摘要： A segment of a seal assembly for sealing a higher pressure area from a lower pressure area is disclosed. The segment comprises a radial external surface, a radial internal surface for sealing against a rotating member, a transverse groove for maintaining a pressure around portions of the segment, and one or more pads including a scooping groove. The scooping groove is positioned at or in proximity to an edge of the transverse groove and provides for a transition flow between the one or more pads and the transverse groove.

摘要： A segment of a seal assembly for sealing a higher pressure area against a rotating member is disclosed. In an embodiment the segment comprises a radial external surface, a radial internal surface for sealing against a rotating member, a feed cavity, a ramp portion in communication with the feed cavity, a segment trough in communication with the ramp portion, one or more hydrodynamically-configured pads including an entrance; and a sealing dam disposed between the lift pad and the radial internal surface. In an embodiment of the segment, the ramp portion is configured to pick up air flow with an increase in velocity from said rotating member, and the trough or a flow-control portion is configured to prevent fluid from flowing around or circumventing the pad entrance to, at least in part, provide a dynamic feed.

摘要： A segment of a seal assembly for sealing against a rotating member is disclosed. The segment includes a radial external surface, a radial internal surface for sealing against said rotating member, a face groove, and a secondary sealing surface. In embodiments, the segment may include a radial feed groove, and the face groove has an axial depth from the surface of the secondary sealing surface that is greater than the axial depth of the radial feed groove. Additionally, in embodiments, the face groove may include a relief groove, the face groove has a radial length at the axial position of the secondary sealing surface, the relief groove is axially offset from the secondary sealing surface, and the relief groove includes a portion with a radial length greater than the radial length of the face groove at the axial position of the secondary sealing surface.
