RE 92 711/03.00DR Pressure ControlThe pressure controller serves to maintain a constant pressure in ahydraulic system within the control range of the pump. The pumptherefore supplies only the amount of hydraulic fluid required by thesystem. Pressure may be steplessly set at the control valve.BStatic operating curve(at n 1= 1500 rpm; t oil= 50° C)hysteresis and pressure rise ∆pq v maxflow q vq v minadjustment range20 280operating pressure p [bar]Dynamic operating curvesThe operating curves are mean values measured under test conditionswith the unit mounted inside the tank.Conditions: n = 1500 rpmt oil= 50° CMain relief set at 350 barLoad steps were obtained by suddenly opening and closing thepressure line with a pressure relief valve as load valve 1 m from theoutput flange of the pump.S L1 LPortsB Pressure portS Suction portL, L1 Case drain ports ( L1 plugged)350operating pressure p [bar] ➝displacement ➝(swivel angle)300250200150100500VgmaxVgmincontrol time tController dataHysteresis and repetitive accuracy ∆p __________ max. 3 barMax.
