摘 要
壓縮機(jī)是現(xiàn)代工業(yè)上使用量大，范圍廣的一種通用機(jī)械。按照工作原理區(qū)分為兩大類，即速度型和容積型，而活塞式壓縮機(jī)是屬于容積型壓縮機(jī)的其中一種。它是利用活塞在氣缸中運(yùn)動(dòng)對氣體進(jìn)行擠壓，使氣體壓力提高。它與其它種類的壓縮機(jī)相比，具有壓力范圍最廣、效率高、適應(yīng)性強(qiáng)等優(yōu)點(diǎn)。
在活塞式壓縮機(jī)設(shè)計(jì)計(jì)算中最根本也是最重要的是熱力計(jì)算和動(dòng)力計(jì)算。根據(jù)任務(wù)書中提供的介質(zhì)、氣量、壓力等參數(shù)要求，經(jīng)過熱力計(jì)算計(jì)算得到相關(guān)的參數(shù)，如級數(shù)、壓力比、軸功率、氣缸直徑等，經(jīng)過動(dòng)力計(jì)算得到活塞式壓縮機(jī)的受力情況。活塞式壓縮機(jī)的熱力計(jì)算和動(dòng)力計(jì)算的結(jié)果將為各部件圖形以及基礎(chǔ)設(shè)計(jì)提供原始數(shù)據(jù)，計(jì)算結(jié)果的精度將體現(xiàn)活塞式壓縮機(jī)的設(shè)計(jì)水平。

Abstract
Compressor is the modern industrialusage,widerangeofakindofgeneralmachinery .According to the principle of work is divided into two categories, namely the speed andvolume .The piston compressor is belongs to one of the volume type compressor. It is the use of the piston in the cylinder movement to extrusion of gas, increase the gas pressure .It compared with other types of compressor, pressure range and the advantages of high efficiency, strong adaptability .
In the piston compressor design and calculation is the most fundamental and most important thermodynamic calculation and dynamic calculation .According to the specification provided in the parameters such as medium, gas, pressure requirements .Through thermodynamic calculation to calculate the related parameters, such as series, pressure ratio, shaft power, cylinder diameter, etc .Through the dynamic force of the piston compressor is calculated .Piston compressor thermodynamic calculation and dynamic calculation results will provide original parts graphics and basic design data .The precision of the calculation result will reflect the design level of piston compressor.
Keywords: Piston Compressor; Thermodynamic Calculation; Dynamic Calculation ; Cylinder ...
