Fluid transfer seal assemblies, fluid transfer systems, and methods for transferring process fluid between stationary and rotating components using the same

摘要

Fluid transfer seal assemblies (18) for transferring process fluid between a stationary component (12) and a rotating component (14), fluid transfer systems, and methods for transferring process fluid between the stationary and rotating components via a fluid transfer assembly are provided. A rotatable component (14) includes a sealing surface (17). The fluid transfer seal assembly (18) comprises a face seal ring (20) having at least one segment of a fluid passageway and a sealing face (28) configured to be disposed opposite of the sealing surface (17). The sealing face or the opposed sealing surface includes a geometric feature for forming a hydrodynamic seal therebetween. A secondary seal (22) is configured to be disposed between and contacting the face seal ring and the stationary component (12).
