Patent number: 11162591Abstract: A seal ring assembly for a rotor shaft includes a seal casing defining a radially inwardly directed channel. The seal ring is disposed in the radially inwardly directed channel of the seal casing. The seal ring is resiliently joined about the shaft to form a seal, and the seal ring comprises an electrically insulating or dissipative material or a non-metallic material.Type: GrantFiled: March 10, 2016Date of Patent: November 2, 2021Assignee: GENERAL ELECTRIC COMPANYInventors: Matthew Robert Martin, James Jonathan Grant, Anthony James George, Eric Steven Buskirk, Daniel James Fitzmorris

Patent number: 10208862Abstract: A seal ring assembly includes a first seal ring axially disposed from a second seal ring. The first seal ring has an axial face opposing an axial face of the second seal ring. A radial oil channel is defined between the two axial faces. Both seal rings have a tapered surface configured to contact a spring. The spring biases the seal rings away from each other via the tapered surface. Both seal rings are disposed in a radially inwardly directed channel. At least one of the seal rings have a plurality of protrusions that extend beyond the axial face. The protrusions are configured to create a passageway to allow oil to flow through the passageway and to allow at least one of the seal rings to move into a desired position by reducing static friction between the axial faces.Type: GrantFiled: January 13, 2015Date of Patent: February 19, 2019Assignee: General Electric CompanyInventors: Daniel James Fitzmorris, Anthony James George, Anthony Salvatore Arrao, Anand Shankar Tanavde, Matthew Robert Martin

Patent number: 8564237Abstract: In an embodiment, a system includes: a casing for surrounding at least a portion of a rotor, and enclosing a volume of a cooling gas thereabout, the casing including a plurality of static seals; an end housing at each end of the casing, each end housing including a seal system through which the rotor extends, wherein a portion of cooling gas escapes from the casing to at least one seal area; and a source of cooling gas fluidly coupled to the casing by a cooling gas regulator. The system may further include: a scavenging system coupled to each end housing for removing a gas mixture therefrom including a portion of escaping cooling gas; a sensor for determining a purity of the cooling gas in the casing; and a static seal leak detector that generates an alarm indicative of a leak in at least one of the plurality of static seals.Type: GrantFiled: January 5, 2011Date of Patent: October 22, 2013Assignee: General Electric CompanyInventors: Vinodh Kumar Bandaru, Jeffrey James Andritz, James Daniel Antalek, Krishna Swamy Cherukuri, Daniel James Fitzmorris, Anthony James George, Nicola Piccirillo, Sudhanshu Rai

Publication number: 20110072640Abstract: A method for modifying a sealing system of a hydrogen-cooled generator includes coupling to a sealing device of the generator a contacting seal comprising a plurality of non-metallic bristles projecting from an aluminum body with tips of the bristles engaging a rotor of the generator. Another method includes removing a portion of a non-contacting seal, providing a replacement sealing device comprising an aluminum body and a plurality of non-metallic bristles projecting therefrom, and replacing the removed portion of the non-contacting seal by coupling the aluminum body to the non-contacting seal such that tips of the bristles contact the rotor. Another method includes removing an original sealing device, providing a replacement sealing device comprising an aluminum body and a plurality of non-metallic bristles projecting therefrom, and inserting the replacement sealing device into the generator such that tips of the bristles contact a rotor of the generator.Type: ApplicationFiled: December 3, 2010Publication date: March 31, 2011Applicant: GENERAL ELECTRIC COMPANYInventors: Eric John Ruggiero, Nitin Bhate, Daniel James Fitzmorris, Anthony James George
