Regarding Mechanical Seal Basics
(OP)
I've never seen an answer to the question regarding why one face must rotate and why the other is stationary. I've always believed the best explaination as to why one face rotates is to generate a hydrodynamic seal by both viscous shearing and heat generation to "flash" off visible leakage. Thoughts?





RE: Regarding Mechanical Seal Basics
So the rotating face rotates with the shaft at whatever speed it is doing. A fluid film is formed between the faces and heat is generated at the seal faces. This is why we have different piping plans to disapate the heat.
If the shaft was static then you do not need a mechancial seal you can have a housing with an Oring seal.
i trust that this is clear for you.
