1. Use and management:
Axial flow pump is a high specific speed of the pump, generally more than the speed between 500 ~ 1000. Because of the greater the speed, the lower the head, the greater the flow. Because the qv-H performance curve of the axial flow pump is very steep, the discharge pipe should not be closed on the starting line, otherwise the starting power is too large, it will cause the motor overload and damage. The axial flow pump adopts adjustable vane pump to adjust the flow rate.
2. Characteristics and Applications:
The biggest advantage of axial flow pump is large flow, simple structure, light weight, small size, small area. For regulating axial flow pump, when the working condition changes, as long as the change of blade angle, still can keep in high efficiency, but because of Yang Chengtai low, its application scope is limited. In order to improve Yang Cheng, axial flow pump can also be made into a multi-stage.
Axial flow pump cavitation performance is poor, generally allow suction on the vacuum is only 4 ~ 5mH2O (40 ~ 50kPa). Because the axial flow pump has its own characteristics, so the flow is one of the development direction of axial flow pump.
