Data
Rated speed
1)
Rated speed is the highest allowed speed
for a char ge pressure of 12 bar (175 psi)
above case pressure. When a closed loop
system is used, a minimum of 15% of oil is
to be exchanged in the main loop.
Max speed
Maximum speed is the maximum allowed
speed. Special considerations are nece-
ssary regarding charge pressure, cooling
and choice of hydraulic system for speeds
rated above.
Accepted conditions for stan dard type
of mo tor:
1. Oil viscosity 20 - 40 - 10000 cSt
(98 - 187 - 4650 SSU). See page 21.
2. Temperature -35°C to +70°C
(-31°F to +158°F).
3. Running case pressure 0-3 bar (0-45 psi)
Max case pressure 8 bar (116 psi)
4. Charge pressure (see diagram).
5. Volumetric losses (see diagram).
Defi nitions
1)
Operating above rated conditions requires
Hägglunds approval.
*Related to a required charge pressure of 12 bar/175 psi for motors in
braking mode. (Spe ci al considerations regarding charge pressure, cooling
and choice of hy drau lic system for speeds above rated, 4 ports must be
used for higher speed).
**The motors are designed according to DNV-rules. Test pressure 420
bar/6000 psi. Peak/transient pressure 420 bar/6000 psi maximum, allowed
to occur 10000 times.
***Speed above 280 rpm requires viton seals. Max permitted continues
case pressure is 2 bar.
