Variable-pitch multifinned seals (VPMS) have not hitherto found wide use in the steam turbines produced in Russia, although they are quite often used outside of Russia. In modernizing the existing and designing new steam turbines, rotor blades with a

The results from experiments for studying the effect of rotor rotation on the leakage through different types of seals are presented. It is shown from a comparative study of models involving a stalled rotor and rotor rotating with a 50 Hz frequency t

Energy losses caused by steam humidity are one of the main components of losses in the steps of nuclear power plants’ wet-steam turbines. The presence of moisture droplets in the flow part of the turbines also poses a serious danger due to erosion

During steam turbine operation in transient modes, contact in labyrinth seals is possible. To avoid such contact in the regular stepped labyrinth seals, specialists of the Ural Turbine Works upgraded the end seals during major repairs in several T-25

During the operation of steam turbines under transient conditions, due to different thermal expansion of the stator and rotor parts in the radial and axial directions, the clearances fixed in the course of assembling the seals of the flow path change
