DOUBLE STAGE AIR COMPRESSOR TEST RIG

The present set-up is designed tostudy the Double Stage Air compressor. The set-up consists of a double stagereciprocating type air compressor. It is driven by a motor through a belt andpulley system. The drive motor is swinging field type and supplied with dialtype spring balance which permits direct torque measurement.

This arrangement facilitates the enduser to calculate the power transmitted by the motor to the compressor,accurately. To calculate input power to the motor, an energy meter is providedand in this way, by knowing the input and output, efficiency of the compressoris calculated easily. The outlet of the air compressor is connected to airreservoir and suction is connected to another air manifold tank.

The compressor draws air from thismanifold tank which is provided with bellow at one side. This tank also has anorifice with manometer to observe and calculate the air flow rate. Thecompressed air from the outlet side of the compressor is stored in providedreservoir. The reservoir is equipped with Pressure Gauge, Control Valve, SafetyValve, Drain etc. A water cooled intercooler for air, in between both head, isprovided to cool the hot and compressed air before entering the second stage.

Temperature of inlet air, aftersingle compression, inlet and outlet of second compression and pressure inreservoir and at intermediate stage can be measured by Temp. Sensors andpressure gauges.
