Cleaning the compressor during
operation
Cleaning the compressor during operation
The degree of contamination of the compressor stage (compressor wheel
and diffuser) depends on how clean the drawn-in air is.
Deposits of dirt can build up in the flow channels if the following
substances are in the intake air:
Oily or salty mist
Solid combustion residues
Various kinds of dust
Contamination of the compressor stage has a negative influence on the
compressor efficiency and the charging pressure.
This results in higher exhaust gas temperatures and higher fuel
consumption by the engine. Contamination of 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.
If the coating of dirt is very thick and hard, the compressor can only be
cleaned manually when disassembled. This cleaning must be carried
out by an ABB Turbocharging Service Station.
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.
