The dynamic analysis to the itinerary and volume of piston compressor s cylinder by using PRO/E Mechanism;

The paper aims at the problem of movement interfere check for crankguide in piston compressor design,puts forward the method to carry out motion simulation for piston compressor using the Pro/MECHANISM module of Pro/E,and introduces the actual operation process.

It gives the method of setting up the parameterized standard part database by using the family table function of Pro/E,and introduces the actual operation process of setting up the standard part database for piston compressor cylinder flange.

Study of pressure between stages calculational methods for pressure between stages of reciprocating compressor under variable operating condition;

The overall rule and performance of water-injection internal cooling in the reciprocating compressors was studied when crank angle equals to 180 degrees using the mathematical models in the reference~([1]).

Proceed from thermody namic calculation of the reciprocating compressor,analyze the influence of intake and discharge pressure on reciprocating compressor′s discharge volume and power consuming.

0,and set up a parametric design system of the piston-compressor parts.

The motion emulate of the piston-compressor guarantees the rationality and the dependability of the compressor structure from the athletic angle.

By comparing crankle-framework with the crankshaft-framework of piston-compressor,the article proposes specific theory analysis about crankle and crankshaft under pressure,summarizing the superiority of crankle,providing theory evidence for crankle instead of crankshaft and giving the proof of improving performance of crankle.
