7.4.3 Principle of wet cleaning
Principle of wet cleaning
To clean the compressor stage during operation, water is injected before the compressor
wheel.
The water does not act as a solvent. The coating is removed by the mechanical action of the
impacting droplets. The process is particularly suitable as long as the contamination is not
too advanced.
CAUTION
Corrosion and deposits when cleaning
Salt water and cooling water treatment substances damage and adversely
affect turbocharger parts.
u Never use salt water, but only pure water for cleaning.
CAUTION
Volume of water
Uncontrolled volumes of water can damage the turbocharger and the en-
gine.
u Never connect the water line without the orifice specified for the tur-
bocharger.
