Marine Diesel gensets. Operator’s Manual.
Maintenance task. Seawater filter inspection
It is important to install a seawater filter (supplied as accessory) between seawater cock and
the seawater pump to avoid that any impurity might clog the seawater circuit or seawater pump.
To clean this filter:
1.
Loose the cover top, turning it.
2.
Remove the filtering component and clean it.
3.
Fit it again taking care that the cover is well seated on the o-ring.
4.
Start the genset to check seawater leakages.
Maintenance task. Seawater pump impeller inspection
Seawater pump impeller is neoprene and cannot rotate dried. If operated without water, the impeller
can be broken. It is important therefore that a spare impeller is always available. Impeller inspection
and replacement procedure:
1.
Close the seawater cock.
2.
Remove the seawater pump cover plate.
3.
Remove the impeller from the shaft.
4.
Clean the housing.
5.
Inspect the impeller for damaged, cranked, broken,
missing or flattened vanes. The impeller vanes should be
straight and flexible.
1.
If it is damaged replace with a new one.
6.
Lubricate the impeller with soapy water before installation.
7.
Install the impeller. During installation push and rotate the impeller in the same direction as
the genset rotation until it is thoroughly seated in the impeller housing.
8.
Inspect the cover plate and gasket for corrosion and/or damage. Replace components as
necessary.
9.
Lubricate the gasket with silicon grease and attach the gasket and cover plate to the
seawater pump housing.
10.
Open the seacock.
11.
Start the genset and check for leaks.
Maintenance task. Zinc anode inspection
In order to avoid the corrosion produced by
galvanic currents, the genset is fitted with a zinc anode
located on the front lid of the coolant-seawater heat
exchanger. Anticorrosion zinc anode inspection and
replacement:
1.
With the genset cooled, close the seacock, open
the coolant drain plug and drain the coolant into a
suitable container.
2.
Remove the anticorrosion zinc anode (plug) from
the heat exchanger.
3.
Use a wire brush to remove the loose corrosion on
the anticorrosion zi nc anode.
