For axial flow pumps, how do head and power change with flow rate? ?
Thread Content
Generally, both head and flow rate decrease gradually as the pump flow rate increases. However, there is a turning point in this trend: as the flow rate increases, head and power instead increase gradually before decreasing again. How should I understand the turning point?
This is the characteristic of the performance curve of axial flow pumps: a saddle shape appears at low flow rates.
