Cleaning method
Cleaning of the compressor during operation is carried out using the
cleaning method described in the following:
¡
Wet cleaning
This cleaning method has been tested and approved by ABB Turbo Sys-
tems.
To clean the compressor stage during operation, water is injected in
front of the compressor wheel through an injection pipe fitted in the fil-
ter silencer.
The water does not act as a solvent, but the contamination deposit is re-
moved by the mechanical impact of the droplets. This is a very suitable
process, provided that the degree of contamination is not too high.
CAUTION
Corrosion and deposits when cleaning
Damage and impairment of turbocharger parts due to salt water and
cooling water additives
Don't use salt water for cleaning, but only clean fresh water.
u
If several turbochargers are installed on one engine, we recommend
cleaning the turbocharger compressors one after the other.
