft of a drive motor and driving an eccentric sprocket on an idler which includes a concentric sprocket driving a concentric sprocket on the reciprocating pump with the eccentricity of the eccentric sprockets being proportional to the maximum and minimum torque demand characteristics of the reciprocating pump.
