Nowadays, it is widely used in industry production, such as the separation of petroleum gas, adding hydrogen to the oil, air separation and refrigeration. The compressor is an important part in modernindustrial production, so it is necessary to master the design of compressor. The whole design is include the design of the overall structural, thermodynamic calculations, power calculations, the calculations of the mapping and structural components size. And the most important part is the thermodynamic calculation and the power calculation of compressor. According to medium, displacement, pressure of task-book, through the calculating getting related parameters of compressors. Such as series, columns, size of cylinder, shaft power. By dynamical computation can get the stress of piston type compression and the basic size, then getting the assembly drawing through the computer. KEYWARDS：natural gas，compressor, thermodynamic calculation, power calculation. 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc326965134 摘要(中文) PAGEREF _Toc326965134 \h I HYPERLINK \l _Toc326965135 摘要(英文) PAGEREF _Toc326965135 \h II HYPERLINK \l _Toc326965136 1绪论 PAGEREF _Toc326965136 \h 1 HYPERLINK \l _Toc326965137 1.1 概述 PAGEREF _Toc326965137 \h 1 HYPERLINK \l _Toc326965138 1.2 压缩机研究设计的意义 PAGEREF _Toc326965138 \h 1 HYPERLINK \l _Toc326965139 1.3 压缩机的基本结构、分类及工作原理 PAGEREF _Toc
