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 limited contact-sealing action that creates the seal.
Tandem seal with intermediate labyrinth; Double opposed seal - Used when the processed gas is abrasive (like hydrogen) and lower pressure designs. All designs use buffering with "dry" gas, supplied through control and purification systems. All Dry Gas Seals need additional protection from the process and the bearing lubrication sides of the seal
The seal provided by a threaded pipe joint depends upon multiple factors: the labyrinth seal created by the threads; a positive seal between the threads created by thread deformation when they are tightened to the proper torque; and sometimes on the presence of a sealing coating, such as thread seal tape or a liquid or paste pipe sealant such ...
A seal is a device or material that helps join systems, mechanisms or other materials together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets .
A static hydraulic seal is located in a groove and sees no movement - only sealing within its confined space, acting like a gasket. To achieve this the gasket should be under pressure. The pressure is applied by tightening of the bolts. Examples of static seals include O-rings, flange seals, and cover seals. Dynamic
The video was captured near Puerto Ayora, a tropical beach town that also happens to be a mere 10 minute walk from the Charles Darwin Research Center.
The Smithsonian’s National Zoo is celebrating the arrival of an adorable new baby.
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]
