Date Dec. 8, 1994Method in a centrifugal separator of regulating during operation the outlet flow through a stationary discharge device, which is arranged in an outlet chamber, of a separated liquid and a centrifugal separator to carry out the method. In order to accomplish a method and a centrifugal separator, which makes it possible to regulate the outflow of a liquid, which is separated in a centrifugal separator and discharged out of the same through a stationary discharge device within a wide flow range with small energy losses and with a small risk of rotor dynamical oscillations this outlet flow is regulated by bringing at least a portion of the separated liquid present in the outlet chamber (12) to rotate at a lower angular speed than the rotor in an angular zone (24) of the outer chamber, which is free from elements rotating with the rotor, and in which the inlet opening (19) is located, and by bringing liquid, which is present in this zone (24), to flow through at least one passage (26), which is delimited by elements (25) rotating with a rotor and which has an inlet (35) and an outlet (37) located outside this inlet (35) in the outlet chamber (12), when the free liquid surface is located radially inside a predetermined radial level (27), at which the inlet (35) of the passage is located. |
