Air compressor gas consumption

The air consumption of air compressors is usually determined by a number of factors, including the type of equipment, specifications, working pressure, and actual work requirements. Generally speaking, the gas production (FAD) of the air compressor will be expressed in units such as m & sup3;/min, L/s, m & sup3;/h, etc., which refers to the ability of the air compressor to continuously produce gas per unit time.

When selecting the gas production of the air compressor, the gas consumption under the specific gas pressure needs to be considered. If you are not sure of your own gas consumption, you can contact the air compressor engineer, who can provide the flow and pressure information required by the equipment. In addition, the "compressed air diagnosis" can also obtain accurate air flow changes, which is usually done by the air compressor supplier.

In addition, the air consumption of the air compressor is also related to its power and volume flow. In the case of constant power, when the speed changes, the volume flow and working pressure will also change accordingly. For example, for a 22KW air compressor, the working pressure is determined to be 7bar during manufacture, the rotating speed is calculated according to the technical curve of the compressor host, and the displacement is 3.8 m & sup3;/min; When the working pressure is determined to be 8bar, the rotating speed must be reduced (otherwise the drive motor will be overloaded). At this time, the displacement is 3.6 m & sup3;/min. Because the speed is reduced, the displacement is also reduced accordingly.

In practical applications, some other factors need to be considered, such as the leakage of gas pipelines (usually about 5% of gas leakage is considered), and whether it is possible to increase gas consumption or add gas equipment in the future. In addition, as the use time increases, the gas consumption of the equipment may increase (usually in the range of 5% to 10%).

In summary, determining the air consumption of the air compressor is a relatively complex process, which requires comprehensive consideration of many factors. In order to ensure the purchase of air compressor specifications and configurations suitable for their own needs, it is recommended to conduct detailed consultation and communication with professional air compressor engineers or suppliers.
