Hydrodynamic Seal
{{Unreferenced, date=June 2019, bot=noref (GreenC bot) A hydrodynamic seal is a type of mechanical seal. A hydrodynamic seals uses a dynamic rotor with grooves that act as a pump and create an air film that the opposing sealing surface will ride on. A hydrodynamic seal performs better than hydrostatic seals by providing greater film stiffness, lower leakage and lower lift off speeds. Hydrodynamic seals have a variety of applications in multiple industries. there are a large number of various groove designs that have been proposed and tested. Types of Hydrodynamic Grooves * Spiral Groove * Wave * V Grooves * U Grooves * Double V Grooves Seals (mechanical) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seal (mechanical)
A mechanical seal is a device that helps join systems and mechanisms 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. The seals are installed in pumps in a wide range of industries including chemicals, water supply, paper production, food processing and many other applications. A stationary seal may also be referred to as 'packing'. Seal types: *Induction sealing or cap sealing * Adhesive, sealant * Bodok seal, a specialized gas sealing washer for medical applications * Bonded seal, also known as Dowty seal or Dowty washer. A type of washer with integral gasket, widely used to provide a seal at the entry point of a screw or bolt * Bridgman seal, a piston sealing mechanism that creates a high pressure reservoir from a lower pressure source *Bung *Compression seal fitting *Diaphragm seal *Ferrofluidic se ...
