エアコンプレッサーの種類
Understanding the different types of air compressors can help in selecting the right one for your needs. Each type has its own advantages, disadvantages, and suitable applications, depending on factors such as required pressure, flow rate, air quality, and energy efficiency.
The two main categories of air compressors are positive displacement and dynamic compressors. Positive displacement compressors work by trapping a fixed volume of air and reducing its volume to increase the pressure. Dynamic compressors, on the other hand, use high-speed rotating impellers to impart velocity to the air, which is then converted to pressure.
ロータリースクリューコンプレッサー
ロータリースクリューコンプレッサー are the most common type used in industrial applications. They are positive displacement compressors that use two meshing helical screws to compress the air continuously. As the screws rotate, they trap air between them and the compressor housing, reducing the volume and increasing the pressure.
Advantages of rotary screw compressors include:
- High efficiency and energy savings potential
- Continuous air supply without pulsation
- Compact size and low noise levels
- Low maintenance requirements and long service life

Disadvantages include higher noise levels, pulsating air delivery, and lower efficiency compared to rotary screw compressors.
遠心圧縮機
Centrifugal compressors are dynamic compressors that use a high-speed rotating impeller to impart velocity to the air, which is then converted to pressure in a diffuser. They are typically used in large-scale, high-volume applications, such as in power plants, chemical processing, and oil and gas industries.
Advantages of centrifugal compressors include:
- High flow rates and efficiency
- Continuous, pulsation-free air delivery
