Abstract: In a seal or bearing that uses the tapered-sleeves-with-spiral-groove technology, the capacity is increased, without increasing the space envelope, by folding the tapered surfaces. Double and triple folding is illustrated. The seal/bearing may be used in e.g. a rotary impeller pump, or as a big-end bearing.

Abstract: For an impeller pump, the seal/bearing unit has two rotor-stator pairs of tapered sleeves arranged back-to-back. The sleeves have a spiral groove, and convey barrier-liquid from an entry-mouth in an entry-chamber to an exit-mouth in an exit-chamber. Having two sleeves gives the units mechanical stability, trust support capability, and resistance to vibrations and other abuses. The tapered sleeves may be arranged wide-narrow-wide, or narrow-wide-narrow. The sleeves may be mounted for sliding in the housing and on the shaft, or may be fixed to the housing or shaft.

Abstract: Apparatus to enhance performance of sequentially-deployable lip seal assemblies. In certain embodiments, biasing members to ensure deployment of sequentially deployable lip seals include an o-ring mounted within a cartridge or housing of one or more yet-to-be- deployed lip seals, with the o-ring disposed immediately adjacent one of the lip seals. When a barrier member or deployment sleeve is interposed between the one or more yet-to-be- deployed lip seals and a shaft, such as a rotating and/or reciprocating shaft of a stuffing box, the o-ring biases the lip seal toward the outside diameter of the shaft. Upon movement of the barrier member or deployment sleeve to a position exposing the Hp seal to the shaft, the o- ring urges the lip seal into engagement with the outside diameter of the shaft. A pressurized fluid may be employed between the housing and the o-rings. Flush paths, multi-part housings, and baffle-type housings are also disclosed.

Abstract: Advantageous seal systems (2000) are provided that include a barrier member movable relative to a shaft (2024) to allow sequential engagement of resilient seat members (2034), e.g., lip seals, with the shaft. Movement of the barrier member (2036) may be effected manually or through introduction of pressurized fluid to effect piston-like movement. The disclosed seal assemblies may include an automatic leak detector and may utilize such leak detection to effectuate automatic movement of the barrier member. The barrier member may be moved relative to the shaft while the shaft is in movement, e.g., rotating or reciprocating, thereby permitting seal maintenance without interruption in operation. As seal members are sequentially brought into sealing engagement with the shaft, the previously engaged seal members contribute to the sealing performance of the seal assembly, although no longer effective to establish a stand-alone seal with the shaft. Front and rear bushings (2002,2004) may be provided within the seal system.

Abstract: For fitment into the stuffing box of a centrifugal pump. A spiral-groove is cut on the outer surface of the rotor of a pair of tapered bearing surfaces. The groove is 0.02 mm deep, 2 mm wide, and its circumferential length is 50 cm. Barrier-liquid is fed to an entry-mouth of the spiral-groove, and groove generates a pressure in the stuffing box high enough to overcome process pressure. The barrier-liquid may be water. The interface between the bearing surfaces is sealed from the process-fluid and from the outside.

Abstract: This invention relates to a seal cartridge (120) comprising at least two back-to-back lip seals. A first, generally L-shaped sleeve (110) is applied against the back wall of the seal ring (121) such that its axially extending cylindrical surface (111) retracts the lip portion of the outboard seal into a non-deployed position. A second, generally L-shaped sleeve (140) is fitted up against the back of the first sleeve so as to place the lip end of the inboard seal in a similarly raised or retracted position. Upon installation of the seal ring about the shaft and in the shaft housing, the second, innermost sleeve is removed, such that the inboard lip seal is deployed against the surface of the shaft (130). Upon detection of leakage past the inboard seal, the first sleeve is retracted to thus deploy the remaining outboard lip seal (122).

Abstract translation: 本发明涉及一种包括至少两个背对背唇形密封件的密封盒（120）。 第一大致L形的套筒（110）被施加在密封环（121）的后壁上，使得其轴向延伸的圆柱形表面（111）使外侧密封件的唇部缩回到非展开位置。 第二个通常为L形的套筒（140）装配在第一套筒的背面上，以便使内侧密封件的唇端部处于类似的升起或缩回位置。 当密封环围绕轴安装在轴壳体中时，第二最内侧的套筒被移除，使得内侧唇形密封件抵靠轴（130）的表面展开。 当检测到通过内侧密封件的泄漏时，第一套筒缩回，从而展开剩余的外侧唇形密封件（122）。
