Centrifugal type rotary air compressor:
A centrifugal compressor, in its simplest form consists of a rotor (or impeller) to which no. of curved vanes are fitted symmetrically . .
The rotor rotates in an air-tight volume casing with inlet and outlet points.
The casing for the compressor is so designed that the kinetic energy of air is converted into pressure energy before it leaves the casing.
The mechanical energy is provided to the rotor from some external source.
As the rotor rotates, it sucks air through its eye, increases its pressure due to centrifugal force and forced air to flow over the diffuser.
The pressure of air is further increased during its flow over the diffuse. Then the air is delivered to the receiver.
