The A2FE set plug-in motor with axial tapered piston rotary team of bent-axis design and style, for hydrostatic drives in open up and shut circuits
-Much-achieving integration in mechanical gearbox owing to recessed mounting flange positioned in the heart of the case (very space-preserving construction)
-The output pace is dependent on the circulation of the pump and the displacement of the motor.
-The output torque boosts with the force differential between the large-pressure and the minimal-strain side.
-Small dimensions.
-Large complete effectiveness.
-CZPT unit, ready-assembled and tested.
-Easy to put in, simply plug into the mechanical gearbox.
-No configuration technical specs to be noticed when setting up.

CZPT fluid
Ahead of starting up project 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 thorough data with regards to the option of hydraulic fluid and application circumstances. The plug-in motor A2FE is not appropriate for procedure with HFA hydraulic fluid. If HFB, HFC or HFD or environmentally appropriate hydraulic fluids are utilised, the constraints with regards to complex information or other seals must be observed.
Specifics concerning the option of hydraulic fluid
The proper selection of hydraulic fluid demands knowledge 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 decided on so that the running viscosity in the working temperature assortment is inside of the optimum range (νopt), see shaded location of the choice diagram. We recommended that the larger viscosity course be picked in every situation. Case in point: At an ambient temperature of X °C, an running temperature of sixty °C is set in the circuit. In the the best possible functioning viscosity variety (νopt., shaded area) this corresponds to the viscosity classes VG forty six or VG 68 to be chosen: VG sixty eight.
Notice: The scenario drain temperature, which is affected by force and pace, can be larger than the circuit temperature or reservoir temperature. At no stage of the part may the temperature be higher than one hundred fifteen °C. The temperature distinction specified beneath is to be taken into account when identifying the viscosity in the bearing. If the above circumstances are not able to be managed because of to intense working parameters, we recommend the use of a flushing and increase force valve.
Shaft seal
Permissible stress loading the services life of the shaft seal is influenced by the speed of the axial piston unit and the scenario drain stress (scenario stress). The indicate differential pressure of two bar in between the situation and the ambient stress might not be enduringly exceeded at regular functioning temperature. For a larger differential pressure at decreased velocity, 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.
