Relationship between air consumption and air compressor configuration

Basic parameters are required:

1. The size of the pressure (generally expressed in units such as MPA or BAR or kilograms) is determined according to the size of the aerodynamic force you need.

2. Exhaust volume (M & sup3 is used for general standards;/MIN as a unit) The size of the exhaust volume is related to the size of the air volume you need and the related equipment you need. The more links you go through, the greater the air volume.

Air consumption (air compressor displacement) is related to the pressure, but it has little to do with it. If the displacement exceeds the range specified in the air compressor specification, the pressure will be affected. So the air compressor selection is very important.

What is the relationship between air compressor power and working pressure and volume flow? First of all, we first understand the definition of the three.

1. What is the working pressure of air compressor?

The working pressure of the air compressor is often called the exhaust pressure by domestic users. Refers to the highest pressure of the air compressor discharge gas. The commonly used working pressure unit is bar or Mpa, and the conversion method is: 1 bar = 0.1 Mpa. Many users usually refer to the pressure unit as Kg, and the conversion method is: 1 bar = 1Kg.

2. What is the volume flow of air compressor? Volume flow, domestic users often called displacement or nameplate flow. It refers to the amount of gas volume discharged by the air compressor per unit time converted to the intake state under the required exhaust pressure. Volume flow unit: m & sup3;/min or L/ min, generally, the commonly used flow unit is: m & sup3;/min. The conversion method is: 1m & sup3;= 1000L.

The power of the air compressor refers to the nameplate power of the matched drive motor or diesel engine. The unit of power is KW or HP. The conversion method is: 1KW & asynmp; 1.333HP. Generally, the power of an air compressor refers to the nameplate power of the matching drive motor or diesel engine; the unit of power is: KW (kilowatt) or HP (horse/horsepower),1KW & asynmp; 1.333HP.

Finally, we look at the relationship between the three:

under the condition of constant power, when the rotation speed changes, the volume flow rate and working pressure also change accordingly. For example, for a 22KW air compressor, the working pressure is determined to be 7bar during manufacture, and 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 driving motor will be overloaded), the exhaust volume is 3.6 m & sup3;3/min; Because the speed is reduced, the exhaust is also reduced accordingly, and so on.
