Best Mech. seal solution for Thermic Oil, 300¦C
(OP)
Hello guys,
I would like you to help me to choose the best solution for this application:
Fluid: Thermic Oil
Temperature: 300ºC
Stuffing box pressure: 6 bar
RPM: 1800
shaft: 55mm
Which would be the best lubrication API PLAN?

External seal (single cartridge) or internal seal?
If we use internal seal we should include the connections in the stuffing box in some way but with a cartridge we already have it. Is it correct?
The quench fluid can be water?
As the pressure in the quench would be less than 1 bar (or so) the natural leakage would be from the product to the quench fluid. But without using a reservoir, how is it posible to know when the seal fails?

I plan 02/52 but this can be costly.
Speak to your local seal representative.

If I use a main water line for the quench, I should increase the temperature before going into the cartridge, right?

What do you think? Otherwise, another alternative?

Thank you for your help in advanced.
Could you explain to me the potencial problems that can happen if using water?
I mean, the liquid flash off when entering the quenching area and becomes steam.
What is the main difference between using steam or water that becomes steam when entering?
Thank you for your help.

Another thing. Is The thermic Oil to that temperature good enough to lubricate the faces?
RE: Best Mech. seal solution for Thermic Oil, 300¦C
Typically, the drain is freely pipied to atmosphere. If you can't tolerate any leakage to atmosphere, you can route leakage to a collection device, labeled API Plan 65A or B; not to be confused with Plan 75 which is for dual seals. If you want to go lower tech, you can run a Plan 66A or B, which involves an additional port between the seal faces and throttle bushing where a pressure sensing device is mounted (gauge or transmitter). The area between the sensing port and quench area is either separated by a bushing (Plan 66A) or an orifice fitting is included in the connection (Plan 66B). The purpose of the last two plans is to provide restriction for leakage of the primary seal enough so that pressure will be detectable in order to provide an indication of increased primary seal leakage.
These are just some suggestions. Whoever is your preferred seal vendor should be able to provide you with some guidance as well.
