The difference between scroll and screw compressor

Scroll air compressor and screw air compressor are all volumetric rotary compressors.

The scroll air compressor has no reciprocating mechanism, so it has simple structure, small size, light weight and few parts.

Screw air compressor has the following advantages:

1. High reliability. Screw compressor parts less, no wearing parts, so it is reliable operation;

2, long life, overhaul interval up to 4-80000 hours;

3. Convenient operation and maintenance. The screw compressor has a high degree of automation, and the operator does not have to go through a long period of professional training, and can realize unattended operation;

4, the power balance is good. The screw compressor has no unbalanced inertial force, the machine can work smoothly at high speed, and can realize no-foundation operation. It is especially suitable for mobile compressors with small size, light weight and less floor space. The scroll air compressor uses the meshing of the rotor and the stator to form a plurality of compression chambers. With the translation and rotation of the rotor, the volume of each compression chamber is constantly changing to realize the suction and compression of gas; while the screw air compressor compresses the air It is achieved by the volume change of the tooth grooves of the male and female rotors meshing in parallel in the casing.
