Working Principle
Venturing into the cutting-edge realm of air compression, achieving unparalleled efficiency necessitates a deep dive into the sophisticated interplay between single-stage and multi-stage compression systems. While ideally, single-stage systems would rival multi-stage systems in energy efficiency, real-world obstacles like transmission losses, bearing friction, and cooling impacts from liquid viscosity often demand additional energy input. Multi-stage compression ingeniously minimizes the compression ratio at each stage, emerging as the apex of efficiency with significantly lower power requirements compared to single-stage systems. This method not only augments overall system performance but also dramatically curtails excess energy usage, establishing a new standard in power optimization.
Introducing our revolutionary two-stage screw air compressor, a beacon of contemporary engineering excellence. This state-of-the-art device boasts a dual rotary screw design, with each stage harnessing an active screw to drive a passive screw through a meticulously crafted external power transfer mechanism. The first stage features a sophisticated low-pressure screw assembly, fine-tuned for peak performance, while the second stage includes a high-pressure screw assembly. Key to this process are sealing air films enveloping each screw, directing the compression through three essential phases: the flawless intake of air, dynamic pressurization that elevates efficiency to unprecedented levels, and the final exhaust phase that concludes the cycle with unparalleled precision.
First Stage Compression: The initiation of the two-stage screw air compressor's operation showcases engineering brilliance. An exceptionally advanced low-pressure screw assembly begins the process, directing gas into the compression chamber via a precisely calibrated suction valve. As the rotor spins at impressive speeds, the gas undergoes initial compression, setting the foundation for the subsequent stage's further compression.
Second Stage Compression: Progressing to the second stage, the gas enters a uniquely crafted, more compact screw chamber, where pressures and temperatures are expertly elevated to extraordinary levels. The cycle peaks with the activation of the exhaust valve, allowing the high-pressure gases to exit, thus completing the intricate compression cycle with unrivaled efficiency.
The intricate journey of air compression begins as ambient air gently traverses the air filter, merging with a trace of lubricating oil within the compression chamber. This blend undergoes initial compression to attain intermediate pressure, followed by significant cooling through interaction with oil mist in the cooling channel. The cooled gas then advances to the second-stage rotor, experiencing a secondary compression phase to reach the desired final exhaust pressure. This meticulously orchestrated cycle culminates as the compressed gas is elegantly expelled through the exhaust valve, marking the end of a comprehensive and highly efficient air compression process.
