Discussion Overview
The discussion revolves around alternatives to mercury seals for high RPM generators, specifically in the context of establishing contact between the rotor and stator at speeds of 25,000 to 30,000 RPM. The focus includes potential sealing methods and electrical connections.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant inquires about alternatives to mercury seals for high RPM generator designs.
- Another participant suggests considering carbon seals as a potential alternative.
- A different participant mentions magnetic oil rotary shaft seals as a solution for sealing a rotating shaft, particularly for applications involving vacuum.
- There is a mention of mercury wetted slip rings from Mercotac for passing electrical connections to the shaft.
- A participant references FLOWSERVE's use of mercury seals in their Byron-Jackson Type H motors for deep water well applications, suggesting contacting them for more information.
Areas of Agreement / Disagreement
Participants present multiple competing views on alternatives to mercury seals, indicating that the discussion remains unresolved with no consensus on a single solution.
Contextual Notes
Some suggestions depend on specific applications, such as vacuum sealing or electrical connections, which may not be universally applicable to all high RPM generator designs.
