往复式天然气压缩机成橇建造技术的研究

Research on Assembly Process of Reciprocating Natural Gas Compressor

随着海上油气田尤其是气田开发的迅速发展,对天然气压缩机的需求与日俱增。成橇设计和制造的优劣对天然气压缩机运行起到至关重要的作用。目前国内厂家普遍通过与国外相关厂家合作进行压缩机的成橇设计和建造,但压缩机主机机组和电机等设备主要依靠国外进口。基于国内外主流压缩机成橇厂家的现状和JZ25-1SⅡ天然气压缩机橇项目,详细阐述了成橇工艺中底座预制和关键装配工艺等技术重点和难点,并对带二层辅橇的压缩机橇的整体和分体成橇工艺的优劣进行了探讨。

With the rapid development of offshore oil and gas fields,especially the development of gas fields,the demand for natural gas compressors is increasing.The advantages and disadvantages of the assembly design and manufacturing plays a vital role in the normal operation of natural gas compressors.At present,domestic manufacturers generally cooperate with foreign manufacturers to design and construct the sled of compressor,but compressor main engine and motor mainly depend on imports.Based on the current situation of domestic and foreign mainstream compressor manufacturers and JZ25-1SⅡnatural gas compressor project,the key and difficult points of the base prefabrication and key assembly process are described in detail.In addition,the advantages and disadvantages of the whole and the split assembly processes for the compressor with two-layer operating platform are discussed.
