5 Maintenance / 5.2 Cleaning the compressor during operation

Cleaning method

Cleaning the compressor while in operation is carried out as wet clean-
ing. This cleaning method is tested and approved by ABB Turbocharging.

Principle of wet cleaning

To clean the compressor stage during operation, water is injected in
front of the compressor wheel through an injection pipe fitted in the fil-
ter silencer or the suction branch.

The water does not act as a solvent, but the contamination deposit is re-
moved by the mechanical impact of the droplets. This is a very suitable
process, provided that the degree of contamination is not too high.

 CAUTION

Corrosion and deposits when cleaning

Damage and impairment of turbocharger parts due to salt water and
cooling water additives

u

Don't use salt water for cleaning, but only clean fresh water.

 CAUTION

The injection pipe must on no account be connected directly via a cock
to a water pipe or a dosing vessel larger than the one supplied. This
prevents uncontrolled volumes of water entering the turbocharger and
engine, which can lead to serious damage.

V-engines

In the case of V-engines with several turbochargers on each engine, we
recommend parallel cleaning of the compressors. This cleaning process
is faster and the risk of turbocharger surging is reduced.

Sequential charging

In the case of sequential charging, care must be taken to ensure that tur-
bocharger compressors are cleaned regularly, especially after periods of
operation in the lower performance range.

5.2.1

Wet cleaning compressor using external water
pressure vessel (XC1)

Approval by enginebuilder

These instructions for wet cleaning only apply when cleaning is carried
out with clean water and under the precondition that the enginebuilder
approves the process.

NOTICE

Supplying water from the externally mounted water vessel is suitable
only for those applications where a negative pressure exists in front of
the compressor wheel (not used for: blowers connected in front of the
compressor or high-pressure compressor stages with two-stage char-
ging).
