Water-lubricated Oil-free Air Compressor Working Principle

Working Principle of Water-Lubricated Oil-Free Screw Air Compressor:

1. Intake process:

The outside air enters the air inlet of the air compressor through the intake filter.

Near the air intake is a set of impellers that rotate to supercharge the air and feed it into the oil free screw air compressor.

2. Compression stage:

The air is directed to the oil free screw compressor. The oil free screw compressor is composed of two screws (one fixed and one movable).

When the screw is running, the movable screw achieves air compression with the help of the fixed screw.

3. Cooling stage:

The compressed air becomes hot and needs to be cooled by a cooling system.

A common way to do this is to use a water cooling system, in which water is circulated through a cooling pipe to help cool the compressed air.

4. Separation and drying:

The cooled air passes through a separator to separate the water and oil.

Moisture is then further removed from the air by drying systems, such as adsorption or condensing dryers.

5. Emission stage:

The dry, oil-free air after the final treatment is stored in a compressed air container for subsequent application scenarios.

Inside the container, there are usually discharge valves that release air into the service system as needed.

Through the above process, water-lubricated oil-free screw air compressors provide clean, efficient compressed air and are suitable for applications with high air quality requirements.
