Mixed flow pump from the shape, structure is the range of centrifugal and axial flow pump in between; mixed flow pump of the pumping principle, impeller of high-speed rotation, mixed flow pump is centrifugal pump centrifugal and axial flow pump push the lift, mixed flow pump by the mixing effect of the two kinds of force and pumping. Mixed flow pump function is also referred to between the centrifugal pump and axial flow pump, it and the centrifugal pump contrast, head low, and the flow is larger; it is compared with the axial flow pump, head higher, but the flow is smaller.
The use of mixed flow pump function to work parameters to show that. For example, flow, head, power, power, speed, etc.. In a certain speed, the flow is variable, that is, if you change the flow of the pump, the pump head, power and power and so on are changed. To change the rules of this relationship, the induction into several curves to indicate that this is the pump function curve. Mixed flow pump function curve shape is also a range of centrifugal pump and axial flow pump in between, a high head mixed flow pump, the relationship between the flow and head, flow and power change the rules closer to the centrifugal pump, in use, used in the closed valve start, when the minimum power, power machine safety. A low head mixed flow pump, the function between the parameters by changing the rules close to axial flow pump, in use, should not be used to start off valve, but should valves to start, when power is in contrast with the small, the motor is not easy to be burned.
