5.3 Cleaning the compressor during operation (part-2)

5.3.1 Wet cleaning the compressor with external pressurised water container

(XC3)

 

NOTE
The water feed with the externally mounted dosing vessel is only suitable for applications with underpressure upstream of the compressor wheel (cannot be used for: Blower connected upstream of the compressor or high-pressure compressor stage in the case of two-stage charging).

Operating state preconditions for cleaning compressors with XC3

NOTE
In order to carry out a successful cleaning procedure that has been tested and is recommended by ABB Turbo Systems, the following preconditions must be met: - Engine warm from running (engine under full loading as far as possible) -High turbocharger speed - Cleaning cycle started according to the following description in Procedure for wet cleaning with XC3.

                              Procedure for compressor wet cleaning with XC3

A	Screw plug
B	Valve lever

Operating the pressure water vessel

-The Operating state preconditions for cleaning compressors with XC3 must be met before cleaning can begin.

- Remove the screw plug (X).

- Fill the vessel with pure water.

- Tighten screw plug (X).

- Actuate valve lever (Y) against the spring and hold it for 10 to 15 seconds until all the water has been injected.

- After cleaning, a waiting time of at least 5 minutes is necessary to allow the turbocharger to dry.

NOTE
If the cleaning operation is unsuccessful, it can be repeated up to 2 times. If cleaning is still unsuccessful after three attempts and the engine operating values are unsatisfactory, we recommend that the turbocharger be checked and cleaned by an official ABB Turbo Systems service station.
