4.4.3.1 Components of Cooling System (Raw water) 4000s FC
Fig. 4.4.3-1: Raw water intake
Raw water intake
The diagram shows the supply pipes for the generator. The connection neck
for the raw water connection is shown on the right hand side. The cross-sec-
tion of the intake pipe should be nominally larger than the generator connec-
tion.

Raw water impeller pump
The raw water pump is fitted with a rubber impeller. This pump is self-induc-
tive. If, for example, you forget to open the sea valve, then you must expect
the impeller to be destroyed after a short period of time. It is recommended
to store several impellers on board as spare parts.

Ventilation valve
An appropriate ventilation line must be installed, if the danger exists that the
generator can stand only briefly by movements of the ship below the waterli-
nie. For this generally a hose line is prepared at the generator housing. The
two pipe unions are bridged by a hose shaped part, which can be removed.
The raw water flows then through the oil cooler, which is mounted under the
engine.
