METHODS AND SYSTEMS FOR FLOW SHARING IN A HYDRAULIC TRANSFORMER SYSTEM WITH MULTIPLE PUMPS

摘要

To achieve flow demands for high flow services, a hydraulic system shares a flow between a hydraulic transformer and one or more hydraulic pumps. The hydraulic transformer is in selective fluid communication with the pumps and actuates a first load. A second load is driven by an actuator in selective fluid communication with the pumps and the hydraulic transformer. The hydraulic system includes a controller to reduce dynamic responses in the system by causing flow sharing between the hydraulic transformer and a directional flow control valve.
