CZPT fluid
Prior to beginning task plHangCZPT, you should refer to our data sheets RE 95710 (mineral oil), RE 95711 (environmentally satisfactory hydraulic fluids) and RE 95712 (HFD hydraulic fluids) and RE 95713 (HFA, HFB, HFC hydraulic fluids) for thorough details regarding the selection of hydraulic fluid and software problems. The plug-in motor A2FE is not suitable for operation with HFA hydraulic fluid. If HFB, HFC or HFD or environmentally suitable hydraulic fluids are utilised, the constraints concerning complex info or other seals have to be observed.
Specifics regarding the decision of hydraulic fluid
The proper choice of hydraulic fluid demands understanding of the running 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 ought to be decided on so that the functioning viscosity in the working temperature assortment is inside the the best possible variety (νopt), see shaded location of the assortment diagram. We advised that the increased viscosity course be chosen in every situation. Example: At an ambient temperature of X °C, an working temperature of sixty °C is established in the circuit. In the optimum running viscosity range (νopt., shaded region) this corresponds to the viscosity lessons VG forty six or VG 68 to be picked: VG sixty eight.
Notice: The situation drain temperature, which is influenced by stress and speed, can be larger than the circuit temperature or reservoir temperature. At no stage of the ingredient might the temperature be higher than one hundred fifteen °C. The temperature difference specified under is to be taken into account when identifying the viscosity in the bearing. If the earlier mentioned situations are not able to be taken care of due to excessive running parameters, we recommend the use of a flushing and enhance pressure valve.
Shaft seal
Permissible stress loading the service daily life of the shaft seal is affected by the pace of the axial piston device and the circumstance drain stress (case pressure). The indicate differential stress of 2 bar amongst the case and the ambient strain might not be enduringly exceeded at regular working temperature. For a larger differential strain at decreased speed, see diagram. Momentary pressure 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.
