Common parameters of air compressor

1. Exhaust volume (ie volume flow)

At the rated exhaust pressure, the air volume discharged by the air compressor per unit time is converted to the air volume under the intake state, which is the air displacement (ie volume flow) of the air compressor. The unit is m³ / min. In layman's terms, the air compressor's exhaust volume refers to how much cubic air is sucked into the machine's air inlet per minute, rather than how much cubic air can be discharged from the machine's exhaust port every minute.

2. Exhaust pressure

The air compressor discharge pressure refers to the gas pressure (gauge pressure) finally discharged from the compressor, and the unit is: Mpa. The air compressor industry commonly uses "kg" as the pressure unit, 1 kg = 0.1Mpa. The discharge pressure marked on the nameplate of the air compressor is called the rated discharge pressure, which is also the maximum discharge gauge pressure allowed by the compressor. Exhaust volume and exhaust pressure are two very important parameters of an air compressor.

3. Air compressor exhaust temperature

The air compressor exhaust temperature refers to the temperature of the air discharged from the air outlet of the main unit (head) of the air compressor, in ℃ or ℉. The compressor discharge temperature is an important indicator of compressor safety. Due to the nature of the compressed gas, lubricating oil, temperature resistance of the sealing material, rotor running clearance and other factors, the exhaust temperature is limited, and the exhaust temperature is an important performance parameter of the air compressor unit.

4. Unit input power

Unit input power refers to the total input power of the air compressor unit (power measured from the three-phase input bus end), the unit is KW.

5. Unit input specific power

Unit input specific power refers to the ratio of the unit's input power to the exhaust volume under the specified exhaust pressure of the air compressor unit: unit input specific power = unit input power / exhaust volume

The unit is: kW / (m3 / min). According to "GB19153 Volumetric Air Compressor Energy Efficiency Limit Values and Energy Efficiency Levels", the specific power of air compressor units at different pressures has different power efficiency level limits.
