The double-tooth turbulence steam seal is developed on the basis of the conventional labyrinth steam seal. Without altering the external shape or dimensions of the original labyrinth steam seal, it incorporates turbulence steam inlets and turbulence teeth into the labyrinth cavity. Through the turbulence-inducing effect of these additional features, the kinetic energy of the steam passing through the labyrinth is more effectively converted into thermal energy, thereby reducing steam leakage.

Advantages:

• Absolute safety, with a design philosophy of identical materials, same external dimensions, and different internal structures, ensuring the stability and reliability of the original labyrinth-style steam seal.
• High efficiency and energy savings, improving sealing efficiency by more than 5%, resulting in substantial energy conservation.
• The double-tooth turbulence steam seal forms an integrated unit, offering safe and reliable operation.
• Effectively prevents steam leakage, avoiding its entry into the interior of the bearing housing and thereby causingoil emulsification.
• The double-tooth turbulence structure eliminates circumferential clearance-induced vibrations. Even with uneven clearance, this steam seal configuration prevents steam-flow excitation, effectively protecting both the shaft and the seal teeth, thereby enhancing the safety performance of the unit.

Application Range
Various types of steam turbine shaft end seals and balance piston seals.
