3. Axial Damper Monitor
The engine has a system that monitors the axial damper, installed at the free end
above the end casing (see Fig. 2). This system monitors the oil pressure in the front
and rear spaces of the axial damper.
If the oil pressure decreases below a set value, an alarm is activated (for more data
about the setting values, see 0250−2 Alarms and Safeguards).
The cause of this alarm must be investigated and and the problem corrected. See the
possible causes that follow:
D The orifices in the pressure gauge pipes are clogged.
D The shut-off valves are closed in the pressure gage pipes.
D There is low oil pressure and / or high oil temperature in the bearing oil system.
D The sealing rings have too much wear, e.g. dirt particles (clearance is too large).
D A non-return valve is blocked.
