Solids-retaining Centrifugal Separator 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. 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 separator model MAB 103B complete with feed/discharge pump the oil Is recirculated until the fault Is corrected. and fittings for connection to a preheater.

Water outlet MAB bowl arranged as a clarifier for separating oils containing sludge and a very small quantity of water. MAB bowl arranged as a purifier for separating oils containing sludge and an appreciable quantity of water. Standard design Solids-retaining separator comprising a frame containing in its lower part a horizontal drive shaft with friction clutch and brake, worm gear and a vertical bowl spindle. The worm gear is placed spindle inside the space formed by the upper part of the frame and the frame hood which also carries the feed and discharge systems. The frame hood is hinged to...
