What Is a Rotary Screw Air Compressor?
A rotary screw air compressor is a type of positive displacement compressor that uses two interlocking helical screws (rotors) to compress air. As the screws turn, the air is trapped between the rotors and the casing, decreasing its volume and increasing its pressure. This method of compression is highly efficient and reliable, making these air compressors ideal for continuous use in various industrial applications. They are commonly used in manufacturing, automotive, and construction industries due to their ability to deliver a consistent supply of compressed air.
How Does a Rotary Screw Compressor Work?
The operation of a rotary screw air compressor involves drawing air into the chamber through an inlet valve. As the rotors turn, they trap the air and move it along the screws, compressing it as the space between the screws and the chamber decreases. The compressed air is then pushed through an outlet valve and into a storage tank or directly to the point of use. The continuous cycle allows the compressor to provide a steady stream of compressed air, which is essential for applications that require a constant supply. The absence of valves and other mechanical parts that can wear out quickly contributes to the longevity and reliability of rotary screw air compressors.
