Scroll air compressor screw type difference

There are several major differences between scroll air compressors and screw air compressors, as follows:

design principle:

the scroll air compressor is composed of two double function equation type lines of dynamic and static scroll meshing with each other. In the process of suction, compression and exhaust, the static disc is fixed on the frame, and the moving disc is driven by the eccentric shaft and restricted by the anti-rotation mechanism, and rotates on a plane with a small radius around the center of the static disc base circle. The gas is sucked into the periphery of the static disc through the air filter element. As the eccentric shaft rotates, the gas is gradually compressed in several crescent-shaped compression chambers combined by the static and dynamic disc, and then continuously discharged from the axial hole of the central part of the static disc.

The screw air compressor adopts high-capacity compression components, and its rotor outer circle speed is low and achieves better oil injection, achieving high efficiency and high reliability. The yin and yang rotors and the cooperation between the rotor and the casing are set, so that the backflow leakage of gas is less, and there is no gap volume, so the efficiency is high. The injected lubricating oil has the functions of sealing, cooling and lubrication. Compared with the piston machine, it has fewer wearing parts and low failure rate.

Product Features:

scroll air compressors are characterized by high reliability, very low noise, minimal energy consumption, and minimal maintenance. It has novel structure, small size, light weight, easy operation, and fewer host parts and fewer wearing parts, which greatly reduces the possibility of parts replacement. At the same time, the replacement of spare parts cycle is long, easy to use, less maintenance workload, low maintenance costs.

Screw air compressor has the advantages of high stability, high efficiency, low vibration and low noise. Its unique compression principle and design make it very efficient, and the noise and vibration in operation are relatively small. In addition, the cooling methods of screw air compressors are generally divided into water cooling and air cooling. The heat dissipation system adopts a plate-fin structure to ensure that the cooler has high pressure resistance, high heat dissipation efficiency, and good corrosion resistance.

Application condition:

scroll compressors are mostly used in air conditioners and other working conditions that require low noise and high reliability. They are favored because of their small torque change, high balance, low vibration, stable operation, simple operation, and low noise.

Screw air compressor is because of its high operability, good power balance, strong adaptability and other characteristics, in a variety of conditions have a wide range of applications, especially the need for high efficiency and high stability of the occasion.

In summary, there are significant differences between scroll air compressors and screw air compressors in terms of design principles, product characteristics and application conditions. The choice of which type of compressor depends on the specific needs and scenarios.
