Abstract
Control unit for a self-emptying centrifuge having a fluid controlled emptying valve for discharging the solids and a paring disc or a conduit sealingly joined to the drum for removal of a specifically heavier liquid and an outlet for a specifically lighter liquid, for displacement of the specifically lighter liquid from the drum before the emptying valve is opened. The control unit operates so that flow in the outlet for specifically heavier liquid is reduced whereby specifically lighter liquid is displaced from the centrifuge, and so that thereafter the emptying valve is opened.
