电力部电力建设总局于1980年6月在南通天生港电厂召开了汽轮机本体安装新工艺技术交流会。会议交流、座谈了激光、光学准直仪找正汽轮机本体的新工艺、新技术,上海光学仪器二厂、上海科技大学的代表向会议介绍了有关仪器设备的研制情况。所谓激光准直技术,就是利用激光器在空间建立一条基准直线,用它来确定轴承座、汽缸、隔板、汽封等相对位置,以达到二转子之间的同心及通流部分的正确间隙。自1974年以来,上海电建公司一处、
Electric Power Construction Bureau in June 1980 in Nantong Tianshenggang Power Plant held a steam turbine installation of new technology exchange. Conference exchange, discussion of laser, optical collimator to find the new technology of steam turbine ontology, new technology, Shanghai Optical Instrument Factory, Shanghai University of Science and Technology on behalf of the conference introduced the development of equipment. The so-called laser alignment technology, is the use of lasers in the space to establish a reference line, use it to determine the bearing seat, cylinder, diaphragm, seal and other relative positions in order to achieve the two rotors concentric and flow through the correct part of the gap. Since 1974, Shanghai Electric Construction Company a,
