Centrifugal Pump Velocity Triangle Explained

This presentation discusses centrifugal pumps and the velocity triangle for centrifugal pumps. It defines centrifugal pumps as turbomachines that use rotational kinetic energy to transport fluids.

DEFINATION OF CENTRIFUGAL PUMPS

Centrifugal pumps are a sub-class of dynamic axisym metric work-absorbing turbomachinery.

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow.

The rotational energy typically comes from an engine or electric motor.

The fluid enters t he pump impeller along or near to the rotating axis and is acceler ated by the impeller, flowi ng radia lly outwar d into a diff user or volute chamber (casing), from where it exits.

An impeller attached to the rotating shaft. The impeller consists of a number of blades, also sometimes called vanes, arrange d in a regular patte rn around the shaft.

A stationary casing, housing, or volute enclosing the impeller.

The casing shape is designed to reduce the velocity as the fluid leaves the impeller, and this decrease in kinetic energy is converted into an increase in pressure.

The volute-shaped casing, with its increase area in the direction of flow, is used to produce an essentially uniform velocity distribution as the fluid moves around the casing into the discharge opening
