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.

The oil free rotary screw air compressor utilizes specially designed air ends to compress air without oil in the compression chamber yielding true oil free air. Oil free rotary screw air compressors are available air cooled and water cooled and provides the same flexibility as oil flooded rotaries when oil free air is required.

Features

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.

High Precision Machining Equipments

Highly specialized, most advanced machining and control equipments enable rotor macining/grinding accurancy to 0.005mm, with roughness allowance (Ra)) of 0.1~0.2 u m.ation and bending stress of the air-end.

 Outstanding Design

Large in size , with low running rpm, Fusheng screw air-ends are more efficient and deliver more compressed air for the same driving power, Bearing design life can be assured by minimum vibration and bending stress of the air-end.
