Comparison: Screw, Centrifugal and Reciprocating Laser Cutter Compressors

At present, centrifugal, screw and reciprocating are the three most common types of laser cutter compressors, which differ in working principle, performance characteristics, application range, etc. This article will comprehensively introduce the basic situation of these three types of compressors for your reference.

Centrifugal Air Compressor

Centrifugal air compressor is a speed compressor that relies on high-speed rotating impeller to generate centrifugal force, so that the air is affected by centrifugal force and generates pressure.

The main advantages of centrifugal laser cutter compressors include large exhaust volume, uniform exhaust, no pulse of air flow, no need for lubrication in the machine, good sealing effect, less leakage, flat performance curve, wide operating range, easy to realize automation and large-scale.

Its scope of application is mainly in large and medium flow, medium and low pressure occasions.

Screw Laser Cutter Compressor

It is a positive displacement compressor. Through a pair of screws rotating in the machine cylinder, the gas between the screw teeth continuously produces volume changes, completing the three working processes of suction, compression and exhaust.

The advantages of screw air compressors include simple operation, low requirements for operators, forced gas transmission, volume flow rate is almost unaffected by exhaust pressure, and can maintain high efficiency in a wide range. However, its main disadvantages include high cost, not suitable for high-pressure occasions, not suitable for small exhaust volume occasions, large maintenance and high maintenance costs.

Reciprocating Piston Compressor

Piston laser cutter compressors have a long history of use and are currently the most commonly used compressors in China.

Due to its wide pressure range, it can adapt to a wide energy range, has advantages such as high speed, multi-cylinder, adjustable energy, high thermal efficiency, and is suitable for a variety of working conditions; its disadvantages are complex structure, many vulnerable parts, short maintenance cycle, sensitivity to wet stroke, pulse vibration, and poor running stability.

Application, Advantages and Disadvantages of Laser Cutter Compressor

Centrifugal Air Compressors

Centrifugal air compressors are suitable for large and medium flow, medium and low pressure occasions. They have compact structure, large exhaust volume range, balanced operation, reliable operation, high operation rate, and few friction parts. Therefore, less spare parts are required, and less maintenance costs and personnel are required.

Screw Air Compressors 

Screw air compressors have the advantages of simple structure, small size, no wearing parts, reliable operation, long life, and simple maintenance. However, they may not be as suitable as centrifugal air compressors in high pressure and large flow situations. They also require large maintenance and have high operating costs, and their energy-saving effect is not as good as that of centrifugal compressors.

Reciprocating Piston Compressors

Reciprocating piston compressors can produce higher exhaust pressures and are suitable for occasions requiring high-pressure gas. They are relatively simple in design and easy to maintain and repair. They can handle a variety of gases, including gas mixtures. However, due to the reciprocating motion of the piston, they may produce greater vibration and noise. Compared with other types of air compressors, they are larger in size.
Widely used in refrigeration, air conditioning, gas transportation, pneumatic tools, automobile maintenance and industrial gas compression.

Summary

When selecting a laser cutter compressor, comprehensive consideration should be given to specific application requirements, gas characteristics and economic efficiency.
