用清水及清水和空气两相混合物对单螺杆泵的外特性进行了试验研究 ,得到了在不同气液容积比下的外特性曲线 ,分析了外特性曲线的变化特点 ,为合理选泵提供一定的依据。
The external characteristics of the single screw pump were studied by using two-phase mixture of water and clean water and air. The external characteristic curves at different gas-liquid volumetric ratios were obtained. The changing characteristics of the external characteristic curves were analyzed. The basis.
