双工作腔滑片压缩机气缸型线的研究及特性分析

分析了双工作腔滑片压缩机气缸的型线问题，建立了判别气缸型线优劣的准则，提出了气缸型线的生成原理，依据该原理构造出６ 种气缸型线并导出其特性方程．用判别准则分析这些型线时发现，简谐气缸型线的特性优于其它型线．通过分析简谐气缸型线的结构参数 相对升程对型线特性及工作腔容积的影响，优化出其合适的取值范围为０ ．２７ ～０ ．３５ ．最后对采用简谐气缸型线的滑片压缩机与涡旋式压缩机的性能作了比较，结果表明：简谐气缸型线是双工作腔滑片压缩机比较理想的气缸型线

Cylinder Profile of Double Acting Chambers for Vane Compressors

Analysis of cylinder profile is presented for the sliding vane compressor with double action. The formation obtained is a criteria for determining the desired profile. This is accomplished from studying the characteristic euqations for six different types of cylinder profile. The simple harmonic cylinder profile is better than the others. By analyzing the influence of the shape parameter (ratio of the lift to the third dimension) on the working chamber volume, an appropriate value between 0.27 and 0.35 is formed. Such a choice was the result of comparing the performance of the vane compressor with a simple harmonic profile with that of the scroll compressor. The former is superior.
