Abstract
A seal system for controlling dampening in a journal bearing system. The seal system includes a plurality of seals that include a first seal and a second seal. The first seal is operable to provide a first range of dampening compliance under a first range of journal bearing operating conditions. The second seal is operable to provide a second range of dampening compliance under a second range of journal bearing operating conditions. The first range of dampening compliance is different from the second range of dampening compliance.

A seal system for controlling vibration dampening in a journal bearing system, the seal system comprising:
- a plurality of seals comprising a first seal and a second seal;
- wherein the first seal is operable to provide a first range of vibration dampening compliance under a first range of journal bearing operating conditions;
- wherein the second seal is operable to provide a second range of vibration dampening compliance under a second range of journal bearing operating conditions;
- and
- wherein the first range of vibration dampening compliance is different from the second range of vibration dampening compliance.
A seal system for controlling vibration dampening in a journal bearing system, the seal system comprising:
- a plurality of seals comprising a first seal and a second seal;
- wherein the first seal and the second seal are between a first component and a second component of the journal bearing system;
- wherein the first seal is operable to provide a first range of vibration dampening compliance under a first range of journal bearing operating conditions;
- wherein the second seal is operable to provide a second range of vibration dampening compliance under a second range of journal bearing operating conditions;
- and
- wherein the first range of vibration dampening compliance is different from the second range of vibration dampening compliance.
A method of forming a seal system for controlling vibration dampening in a journal bearing system, the method comprising:
- forming a plurality of seals comprising a first seal and a second seal;
- wherein forming the first seal comprises configuring the first seal to provide a first range of vibration dampening compliance under a first range of journal bearing operating conditions;
- wherein forming the second seal comprises configuring the second seal to provide a second range of vibration dampening compliance under a second range of journal bearing operating conditions;
- and
- wherein the first range of vibration dampening compliance is different from the second range of vibration dampening compliance.
