Abstract
Systems, devices, and methods for continuously cooling a rotary shaft seal of a pressure vessel (e.g., of a furnace) are provided. A continuous flow of gas into the pressure vessel can be utilized to continuously cool the rotary shaft seal as the gas enters the pressure vessel. The rotary shaft can have a turbine wheel attached to it. The turbine wheel, when powered, can mechanically increase the natural convective gas flow inside a baffle tube of the furnace, effectively lengthening the usable, working homogenous zone of the furnace making overpressure heat treatment (OPHT) possible for longer canted cosine theta (CCT) magnets and “Race Track” coils.
Claims5
A method for continuously cooling a rotary shaft seal of a pressure vessel, the method comprising:
- providing a system comprising a rotary shaft, a turbine wheel attached to a first end of the rotary shaft, a T fitting having the rotary shaft disposed therethrough, a gas inlet connected to the T fitting, and a high pressure gland, the rotary shaft being disposed through the high pressure gland;
- attaching the rotary shaft seal to the rotary shaft, the rotary shaft seal being in direct physical contact with the rotary shaft;
- connecting the system to the pressure vessel;
- and
- operating the system to continuously cool the rotary shaft seal while the pressure vessel is in use,
- wherein the high pressure gland comprises a nut, and
- wherein the system is configured such that, upon failure of the rotary shaft seal, the nut of the high pressure gland is tightened to seal the rotary shaft.
