The working principle and characteristics of axial flow pumps

1. Working principle of axial flow pump

The working principle of an axial flow pump is different from that of a centrifugal pump, as it mainly utilizes the thrust generated by the high-speed rotation of the impeller to lift water. The lifting force generated by the rotation of axial flow pump blades on water can push water from below to above.

The blades of an axial flow pump are generally submerged in the water pool of the water source being sucked in. Due to the high-speed rotation of the impeller, the lifting force generated by the blades continuously pushes the water upwards, causing it to flow out along the outlet pipe. The impeller rotates continuously, and the water is continuously pushed to a high place.

2. General characteristics of axial flow pumps

(1) The flow direction of water in an axial flow pump is along the axial suction and axial outflow of the impeller, hence it is called an axial flow pump.

(2) Low head (1-13 meters), large flow rate, high efficiency, suitable for drainage and irrigation in plains, lake areas, and river areas.

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