Patent attributes
A mechanical end face seal having an induction heated seal ring is provided to be used for sealing high-viscosity thermo-sensitive fluids in pressure containing rotating equipment. The different embodiments particularly provide a sealing member fixed to the housing, the sealing element is constructed using ferromagnetic materials. An induction coil attached to a power source is installed outside the housing, said induction coil is supplied with an alternating current producing a time dependent magnetic field that induces eddy currents in the aforementioned sealing member generating heat thus affecting the operating temperatures of the sealing member and hence the interface temperature to achieve greater sealing efficiency, longer seal life and faster equipment startup.
