Water cooling faults

The following table shows the possible causes of and remedial measures for faults on water-

cooled machines.

Table 8-3

Cooling system faults

↓ Overheating

↓ Water leaking

Possible causes of faults

Remedial measures

Reduced cooling

Check the cooling water flow, increase the amount of cooling water if

necessary.

Cooling water flow rate too low

Consult the manufacturer. If the specified cooling water quality is ob‐

served, the cooling system is maintenance-free.

Inlet temperature too high

Set the correct upstream temperature.

Cooling water supply switched off

Switch on the cooling water supply.

Cooling water contains too many or unsuit‐

able antifreeze and corrosion-protection

agents

Use cooling water of the agreed quality.

X Leaks in the cooling system

Consult the manufacturer.

X Defective cooling water connection

Find the leak and seal it.
