Comparison of oil-free screw air compressor and oil-free scroll air compressor

Manufacturers who need compressors often cannot tell the difference between oil-free screw air compressors and oil-free scroll air compressors. In fact, there are many similarities and differences between screw machine and scroll machine. The following granklin water lubricated air compressor manufacturers compare and distinguish through working principle, detailed comparison data, advantages and application scenarios.

1. Working principle

the scroll air compressor is a movable scroll that rotates around the center of the base circle of the fixed scroll, and the two mesh with each other to realize the process of suction, compression and exhaust. (as shown below)

the screw air compressor compresses the air by means of the volume change of the tooth grooves of the male and female rotors meshing in parallel with each other in the casing to achieve the purpose of compressing the air. (as shown below)

2. Application comparison

screw air compressor is widely used in machinery, metallurgy, electronic power, chemical industry, mining, textile, transportation and many other industrial fields.

Now the water-lubricated air compressor produced by granklin Group is also widely used in hospitals, pharmaceuticals, food, beverages, wineries, laboratories and other scenarios. granklin has solved a series of air compression problems on single screw air compressors.

scroll machine is mainly used in hospitals, pharmaceuticals, food, beverages, wineries, laboratories and other places with high noise and vibration requirements, which is directly related to the characteristics of scroll machine silence and compressed air oil-free.

According to the above principle, the oil-free scroll air compressor is characterized by no metal friction in the compression chamber, low noise and long life of the compressor. However, it is obvious that the oil-free scroll air compressor has high machining accuracy and high production technology requirements.

From the above technical comparison, it can be seen that the water-lubricated air compressor produced by Granklin Group has better effect, oil-free air compression is more stable, and the maintenance of the whole machine is more convenient.
