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.
