B.8 Coolant connection block at generator housing<br />
Monitoring of the coolant connection block as sacrificial anode<br />
At all raw watercooled gensets the coolant connection block at the side of the generator housing<br />
must be well controlled. This coolant connection block is manufactured from a special aluminum<br />
alloy and serves also as sacrificial anode. If by the influences of electrical DC voltage the aluminum<br />
alloy of the generator is endangered, first the coolant connection block is concerned. If visibly<br />
corrosion is identifiable from the outside of the coolant connection block, the block must be<br />
changed in regular intervals (at least once per year). In this case the coolant connection block is<br />
to be seen as wearing part. It should always be available in each case as spare part on board.<br />
In order to protect the generator housing<br />
against corrosion and against elecrolysis,<br />
the connection block with the cooling<br />
water connecting pieces takes the function<br />
of a sacrificial anode.<br />
Replacement of the coolant connection block<br />
The coolant connection block is put on with a "Spezial" sealant. The fixing bolts are not intended<br />
in order to stretch the coolant connection block closely on the surface area. These screws serve<br />
only for the adjustment of the coolant connection block until the sealant is hardened and it reached<br />
its final firmness. The fixing bolts may be tightened therefore only sturdy.<br />
ATTENTION! At the side the fixing bolts with an electrically neutral fat (e.g. anti seize)<br />
must be used. If the fixing bolts (high-grade steel) turned in without this fat into the aluminum<br />
threads, the danger of a corrosion exists, and it is possible that the thread root out<br />
when unscrewing the screws.<br />
