2. Function
The cooling water pump supplies cooling water, through the supply pipe (1) on the
exhaust side, to the cylinders. The cooling water flows through the cylinder liner (2),
water guide jacket (3), cylinder cover (4) and exhaust valve cage (5). The vent
unit (16) and ball cock (19) stay open during operation, which makes sure that the
system continuously releases air.
Note: If problems occur, see the instruction plate on the vent unit (1).
The water flows from the outlet pipe (9) through a temperature control valve to the
cooler and back to the pump. A balance pipe connects the suction side of the pump to
the expansion tank. This balance pipe makes sure there is static pressure and
adjustment for the expansion and decrease of water.
A throttle (6) is installed in the outlet pipe of each cylinder. The throttle controls the
flow rate of cooling water through the cylinder.
The adjustable throttle (10), installed in the outlet pipe (9), controls the pressure in the
system.
2.1 Drain
You can use the shut-off valves (7) and (11) to isolate each cylinder from the cooling
water system. The ball cock (12) is used to drain water from the cylinder(s).
Note: If only the cylinder cover is removed, it is not necessary to open the ball
cock (12) because cooling water will flow through the bypass pipe (13).
