Hydrodynamic seal
Encyclopedia
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 lover lift off speeds. Hydrodynamic seals have a verity of applications in multiple industries. there are a large number of various groove designs that have been proposed and tested.
