Scroll air compressor and screw air compressor have their own advantages and applicable scenarios, and it is impossible to generalize which one is better. Here is a comparison of these two air compressors from several key aspects:
How it works:
The scroll air compressor uses the meshing of the rotor and the stator to form a plurality of compression chambers, and the volume of the compression chamber is changed through the translational rotation of the rotor, so as to realize the intake and compression of gas.
The screw air compressor achieves the purpose of compressing air by changing the volume of the cogging of the yin and yang rotors that are installed in parallel to each other in the casing.
Working conditions and characteristics:
The scroll air compressor has the characteristics of small torque change, high balance, low vibration, smooth operation and low noise, and is more suitable for places that require low noise and vibration such as air conditioning.
Screw air compressors are widely used in a variety of industrial fields because of their high operability, good power balance and strong adaptability.
Performance & Maintenance:
The structure of the scroll air compressor is relatively simple, small and lightweight, and because there is no metal contact during operation, it has less wear and high mechanical efficiency. However, it requires a high level of precision and presents certain challenges in high-horsepower applications.
Screw air compressors are favored for their simple structure, small size, no wearing parts, reliable work, long life, and simple maintenance. In particular, the twin-screw air compressor also has the advantages of low noise and energy saving.
In summary, scroll air compressor and screw air compressor have their own advantages, and which one is better to choose depends on the specific application needs and scenarios. In environments that require low noise and low vibration, such as hospitals, laboratories, etc., scroll air compressors may be more suitable; In the industrial field, especially when high pressure and large flow are required, screw air compressors have more advantages.
