压缩机施工方案 .The installation of compressor
概述 Summary
上海赛科90万吨/年乙烯工程一标段有压缩机 3台。裂解气压缩机(C-2000)由凝器 式汽轮机驱动，为乙烯装置的心脏设备，安装中应严格按制造厂技术说明书和施工方案进 行。压缩组的主要特性见表4-1。
This rotary machinery installation plan is for the first bid of Shanghai SECCO 900,000 metric tons per year ethylene cracker project, which includes 82 sets rotary machines, 3 sets compressors, The cracked gas compressor (C-2000), which is the heart of the equipment in ethylene plant, and is driven by the condensed steam turbine, needs to be installed strictly according to technical specification and the installation plan. The key characters of this compressor are listed below (see table1-1).

通用要求 general requirements
压缩机组安装程序见图 4-% the installation procedure for the centrifugal compressor driven by steam turbine is listed in figure 4-1.
垫铁加工采用机械加工，垫铁的表面粗糙度不得低于 Ra5。
The shims should be fabricated by machine, the surface roughness should not lower than Ra5.
压缩机联轴器对中找正采用西德 Fixturlaser Shaft 200型激光对中仪，确保对中的质量
和速度。
The alignment of the compressor coupling will be executed with Fixturlaser Shaft 200 laser alignment instrument in order to ensure the quality and schedule.
.4管道预制及组装时，要考虑管道的应力释放。管道在与机器连接时使用百分表监控， 严禁强力对口。
The piping stress releasing should be considered during prefabrication and assembly. Dial indicators shall be used where the piping connects to the machines.
机器及零、部件吊装时应符合下列要求：
The following requirements shall be meet when lifting the machine and the parts.
——严禁将索具直接绑扎在加工面上，与机器接触的绑扎部位应垫上衬垫，或将索具 用软材料包裹；
