Water washing arrangement / tool
Some customized engines are delivered with water
washing arrangement consisting of a pipe system
with a regulating valve, a manoeuvring valve, a 3-
way cock and a drain pipe with a drain valve from
the gas outlet, see illustration on work card
512-15.00/612-15.00.
New engines are as standard delivered with "water
washing gun" as a part of standard tools for
engines. The tool can be seen in figure 2 and is
using the same connecting as the dry cleaning con-
nection.
Figure 2: .
The water for washing the turbine, is supplied from
the external fresh water system through a flexible
hose with couplings. The flexible hose must be dis-
connected after water washing.
By activating the maneuvering valve and the regu-
lating valve the water is sprayed into the exhaust
gas pipe before the turbine side of the turbo-
charger. See specific work card for water washing
of turbine side. The water that is not evaporated is
led out through a drain pipe in the exhaust gas out-
let.
