Thermal calculation and dynamical computation is basic of compressor design’ calculation, is also an important woke, according to medium, displacement, pressure of task-book, by calculating getting related parameters of compressors, such as levels, columns, size of cylinder, shaft power, by dynamical computation getting stressed status of a piston type compression, due to reduce the vibration is very important. heat calculation and dynamical computation of the piston type compressor, which is providing design data. The calculations reflect exactly the design level of the compressor. Researching works is in order to the compressor have better mechanical properties, improve the efficiency and reduce energy consumption, prolong the machine the useful life. Through dynamical computation correction the size of crew, members, to improve the technical failure of the compressor, As shooting of low displacement, the cylinder, the piston, piston ring severity serious abrasion, so that increasing the related clearance, leakage rate, influence the displacement. Due to some problem of not normal noise improve. Eventually, work out this paragraph
