Project for repair of steam turbine PR-8,8-4,1 / 1,1 / 0,4 and its coupling to a new generator type T-12-2UZ


Overview

  • Employer:
    Svilocel EAD
  • Implementation period:
    October 2018 – December 2018

Object

Within the scope of Contract № D-990 / 24.10.2018 with – “SVILOTSEL” EAD, with subject “Project for repair of steam turbine PR-8,8-4,1 / 1,1 / 0,4 and its coupling to a new generator type T-12-2UZ”

Scope of the project

Subtask: Dynamic analysis of the shaft line of coupled rotors of turbine type PR-8,8-4,1 / 1,1 / 0,4 and of electric generator type TPS-12-2EUZ

Results

When performing the task, a dynamic analysis of the shaft line of coupled rotors of a turbine type PR-8,8-4,1 / 1,1 / 0,4 and of an electric generator type TPS-12-2EUZ was performed. In order to cover all possible variations in the behavior of the shaft line, five variants of the support system have been created, with recesses in the radial bearings. As a result of the analysis, the new critical frequencies during the rotation of the shaft line were determined.
