Just before commencing venture plHangZhou, make sure you refer to our info sheets RE 95710 (mineral oil), RE 95711 (environmentally acceptable hydraulic fluids) and RE 95712 (HFD hydraulic fluids) and RE 95713 (HFA, HFB, HFC hydraulic fluids) for comprehensive details regarding the decision of hydraulic fluid and software situations. The plug-in motor A2FE is not appropriate for operation with HFA hydraulic fluid. If HFB, HFC or HFD or environmentally suitable hydraulic fluids are used, the constraints regarding technological information or other seals must be noticed.
Particulars concerning the option of hydraulic fluid
The proper decision of hydraulic fluid needs understanding of the operating temperature in relation to the ambient temperature: in a shut circuit, the circuit temperature, in an open circuit, the reservoir temperature. The hydraulic fluid ought to be selected so that the running viscosity in the operating temperature assortment is inside the the best possible variety (νopt), see shaded area of the selection diagram. We suggested that the larger viscosity course be chosen in each and every case. Instance: At an ambient temperature of X °C, an running temperature of sixty °C is established in the circuit. In the optimum functioning viscosity assortment (νopt., shaded spot) this corresponds to the viscosity classes VG 46 or VG sixty eight to be chosen: VG 68.
Note: The circumstance drain temperature, which is impacted by strain and speed, can be larger than the circuit temperature or reservoir temperature. At no stage of the part could the temperature be increased than 115 °C. The temperature variation specified underneath is to be taken into account when determining the viscosity in the bearing. If the above problems are not able to be preserved owing to intense working parameters, we advocate the use of a flushing and improve strain valve.
Permissible strain loading the services lifestyle of the shaft seal is influenced by the pace of the axial piston device and the scenario drain stress (circumstance stress). The mean differential stress of 2 bar in between the case and the ambient strain might not be enduringly exceeded at normal working temperature. For a higher differential strain at lowered velocity, see diagram. Momentary force spikes (t < 0.1 s) of up to 10 bar are permitted. The service life of the shaft seal decreases with an increase in the frequency of pressure spikes.
