摘　　要：通过进行单螺杆泵特性参数随泵出口管线结构及吸入口管线结构变化的试验研究，绘出了泵的特性参数与出口压力、吸入口真空度的关系曲线。试验结果表明，改变泵出口管线结构，使泵出口压力在一定范围内工作时，流量变化大，而且泵效率较高，可以作为泵调整参数的一种手段；而改变泵吸入口管线结构不宜作为泵的调整参数手段。Abstract The single scew pump characteristic parameter interrelationship curves with the pump outlet pressure and the suction vacuum was drawn after the test, the characteristic parameter was affected by the alteration of the outlet line and the suction line structure, was done. The test results have proved that the flow rate widely varied and the pump efficiency is high when the pump outlet line structure was altered and the outlet pressure was controlled in a special limit. To vary the pump outlet line structure could be one method of adjusting the pump characteristic parameter.
