Pressure valves are an important component in hydraulics and enable the system pressure in a plant to be influenced. These keep the output pressure constant despite variable input pressure. However, servo motor pump units are also suitable for pressure control via the variable speed and the associated variable volume flow. There, the pump controls the speed via the motor and the inverter to determine the delivery volume and the pressure.
How does pressure control with a servo motor pump unit work and what advantages does this have, for example, for press brakes and injection molding machines? Key Market Manager Ahmed and Applicaton Engineer Bernhard talk about this in Episode 3 of the HAWE Tech Podcast.
