-- The filter element is damaged.
-- After the filter element is cleaned, it still gives alarm.
-- To replace the element after being cleaned for 3-6 times, select high-
quality ones, which can ensure the reliability of diesel engine.
Therefore, it is suggested to purchase the origin parts.
5.9 Use and maintenance of diesel fuel filter
Diesel fuel filter consists of strainer and fine filter. As the time goes by, the
dirt or foreign material becomes increasingly accumulated on the filter
element surface and bottom of housing, which can clog the element if it is
not removed timely. As a result, diesel engine can
’
t be provided with
sufficient fuel, reducing the power. Therefore, it is important to periodically
maintain or clean the diesel fuel filter.
a.
Periodically open the drain plug at the bottom of housing to drain the
dirty fuel or accumulated water.
b.
Generally, filter element should be maintained once every 200-300h,
and shortened if the fuel quality is poor. During maintenance, timely
replace any damaged filter element.
c.
Before maintenance, block the two holes on the main element to prevent
any dirt from getting in. The filter element should be cleaned in clean
kerosene and diesel fuel by a soft brush. After that, use clean kerosene
and diesel fuel to clean it again. If conditions permit, use clean
compressed air to blow it from the inside to the outside.
d.
Use clean kerosene or diesel fuel to clean the inside surface of housing
and each hole of end cover.
e.
Check each sealing is damaged, if so, timely replace it.
f.
After maintenance and before use, check there is fuel leakage at each
sealing position.
5.10 Use and maintenance of fresh-water cooler
The fresh-water cooler for WP10 series diesel engine is of shell-and-tube
heat exchanger of which principle is that the seawater flowing in the coolant
pipe cools the fresh water circuitously going in the inside of shell. Thus that
can optimize the cooling conditions of diesel engine and then improve the
useful life of diesel engine.
