7 Periodic maintenance / 7.2 Cleaning the compressor during operation
7.2.3 Prerequisites for wet cleaning of compressor
¡
Engine load of 50 ... 85%
CAUTION
Volume of water
Uncontrolled volumes of water can damage the pressure stages and the en-
gine.
Never connect injection tubes directly to a water pipe or a larger meter-
u
ing container other than that specified by Turbo Systems.
CAUTION
Corrosion and deposits when cleaning
Salt water and cooling water treatment substances damage and adversely
affect parts of the low-pressure and high-pressure stage.
Never use salt water, but only pure water for cleaning.
u
7.2.4 Wet cleaning of compressor
Wet cleaning operations for compressor with direct water supply
Trigger water injection according to the instructions of the enginebuilder.
u
The water pressure before the connection to the pressure stage must be observed (see
u
table Cleaning parameters).
After cleaning operations, a waiting period of at least five minutes is required for the
u
pressure stage to dry.
The cleaning process can be repeated up to three times.
The success of the cleaning can be recognised based on the charging pressure or the ex-
haust gas temperature.
If the cleaning is still unsuccessful after three processes and the engine values are unsatis-
factory, it is recommended to have the low-pressure and / or high-pressure stage checked
and cleaned by a service station.
