What is a Screw Compressor?
A screw compressor (or rotary screw air compressor) is a type of positive displacement compressor commonly used in heavy-duty industrial applications. It works by trapping air between two meshing helical screws and compressing it as it moves through the chamber. This mechanism ensures a continuous, reliable, and high-pressure air supply, making screw compressors ideal for large-scale operations.
To understand the science behind this mechanism, you can explore this detailed explanation on ScienceDirect – Screw Compressor.
How a Screw Compressor Works
Screw compressors operate with two rotors that rotate in opposite directions. As air is drawn into the chamber, it becomes compressed between the rotors and is pushed forward under high pressure. This continuous compression process makes screw compressors far more efficient than piston compressors for long-term industrial use.
There are two main types:
-
Dry-running Screw Compressors – Operate without oil, using timing gears to prevent contact between rotors.
-
Oil-flooded Screw Compressors – Use oil for sealing and cooling, perfect for demanding and heavy-duty industrial applications.
