METHOD OF SEALING SHAFT OF ROTOR MACHINE Russian patent published in 1995 - IPC

Abstract RU 2030661 C1

FIELD: mechanical engineering. SUBSTANCE: ring rotating flow of sealing fluid undergoes outer hydrothermal effects and negative density gradient is created along the ring radius. If kinematical viscosity of fluid does not exceed 5·10^-6 m²/s the value of the density gradient is maintained at a level defined by a relationship available in the invention description. EFFECT: simplified method. 4 dwg
