Description

Due to the high temperature generated by the high-speed operation in the gas compression, the dry compression requires cooling measures to ensure that the shape of the body does not change. Therefore, the compressor casing is designed with a double-wall structure, and the interlayer is used for cooling liquid (air-cooled unit) or Cooling water (water-cooled unit) circulates to cool the compressor. In the compression chamber, the hot air is compressed and discharged through the rotation of the twin-screw, and the compressed air is discharged after being cooled by the air cooler.
A cooling channel is designed on the outside of the compression chamber, and the heat of the compression chamber is taken away through the circulation of cooling oil (air-cooled type) or cooling water (water-cooled type), so that the working temperature of the compression chamber can be effectively controlled and the service life of the rotor coating is improved.
The rotor adopts a newly designed rotor patent profile, and after more than 20 processes of finishing, the accuracy and reliability of the rotor profile are guaranteed.

Dry Oil-free Screw Air Compressor Manufacturer and Supplier

Oil-free screw air compressors are widely used in medicine, food, electronics, chemical industry, packaging and other industries that require high-quality air sources. 100% pure compressed air is a necessary measure to ensure the process and product quality. You can risk-free, Safely produce your high-end products. The lubrication system of the oil-free screw air compressor is a separate oil supply circulation unit. The compression chamber and the bearing are tightly separated by high-performance mechanical seal components. The lubricating oil can only flow in its closed area and cannot enter the compression chamber. The compression chamber is pure air that does not contain, and after a little post-treatment of water removal and dust removal, 100% pure compressed air can be obtained.
