双涡圈及多涡圈涡旋机械几何特性的理论研究

分析了大排气量单涡圈涡旋式机械设计中存在的问题，进而提出以涡圈以及多涡圈的几何理论以及结构参数的设计计算方法，通过对单涡圈、双涡圈和多涡圈的容积特性比较，得出采用双涡圈或多涡圈理论设计涡旋机械，既可以达到减少回转半径、降低滑动面摩擦速度及降低磨损，又可以不减少有效吸气容积，从而可采用提高转速的方法来提高排气量，为大排气量涡旋机械的开发提供了理论基础。

Improved Characteristics of Scroll Machines with Multiple Spiral

As an improvement over the design of multiple spiral scroll machine for large displacement, two or multiple spiral scroll compressors could be designed to reduce the orbiting radius for the same displacement and hence velocity. This lowers friction and wear, and makes possible the development of scroll machine with large displacement.
