The integration of hydraulic pumps with electronic controls represents the forefront of fluid power technology, leading to significant gains in precision and energy savings. In traditional systems, the pump's output was primarily controlled by hydraulic pilot pressures. In modern electro-hydraulic systems, the pump is equipped with solenoids, typically proportional valves, that receive an electronic signal from a machine's central controller. This allows for infinitely variable control over the pump's displacement. For example, in a plastic injection molding machine, the controller can command the pump to deliver a specific high flow rate during the fast mold closing phase, then instantly switch to a very low flow at high pressure for the packing and holding phases, all while the electric motor runs at a constant, efficient speed. This eliminates the energy losses associated with flow control valves and throttling. These "smart" pumps can also be programmed with complex performance maps and can communicate via CAN bus or other industrial networks, providing a seamless and highly efficient integration into the overall machine control architecture.
