Air compressor volume flow

Volume flow is also called displacement or nameplate flow in China.

Generally speaking, under the required exhaust pressure, the volume of gas discharged by the air compressor per unit time is converted to the intake state, that is, the suction pressure at the first-stage intake pipe and the suction temperature and humidity. Volume value. That is, the volume of inhalation.

According to national standards, air compressors are qualified when the actual displacement of the air compressor is ±5% of the nominal flow.

If the speed does not change, the pressure change theoretically does not affect the displacement. Specifically, it affects the volume flow and does not affect the mass flow. Because what we generally call the exhaust volume refers to the intake air flow, there is no change.
