CZPT fluid
Just before beginning task plHangCZPT, please refer to our knowledge sheets RE 95710 (mineral oil), RE 95711 (environmentally suitable hydraulic fluids) and RE 95712 (HFD hydraulic fluids) and RE 95713 (HFA, HFB, HFC hydraulic fluids) for detailed info concerning the option of hydraulic fluid and application conditions. The plug-in motor A2FE is not suited for procedure with HFA hydraulic fluid. If HFB, HFC or HFD or environmentally acceptable hydraulic fluids are utilized, the restrictions relating to complex info or other seals need to be noticed.
Information concerning the option of hydraulic fluid
The appropriate option of hydraulic fluid calls for information of the functioning temperature in relation to the ambient temperature: in a shut circuit, the circuit temperature, in an open up circuit, the reservoir temperature. The hydraulic fluid need to be chosen so that the working viscosity in the functioning temperature assortment is inside the ideal range (νopt), see shaded area of the selection diagram. We advised that the larger viscosity course be picked in each and every case. Illustration: At an ambient temperature of X °C, an functioning temperature of sixty °C is established in the circuit. In the optimum operating viscosity selection (νopt., shaded location) this corresponds to the viscosity courses VG 46 or VG 68 to be chosen: VG sixty eight.
Note: The situation drain temperature, which is impacted by strain and pace, can be higher than the circuit temperature or reservoir temperature. At no stage of the ingredient could the temperature be higher than a hundred and fifteen °C. The temperature big difference specified beneath is to be taken into account when figuring out the viscosity in the bearing. If the over circumstances are not able to be preserved because of to severe working parameters, we recommend the use of a flushing and increase strain valve.
Shaft seal
Permissible stress loading the services lifestyle of the shaft seal is affected by the pace of the axial piston unit and the circumstance drain force (scenario stress). The indicate differential pressure of two bar between the case and the ambient strain may possibly not be enduringly exceeded at regular functioning temperature. For a increased differential force 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.
