MAB Solids-retaining Centrifugal Separator0 pages
Application
Purification or clarification of mineral oils used in marine
installations and power stations (fuel and lubricating oils).
Working principle
Separation takes place in a solids-retaining bowl that can be
arranged for either clarification or purification. In both cases,
the contaminated oil is fed into the separator through the
centre, and it is separated by centrifugal force into its various
phases, the heaviest phase (sludge and water) being forced
outwards to the periphery of the bowl. The accumulation of
sludge is periodically removed from the bowl by hand.
Installation
The oil is pumped, heated, and separated as shown in the
figure. A liquid seal in the separator bowl prevents the oil from
escaping through the water outlet. If this seal is broken, an
alarm device is activated. With unmanned engine rooms, the
signals are transmitted to a remote control unit. When the
seal is broken, the three-way valve shuts off the oil feed and
the oil is recirculated until the fault is corrected.
