Dynamic Response Analysis of Balance Drum Labyrinth Seal Groove Geometries Optimized for Minimum Leakage1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Annular labyrinth seals often have a destabilizing effect on pump rotordynamics due to the large cross-coupled forces generated when the fluid is squeezed by an oscillating rotor. In this study, several novel groove ...
On the Dynamic Properties of Pump Liquid Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rotordynamic instability due to fluid flow in seals is a well known phenomenon that can occur in pumps as well as in steam turbines and air compressors. While analysis methods using bulkflow equations are computationally ...
