Wet cleaning procedure for turbine during operation
Meet prerequisites and operating state requirements without fail before
cleaning!
Make sure water supply (01) is connected, turned on and guaranteed.
Open drain pipe (08, 09), if provided.
Switch over 3-way valve (04) from scavenging air mode to water sup-
ply.
Set the required volume of water on the flowmeter as shown in the ta-
ble (see table Cleaning parametersTPL-C: 3 nozzles - Cleaning pa-
rameters for wet cleaning of turbine and nozzle ring).
After injecting required volume of water, shut off water supply again by
switching over 3-way valve (04) to scavenging air mode.
The injection process has been completed.
Close drain hole (if provided) above drain pipe (08, 09).
After cleaning, wait with engine running for at least 10 minutes without
changing load to allow turbocharger to dry.
