SEAL WITH ACTIVE ELECTROMAGNETIC ADJUSTMENT OF CLEARANCE Russian patent published in 2010 - IPC F16J15/00

Abstract RU 2386873 C1

FIELD: machine building.

SUBSTANCE: proposed seal comprises thrust disk arranged on rotor and axially moving ring arranged therein to make a sealing pair with axial clearance, system of active electromagnetic clearance adjustment made up of clearance pickup and electric magnet. The latter consists of magnetically conducting frame with winding and armature. The latter is connected, via amplifier, with clearance pickup. Armature is rigidly jointed to the ring of sealing pair. Housing space, behind sealing pair, communicates with gas leak line accommodating flow metre that allows transmitting feedback signal to system amplifier.

EFFECT: higher reliability.
