Abstract

The present invention provides a method for determining if air is trapped within a centrifugal separator (100). The separator comprises a stationary frame (30), a rotatable assembly (101) and a drive unit (34) for rotating the rotatable assembly (101) relative the frame (30) around an axis of rotation (X); and further a feed inlet (20) for supply of a liquid mixture to be separated, a first liquid outlet (21) for discharge of a separated liquid phase and a second liquid outlet (22) for discharge of a heavy phase having a density that is higher than said liquid phase; wherein the rotatable assembly (101) comprises a rotor casing (2) enclosing a separation space (17) in which a stack (19) of separation discs is arranged to rotate around a vertical axis (X) of rotation. The method comprises the steps of a) closing one of the first (21) and second (22) liquid outlets and restricting the flow from the other outlet; b) supplying feed to the feed inlet (20) and measuring the flow to the feed inlet (20) and the flow from the restricted outlet (21,22); c) comparing the flow as a function of time between feed inlet (20) and the restricted outlet (21,22); and d) determining that air is trapped within the centrifugal separator (100) if the measured flow as a function of time flow deviates between feed inlet (20) and the restricted outlet (21,22).
