Rotary Screw Air Compressor
Gem Air Compressor (India) Private Limited offers Rotary Screw Air Compressor. Rotary air compressors are positive displacement compressors. The most common rotary air compressor is the single stage helical or curved lobe oil flooded screw air compressor. These compressors consist of two rotors within a casing where the rotors compress the air internally. There are no valves. These units are principally oil cooled (with air cooled or water cooled oil coolers) where the oil seals the internal clearances. Since the cooling takes place right inside the compressor, the working parts never experience extreme operating temperatures. The rotary compressor, therefore, is a continuous duty, air cooled or water cooled compressor package. Rotary screw air compressors are easy to keep up and operate. Capacity control for these compressors is proficient by variable speed and variable compressor displacement. For the latter control technique, a slide valve is positioned in the casing. As the compressor capacity is reduced, the slide valve opens, bypassing a portion of the compressed air back to the suction. Advantages of the rotary screw compressor include smooth, pulse-free air output in a compact size with high output volume over a long life.
- Asymmetrical, 5 lobe 6 flutes rotor profile machined to the highest accuracy not only ensures reduced differential pressure between lobe and flute, but also assures lowest possible backflow. Adibatic efficiency is increased by 10912%. which translates into 25% energy saving as compared to the 4 lobel 6 flutes rotor profile.
