Syhdfee Syhdfec Syhdfed Syhdfen Sy2dfe Sy3dfe and Closed-loop SYDFE1 SYDFED SYHDFED SYDFEE SYDFEC SYDFEn SY2DFE sy2dfee SY3DFE SYDFE Hydraulic Piston Pump
control system is used for the electro-hydraulic control of swivel angle, pressure and power of an axial piston variable displacement pump.
The control system consists of the following components:
- Axial piston variable displacement pump A10VSO.../32
- VT-DFP.-2X proportional valve as pilot valve including inductive position transducer for valve position detecting. With versions SYDFEE and SYDFEC, the pilot valve contains electronics for system control.
- For SYDFE1: External control electronics VT 5041-3X for performing all electric functions necessary for the SYDFE1-3X.
- Position transducer for detecting the swivel angle
- Pressure transducer with suitable signal level and dynamics.
Details regarding the choice of hydraulic fluid
The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in a closed circuit the circuit temperature. The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range - the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each case. Example: At an ambient temperature of X °C an operating temperature of 60 °C is set. In the optimum operating viscosity range (shaded area) this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68. Please note: The case drain temperature, which is affected by pressure and speed, is always higher than the circuit temperature. At no point in the system may the temperature be higher than 115 °C. If the above conditions cannot be maintained due to extreme operating parameters, please consult us.
