Pipe description
Flange connections are as standard according to DIN 2501
Starting System
The engine is started by means of a built-on air
starter, which is a turbine motor with gear box, safety
clutch and drive shaft with pinion. Further, there is a
main starting valve.
Control System
The air starter is activated electrically with a pneu-
matic 3/2 way solenoid valve. The valve can be
activated manually from the starting box on the
engine, and it can be arranged for remote control,
manual or automatic.
For remote activation, the starting spool is con-
nected so that every starting signal to the starting
spool goes through the safe start function, which is
connected to the converter for engine RPM.
General
The compressed air system on the engine contains
a starting system, starting control system and safety
system. Further, the system supplies air to the jet
system.
The compressed air is supplied from the starting air
receivers (30 bar) through a reduction station, where
from compressed air at 7-9 bar is supplied to the
engine.
To avoid dirt particles in the internal system, a
strainer is mounted in the inlet line to the engine.
