Повышение надежности эксплуатации турбинного оборудования за счет использования системы охлаждения высокотемпературных шпилек корпусов цилиндров

Повышение надежности эксплуатации турбинного оборудования за счет использования системы охлаждения высокотемпературных шпилек корпусов цилиндров

Abstract

The article deals with improving the reliability of steam and gas turbines, by minimizing the effect of relaxation of thermal stresses on the studs flanged connections casing for steam and gas turbines. To improve the durability of a reliable seal of the connector of the high pressure cylinder and leaks through the flange connector of the proposed cooling system high temperature studs. Considered an example of a specific implementation of the algorithm of thermal calculation in relation to the cooling device pins of turbine ST -60-130.

В статье рассматриваются вопросы повышения надежности паровых и газовых турбин за счет минимизации эффекта релаксации тепловых напряжений, возникающих на шпильках фланцевых соединений корпуса паровых и газовых турбин. Для повышения долговечности надежного уплотнения разъема цилиндра высокого давления (ЦВД) и устранения утечек через фланцы разъема предложена система охлаждения высокотемпературных шпилек. Рассмотрен пример конкретной реализации алгоритма теплового расчета применительно к охлаждающему устройству шпилек турбины ПТ-60-130.
