A CENTRIFUGAL SEPARATOR

The present invention provides a centrifugal separator (1) for separating at least one liquid phase from a liquid feed mixture-. The centrifugal separator (1) is comprising a frame (2), a drive member (3) and a rotating part (4), wherein the drive member (3) is configured to rotate the rotating part (4) in relation to the frame (2) around an axis of rotation (X), and wherein the rotating part (4) comprises a centrifuge bowl (5) enclosing a separation space (9). The centrifuge bowl (5) further comprises an inlet (14) for receiving the liquid feed mixture and at least one liquid outlet (6,7) for a separated liquid phase; wherein the separation space (9) comprises surface enlarging inserts (10) for increasing the separation performance. The centrifuge bowl (5) comprises a bowl wall (30), in which a first (31) and a second (32) channel extend, wherein the first (31) and second (32) channels extend in different directions (D1, D2) but intersect at an intersection point (Y) in which there is a fluid contact between said first (31) and second (32) channels. The first channel (31) is arranged such that during rotation of the centrifuge bowl (5), stress concentration regions (40) in the bowl wall (30) are generated on two opposing sides (31a, 31b) of the first channel (31) and lower stress regions (41) are generated in the bowl wall (30) on the other two opposing sides (31c, 31d) of the first channel (31), as seen in the cross-section in the plane (A) perpendicular to the direction (D1) of the first channel (31). The second channel (32) is arranged so that it intersects the first channel (31) with its center line (Z2) shifted towards a lower stress region (31c,d), as seen in the cross-section in the plane (A) perpendicular to the direction (D1) of the first channel (31). La présente invention concerne un séparateur centrifuge (1) pour séparer au moins une phase liquide d'un mélange d'alimentation liquide. Le séparateur centrifuge (1) comprend un cadre (2), un élément d'entraînement (3) et une partie rotative (4), l'élément d'entraînement (3) étant configuré pour faire tourner la partie rotative (4) par rapport au cadre (2) autour d'un axe de rotation (X), et la partie rotative (4) comprenant un carter de centrifugeuse (5) renfermant un espace de séparation (9). Le carter de centrifugeuse (5) comprend en outre une entrée (14) pour recevoir le mélange d'alimentation liquide et au moins une sortie de liquide (6, 7) pour une phase liquide séparée ; l'espace de séparati
