  • Comparison of pressure control concepts and their use on a hydraulic press brake
    Lovrec, Darko ; Kastrevc, Mitja
    Industrial variable electrohydraulic supply systems can be controlled at the hydraulic or the electric side. Constant speed induction motors in combination with an adjustable pump displacement volume ... or a constant displacement volume pump in combination with a variable rotational speed motor are used in order to control the flow or the pressure. The latter concept is increasingly used due to low energy loss, low noise emission and a convenient price/performance ratio. The hydraulic press brake used for castingproduct matching in the automobile industry is discussed. An exact mathematical model was made for the supply system with a constant displacement volume pump combined with a variable rotational speed motor. The numerically obtained value verified by experimental results prove that such a combination provides the same dynamic behaviour as the combination of a constant speed induction motor with an adjustable pump.
