喷油螺杆压缩机的性能取决于许多设计参数,例如:转子的型线、转子的齿数、转子的长径比L/D、螺旋角、几何间隙、喷油量和喷油位置、排出口尺寸和排气速度等。掌握这些参数对压缩机性能的影响能够帮助设计者选出最好性能的压缩机以满足使用。本文系统地检验了上述几个参数对给定理论容积流量的压缩机的尺寸及性能的影响。用专有的计算机程序（1、2）计算转子的几何特性和压缩机性能。结果表明,正确选择设计参数能显著地改进压缩机性能,得到了几条极有价值的表示这些参数与压缩机尺寸及性能之间关系的曲线。
The performance of oil-injected screw compressors depends on many design parameters such as the rotor profile, the number of teeth in the rotor, the rotor’s L / D ratio, helix angle, geometric clearance, fuel injection and injection position, And exhaust speed and so on. Grasp the impact of these parameters on the performance of the compressor can help designers to select the best performance of the compressor to meet the use. This paper systematically tests the influence of the above several parameters on the size and performance of compressors with given theoretical volume flow. The rotor geometry and compressor performance are calculated using a proprietary computer program (1,2). The results show that the correct choice of design parameters can significantly improve compressor performance, and several very valuable curves representing the relationship between these parameters and compressor size and performance have been obtained.
