Is the air compressor’s exhaust volume equal to the working flow?

The air exhaust volume of the air compressor does not equal the working flow. Here are the detailed differences between the two:

Definition

• Exhaust volume:

  • Concept: The exhaust volume of an air compressor refers to the volume of compressed air discharged by the air compressor within a specified time. It represents the volume that a piston can discharge from one stroke to another.
  • Unit: Usually cubic meters per minute (m³/min), and some people will use standard liters per minute (L/s).
  • calculating method: The exhaust volume is a value calculated through theory, which includes factors such as the compression ratio of the air compressor, the working volume of the cylinder, etc.

• Working flow:

  • Concept: The working flow of an air compressor refers to the actual output flow of the air compressor, that is, the flow rate of compressed air at the compressor outlet.
  • Unit: Usually cubic meters per minute (m³/min) or cubic feet per minute (CFM).
  • calculation method: The working flow is worthwhile through actual measurement, and it depends on factors such as the exhaust pressure of the compressor, the speed of the compressor, the intake temperature, etc.

Difference

1. Different physical meanings:

   • The exhaust volume represents the volume of gas discharged by the air compressor per unit time, and it reflects more the performance parameters of the compressor itself.
   • The working flow refers to the actual gas output by the air compressor, which is closer to the requirements in actual applications.

2. Application scenarios are different:

   • Exhaust gas volume is usually used as the main parameter of the air compressor and is used to evaluate whether the compressor can meet specific compressed air needs.
   • The working flow is usually used to determine the specific application scenarios of air compressors, such as blowing, spraying, etc. of the production line.

3. Numerical relationship:

   • Because the working flow is affected by a variety of actual operating factors, it may have a certain difference from the exhaust volume. In some cases, the working flow may be less than the exhaust volume, becauseThere may be pressure loss, leakage and other problems during the international output process.
   • Conversely, under certain conditions (such as when compressor performance is excessive or system demand is low), the working flow may also be close to or equal to the exhaust volume.

Conclusion

To sum up, the air exhaust volume of the air compressor does not equal the working flow volume. When selecting and using an air compressor, these two parameters should be considered comprehensively based on the specific application scenarios and requirements to ensure that the compressor can meet the actual production requirements.
