What are the reasons for insufficient flow of screw pump1. Due to the small amount of water entering the pump, it cannot keep up with the amount of water exiting the pump.Solution: increase the flow at the inlet of screw pump.2. The inlet pipe seal of screw pump is not properly handled, for example,

Shock absorption measures for axial flow pump units1. Adjust the operating conditions of vertical axial flow pumps by changing the angle, adjusting the speed, or bypass valve to reduce the necessary NPSH of the axial flow pump, bypass the cavitation operating point.2. Take effective drainage, waterp
