Piston Pump With Leak Diagnostic Port

Номер: US20120097026A1
Автор: John Angelosanto, Joshua A. Shreve, Neal B. Almeida
Принадлежит: Waters Technologies Corp

Described are embodiments of a pump having a diagnostic port that enables users and support personnel to diagnose the source of a pump leak. The diagnostic port is monitored visually or with a pressure or liquid detection sensor. In some embodiments, fluid detected at the diagnostic port corresponds to a leak around a circumference defined at an outer sealing surface of a high pressure seal. In other embodiments, fluid detected at the diagnostic port corresponds to a leak around a plunger at the inside diameter of the high pressure seal. Multiple diagnostic ports can be provided to allow separate determinations of leaks about the different portions of the high pressure seal. The embodiments may eliminate the need to disassemble the pump to determine the source of leaks. Thus the effort required to diagnose and repair the pump can be substantially reduced, and fewer misdiagnosed components are ordered or replaced.

A cylinder head gasket seals combustion chamber openings with two exterior active sealing layers and a central spacer layer. In web areas between adjacent combustion openings, each opening beginning of the active layers has a land, where a circumferential main stopper is formed with the central spacer layer between the lands. Each active layer further has longitudinal waves formed with the active layer which, when compressed, form a longitudinal support wave stopper(s) in the web areas. Each web area active layer further has a full bead(s) in contact with the central spacer layer. For each exterior layer, in one case, two beads come together to form a single central web area bead that separates two wave stoppers. In another case, the two outer bead portions come together upon entering the central web area while a single wave stopper is formed between the two inner bead portions.

A seal ring for an electrochemical processor does not slip or deflect laterally when pressed against a wafer surface. The seal ring may be on a rotor of the processor, with the seal ring having an outer wall joined to a tip arc through an end. The outer wall may be a straight wall. A relatively rigid support ring may be attached to the seal ring, to provide a more precise sealing dimension. Knife edge seal rings that slip or deflect laterally on the wafer surface may also be used. In these designs, the slipping is substantially uniform and consistent, resulting in improved performance.

Принадлежит: Kitz Corp

A shaft sealing device switches a sealing state and an unsealing state of a fluid, with high sealing performance maintained, because no abrasion accompanies movement of a sealing material or a sealing member, enabling feeding a fluid at a predetermined flow rate, and adjusts the expanding rate of the sealing material with the quantity of an external electric signal and accordingly adjusts the contact face pressure to enable controlling the amount of leakage of the fluid highly precisely, so that it can be used for all applications. The shaft sealing device includes a shaft sealing body formed of a macromolecular material and made expansible or contractible, or deformable, through external electrostimuli applied to a shaft sealing portion disposed in a device body, and flow passages disposed in the shaft sealing portion for feeding the fluid leaked due to the expansion or contraction, or the deformation, of the shaft sealing body.
