Volumetric flow is also known as displacement or nameplate flow in China.
Generally speaking, at 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 nozzle and the suction temperature and humidity Volume value. That is, the volume of inhalation.
According to national standards, the actual discharge volume of the air compressor is ± 5% of the nominal flow rate and all are qualified.
If the speed does not change, the pressure change does not affect the displacement in theory, specifically, it affects the volumetric flow rate and does not affect the mass flow rate. Because we generally refer to the exhaust volume as the intake air flow, there is no change
