What is a screw air compressor?
Screw air compressor is a commonly used air compression equipment. It compresses air into the required high-pressure air through the working principle of a rotating screw. Screw air compressors usually consist of two screws that rotate in a closed compression chamber and compress air through the spiral shape and mutual meshing of the screws.
The working principle of a screw air compressor is as follows:
Air suction stage: Air enters through the suction port of the compressor, and the screw begins to rotate at the same time, sucking air into the spiral chamber.
Compression stage: When the screw rotates, the spiral-shaped blades gradually reduce the volume of the chamber, compressing the air and pushing it toward the outlet.
Exhaust stage: The compressed air is discharged from the outlet of the compressor. At this time, the air has reached the required high-pressure state.
Screw air compressors can be classified according to different criteria:
Classified by working principle:
Fixed speed screw air compressor: has fixed speed and output power.
Variable frequency screw air compressor: with adjustable speed and output power.
Classification by lubrication method:
Oil-lubricated screw air compressor: Uses oil lubrication and sealing to reduce wear and improve efficiency.
Oil-free screw air compressor: No oil lubrication is required, suitable for applications with high air quality requirements.
Classified by compression level:
Single-stage screw air compressor: There is only one stage in the compression process.
Two-stage screw air compressor: The compression process is divided into two consecutive stages.
Classified by compression ratio:
High-Pressure Screw Air Compressor: For applications requiring high-pressure output.
Low-Pressure Screw Air Compressor: For applications requiring low-pressure output.
