Abstract
The basics of sealing and its connection with the dynamics of centrifugal machines are described. Modeling, calculation and construction of packing and mechanical seals are presented. Designs, models and calculation methods of non-contact seals, as well as analysis of their infl uence on the vibration state of centrifugal machine rotors, are considered. Directions for improving seals are proposed. The general principles of the construction of complex sealing systems are presented.
