What are the advantages and disadvantages of a scroll air compressor compared with scroll compressor?

31 Jul.,2025

Advantages of screw air compressor Screw compressors and piston scroll compressors, are both positive displacement compressors. In terms of usage effect, screw air compressor has the following advantages: 1. High reliability. The screw compressor has few components and no vulnerable parts, so it operates reliably and has a longer service life. The overhaul interval can reach 40000 to 80000 hours.

 

Advantages of screw air compressor

Screw compressors and piston scroll compressors, are both positive displacement compressors. In terms of usage effect, screw air compressor has the following advantages:

1. High reliability. The screw compressor has few components and no vulnerable parts, so it operates reliably and has a longer service life. The overhaul interval can reach 40000 to 80000 hours.

2. Easy to operate and maintain.Operators/workers do not need to undergo long-term professional training, enabling unmanned operation.

3. More Intelligent and high efficiency: Screw compressors have a high degree of automation, use frequency permanent magnetic motor and variable frequency converter, can realize 5G remote control.

4. Good power balance. Screw compressors do not have unbalanced inertial forces, and the machine can operate smoothly and at high speeds without a foundation. They are particularly suitable for use as mobile compressors, with small size, light weight, and small footprint.

5. Strong adaptability. Screw compressors have the characteristic of forced gas delivery, and their volumetric flow rate is almost unaffected by exhaust pressure. They can maintain high efficiency over a wide range and are suitable for various working conditions without any changes to the compressor structure.

Disadvantages of screw air compressor:

1. The rotor tooth surface is a spatial curved surface that requires the use of special cutting tools for processing on expensive equipment. The machining accuracy of the body components also has high requirements, and high-precision equipment must be used:

2. Due to limitations such as rotor stiffness and bearing life, the compressor can only rely on gap sealing inside, so screw compressors can only be used in the medium and low pressure range and cannot be used in high-pressure applications;

3. Due to the large fuel injection volume and complex oil treatment system, there are many auxiliary equipment in the unit;

Application of screw air compressor

Screw type air compressors are widely used in various industrial fields such as machinery, metallurgy, electronic power, medicine, packaging, chemical industry, food, mining, textile, transportation, etc., and have become the mainstream product of compressed air compressors.
