一、前言本文简要地介绍一种用激光准直仪安装国产N125汽轮机的情况。几年来,我们陆续在国产中小型汽轮机安装工艺上作了相当范围的应用,革除了一直沿用的拉钢丝、假轴找正法的陈旧工艺,在一定程度上提高了安装精度并缩减了工期。所以希望通过各有关方面的支持,来进一步普及、改进和提高,以使激光准直技术在更多的汽轮发电机组安装工程或其它工程上能扩大应用。随着汽轮机单机容量的增大,汽轮机汽缸和轴承座数量逐渐增多,其间距加长,机组外
I. Preface This article briefly introduces a laser collimator installed domestic N125 turbine situation. Over the past few years, we have made quite a range of applications in the domestic small and medium-sized steam turbine installation process, to get rid of the old technology of pulling steel wire and fake shaft alignment method, which has improved the installation precision and reduced the construction period to a certain extent. Therefore, I hope that through the support of all parties involved, further popularization, improvement and enhancement will be made so that the laser collimation technology can be expanded for more turbine installation projects or other projects. With the increase of steam turbine unit capacity, the number of steam turbine cylinder and bearing seat gradually increases, and the spacing between them is longer,
