The first dry gas seal for a compressor was patented by Kaydon Ring & Seal in 1951 when it was known as Koppers Corporation. Field applications of dry gas seal designs were completed in 1952. The original patent was for Kaydon's "Tapered Ramp" lift geometry, a constant diameter / variable depth dynamic lift design. From that first dry gas seal ...
This seal will be used with a dry running containment seal and the leakage past the inner seal will be piped to a vapor recovery system. [4] The other new seal type introduced in 2nd Edition was the dry running gas seal used in Arrangement 3. This seal is designed to run on a gas barrier fluid such as nitrogen. [4]
Inflatable seals can be used for numerous applications with difficult sealing issues. Labyrinth seal A seal which creates a tortuous path for the liquid to flow through; Lid (container) Rotating face mechanical seal; Face seal; Plug; Radial shaft seal; Trap (plumbing) (siphon trap) Stuffing box (mechanical packing) Wiper seal; Dry gas seal
Indeed, many gas turbine engine seals leak by design. [4] Labyrinth seals are also found on pistons, which use them to store oil and seal against high pressure during compression and power strokes, as well as on non-rotating shafts. In these applications, it is the long and difficult path and the formation of controlled fluid vortices plus some ...
In mechanical engineering, an end-face mechanical seal (often shortened to mechanical seal) is a type of seal used in rotating equipment, such as pumps, mixers, blowers, and compressors. When a pump operates, the liquid could leak out of the pump between the rotating shaft and the stationary pump casing. Since the shaft rotates, preventing this ...
A dry-seal Wiggins-type gas holder. Dry-seal gas holders have a static cylindrical shell, within which a piston rises and falls. As it moves, a grease seal, tar/oil seal or a sealing membrane which is rolled out and in from the piston keeps the gas from escaping.
