Oil Coking limits
Oil Coking limits
(OP)
We use magnetic face seals in place of lip seals on a wide variety of applications, usually on pumps but alos gearboxes and other equipment. The only factor limiting the speed of operation is the heat generated and this cokes (carbonises)the oil.
I am looking for information on what the coking temperatures would be for a range of proprietry oils. The oil companies do not seems to give this information on their data sheets and a brief trawl of the internet failed to get anything meaningful.
Does anyone have any pointers they could give me so I can find the coking temperatures, or am being too simplistic and getting into a very complicated area?

As for your seals - dependant on what the application is labrinth seals (no contact) are use in marine steam turbines for high speed applications & can be successfully adapted for many other "problem" areas.
I'eve used them for rod seals on pneumatic cylnders on plastic thermo forming machines where standard nitrile & viton seals have failed.
