1 概述笔者近来有幸参加了巴基斯坦贾姆肖罗燃油电厂21万kw汽轮机安装测量工作。该热电厂采用哈尔滨汽轮机厂生产的N_(210)型汽轮机,该机为一次中间再热冷凝式汽轮机,全长约16米,单轴三缸,两排汽口结构,通过刚性联轴器直接带动发电机工作。它结构复杂,转子轴线长,故机组安装精度要求高。为缩短安装周期,在保证安装精度
1 Overview The author has recently been fortunate enough to have participated in the installation and measurement of 110,000 kw of steam turbines at Pakistan’s Jamsholuo oil-fired power plant. The thermal power plant adopts N_ (210) steam turbine produced by Harbin Turbine Plant, which is an intermediate reheat condensing steam turbine with a length of about 16 meters, single-shaft and triple-cylinder, two-row steam outlet structure and is directly driven by a rigid coupling Generator work. Its complex structure, rotor axis is long, so the installation of high precision unit requirements. To shorten the installation cycle, to ensure that the installation accuracy
