摘要： A one-piece, circular, power end seal for use in sealing gear boxes of heavy-duty reciprocating pumps. The power end seal generally includes a u-shaped, circular seal body having an open channel, a plurality of ribs tangentially mounted within the channel and a ring-shaped, fiber-filled dynamic seal being formed within an inner diameter wear surface of the seal body. The ribs generally provide the seal body with improved flexibility to maintain a constant and effective seal around connecting rods within the gear box, while at the same time retaining sufficient resilience to maintain static interference in a packing gland within the gear box. The inner diameter dynamic seal can be filled with PTFE, bronze filled PTFE, carbon filled PTFE or aramid fiber filled HNBR, which reduces heat build up and seal wear, while minimizing the radial squeeze of the seal in contact with the circumference of the connecting rod.
摘要翻译：一体式，圆形的动力端密封，用于密封重型往复泵的齿轮箱。动力端密封件通常包括具有开放通道的U形圆形密封体，切向安装在通道内的多个肋，以及形成在密封件的内径磨损表面内的环形纤维填充动态密封件身体。肋通常为密封体提供改进的灵活性，以在齿轮箱内的连杆周围保持恒定和有效的密封，同时保持足够的弹性以保持齿轮箱内的填料压盖的静态干扰。内径动态密封可以填充PTFE，青铜填充PTFE，填充碳的PTFE或芳族聚酰胺纤维填充的HNBR，从而减少热积聚和密封磨损，同时最小化与连杆的圆周接触的密封件的径向挤压。

摘要： A shaft sealing apparatus is provided which can easily be assembled and arranged to prevent leakage of a dope from an acetylator or the like system. A screw sleeve 12 having a spiral groove 16 provided in the outer side thereof is mounted on a rotary shaft 2 adjacent to a location where the rotary shaft 2 extends through a housing. As the screw sleeve 12 rotates together with the rotary shaft 2, it can return back the dope into the housing thus providing a sealing effect. The screw sleeve 12 comprises six segments fabricated by separating circumferentially into two and axially into three. The six segments 18, 20, 24, 26, 33, and 35 are jointed together to assemble a generally cylindrical structure on the rotary shaft 2. The assembling process can easily be conducted from two radial directions on the rotary shaft 2 between the housing and each bearing unit supporting the rotary shaft without disassembling the bearing units.

摘要： Preferred rod/piston assemblies (50, 50null, 150) comprise unitary rod members (52, 52null, 152) and compression rings (54, 54null, 154). In accordance with one preferred embodiment (50), the unitary rod member (52) comprises a connecting rod portion (60), a lower bezel portion (62) and a knob portion (66). The lower bezel portion (62) and the compression ring (54) define facing surfaces (82, 106) along which the compression ring (54) is secured to the unitary rod member (52). In accordance with a preferred method of manufacture, one or both of the facing surfaces (82, 106) are chemically treated to promote coupling of the compression (54) ring to the lower bezel portion (62). The unitary rod member (52) and the compression ring (54) are positioned in the mold or press with the compression ring (54) fitted over the knob portion (66) of the unitary rod member. Elevated temperature and pressure are applied to secure the compression ring (54) to the lower bezel portion (62). Among the advantages of the preferred structure are minimization the number of parts which must be supplied to form the preferred rod/piston assemblies (50, 50null, 150) and simplification of the processes for their construction.

摘要： In a gas turbine having a chordal hinge seal between an inner rail of each nozzle segment and an annular axially facing sealing surface of a nozzle support ring, a supplemental seal is disposed between the support ring and inner rail of the nozzle segment on a lower pressure side of the chordal hinge seal. The supplemental seal comprises a segmented annular composite tubular woven compliant seal disposed in a cavity along a sealing surface of the inner rail of the segment. The seal bears against the annular sealing surface of the nozzle support ring, which compresses the seal. Because of the compliant nature of the seal, a supplemental seal is formed on the low pressure side of the chordal hinge seal.

摘要： A high-pressure pumping system including an energizing seal component having an aperture extending therethrough and a seal jacket component having a base and a toroidally-shaped flared membrane extending from the base. The body and the flared membrane are monolithically formed of an inert polymeric seal material. The flared membrane extends through the aperture and encircles the energizing seal component to isolate the energizing seal component from fluid of the pumping system. The flared membrane may extend axially from the body and encircle the energizing seal component. The flared membrane may encircle the energizing seal component and overlaps a portion of the base. The seal jacket component may be formed around the energizing seal component. The seal jacket component may include a flange extending radially outwardly from the base.

The seal holder includes a first somewhat cuplike portion adjacent to the first seal retainer and a second somewhat cuplike portion more remote from the first seal retainer. The first somewhat cuplike portion opens in a second direction of motion opposite the first. The second somewhat cuplike portion opens in the first direction. The second seal retainer includes a first portion closer to the seal holder and a second portion more remote from the seal holder. The second somewhat cuplike portion of the seal holder receives the first portion of the second seal retainer.

摘要： Disclosed is a labyrinth seal assembly for sealing an annular gap defined between a bore of a housing and an outer surface of a cylindrical shaft, wherein the housing and shaft are relatively movable. The seal assembly includes radially inner and radially outer shield rings. The radially inner shield ring has an inner surface which is adapted and configured for support by the shaft. The radially outer shield ring is partially disposed within the sealing channel of the inner shield ring. The outer shield ring includes a casing member, foam seal elements, and a shield element retainer. The foam seal elements depend radially inward into the sealing channel so as to form a circuitous sealing labyrinth therein. The seal elements are formed preferably from polyurethane. A highly viscous fluid is disposed within the circuitous sealing labyrinth.
