Compressor inlet flow rate

This post was last edited by sxf1028102800 on 2025-2-15 at 18:51. I’m looking at information related to piston compressors; when checking the parameters, the volumetric flow rate and inlet flow rate are 9.3 cubic meters per hour. It’s a hydrogen generator used in diesel hydrogenation – is the inlet flow rate really that low? I’m not quite sure. Usually, the outlet flow rate is several thousand cubic meters per hour. Those who know can please explain this. Thank you
The unit is correct, right? Minutes and hours
The inlet flow rate and outlet flow rate of a piston compressor are different concepts. An inlet flow rate of 9.3 cubic meters per hour refers to the volume of the raw gas drawn in at the compressor’s inlet. This relatively low value may be due to the compressor’s smaller design capacity or to the fact that it is operating at its initial stage. The export flow rate of several thousand cubic meters refers to the flow rate after compression, when the volume of the gas decreases and the pressure increases. Therefore, although there is a large difference in the values of the inlet and outlet flows, this is normal because the state of the gas changes during the compression process. .
Is the data incorrect? The inbound traffic is way too low; the outbound traffic during operation is in the thousands of cubic meters
An inlet flow rate of 93 cubic meters per hour is indeed too low for compressors that need to produce several thousand cubic meters of compressed gas. It might be an error in the labeling of the data, or it could refer to the flow rate under a specific operating condition. It is recommended to verify the original parameters or contact the equipment manufacturer for more accurate information. At the same time, it is necessary to confirm whether this flow rate value was measured under specific conditions, such as flow rate at certain pressure or temperature conditions. .
It is recommended to take into account the factors related to pressure; the flow rate under such pressure should be accurate. Also, consider the motor power as a reference for further consideration.
It must be the unit that’s wrong; it should be 9.3 m³/min.
If the content of the photo is accurate, then unless the inlet temperature is extremely low (but theoretically, the lowest possible temperature is -273°C), the exhaust flow rate will not exceed one-third of the inlet flow rate; in any case, this does not match the description of an outlet flow rate of several thousand cubic meters.
It should be in minutes; that’s more reasonable, unless it’s a mini air compressor
The inlet flow rate of a compressor generally refers to the flow rate under suction conditions, not under standard conditions. With a high inlet pressure, the suction flow rate should be low; however, 9.3 m3/h seems a bit too high.
