对照叙述电压、电流和泵中扬程、流量的对应关系.电子元件单结晶体管的V-A特性曲线和轴流泵的Q-H性能曲线有相似之处,通过扬程和流量之间存在的数学关系,进一步讨论了轴流泵Q-H性能曲线上的稳定运行和不稳定运行两个工作区.
The relationship between voltage and current in the pump and the flow rate in the pump is described in this paper.The VA characteristic curves of the single-junction transistor in electronic components are similar to the QH performance curves of the axial-flow pump. The mathematical relationship between the head and the flow is discussed further The axial flow pump QH performance curve of the stable operation and unstable operation of the two work areas.
