<p>The invention relates to power engineering, in particular to a method for restoring a radial clearance between the stator and rotor parts of a turbogenerating set during reparation of the flow section thereof. The inventive method for restoring a radial clearance between the stator and rotor parts of a turbogenerating set, consists in mounting a temporary shroud, which is made of a sheet material and the thickness which corresponds to a clearance size, on the rotor blades of a demounted rotor, in fixing a protective cover made of a composite material to said shroud, in applying a polymerisable epoxy resin material to the internal surface of the stator and to the protective cover of the blade shroud, in mounting the rotor in the stator and, said resin being polymerized, in removing the shroud and excess of resin, projected in the axial direction during said mounting, from the rotor. Said invention makes it possible to reduce labour input for the turbogenerating set maintenance and repair.</p> |
