The running characteristics of axial flow pump

run characteristics of axial flow pump

1, the use and management

axial-flow pump is a kind of high speed pump, general specific speed between 500 ~ 1000. Because the more the greater the speed, the lower the head, the greater the flow. Due to the qv - of axial flow water pump H performance curve is very steep fall, at the time of starting discharge piping valves should be closed, otherwise the starting power is too large, will cause the motor overload and damage. Axial flow adjustable vane pump is used to adjust flow.

2, characteristics and application of

the biggest advantage of axial flow pump is large flow, simple structure, light weight, small dimension, cover an area of an area small. To adjust type axial flow pump, when conditions change, as long as change the blade Angle, still can keep working under high efficiency, but because of hm is too low, the scope of its application is restricted. In order to improve the hm, made of multistage axial-flow pump can also be used. Axial flow pump cavitation performance is poorer, generally allow the vacuum suction height is only 4 ~ 5 mh2o ( 40 ~ 50 kpa) 。 Because of the characteristic of the axial flow pump itself has, so big flow is one of the developing direction of axial flow pump.
