　Power, pressure, volumetric flow are several important indicators to judge the quality of air compressors, so what is the relationship between air compressor power and working pressure and volumetric flow? Before that, Chigo screw air compressor takes you to understand the definition of the three.

Power, pressure, volumetric flow are several important indicators to judge the quality of air compressors, so what is the relationship between air compressor power and working pressure and volumetric flow? Before that, ZEGA screw air compressor takes you to understand the definition of the three.

Q: What is the working pressure of ZEGA screw air compressor?

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

　　Q: What is volumetric flow of ZEGA screw compressor?

　　A: Volumetric flow, domestic users often call exhaust volume 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. The volumetric flow unit is: m3/min or L/min, generally, the commonly used flow unit is: m3/min. The conversion method is: 1m3=1000L.

　　Q: What is the power of ZEGA screw air compressor?

　　A: 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≈1.333HP.

　　(1) Generally, the power of the air compressor refers to the nameplate power of the matched drive motor or diesel engine;

　　(2) The unit of power is: KW (kilowatt) or HP (horsepower), 1KW≈1.333HP.

Second, let's look at the relationship between the three:

　　In ZEGA screw compressorUnder the condition that the power is unchanged, when the speed changes, the volumetric flow rate and working pressure also change accordingly; For example: a 22KW air compressor, the working pressure is determined to be 7bar during manufacturing, the speed is calculated according to the technical curve of the compressor host, and the exhaust volume is 3.8m3/min; When the working pressure is determined to be 8bar, the speed must be reduced (otherwise the drive motor will be overloaded), at this time, the exhaust volume is 3.6m3/min; Because, the speed is reduced, the exhaust is reduced accordingly, and so on.
