Fluid
Prior to project design, please see our data sheets RE 90220 (mineral oil ) and RE 90221 (ecologically acceptable fluids) for detailed information on fluids and application conditions. When using ecologically acceptable fluids attention must be paid to possible limitations of the technical data.
Notes on the selection of hydraulic fluid
In order to select the correct fluid, it is necessary to know the operating temperature in the tank (open circuit) in relation to the ambient temperature. The hydraulic fluid should be selected so that within the operating temperature range, the viscosity lies within the optimum range (νopt.); see shaded section of the selection diagram. We recommend that the higher viscosity grade is selected in each case. Example: at an ambient temperature of X°C the operating temperature in the tank is 60 °C. In the optimum viscosity range νopt (shaded area), this corresponds to viscosity grades VG 46 or VG 68, VG 68 should be selected. important: The leakage oil temperature is influenced by pressure and speed and is typically higher than the tank temperature. However max. temperature at any point in the system may not exceed 115 °C. At high temperatures please use FKM seals.
DG - two point, direct control
The pump can be set to a minimum swivel angle by connecting an external switching pressure to port X. This will supply the control piston directly with control oil; a minimum pressure of 50 bar is required.
DR - Pressure control
The pressure control serves to maintain a constant pressure in the hydraulic system, within the control range of the pump. The pump therefore supplies only the amount of hydraulic fluid required by the actuators. Pressure can be steplessly set at the pilot valve.
DRG - Pressure control, remote
A pressure relief valve may be externally piped to port X for remote control purposes. However it is not included in the scope of supply with the DRG control. The differential pressure at the DRG control spool is set as standard to 20 bar and this results in a pilot flow of 1,5 L/min. If another setting is required, please state this in clear text.
DFR/DFR1-Pressure-flow control
In addition to the pressure control function, the pump flow to the actuator may be varied by means of a differential pressure (eg. over an orifice or directional control valve). The pump supplies only the amount of fluid as required by the actuator. In the DFR1-valve
DFLR - Pressure/flow/power control
In order to achieve a constant drive torque with a varying operating pressure, the swivel angle and with it the output flow from the axial piston unit is varied so that the product of flow and pressure remains constant.
FHD - Displacement control, pilot pressure dependent, with pressure control
The swivel angle of the pump, and hence the displacement or flow, is dependent on the pilot pressure pSt X in port X.
A constant pressure py = 35 bar is required at port Y. An overriding pressure control is integrated, and can be sleeplessly set at the control valve.Technical Data Brueninghaus Hydromatik Rexroth A10VO
