Two Stage Air Compressor Test Set Air Cooled

The Two Stage Air Compressor Test Set Air Cooled is for studying the two stage reciprocating air compressor characteristics. Air cooling between the two stages is by finned tubes. The air receiver has a safety valve, a drain valve and a discharge valve. The unit is equipped with necessary measuring instruments and is on wheels. An industrial type compressor is driven via a vee-belt by a motor with an advanced inverter.

Experiments:
Effect of compressor speed.
Effect of inter cooling (optional).
Compressor characteristics eg. volumetric efficiency, isothermal efficiency, pressure ratio, temperature ratio.
Air water heat exchanger demonstration (optional).
