摘要:近年来,我国螺杆压编机制造行业有了较快的发展,下游应用领域需求也目渐广泛,各个应用领域对压缩机特殊化、专业化和个性化需求日渐突出。随着下游应用领城的逐渐拓展,国内的螺杆压缩机逐步由传统的空气动力压缩扩展到石油、天然气、化工、化肥、制碱等转球气体、工艺气体进行压缩,并逐步形成了差异化的工艺气用螺杆压缩机行业。在石油、化工、煤层气、天然气、制药以及其他稀有气体分离等行业对压编机市场需求日渐旺盛的情况下,国内的工艺气用螺杆压缩机的产销量都将保持稳步增长态势。

Abstract: In recent years, the screw compressor manufacturing industry has been developped rapidly in China. The demands in downstream applications have also become more widely, The needs for specialization , profession-al and personalized in every compressor application have become increasingly prominent, With the gradual ex-pension of downstream applications, the domestic compressors expanded from the air dynamic compression to special gas and process gas compression such as oil, natural gas, chemicals, fertilizer, and soda. Furthermore, it gradually forms a differentiated screw compressor industry for process gas, Under the demands of compressors in industries such as petroleum, chemical, coal bed methane , natural gas ,pharmaceutical and other rare gas separa-tion increasingly strong,the production and sales of domestic screw compressors for process gas will maintain steady growth.

域对压缩机的特殊化、专业化和个性化需求也日渐突出。在行业技术手段不断更新的驱动下,螺杆压缩机行业在传统应用领域基础上,也逐步由对工作介质清洁度要求较高的传统领域向对工作介质清活度要求相对较低的领域发展,逐步从最初的煤气压缩扩展到石油、天然气、化工、化肥、制碱等石化行业的特殊气体压缩,并进一步向制药、稀有气体分离等行业拓展,逐步形成了独具特色的、具有差异化的“专、特、精、新”等工艺气用螺杆压缩机行业。
工艺气用螺杆压缩机作为工艺压缩机的一个重要组成部分,在工艺气用压缩机强劲需求的推动下,近年来也持续保持快速发展态势。尤其是伴随着国
