CZPT fluid
Prior to starting project plHangCZPT, you should refer to our info sheets RE 95710 (mineral oil), RE 95711 (environmentally appropriate hydraulic fluids) and RE 95712 (HFD hydraulic fluids) and RE 95713 (HFA, HFB, HFC hydraulic fluids) for comprehensive information relating to the selection of hydraulic fluid and software circumstances. The plug-in motor A2FE is not appropriate for procedure with HFA hydraulic fluid. If HFB, HFC or HFD or environmentally suitable hydraulic fluids are employed, the limitations relating to technical data or other seals must be noticed.
Particulars relating to the choice of hydraulic fluid
The proper option of hydraulic fluid demands knowledge 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 need to be decided on so that the working viscosity in the running temperature selection is inside the ideal selection (νopt), see shaded area of the variety diagram. We recommended that the increased viscosity course be chosen in every single situation. Example: At an ambient temperature of X °C, an functioning temperature of sixty °C is set in the circuit. In the optimum running viscosity assortment (νopt., shaded region) this corresponds to the viscosity lessons VG 46 or VG sixty eight to be picked: VG 68.
Be aware: The scenario drain temperature, which is affected by force and velocity, can be higher than the circuit temperature or reservoir temperature. At no position of the element might the temperature be larger than one hundred fifteen °C. The temperature variation specified underneath is to be taken into account when deciding the viscosity in the bearing. If the above conditions cannot be taken care of owing to severe operating parameters, we advocate the use of a flushing and boost stress valve.
Shaft seal
Permissible force loading the service daily life of the shaft seal is affected by the speed of the axial piston device and the case drain strain (scenario strain). The suggest differential pressure of two bar in between the scenario and the ambient force could not be enduringly exceeded at normal running temperature. For a greater differential force at decreased pace, see diagram. Momentary stress 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.
