Reciprocating piston compressor is a volume compressor, which is to increase pressure to discharge fluid by piston. Thermal and dynamic compressor design is the basic and most important one, according to users with the content, gas, pressure and other parameters, calculated after the compressor related pa-rameters, such as class, number, size cylinder, shaft power, and so on. After driving force calculated piston compressor of the force. It is very important to eliminate the vibration by accurate analysis of the force units. During alterative working conditions, it is need to meet the movement requirement for original design of flywheel rapidly. Thermodynamic and dynamic calculations of Piston compressor provide original data for unit graphics and basic design, the calculated results reflect the grade of the compressor design, and the compressor is a study of the topic.
