What is the working principle of a centrifugal pump?

What is the working principle of a centrifugal pump?

The basic principle of operation of centrifugal pumps is – force vortex flow. This means, when a body of liquid is acted upon by an external torque, it increases the pressure head of the rotating liquid. This increase in pressure is directly proportional to the velocity of the liquid.

What is the principle function of pump?

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps.

What is the principle of centrifugal pump and reciprocating pump?

Reciprocating Pump is a Positive Displacement type pump that works on the principle of movement of the piston in forwarding and backward directions whereas the Centrifugal pump uses the kinetic energy of the impeller to supply the liquid from one place to another place.

Which motor is used in centrifugal pump?

DC shunt motor: It is an almost constant speed motor. Hence it is used for driving constant speed line shafts, lathes, centrifugal pumps, small printing presses, paper making machines, etc.

What are the parts of centrifugal pump?

Main Parts of a Centrifugal Pump

  • Impeller. An impeller is a rotor used to increase the kinetic energy of the flow.
  • Casing (Volute). The casing contains the liquid and acts as a pressure containment vessel that directs the liquid flow in and out of the centrifugal pump.
  • Shaft (Rotor).
  • Shaft sealing.
  • Bearings.

What is rotor in pump?

The rotor is fitted inside the stator which is lined with rubber. The rotor rotating inside the stator forms cavities via which media is pumped from suction to the discharge end of the pump. The rate of flow of the liquid is usually inversely proportionate to the pressure.

What is difference between pump and motor?

While a motor is itself a driving mechanism which can be used to power another device, a pump is a mechanical device which requires a driving mechanism in order to function. Motors use electrical energy to produce mechanical energy, while pumps in Lethbridge use mechanical energy to perform work.
