WinGD X92-B - Cooling water system

4.2 Cooling water system
The cooling water system supplies the items that follow with cooling water:
•
Cylinder liner
•
Cylinder cover
•
Exhaust valve cages
•
Scavenge air cooler (SAC).
For the schematic diagrams, refer to section 13.1 Schematic diagrams - general.
The cooling water system has the engine connections as interface to the plant as follows (in Figure
4-2 marked with a circle):
•
Connection 01 (cylinder cooling water inlet)
•
Connection 02 (cylinder liner cooling water inlet (bypass cooling water system)) (optional)
•
Connection 03 (cylinder cooling water outlet)
•
Connection 05 (cylinder cooling water drain outlet)
•
Connection 07 (SAC LT-cooling water inlet) (not shown)
•
Connection 08 (SAC LT-cooling water outlet) (not shown).
If the supply at the engine connection 02 is installed, the cylinder liner is supplied with cooling
water at a higher temperature than the cylinder cover.
The cooling water system has the parts that follow:
•
Automatic venting unit
The automatic venting unit (001) constantly releases unwanted air from the cooling water.
•
Optional vent valve
The optional vent valves (008) can be used manually to release unwanted air from the
cooling water, if the automatic venting unit (001) does not operate correctly.
•
Vent valve
The vent valves (009) constantly release cooling water to the automatic venting unit (001)
to release unwanted air from the cooling water.
•
Vent valve
The vent valve (010) can be used manually to release unwanted air from the cooling water,
if the automatic venting unit (001) does not operate correctly.
