4.5 Separating function 4 Design and function
4.5.2 Liquid flow
Unseparated oil is fed into the bowl through the
inlet pipe and travels via the distributor towards
the periphery of the bowl.
When the oil reaches slots in the distributor, it
rises through the channels formed by the disc
stack, where it is evenly distributed.
The oil is continuously cleaned as it travels
towards the centre of the bowl. When the
cleaned oil leaves the disc stack, it flows through
a number of holes in the distributor and enters
the oil paring chamber. From here it is pumped
by the oil paring disc, and leaves the bowl
through the oil outlet. Separated water, sludge
and solid particles, which are heavier than the
oil, are forced towards the periphery of the bowl
and collect in the sludge space.
The space between the bowl hood and top disc,
as well as the water paring chamber, is filled
with oil, which is distributed over the entire
circumference via the grooves in the top disc.
During normal operation-, the water drain valve
in the water outlet is closed.
