7 Periodic maintenance / 7.2 Cleaning the compressor during operation
7.2.3 Wet cleaning with direct water supply
Prerequisites
Do not clean the compressors of the different high and low-pressure stages at the same
time, but one after the other.
On V-engines with several low-pressure and/or high-pressure stages per engine, Turbo Sys-
tems recommends the parallel cleaning of the LP compressors as well as the parallel clean-
ing of the HP compressors. This cleaning process is faster and reduces the risk of surging of
the low-pressure and high-pressure stages.
Wet cleaning operations for compressor with direct water supply
Trigger water injection according to the instructions of the enginebuilder.
u
Observe water pressure before connection to pressure stage.
u
Operate engine for at least five additional minutes after cleaning.
u
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.
