<p>A centrifugal separator for separating two liquid components has normally continuously open outlets for both liquid components, an interface layer formed in the separating chamber between the separated liquid components being maintained at a predetermined radial level. There is provided a special arrangement for the continuous discharge of the light liquid component but intermittent discharge of the heavy liquid component. For this purpose a first outlet channel in the centrifuge rotor for the heavy liquid component communicates through a calibrated opening with a stationary second channel outside the rotor, the second channel including a shut off valve. Apparatus is arranged to indicate when an interface layer formed in the separating chamber of the rotor between the separated liquid components has moved radially inwards to a certain level. A control unit is arranged on a signal from the apparatus to keep the valve open until the desired amount of heavy liquid component has been discharged from the separating chamber to move outwardly the interface layer.</p> |
