Determining the operating characteristics

Flow qv=(Vg×n×ηv)/1000 [l/min]
Torque T=(Vg×Δp)/(20×π×ηhm) [Nm]
Power P=(2π×T×n)/60000=(qv×Δp)/(600×ηt) [kW]

Key

Vg=Displacement per revolution [cm3]

Δp=Differential pressure [bar]

n=Speed [rpm]

ηv=Volumetric efficiency

ηhm=Hydraulic-mechanical efficiency

ηt=Total efficiency ( ηt=ηv × ηhm)

Note

▶Theoretical values, without efficiency and tolerances;values rounded.

▶Operation above the maximum values or below the minimum values may result in a loss of function,a reduced service life or in the destruction of the axial piston unit. Other permissible limit values, such as speed variation, reduced angular acceleration as a function of the frequency and the permissible angular acceleration at start (lower than the maximum angular acceleration) can be found in data sheet 90261.

1) The values are applicable:

- for the optimum viscosity range from νopt = 36 bis 16 mm2/s

- for hydraulic fluids based on mineral oils.

2) The values apply at absolute pabs =1 bar at suction port S

3) Maximum speed (speed limit) with increased inlet pressure pabs at suction port S (see diagram).

to continuous operation.

▶The permissible axial force in direction -Fax  is to be avoided as the lifetime of the bearing is reduced.

▶Radial forces are not permissible.
