Surging of the compressor stage
Should repeated surging of the compressor stage occur during compres-
sor cleaning, first the cleaning parameters as well as the engine-side sys-
tem must be checked with regard to deviations (e.g. an increased pres-
sure loss in the charge air cooler) and corrected if necessary.
If, despite correct settings, surging of the compressor stage occurs while
cleaning the compressor, as a remedial measure the engine load can be
reduced further while cleaning the compressor. The reduction of the en-
gine load can lead to a reduction in the effectiveness of the compressor
cleaning.
To avoid a decreased engine availability, the compressor stage can be
cleaned at reduced engine load during the drying time after wet clean-
ing of the turbine has been completed. (see section Wet cleaning tur-
bine and nozzle ring during operation). In this case, the water injection
time for cleaning the compressor can be increased from ten to forty
seconds.
