Abstract
Disclosed is a seal for a turbomachine including at least one fixed component located proximate to a rotating component of the turbomachine defining a clearance therebetween. At least one magnet is located at the at least one fixed component. The at least one magnet is, when activated, capable of moving the at least one fixed component thereby adjusting the clearance between the fixed component and the rotating component. Further disclosed is a turbomachine utilizing the seal and a method for adjusting a position of at least one fixed component of a turbomachine.
Claims20
A seal for a turbomachine comprising:
- at least one fixed component disposed proximate to a rotating component of the turbomachine defining a radial clearance therebetween;
- and
- at least one magnet disposed at the at least one fixed component, the at least one magnet, when activated, capable of moving the at least one fixed component thereby adjusting the radial clearance between the at least one fixed component and the rotating component.
A turbomachine comprising:
- a casing;
- at least one rotating component disposed in the casing, the at least one rotating component rotatable about a central axis of the turbomachine;
- at least one fixed component disposed in the casing to define a radial clearance between the at least one rotating component and the at least one fixed component;
- and
- at least one magnet disposed such that when the at least one magnet is activated, the radial clearance between the at least one rotating component and the at least one fixed component is adjusted.
A method for adjusting a position of at least one fixed component of a turbomachine comprising:
- disposing at least one magnet proximate to the at least one fixed component having a radial clearance between the at least one fixed component and a rotating component;
- activating the at least one magnet thereby creating a magnetic field in magnetic communication with the at least one fixed component;
- and
- moving the at least one fixed component via the magnetic field thereby adjusting the radial clearance between the at least one fixed component and the radial component.
