Working principle of axial flow pump

The working principle of an axial flow pump involves the movement of fluid parallel to the pump shaft, utilizing propeller-like blades to generate flow. Here's a brief overview:

1. Propeller Rotation: The pump's propeller, driven by a motor, rotates within the pump casing. As it spins, the blades impart kinetic energy to the fluid.

2. Axial Flow: Unlike centrifugal pumps, axial flow pumps move fluid parallel to the shaft. The rotating blades push the fluid in a straight line along the axis of the pump.

3. Fluid Acceleration: The blades accelerate the fluid, increasing its velocity and creating a flow that moves directly through the pump.

4. Pressure Increase: While the primary function is to move large volumes of fluid, the design also generates a moderate increase in pressure as the fluid passes through the blades.

5. Discharge: The fluid exits the pump through the discharge outlet, continuing its path through the piping system.

Axial flow pumps are particularly effective for applications requiring high flow rates with relatively low pressure, such as in irrigation, flood control, and large-scale water circulation systems.
