Control Leakage, Create Damping
Bearings Plus offers a variety of damper seal technologies to ensure reliable rotordynamic operation for high-performance applications.
These sealing technologies not only control leakage but also generate damping to improve machine stability. This damping capability enables superior subsynchronous damping performance of rotating systems at high operating speeds.
- High-pressure centrifugal compressors
- High-speed integrally geared compressors
- Steam turbines
Honeycomb damper seals feature precisely machined, tightly packed individual chambers to create pressure drop and prevent gas swirl.
Hole Pattern Seals
Hole pattern seals work on a principle similar to the honeycomb seal. Typically, they allow slightly more leakage but can handle higher pressures.
