摘要

本文讨论了涡旋压缩机数学建模的一些方面。介绍了根据体积压缩原理对机器工作过程进行建模的各种方法、它们的应用价值和使用优先级。对应用于涡旋压缩机的压缩介质泄漏计算方法进行了分析综述,其中考虑了槽的分类。得出的结论是,需要澄清假设,并通过考虑间隙壁的流动性这一事实来改进这一技术,这取决于各种因素对压缩介质泄漏的影响份额。以及这一事实对计算精度和压缩机运行模式的最佳选择的影响。举例说明,在设计新样本时,在转换的方程组中考虑这一条件将提高螺旋机械工作过程的应用计算精度。

Scroll compressor. Analysis of calculation methods
The paper deals with some aspects of mathematical modeling of a scroll compressor. Various approaches to modeling the working processes of machines of the volumetric compression principle, their applied value and priority of use are presented. An analytical review of the methods for calculating the leakage of a compressed medium, applied to a scroll compressor, taking into account the classification of slots, is carried out. Conclusions are made about the need to clarify the assumptions and improve this technique by taking into account the fact of the mobility of the walls of the gap, depending on the share of the influence of various factors on the leakage of the compressed medium. And also about the influence of this fact on the accuracy of calculations and the optimal choice of the operating mode of the compressor. Examples are given in which taking this condition into account in the transformed systems of equations will improve the accuracy in applied calculations of the working processes of spiral machines, when designing new samples.
