Open circuit Axial piston variable pump , A4VSO180DR/10R-PPB13N00
Hydraulic adjustment LR2N and LR3N pilot-pressure dependent, basic setting Vg min
(for further information, see data sheet 92064)
With superimposed power control.
The displacement volume is adjusted proportionally to the pilot pressure in PSt.
The additional hyperbola power controller is superimposed on the pilot pressure signal and keeps the specified drive output constant.
Optional:
▶▶ Power characteristics, remotely controllable (LR3N)
▶▶ Pressure control (LR.DN),
▶▶ Remote pressure control (LR.GN)
▶▶ Electrical control of pilot pressure (LR, NT)
Filtration of the hydraulic fluid
Finer filtration improves the cleanliness level of the hydraulic fluid, which increases the service life of the axial piston unit.
A cleanliness level of at least 20/18/15 is to be maintained according to ISO 4406.
At a hydraulic fluid viscosity of less than 10 mm2/s (e.g. due to high temperatures during short-time duty) at the drain port, a cleanliness level of at least 19/17/14 according to ISO 4406 is required.
For example, the viscosity corresponds to 10 mm2/s:
–– HLP 32 a temperature of 73 °C
–– HLP 46 a temperature of 85 °C
