摘要： A hydrodynamically lubricating seal has a generally circular seal body defining a static sealing surface and having a dynamic sealing lip projecting from the seal body for establishing sealing relation with a relatively rotatable surface. When compressed against a relatively rotatable surface, dynamic sealing lip defines a hydrodynamic geometry which wedges a film of lubricating fluid into the interface between the seal and the relatively rotatable surface in response to relative rotation. The dynamic sealing lip geometry maintains interfacial contact pressure within the dynamic sealing interface for efficient hydrodynamic lubrication and environmental exclusion, which enhances lubrication and environmental exclusion while permitting relatively high initial compression and relatively low torque. In abrasive environments, the improved exclusionary action results in a dramatic reduction of seal and shaft wear, compared to prior art, and provides a significant increase in seal life. The invention also increases seal life by making higher levels of initial compression possible, compared to prior art, without compromising hydrodynamic lubrication. This added compression makes the seal more tolerant of compression set, abrasive wear, mechanical misalignment, dynamic runout and manufacturing tolerances.

摘要： A hydrodynamically lubricating rotary seal for partitioning a lubricant from an environment has a generally circular seal body and sloping, generally opposed projecting static and dynamic sealing lips. The dynamic sealing lip is provided for establishing compressed sealing relation with a relatively rotatable surface, and has a sloping dynamic sealing surface that varies in width, and also has a hydrodynamic inlet curvature that varies in position around the circumference of the seal. When the seal is installed against a relatively rotatable surface, the dynamic sealing lip deforms to define a variable width interfacial contact footprint against the relatively rotatable surface that is wavy on the lubricant side, and wedges a film of lubricating fluid into the interface in response to relative rotation. The environment edge of the interfacial contact footprint is substantially circular, and therefore does not produce a hydrodynamic wedging action in response to relative rotation.

摘要： A hydrodynamically lubricated rotary seal or packing assembly which provides environmental exclusion, lubricant retention and hydrodynamic interfacial lubrication in applications where the environment pressure may be higher than the lubricant pressure. The invention is particularly suitable for oilfield drilling swivels and rotary mining equipment, and for applications such as artificial lift pump stuffing box assemblies and centrifugal pumps where a rotating shaft penetrates a pressurized reservoir which is filled with abrasive-laden liquids, mixtures or slurries. The invention provides a unique sealing mechanism which controls high pressure abrasive fluids, and which accomplishes hydrodynamic lubricant pumping activity to maintain efficient lubrication at the dynamic sealing interfaces thereof to thus significantly enhance service life. The invention provides a non-circular support surface which efficiently supports the non-circular flank of a hydrodynamic rotary sealing element against environmental pressure, thereby maintaining the integrity of the non-circular lubricant edge and the abrupt circular environment edge of the sealing element.

摘要： A swivel seal assembly is defined for providing sealed high pressure fluid communication between relatively rotatable generally coaxial conduits where dynamic runout and static misalignment may occur to one conduit relative to the other. A generally tubular washpipe is mounted in pivotally articulating relation to one conduit, and a generally tubular seal housing is telescoped over the washpipe and mounted in pivotally articulating relation to the other conduit. High pressure, staged rotary seals are supported by the seal housing and maintain bearing and sealing engagement with the washpipe so that the seal housing and washpipe articulate in unison in response to said static misalignment and dynamic runout, thereby virtually eliminating relative lateral motion between the seal housing and washpipe and minimizing rotary seal extrusion damage. The seal housing and washpipe are hydraulic force balanced regardless of the pressure to which they are subjected, and thus are not subject to pressure induced loads which might otherwise interfere with articulation.
摘要翻译：旋转密封组件被限定用于在相对旋转的大致同轴的管道之间提供密封的高压流体连通，其中一个管道相对于另一管道可能发生动态跳动和静态不对准。大体上管状的洗碗管以一个导管的方式铰接地安装，并且一个大体上管状的密封壳体被套叠在洗涤管的上方并以与另一导管的转动关节的方式安装。高压分级的旋转密封件由密封壳体支撑并且保持与洗涤管的轴承和密封接合，使得密封件壳体和洗涤水管响应于所述静态未对准和动态跳动而一致地铰接，从而实际上消除了密封件之间的相对横向运动外壳和洗碗管，并最大限度地减少旋转密封挤压损坏。密封壳体和洗涤水管是液压力平衡的，而与其受到的压力无关，因此不会受到压力引起的负荷，否则可能会干扰关节运动。

摘要： A hydrodynamically lubricated squeeze packing type rotary shaft with a cross-sectional geometry suitable for pressurized lubricant retention is provided which, in the preferred embodiment, incorporates a protuberant static sealing interface that, compared to prior art, dramatically improves the exclusionary action of the dynamic sealing interface in low pressure and unpressurized applications by achieving symmetrical deformation of the seal at the static and dynamic sealing interfaces. In abrasive environments, the improved exclusionary action results in a dramatic reduction of seal and shaft wear, compared to prior art, and provides a significant increase in seal life.The invention also increases seal life by making higher levels of initial compression possible, compared to prior art, without compromising hydrodynamic lubrication; this added compression makes the seal more tolerant of compression set, abrasive wear, mechanical misalignment, dynamic runout, and manufacturing tolerances, and also makes hydrodynamic seals with smaller cross-sections more practical.In alternate embodiments, the benefits enumerated above are achieved by cooperative configurations of the seal and the gland which achieve symmetrical deformation of the seal at the static and dynamic sealing interfaces. The seal may also be configured such that predetermined radial compression deforms it to a desired operative configuration, even through symmetrical deformation is lacking.

摘要： A laterally translatable pressure staged rotary shaft sealing mechanism having a seal housing with a shaft passage therein being exposed to a fluid pressure P1 and with a rotary shaft being located within the shaft passage. At least one annular laterally translatable seal carrier is provided. First and second annular resilient sealing elements are supported in axially spaced relation by the annular seal carriers and have sealing relation with the rotary shaft. The seal housing and at least one seal carrier define a first pressure staging chamber exposed to the first annular resilient sealing element and a second pressure staging chamber located between and exposed to the first and second annular resilient sealing elements. A first fluid is circulated to the first pressure chamber at a pressure P1, and a second staging pressure fluid is circulated to the second pressure chamber at a fraction of pressure P1 to achieve pressure staging, cooling of the seals. Seal placement provides hydraulic force balancing of the annular seal carriers.
