Structural Characteristics of Horizontal Mixed flow Pump

Horizontal mixed flow pump from the shape, the structure is between the centrifugal pump and axial flow pump; mixed flow pump principle, the high-speed rotation of the impeller, mixed flow pump both produce centrifugal centrifugal force, but also has the axial lift pump lift, The mixed flow pump is pumped by the mixing of these two forces. Mixed-flow pump performance is also between the centrifugal pump and axial flow pump, and centrifugal pump compared to the lower head, while the flow of some larger; it compared with the axial pump, the lift higher, but the flow is smaller. This is a vast territory for our country, the terrain is complex, more of a pump according to local conditions of choice.
The mixed-flow pump is the main equipment for the transportation and upgrading of water in the pumping station. In the water supply and drainage works of the towns and industrial enterprises, the large-scale water pump is the vane type pump, and the centrifugal pump is the most common. Mixed pump pumping principle, the high-speed rotation of the impeller, both the centrifugal force of the centrifugal pump, but also has the axial lift pump lift force, mixed flow pump by the combination of these two forces pumping. Mixed-flow pump performance is also between the centrifugal pump and axial flow pump, and centrifugal pump compared to the lower head, while the flow of some larger; it compared with the axial pump, the lift higher, but the flow is smaller.
When the original motive drive impeller rotation, the role of the liquid both centrifugal force and axial thrust, centrifugal pump and axial pump is a comprehensive. So it is a pump between the centrifugal pump and the axial flow pump. The flow rate of the mixed flow pump is higher than that of the centrifugal pump, which is lower than the axial flow pump, usually between 300-500. Its head is higher than the axial pump, but the flow rate is lower than that of the centrifugal pump than the centrifugal pump. Mixed flow pump is mainly used for agricultural irrigation and drainage, and also for urban drainage, can be used as a thermal power plant circulating pump.
