摘 要
活塞式壓縮機是一種容積式壓縮機，用來提高氣體壓力和傳送氣體，目前廣泛用于工業(yè)生產(chǎn)中，例如：石油、化工、冶金、輕功、紡織、及采礦等。因此，氣體壓縮機是近代工業(yè)生產(chǎn)中不可缺少的通用機械。結(jié)合所學(xué)過的中小型壓縮機，了解其基本結(jié)構(gòu)及其工作原理，重點掌握其結(jié)構(gòu)設(shè)計學(xué)會所含零部件的結(jié)構(gòu)設(shè)計方法及其強度校核方法，在設(shè)計過程中，理論聯(lián)系實際，最終了解設(shè)計一個機械設(shè)備基本思想和方法。
W型風(fēng)冷微型活塞式壓縮機主要用于工業(yè)中氣體壓縮，雖然其結(jié)構(gòu)有別于其他壓縮機，但它們原理相似。因此可以根據(jù)已知的壓縮機類型，通過互相比較進(jìn)而進(jìn)行設(shè)計。
整個設(shè)計過程包括整體總體結(jié)構(gòu)設(shè)計、熱力學(xué)的計算、初定相關(guān)零部件結(jié)構(gòu)尺寸，然后借助CAXA等繪圖軟件，選定軸承等標(biāo)準(zhǔn)件，應(yīng)用強度理論對其進(jìn)行必要的強度校核以滿足實際的需要，最后確定壓縮機的輔助設(shè)備。

Abstract
The piston compressor is a positive displacement compressor used to increase the gas pressure and gas transmission, now widely used in industrial production, such as: petroleum, chemical, metallurgy, dodge, textile, and mining. Therefore, the gas compressor is indispensable in modern industrial production of general machinery. Combined with the small and medium-sized compressor, we understand the basic structure and how it works, focus on mastering the Society of structural design components contained in the structural design method and its strength check method, theory with practice in the design process, the final Learn basic ideas and methods of the design of a mechanical device.
W-type air-cooled micro-piston compressor is mainly used for industry, gas compression, although its structure is different from other compressor, but they are similar in principle. Therefore it can be known according to the type of the compressor, by mutual comparison Further design.
Throughout the design process, including overall design of the overall structure, thermodynamic calculations, an initial component structure size CAXA and other graphics software, and then with the selected bearings and other standard parts, application strength theory be necessary strength check to meet the actual need to finalize the compressor auxiliary equipment.
Keywords: Piston compressor; Strength check; Stroke volume; Dynamic calculation
