I. common terms for air compressors
Usually the discharge pressure on the compressor nameplate is indicated by surface pressure and non absolute pressure.
Commonly used pressure units: bar, MPa, air compressor industry "kilograms" refers to "bar", that is, 1 kilograms refers to 1bar, 1MPa (Zhao Pa) =1000kPa (Qian Pa), 1bar (BA) = 0.1MPa.
• Volumetric flow rate
In China, it is also known as discharge volume or nameplate flow. The volume of gas discharged in the unit time of the air compressor is converted to the intake state, that is, the volume of suction. According to the national standard, the actual displacement of the air compressor is equal to 5% of the nominal flow rate. Commonly used units: m, /min, L/s.
• Oil content of gas
The quality of the oil contained in compressed air (including oil droplets, suspend
