核电汽轮机汽封径向间隙测量方法探讨

Discussion on Measuring Method of Nuclear Turbine Steam Seal Radial Clearance

文章以某公司引进国外百万等级核电半转速汽轮机(以下简称核电汽轮机)高中压模块为例,介绍了将改进后火电汽轮机径向间隙测量方法运用到核电汽轮机安装中,能够实现准确测量。对大型核电汽轮机新机安装和大修期间汽封径向间隙的测量有一定借鉴意义。

This article takes a company's overseas import 1000 MW nuclear power half rotation rate turbine high-mid module as sample to introduce the application of the improved radial clearance measurement method to installation of nuclear turbine,which achieve a acc rate measurement.that provides reference for steam seal radial clearance measurement of nuclear turbine installation and maintance.
