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).
The Two Stage Air Compressor Test Set Air Water Cooled is for studying the two stage reciprocating air compressor characteristics. The air receiver has a drain valve, a safety valve and a discharge valve. The piping system is arranged such that intercooler or second stage compressor can be by passed. An intercooler is provided between first and second stage. The unit is equipped with necessary measuring instruments and is on wheels. For educational purpose, the two stages are separated and can be operated at different speeds. Both stages are connected by vee-belts to the same motor with an advanced inverter. The second stage compressor has three alternative pulleys to vary the pressure ratio between the two stages.
Experiments:
Compressor characteristics eg. volumetric efficiency, isothermal efficiency, pressure ratio, temperature ratio.
Effect of second stage drive ratio.
Effect of compressor speed.
Effect of intercooler.
The Single Stage Air Compressor Test Set Air Cooled is for studying the single stage reciprocating air compressor characteristics. 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.
Compressor characteristics eg. volumetric efficiency, isothermal efficiency, pressure ratio, temperature ratio.
