Keeping bearings free from contamination on process steam turbines provides a unique challenge. Typically carbon ring seals are fitted to the turbine contain the steam. These seals wear with time allowing high temperature, high velocity steam to travel down the turbine shaft directly on to the bearing seals.
AESSEAL® have developed bearing protectors that are designed specifically for this tough application that provide the protection needed to ensure the bearing lubrication remains free of contamination. The designs feature:
- High temperature shaft seals
- A steam deflector / flinger
- Extra clearance to manage thermal expansion
- Aflas® ‘O’ rings
