Cleaning the compressor during operation

These instructions for wet cleaning apply only when cleaning is carried
out with clean water and the engine manufacturer permits the process.
How dirty the compressor stage (compressor wheel and diffuser)
becomes, depends on how clean the drawn-in air is.
Deposits of dirt can build up in the flow ducts if the following substances
are in the intake air:
 Oily or salty mist
 Solid combustion residues
 Various kinds of dust
Dirty deposits on the compressor stage have a negative influence on the
compressor efficiency and the charging pressure.
This results in higher exhaust temperatures and higher fuel consumption
by the engine. Dirty deposits on the compressor can also increase rotor
unbalance.
Under no circumstances is periodic cleaning of the compressor during
operation a substitute for the service work carried out when the
turbocharger is completely dismantled and the compressor is cleaned
mechanically.
The interval between periodic cleaning is very dependent on the operating
conditions. In general, cleaning should be carried out every 25 to 100
operating hours.
Cleaning intervals
Should the specified cleaning intervals prove incompatible with engine
operation, please contact ABB Turbo Systems.
