摘要

在汽轮机大修过程中,通流间隙测量是一项非常重要的工作,其测量准确性是保证机组能否安全经济运行的关键。本文主要介绍汽轮机低压缸通过新工艺消除缸体变形对通流间隙测量的影响,实现通流间隙的准确测量。
        In the course of steam turbine overhaul, the measurement of flow clearance is a very important work,and its measurement accuracy is the key to ensure the safe and economical operation of the unit. In this paper, a new process is introduced to eliminate the influence of cylinder block deformation on the measurement of flow clearance, and the accurate measurement of flow clearance is realized.
