Can fixed displacement pumps reduce energy consumption in electro-hydraulic systems?
The study employs simulation and testing to demonstrate that this approach leads to the optimal reduction of EHS’s overall power consumption. The researchers also suggest using fixed displacement pumps as an additional measure to further lower energy consumption in electro-hydraulic systems.
Can electrohydraulic systems reduce energy consumption?
One study 11 investigates the use of electro-hydraulic systems and suggests that the energy consumption of EHS can be reduced by concurrently controlling the actuator position and supply pressure. To achieve this, the pressure relief valve’s setting is adjusted according to the spool position of the proportional directional valve.
