Centrifugal Pump Function and Components

A centrifugal pump uses a rotating impeller to move liquid through a stationary casing. The impeller, driven by an electric motor, creates centrifugal force that pushes liquid outward, increasing its velocity and creating a low-pressure zone at the impeller's center. This allows more liquid to flow into the pump. The impeller's veins guide the liquid to the volute, a channel that collects and directs it to the discharge port.

What are the main components of a centrifugal pump?

• Impeller, shaft, and casing

• Piston, cylinder, and valve

• Rotor, stator, and coil

• Blade, hub, and diffuser

What role does the electric motor play in a centrifugal pump?

• It rotates the impeller

• It cools the pump

• It measures the pressure

• It filters the liquid

How does the impeller increase the liquid velocity?

• By compressing the liquid

• By creating a vacuum

• By heating the liquid

• By centrifugal force

What is the purpose of the low-pressure zone at the eye of the impeller?

• To reduce the pump speed

• To stop the liquid flow

• To increase the temperature

• To allow more liquid to enter

What is the function of the volute in a centrifugal pump?

• To heat the liquid

• To filter the liquid

• To collect and direct the liquid

• To compress the liquid
