What is the air flow rate per minute of the air compressor?

The air flow rate per minute of the air compressor, that is, the displacement or volume flow rate of the air compressor, refers to the volume of gas sucked and compressed from the suction end to the output end of the air compressor per unit time. This indicator directly reflects the production capacity of the air compressor and is an important basis for evaluating the performance of the air compressor. The air flow per minute of the air compressor varies with various factors such as model, power, pressure setting and working conditions.

1. influencing factors

1. model: Different types of air compressors have different design structures and working principles, and their air outlet flow will also be different. Generally speaking, the air flow of large air compressor is higher than that of small air compressor.
2. Power: The power of the air compressor directly affects its outlet air flow. The higher the power, the greater the volume of gas that the air compressor can compress per unit time, and the gas flow rate increases accordingly.
3. Pressure settings: The working pressure setting of the air compressor will also affect the outlet air flow. Under the same conditions, the higher the working pressure, the more energy the air compressor needs to consume to compress the gas, which may lead to a decrease in the outlet gas flow.
4. Other factors: Such as leakage, suction process, cooling effect, filter blockage, speed, etc. will also affect the displacement of the air compressor.

2. flow range

according to market research and data provided by manufacturers, the normal air compressor gas output (I. e. gas flow per minute) range is usually between 5 cubic meters per minute to 1000 cubic meters. This range covers a variety of models from small domestic air compressors to large industrial air compressors. The specific flow rate also needs to be determined according to the actual use of the air compressor and the working environment.

3. calculation formula

the air flow per minute of the air compressor can be calculated by the following formula:

• q=V×n×60

among them, Q represents the air flow per minute (unit: cubic meters/minute),V represents the air compressor per revolution (unit: cubic meters/revolution), and N represents the speed of the air compressor (unit: revolution/minute). By consulting the technical specification table of the air compressor, the specific values of the displacement and speed of each revolution can be obtained, and then substituted into the formula to calculate the air flow per minute.

4. the displacement of different types of air compressors

1. miniature air compressor the exhaust volume is small, generally between 0.1~1 cubic meters/minute (standard square).
2. Piston air compressor: The exhaust volume ranges from a few cubic meters per minute for small households to hundreds of cubic meters per minute for large industries.
3. Screw air compressor: The exhaust volume is usually between a few cubic meters/minute and thousands of cubic meters/minute to meet the production needs of different scales.
4. Centrifugal air compressor: It is suitable for large-scale industrial occasions that require large flow and high-pressure air, and its exhaust volume is very large, which can reach thousands or even tens of thousands of cubic meters per minute.

5. Example Description

for example, if a certain type of air compressor has a displacement of 0.02 cubic meters per revolution and a rotation speed of 1000 r/min minutes, the air outlet per minute is calculated to be 12 cubic meters according to the formula.

In summary, the air flow per minute of the air compressor is a dynamic value, which is affected by many factors. When selecting and using air compressors, the appropriate exhaust volume should be determined according to actual needs and working conditions.
