Features of axial flow pump and mixed flow pump | Edwin Pump

The working principle and characteristics of Edwin axial flow pump

1) Working principle of axial flow pump

The working principle of the axial flow pump is different from that of the centrifugal pump. It mainly uses the thrust generated by the high-speed rotation of the impeller to lift water. The lift generated by the blades of the axial flow pump on the water can push the water from below to above.

The blades of the axial flow pump are generally immersed in the pool of the suction source. Due to the high-speed rotation of the impeller, under the action of the lift generated by the blades, the water is continuously pushed upwards, causing the water to flow out along the outlet pipe. The impeller rotates continuously, and the water is continuously pressed to a high place.

2) The general characteristics of axial flow pumps

(1) The flow direction of water in an axial flow pump is suction and flow out along the shaft of the impeller, so it is called an axial flow pump. (2) Low head (1–13 meters), large flow, high efficiency, suitable for irrigation and drainage of plains, lake areas, and river network areas.

(3) No need to fill water before starting, easy operation.

Working principle and characteristics of Edwin mixed flow pump

1) Working principle of mixed flow pump

Because the shape of the impeller of the mixed flow pump is between the centrifugal pump impeller and the axial flow pump impeller, the working principle of the mixed flow pump has both centrifugal force and lift force. By the combined action of the two, water flows out of the impeller at a certain angle with the shaft. , Lift the water to a high place through the volute chamber and pipeline.

2) General characteristics of mixed flow pumps

(1) Compared with centrifugal pumps, mixed-flow pumps have lower head and larger flow. Compared with axial flow pumps, mixed-flow pumps have higher head and lower flow. Suitable for irrigation and drainage of plains and lake areas.

(2) Water is sucked and discharged at a certain angle with the impeller shaft along the flow direction of the mixed flow pump, so it is also called a diagonal flow pump.
