Cleaning the compressor during operation
5.3
These instructions for wet cleaning only apply when cleaning is carried out
with clean water and under the precondition that the enginebuilder ap-
proves the process.
The contamination of the compressor stage (compressor wheel, wall in-
sert and diffuser) depends on the degree of purity of the taken-in air.
Deposits can form in the flow channels if salt, oil mist, exhaust gas or dust
are sucked in with the air.
Consequences of contamination:
Impaired compressor efficiency
Higher exhaust gas temperatures
Increased fuel consumption
Increased rotor unbalance
Periodic cleaning of the compressor during operation prevents or delays
any major increase in contamination. But it never replaces the regular
service work where the turbocharger is completely dismantled and the
compressor is mechanically cleaned.
The interval between periodic cleaning is very dependent on the operating
conditions. In general, cleaning should be carried out every 25 ... 100 op-
erating hours.
Should the specified cleaning intervals prove incompatible with engine
operation, please contact ABB Turbo Systems.
