Patent ID: 10480547

Abstract:
An electro-mechanical actuation system for a piston-driven fluid pump. The electro-mechanical actuation system includes a plurality of electro-mechanical actuators, and a control system electrically connected to the plurality of electro-mechanical actuators. Each electro-mechanical actuator is configured to operatively couple with a piston of the fluid pump. The control system is configured to determine a target output of fluid to be pumped by the fluid pump, individually control a speed and a phase at which each electro-mechanical actuator actuates the piston, such that the plurality of cylinders collectively pump fluid at an actual output that corresponds to the target output, and in response to detecting an operating condition, individually adjust the speed and/or the phase at which one or more of the electro-mechanical actuators actuates the piston based on the operating condition to thereby cause the actual output of the fluid pump to correspond to an updated target output.
