单螺杆气体压缩机工作过程分析与计算

Analysis and Calculation of the Working Process of Single-screw Compressor

对单螺杆压缩机工作过程进行了分析 ,并根据螺杆和星轮间隙泄漏的特点 ,采用可压缩流体在渐缩喷管中流动模型来模拟气体的泄漏过程 。

The process of single screw compressor is analyzed. According to the characteristic of clearance leakage between the screw and wheel,a flow model of compressible fluid in a convergent nozzle is used to simulate a leakage process of the fluid and the calculating method of the insulation efficiency and the volume efficiency of single screw compressor is obtained.
