CZPT fluid
Before commencing venture plHangZhou, please refer to our information 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 with regards to the decision of hydraulic fluid and application circumstances. The plug-in motor A2FE is not suited for procedure with HFA hydraulic fluid. If HFB, HFC or HFD or environmentally suitable hydraulic fluids are utilised, the limitations relating to complex info or other seals have to be observed.
Information regarding the selection of hydraulic fluid
The right choice 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 chosen so that the working viscosity in the working temperature range is in the ideal range (νopt), see shaded area of the selection diagram. We recommended that the increased viscosity course be chosen in every single situation. Example: At an ambient temperature of X °C, an running temperature of sixty °C is set in the circuit. In the optimum working viscosity selection (νopt., shaded region) this corresponds to the viscosity classes VG 46 or VG sixty eight to be picked: VG 68.
Note: The situation drain temperature, which is influenced by stress and velocity, can be higher than the circuit temperature or reservoir temperature. At no level of the ingredient may the temperature be larger than one hundred fifteen °C. The temperature variation specified below is to be taken into account when determining the viscosity in the bearing. If the above problems are not able to be maintained thanks to intense running parameters, we advocate the use of a flushing and boost stress valve.
Shaft seal
Permissible stress loading the services lifestyle of the shaft seal is influenced by the velocity of the axial piston unit and the circumstance drain pressure (situation pressure). The mean differential force of 2 bar amongst the case and the ambient strain may possibly not be enduringly exceeded at typical running temperature. For a greater differential strain at reduced speed, 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.
