For Steam Turbine Applications
Process steam turbines present a unique challenge for bearing protection. As the carbon rings containing the steam wear, high temperature / high velocity steam travels down the shaft directly at the bearing seal.
Standard OEM labyrinth seals have proven to be ineffective at preventing steam ingress. AESSEAL® has developed LabTecta® designs specifically designed for steam turbine applications.
Features:
-
High temperature static shaft seal
-
Steam deflector / Flinger
-
Aflas® ‘O’ rings as standard
-
Internal shut-off valve
-
Extra clearances for thermal expansion
For smaller steam turbines, the LabTecta®ST design provides excellent protection in a compact package. For larger steam turbines, the LabTecta®ST-STAX provides easy installation with the capability to accommodate large axial shaft movement.
Standard designs are available for common steam turbines models like the Elliott® YR series. Specific designs can be manufactured at no additional charge.
