Working Principle

In the realm of air compression excellence, the energy needed for single-stage pressure transmission ideally matches the combined energy demands of multi-stage compression. However, in practical applications, elements such as coupling power losses, bearing friction, and cooling effects from fluid viscosity result in increased power usage. By reducing the compression ratio at each stage, these inefficiencies are significantly minimized. Thus, the total power consumption for multi-stage compression is effectively lower than that of single-stage alternatives.

Embrace the future of air compression with our cutting-edge two-stage screw air compressor! Masterfully engineered with a modern twin-stage rotary screw mechanism, this groundbreaking system features an active screw in each stage, driving a passive screw via a robust external power transmission. Crafted for superior performance, the initial stage employs a low-pressure screw set, smoothly transitioning to a high-pressure screw set in the second phase. Each meticulously designed screw is safeguarded by a sealing air film. Embark on a journey of unparalleled efficiency as the gas experiences a dynamic tri-phase process: suction, pressurization, and exhaust, harmoniously working together to deliver exceptional compression results.

First Stage Compression: Experience the pinnacle of efficiency in the initial stage of our two-stage screw air compressor. Here, the gas is skillfully compressed using a low-pressure screw set. The process begins as the gas is drawn into the compression chamber through the suction valve. Witness the transformation as the screw rotor's rapid rotation compresses the gas, preparing it seamlessly for the transition to the second stage.

Second Stage Compression: Enhance your compression experience with the second stage screw set, where the gas undergoes further compression within a strategically confined screw space. This stage achieves heightened temperatures and pressures, culminating in a robust release through the exhaust valve. High-pressure gases are triumphantly expelled, completing the seamless compression cycle.

Natural air begins its journey by being carefully drawn through the air filter into the first compression stage, where it blends with a precise amount of lubricating oil. This enriched mixture is compressed to an intermediate pressure, then directed into a cooling channel, where the gas engages with an abundant oil mist, significantly reducing its temperature. As the cooled, compressed gas advances to the second-stage rotor, it undergoes its final compression to achieve the ultimate exhaust pressure. This sophisticated process concludes with the fully compressed gas exiting the system through the exhaust valve, effectively completing the compression cycle.
