摘要： The present invention provides seal assembly (1) for providing a seal between a first zone (2) and a second zone (3), comprising a rotatable sealing member (4) comprising a first sealing ring (5), a stationary sealing member (6) comprising a second sealing ring (7) and means (8) for bringing the first and second sealing rings into engagement with each other. The first and second sealing rings are arranged so that a double contact seal having at least one chamber (11) arranged at a radial plane (p) is formed upon engagement between the first and second sealing rings (5, 7). The seal assembly further comprises at least one fluid connection (15) to said chamber (11). The present invention further provides a centrifugal separator comprising such a seal assembly.

摘要： A centrifugal separator for separation of at least two components of a fluid mixture which are of different densities. The centrifugal separator comprises a rotor 22 rotatable about an axis of rotation X and comprising a rotor wall 2, 3 which surrounds an inner space with a separating chamber within the rotor 22. The rotor wall 2, 3 is divided into an upper bowl hood 3,with an end portion 4,and a lower bowl body 2 which are dismountably attached to each other. The centrifugal separator further comprises an inlet for feeding the fluid mixture into the rotor's 22 separating chamber, at least one outlet for discharging out from the rotor 22a component separated from the fluid mixture, and a rotor shaft attached to the rotor 22 and drivably connected to a motor for rotation of the rotor 22 about the axis of rotation X. The bowl hood 3 and said bowl body 2 are dismountably attached to each other by an annular flange portion 5 of said bowl hood 3resting on a stop flange 6 of said bowl body 2. The rotor 22 comprises a pressure media supply port 14 for supplying pressure media to a space between said annular flange portion 5, having a lower free end surface 16, and said 1 stop flange 6 when dismounting said bowl hood 3 from said bowl body 2 where said pressure media is acting on said lower free end surface 16 for displacing said bowl hood 3 upwards out of said attachment from said stop flange 6.
摘要翻译：用于分离具有不同密度的流体混合物的至少两种组分的离心分离器。离心分离器包括可围绕旋转轴线X旋转的转子22，转子22包括转子壁2,3，转子壁2,3在转子22内包围具有分隔室的内部空间。转子壁2,3分成上碗罩3 具有可拆卸地彼此附接的端部4和下碗体2。离心分离器还包括用于将流体混合物供给到转子22的分离室中的入口，用于从转子22a排出与流体混合物分离的部件的至少一个出口以及附接到转子22并且可驱动地连接到用于转子22围绕旋转轴线X旋转的马达。碗罩3和所述碗体2通过所述碗罩3的环形凸缘部分5可拆卸地彼此附接，所述碗形罩3支撑在所述碗体的止挡凸缘6上转子22包括一个压力介质供应口14，用于向所述环形凸缘部分5之间的空间供应压力介质，具有一个下部自由端表面16和所述一个止动凸缘6，当从所述碗体上拆下所述碗罩3时其中所述压力介质作用在所述下部自由端表面16上，用于将所述碗罩3从所述止动凸缘6向上移出所述附件。

摘要： The disclosure concerns a modular centrifugal separator system (2) comprising a base unit (4) and arranged therein an exchangeable separation insert (6), an exchangeable tube kit (8), and an interface (10) for fluid communication between the exchangeable separation insert (6) and the exchangeable tube kit (8). The exchangeable separation insert (6) comprises a rotor casing (52) forming a separation space (54), and a first half (101) of the interface (10). The exchangeable tube kit (8) comprises at least one tube (22, 24, 26) for one of the liquid feed mixture, the heavy phase, and the light phase, and a second half (102) of the interface (10). The modular centrifugal separator system (2) comprises a removable sealing member (12) covering the first and/or second half (101, 102) of the interface (10).
