Working Principle
Venturing into the progressive world of air compression, achieving supreme efficiency demands an intricate understanding of the nuanced dynamics between single-stage and multi-stage compression systems. Ideally, single-stage systems would match the energy efficiency of multi-stage systems; however, real-world challenges such as transmission losses, bearing friction, and cooling impacts from liquid viscosity often require additional power. By skillfully reducing the compression ratio at each stage, multi-stage compression stands as the pinnacle of efficiency, requiring substantially less power than single-stage counterparts. This approach not only enhances overall system performance but also significantly reduces surplus energy consumption, setting a new benchmark in power optimization.
Introducing the groundbreaking two-stage screw air compressor, a testament to modern engineering excellence. This advanced apparatus features a state-of-the-art dual rotary screw design, with each stage employing an active screw that drives a passive screw via a precisely engineered external power transfer mechanism. The first stage is equipped with an advanced low-pressure screw assembly, optimized for superior performance, while the second stage incorporates a high-pressure screw assembly. Central to this process are sealing air films that surround each screw, guiding the compression through three critical phases: the seamless intake of air, dynamic pressurization that elevates efficiency to new heights, and the final exhaust phase which concludes the cycle with unmatched precision.
First Stage Compression: The commencement of the two-stage screw air compressor's operation exemplifies engineering ingenuity. A highly advanced low-pressure screw assembly initiates the process, channeling gas into the compression chamber through a meticulously calibrated suction valve. As the rotor rotates at an impressive speed, the gas undergoes initial compression, setting the stage for further compression in the subsequent stage.
Second Stage Compression: Advancing to the second stage, the gas enters a distinctively engineered, more compact screw chamber, where pressures and temperatures are carefully elevated to exceptional levels. The cycle reaches a pivotal point with the activation of the exhaust valve, allowing the high-pressure gases to exit, thus concluding the intricate compression cycle with unparalleled efficiency.
The intricate journey of air compression commences as ambient air gently traverses through the air filter, blending with a trace of lubricating oil within the compression chamber. This mixture undergoes initial compression to achieve intermediate pressure, followed by substantial cooling through interaction with oil mist in the cooling channel. The cooled gas then advances to the second-stage rotor, where it experiences a secondary compression phase to reach the intended final exhaust pressure. This meticulously orchestrated cycle culminates as the compressed gas is elegantly expelled through the exhaust valve, marking the completion of a comprehensive and highly efficient air compression process.
