7 Periodic maintenance / 7.2 Cleaning the compressor during operation
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 fouling is not too ad-
vanced.
7.2.3 Prerequisites for wet cleaning of compressor
¡ Engine load of 50 ... 85%
CAUTION
Volume of water
Uncontrolled volumes of water can damage the pressure stages and the en-
gine.
Never connect injection tubes directly to a water pipe or a larger meter-
u
ing container other than that specified by Turbo Systems.
CAUTION
Corrosion and deposits when cleaning
Salt water and cooling water treatment substances damage and adversely
affect parts of the low-pressure and high-pressure stage.
Never use salt water, but only pure water for cleaning.
