Abstract
The invention relates to a centrifugal separator, in which centrifugal treatment is intended to take place at an overpressure, and has for its main object to guarantee wetting and cooling of annular sealing means (16) in connection with the starting of the centrifugal separator, the sealing means being arranged around the rotor outlet for separated liquid between the rotor and a stationary receiving device. The object is obtained according to the invention by having means (22) for supply of a small amount of liquid to an outlet chamber (15) of the rotor already before the separation chamber (6) of the rotor is filled up with liquid, the outlet chamber (15) being connected with the separation chamber (6) via an overflow outlet (14). The means (22) is arranged to supply liquid to the outlet chamber (15) via a connection, which is separated from the separation chamber and is extending through the stationary receiving device. By means of a stationary outlet member (17) provided with a special passage (20) the small amount of liquid supplied to the outlet chamber (15) can be circulated in contact with the annular sealing means (16) during the starting up of the centrifugal separator.
