CZPT fluid
Just before starting up project plHangCZPT, remember to refer to our data 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 comprehensive info relating to the decision of hydraulic fluid and software situations. The plug-in motor A2FE is not suited for operation with HFA hydraulic fluid. If HFB, HFC or HFD or environmentally satisfactory hydraulic fluids are employed, the restrictions regarding specialized information or other seals should be observed.
Particulars concerning the option of hydraulic fluid
The appropriate decision of hydraulic fluid demands knowledge of the working temperature in relation to the ambient temperature: in a closed circuit, the circuit temperature, in an open circuit, the reservoir temperature. The hydraulic fluid should be decided on so that the running viscosity in the functioning temperature selection is in the optimum selection (νopt), see shaded region of the choice diagram. We advised that the larger viscosity class be selected in each case. Instance: At an ambient temperature of X °C, an operating temperature of sixty °C is established in the circuit. In the optimum running viscosity variety (νopt., shaded spot) this corresponds to the viscosity courses VG forty six or VG sixty eight to be chosen: VG 68.
Observe: The scenario drain temperature, which is influenced by pressure and speed, can be larger than the circuit temperature or reservoir temperature. At no point of the component might the temperature be larger than 115 °C. The temperature variation specified below is to be taken into account when deciding the viscosity in the bearing. If the above problems can not be maintained owing to severe functioning parameters, we recommend the use of a flushing and increase force valve.
Shaft seal
Permissible stress loading the support existence of the shaft seal is influenced by the velocity of the axial piston unit and the situation drain force (circumstance strain). The suggest differential strain of 2 bar amongst the circumstance and the ambient strain may possibly not be enduringly exceeded at normal working temperature. For a larger differential strain at reduced 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.
