Cleaning the compressor during operation
6.2.1
Introduction
Approval by enginebuilder
The following instructions for wet cleaning only apply to cleaning with pure water and under
the precondition that the enginebuilder approves the process.
General
The contamination of the compressor stage (compressor wheel and diffuser) depends on
the degree of purity of the sucked-in air.
Deposits can form in the flow channels if salt, oil mist 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 great increase
in the contamination, but never replaces the regular service work where the low and high-
pressure stages are completely dismantled and the compressors are mechanically cleaned.
