What Is Axial Flow Pump?

Axial flow pump is a pump that uses the rotation of the impeller to generate the kinetic energy of the fluid, which is mainly used for transporting fluids. It is characterized by large flow, low head, suitable for low head, large flow occasions.

The impeller design of the axial flow pump is special, and the flow and head can be changed by adjusting the Angle of the blade. Axial flow pumps have higher efficiency, but are limited by the adjustment range of the head, and are generally only suitable for specific head and flow ranges. The conveying medium of the axial flow pump is generally water, liquid, etc., and can also be used for gas transportation, but special sealing and lubrication methods are required.

The working principle of the axial flow pump is mainly to use the high-speed rotation of the impeller to provide the power of water flow. Specifically, the impeller structure of the axial flow pump is special, so that the flow direction of the water in the pump is parallel to the axis. When the water enters the inlet of the axial flow pump, the impeller begins to rotate, and the water flows to the outlet through the rotation of the impeller. The shape of the blade on the impeller forces the water to move in the direction of rotation of the impeller, creating an axial thrust that enables the water to be transported.

Axial flow pump has vertical, horizontal, inclined and tubular several kinds. Axial flow pumps are generally single-stage, and a few are made into two-stage pumps. Axial flow pump blades are divided into fixed and adjustable structures.

Axial flow pump is mainly used in ship cabin, ballast water tank, cargo hold and other occasions of liquid transportation. The design and manufacture of axial flow pumps need to take into account various factors, such as efficiency, reliability, wear resistance, explosion-proof, etc., to ensure its safe, stable and long-life operation.
