Centrifugal air compressors are a commonly used type of air compressor, mainly used for high-pressure air supply in industrial production. The main performance parameters of centrifugal air compressors will be introduced below.

1. Pressure range

The pressure range of a centrifugal air compressor is typically between 0.7MPa(absolute pressure) and 2.5MPa, which can be adjusted according to different requirements. The outlet pressure of a centrifugal air compressor is usually higher than 0.7MPa to meet the demand for high-pressure air in industrial production.

2. Exhaust flow rate

The exhaust flow rate of a centrifugal air compressor refers to the volume of air discharged from the compressor within a unit of time. Exhaust flow is usually measured under standard conditions, that is, the reference conditions are 20℃ and 1 atmosphere pressure, and the units are usually cubic meters per minute (m ³ /min) or cubic meters per hour (m ³ /h). Exhaust flow rate is one of the important indicators for measuring the performance of centrifugal air compressors.

3. Power

The power of a centrifugal air compressor refers to the rated power of the motor of the air compressor, usually expressed in kilowatts (KW). The power size directly determines the operating capacity and energy consumption level of the centrifugal air compressor.

4. Efficiency

The efficiency of a centrifugal air compressor is usually measured by the power conversion efficiency between the motor and the compressor. High-efficiency centrifugal air compressors can maximize the utilization of input electrical energy, converting it into compressed air while reducing energy loss and waste.

5. Noise

Centrifugal air compressors will generate certain noise during operation. Noise levels are usually measured in decibels (dB). For some noise-sensitive environments, such as office areas or areas close to residences, low-noise centrifugal air compressors should be selected.

6. Control mode

The control methods of centrifugal air compressors usually include constant pressure control and variable frequency control. Constant pressure control usually uses pressure switches to control the start and stop of air compressors, and is suitable for occasions with relatively stable demands. Variable frequency control automatically adjusts the rotational speed of the air compressor according to the actual gas demand, achieving energy conservation and stable operation.

7. Exhaust temperature

Centrifugal air compressors generate heat during operation. The exhaust temperature refers to the temperature of the compressed air at the outlet of the centrifugal air compressor. The exhaust temperature is related to factors such as the air compression ratio and cooling method, and it is also an important indicator for evaluating the performance and operating status of centrifugal air compressors.
