How Does a Centrifugal Pump Work?
A centrifugal pump is a type of rotodynamic pump that uses centrifugal force to convert the energy of the motor and the rotation of the impeller into kinetic energy in the form of fluid flow. The impeller is the rotating part of the pump that creates the centrifugal force and the casing that contains it is the main body of the pump.
The working principle of a centrifugal pump is based on the theory of forced vortex flow. When a specific quantity of fluid or liquid is allowed to rotate by an impeller, it is forced to move outward due to the centrifugal force created by the rotation. This results in a pressure difference between the center and the periphery of the impeller, which causes the fluid to flow from the center of the impeller to the periphery. The pressure difference also increases the velocity of the liquid. As the fluid passes through the impeller, it is converted into kinetic energy, which is then used to move the fluid through the pump casing.
The centrifugal pump is preferred over other pumps because it is simple and efficient. It is also cost-effective and requires minimal maintenance, making it an ideal choice for many applications. Furthermore, it is capable of pumping liquids of different viscosities, making it suitable for a wide range of applications.
