2. Cleaning the high-pressure turbine stage (HP stage)
If present, open the drain pipe in the low-pressure stage during cleaning.
Switch the 3-way valve during cleaning from scavenging air to water supply.
Carry out the cleaning process with cleaning parameters according to the specifications in
the following table.
Water pressure
(guideline value)
[bar]
Duration of water injection
[min]
850 HP 20 ±1 3.0 10
Table 11: Cleaning parameters HP
For an optimum cleaning result, the water flow rate adopted when designing
the cleaning process should be set via the corresponding control valves and
monitored by a flowmeter. If this is not possible, the specified water pressure
at the cleaning connection of the turbocharger is to be set as a rough ap-
proximation.
3. Cleaning the low-pressure turbine stage (LP stage)
If present, open the drain pipe in the low-pressure stage during cleaning.
Switch the 3-way valve during cleaning from scavenging air to water supply.
Carry out the cleaning process with cleaning parameters according to the specifications in
the following table.
Water pressure
(guideline value)
[bar]
Duration of water injection
[min]
850 LP 20 ±1 1.5 10
Table 12: Cleaning parameters LP
For an optimum cleaning result, the water flow rate adopted when designing
the cleaning process should be set via the corresponding control valves and
monitored by a flowmeter. If this is not possible, the specified water pressure
at the cleaning connection of the turbocharger is to be set as a rough ap-
proximation.
