Recirculating Cooling Water
The cooling system consists of a closed cooling water circuit with a cooling water volume which must
be kept constant by topping up, depending on the evaporation loss. The checking of the recirculating
cooling water level has to occur at the expansion tank.
Modern Diesel engines put particular requirements on the recirculating cooling water due to the
increased power desity and the consequently increased heat to be dissipated.
These requirements can only be met by proper prepared, monitored and maintained cooling water.
If the the preperation, monitoring and maintenance work are not carried out properly, even a short
period of operation may result in damages due to corrosion.
Three decisive facts are to be considerd for a proper treatment:
•
Suitable fresh water
•
effective corrosion inhibiting agent
-
corrosion inhibiting oil, soluble
-
chemical corrosion inhibiting agent (chemicals)
•
exact dosing
of the corrosion inhibiting agent
Requirements for the cooling water
Always use clear, clean water. Suitable are:
-
Natural water (deep well-, well water)
-
condensate and
-
fully de-ionized water.
The values for the fresh water analysis must be within the following limits:
