SEAL HOUSING WITH FLANGE COLLAR, FLOATING BUSHING, SEAL COMPRESSOR, FLOATING POLISHED ROD, AND INDEPENDENT FLUID INJECTION TO STACKED DYNAMIC SEALS, AND RELATED APPARATUSES AND METHODS OF USE

摘要

Seal housings with flange collars, floating bushings, seal compressors, floating polished rods, independent fluid injection to stacked dynamic seals, and related apparatuses and methods of use. Embodiments are described that permit the polished rod to float within a tubular shaft, and the tubular shaft to float within a stationary housing, of a seal housing, to permit the seal housing to accommodate rod deviation from center. Flange collars are provided to facilitate the interconnection between seal housings and driveheads that previously were incompatible with one another.
