Is the displacement of the air compressor equal to the working flow

The displacement of the air compressor is not equal to the working flow. Here are the detailed differences between the two:

definition

• exhaust volume:

  • concept: The displacement of the 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 expel from one stroke to another.
  • Unit: Usually cubic meters per minute (m & sup3;/min), some people will use standard liters per minute (L/s).
  • Calculation method: The displacement is a value obtained by theoretical calculation, which includes factors such as the compression ratio of the air compressor and the working volume of the cylinder.

• working flow:

  • concept: The working flow of the air compressor refers to the actual output flow of the air compressor, that is, the flow of compressed air at the outlet of the compressor.
  • Unit: Usually cubic meters per minute (m & sup3;/min) or cubic feet per minute (CFM).
  • Calculation method: The working flow rate is obtained by the measured value, which depends on the exhaust pressure of the compressor, the speed of the compressor, the intake air temperature and other factors.

Difference

1. different physical meaning:

   • the exhaust volume represents the volume of gas discharged by the air compressor per unit time, which more reflects the performance parameters of the compressor itself.
   • The working flow rate refers to the actual output of the air compressor, which is closer to the needs of the actual application.

2. Different application scenarios:

   • exhaust volume is usually used as the main parameter of the air compressor to evaluate whether the compressor can meet the specific compressed air demand.
   • The working flow rate is usually used to determine the specific application scenario of the air compressor, such as blowing and spraying of the production line.

3. numerical relation:

   • because the working flow is affected by a variety of actual operating factors, it may be different from the displacement. In some cases, the working flow rate may be less than the exhaust volume, because there may be pressure loss, leakage, etc. during the actual output process.
   • Conversely, under certain conditions (such as excessive compressor performance or low system demand), the working flow may be close to or equal to the exhaust volume.

Conclusion

in summary, the displacement of the air compressor is not equal to the working flow. When selecting and using air compressors, these two parameters should be comprehensively considered according to specific application scenarios and needs to ensure that the compressor can meet the requirements of actual production.
