文档介绍：螺杆压缩机的设计与运动仿真
摘要
双螺杆压缩机是一种比较新颖的压缩机,因其可靠性高、操作维修方便、动力平衡性好、适应性强等优点,而广泛地应用于矿山、建筑、化工、冶金、动力、机械、制冷等工业部门。双螺杆压缩机已经超过所有工业压缩机的50 %,其市场份额超过80 %,今后其市场份额还将继续扩大。可见,研究双螺杆压缩机具有十分重要的意义。本课题主要是设计通用的喷油双螺杆空气压缩机,采用单边不对称摆线-销齿圆弧型型线,阴、阳转子齿数比为6:4。设计新型转子型线,目的是使接触线长度、泄漏三角形面积和封闭余隙容积3者达到最优化设计,以进一步提高双螺杆压缩机的机械性能。重点研究的是双螺杆压缩机的转子型线设计、几何特性、受力分析、热力学计算。

[Abstract]
The twin-pressor is a kind of newly pressor. Because of its high reliability, easy repair, good balance and good adaptability etc, and widely applied to such industrial departments as mine, chemical industry, power, metallurgy, architecture, machinery, refrigeration, etc. By designing the project, the volumetric efficiency is 70%, pressed temperature is more 80℃。It is very important to design and research a twin-pressor in industrial. The project is to design a universal twin-screw pressor, and to adopt single side asymmetric swept line unilaterally and dowel tooth circular rotor profile. There are six lobes on the female rotor and four lobes on the male rotor. The aim of designing a new rotor profile is to optimize the contact line length, blowhole area and clearance volume. That can improve the mechanical performance of a twin-pressor further. The project is mainly to research a twin-pressor rotor profile, geometry characteristic, mechanics analysis, thermodynamics calculation
