本文介绍了空分设备应用到的压缩机的各种机组类型的特点及其应用场合,其中详细介绍了离心式压缩机配套空压机、增压机、产品压缩机及仪表空气压缩机的类型和国内外供货商及其特点,简要阐述了空分设备典型一拖二压缩机组常见方案,最后指出了选择压缩机组对投资和运行费用二者的矛盾性和重要性。 This paper introduces the characteristics of various types of compressors used in air separation plants and their applications. The types of centrifugal compressors supporting air compressors, superchargers, product compressors and instrumentation air compressors are described in detail. And domestic and foreign suppliers and their characteristics, a brief description of the typical one-to-two compressor unit air separation plant program, and finally pointed out that the choice of compressor unit on the investment and operating costs of both the contradiction and importance.
