石油、化工用轴流和离心压缩机及压缩机 透平机组

[中文适用范围]： This standard specifies minimum requirements and gives recommendations for axial compressors, single-shaft and integrally geared process centrifugal compressors, and expander-compressors for special-purpose applications that handle gas or process air in the petroleum, chemical, and gas industries. This part of API 617 specifies general requirements applicable to all such machines. API 617 does not apply to the following: — fans (these are covered by API 673) or blowers that develop less than 34 kPa (5 psi) pressure rise above atmospheric pressure; — integrally geared centrifugal plant and instrument air compressors, which are covered by API 672; — axial inflow expanders, such as hot gas expanders. This part of API 617 contains information pertinent to all equipment covered by the other parts of this document. It shall be used in conjunction with the following parts, as applicable to the specific equipment covered: — Part 2—Nonintegrally Geared Centrifugal and Axial Compressors; — Part 3—Integrally Geared Centrifugal Compressors; — Part 4—Expander-compressors. [外文原描述]： Covers the minimum requirements for centrifugal compressors used in petroleum, chemical, and gas industry services that handle air or gas, including process gear mounted. Does not apply to fans or blowers that develop less than 34 kPa (5 psi) pressure rise above atmospheric pressure; these are covered by API Standard 673. This standard also does not apply to packaged, integrally-geared centrifugal air compressors, which are covered by API Standard 672.
