Stepped Labyrinth Seal an overview | .

A step can be incorporated in a labyrinth seal design in order to prevent carryover of kinetic energy from occurring as illustrated in Fig. 14.44. This provides improved sealing characteristics in comparison to straight labyrinth seals. However, radial space must be available in machines where sealing is required to accommodate a stepped seal. In addition, axial pressure gradients acting on

Labyrinth Seal an overview | ScienceDirect Topics

Labyrinth seals that do not contact the shaft depend on a tortuous interface, fluid surface tension, and a pumplike design to prevent leakage. Most PTFE seals are supported by metal springs or elastomeric rings to assure good shaft contact. Used by itself, PTFE, even when compounded with fillers, may creep under load and reduce sealing force. PTFE seals may have surface features that, with

LABYRINTH SEAL LEAKAGE EQUATION

For labyrinth seals, which are widely used, the energy dissipation is achieved by a series of constrictions and cavities. When the fluid flows through the constriction (under each tooth), a part of the pressure head is converted into kinetic energy, which is dissipated through small scale turbulenceviscosity interaction in the cavity that follows. Therefore, a leakage flow rate prediction
