What are the performance characteristics of axial flow pump?

1, use and management, axial flow pump high specific speed pump general specific speed 500 ~ 1000 due to the higher speed the lower head flow more due to the axial flow pump qv-H performance curve steeply drop should be discharge pipeline valve closed otherwise power generator motor-mounted damage axial flow pump adopts adjustable vane pump to regulate flow.

2. Features and applications, axial flow pump advantages of flow, simple structure, light weight, shape and size, area adjustment of axial flow pump working conditions change to change the blade angle still maintain a higher efficiency work because Yang Cheng is too low and its application range is limited to improve the Yang Cheng axial flow pump grade. The poor cavitation performance of axial flow pump generally allows the suction vacuum height only 4 ~ 5mH2O (40 ~ 50KPA) due to the axial flow pump's own characteristics of flow axial flow pump development. At present, the development of large caliber axial-flow pump structure has become more and more important.
