2024年5月28日 · Impellers are the link between the power input (motor) and power output (fluid movement) of pumps. The pumping process starts as the motor rotates the impeller via the shaft. As the impeller turns, water is pushed from the center outward along the edge of vanes, which increases pressure.

A centrifugal pump containing two or more impellers is called a multistage centrifugal pump. The impellers may be mounted on the same shaft or on different shafts.
The impeller is the rotating component within the centrifugal pump design, which transfers the energy from the pump’s motor to the fluid. It is made up of vanes that come off an open inlet at the centre, known as the eye, which create a centrifugal force as they spin to move the liquid from the casing to the discharge point.
An impeller is a rotating component of a centrifugal pump that accelerates fluid outward from the center of rotation, thus transferring energy from the motor that drives the pump to the fluid being pumped.

How to optimize the performance of a centrifugal pump impeller?
The impeller is the main component of a centrifugal pump. When the impeller rotates, it generates the force required to move – or “pump” – the fluid. Impellers are also used in compressors, turbines and many other machines that move fluids or gas.
