摘要： A pair of Northey rotors for a vacuum pump, in which each rotor comprises two opposing, substantially parallel faces, and a peripheral surface located between the opposing faces. In order to reduce damage caused by pumping a gas stream containing liquid or solid particulates, a plurality of grooves is located on the peripheral surface for accommodating the particulates.

摘要： A seal assembly for the protection of a static seal device for use in a vacuum pump. The seal assembly comprising at least two components which are sealingly connected together, an o-ring seal, which is engaged between the two components to prevent transfer of fluid to and from the pump between these two components and a fluid channel. The fluid channel being in the plane of the o-ring and located between the o-ring seal and a process gas flow path. The fluid channel provides a path for a barrier gas to be routed when the apparatus is in use. The channel being connectable to an external source of barrier fluid and having an outlet in fluid communication with the pump swept volume.
摘要翻译：一种用于保护用于真空泵的静态密封装置的密封组件。密封组件包括密封地连接在一起的至少两个部件，O形圈密封件，其接合在两个部件之间以防止流体在这两个部件之间和/或从泵两者之间传递流体通道。流体通道位于O形环的平面内并且位于O形环密封件和工艺气体流动路径之间。当设备使用时，流体通道提供用于阻挡气体被路由的路径。该通道可连接到外部的阻挡流体源并且具有与泵扫过体积流体连通的出口。
