摘要： A centrifugal separator and a method of operating the separator are disclosed. The separator comprises a centrifuge rotor (4) having a rotor wall (7) enclosing an inner space (8) containing a stack of separation disks (9). The rotor comprises an inlet (10) for a product, a first outlet (11) for a light phase of the product, and a second outlet (12) for a heavy phase of the product. The second outlet comprises a plurality of outlet channels (14) extending along an inner side of the rotor wall from an outer region (8a) towards an inner region (8b) of the inner space. Each outlet channel transports a flow of the heavy phase from the outer region. The separator comprises a plurality of temperature sensors (20) provided at a respective outlet channel. Each sensor senses a temperature in the proximity of the respective outlet channel and provides a signal representing the sensed temperature.

摘要： 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).

摘要： A centrifugal separator (1) comprising a rotor arrangement (2) and a drive arrangement (5) is disclosed. The centrifugal separator (1) comprises a generator (14) for generating an electric current. The generator (14) is configured for continuously generating a current during a full revolution of the rotor arrangement (2). The current is utilised for supplying electric current to a user of electric energy (12) arranged in the rotor arrangement (2). An actuator (40) forms at least part of the user of electric energy (12).

摘要： The present invention provides a separation system (120) comprising a centrifugal separator (100) for separating a liquid feed mixture, wherein the centrifugal separator (100) is arranged for separating the liquid feed mixture into at least one separated liquid phase and discharging said at least one separated liquid phase. The separation system (120) further comprises a flow measurement arrangement (90) arranged for receiving a measurement liquid; said measurement liquid being either the liquid feed mixture or a separated liquid phase. The flow measurement arrangement comprises a first container (60) for holding measurement liquid; a first device (61) for measuring a parameter related to the weight of measurement liquid contained in said first container (60),a second container (70) for holding measurement liquid, a second device (71) for measuring a parameter related to the weight of measurement liquid contained in said second container (70), wherein the flow measurement arrangement (90) is further arranged to allow emptying said first container (60) of measurement liquid while a further container of the flow measurement arrangement (90) is being filled with measurement liquid and vice versa, thereby allowing alternately filling the first (60) and a further container of the flow measurement arrangement (90) with measurement liquid.
