The test rig includes a single-stage air compressor, an orificed air tank, pressure gauges, an energy metre to monitor input, and a temperature indicator to detect temperatures at various locations. The compressor is situated on an air receiver with the motor and contains a pressure switch and an air relief valve (safety). At various discharge pressures, the device estimates isothermal and volumetric efficiency

SPECIFICATIONS:

• A single-stage, single-cylinder air compressor powered by a 2 hp motor. A three-phase motor with a delivery valve is installed atop an air receiver.
• A water manometer is used with an air tank and aperture to monitor air intake.
• A pressure gauge to gauge discharge pressure.
• A temperature display on a computer.
• To gauge input power, use an energy metre.
•  The equipment is accompanied by a technical manual.

SERVICES REQUIRED:

• Floor space of 2.5 X 1,5m.
• 440 V, 15A, 3ph. AC supply with neutral and earthing connection.
• A hand tachometer.
