Working Principle
In the cutting-edge realm of air compression, achieving unparalleled efficiency requires an insightful grasp of the sophisticated interplay between single-stage and multi-stage compression systems. While ideally single-stage systems would align energetically with their multi-stage counterparts, real-world conditions necessitate additional power due to factors like transmission losses, bearing friction, and cooling impacts from liquid viscosity. By expertly minimizing the compression ratio at each stage, multi-stage compression represents the pinnacle of efficiency, demanding significantly less power than single-stage alternatives. This strategic approach not only elevates overall system functionality but substantially reduces excess energy consumption, setting a new gold standard in power optimization.
Introducing the revolutionary two-stage screw air compressor-a beacon of contemporary engineering prowess. This sophisticated machine features a state-of-the-art dual rotary screw mechanism, where each stage boasts an active screw driving a passive screw via a meticulously designed external power transfer system. The first stage is equipped with an advanced low-pressure screw assembly, engineered for optimal performance, while the second stage is designed with a high-pressure screw assembly. Central to this process are sealing air films encasing each screw, guiding the compression journey through three pivotal phases: the seamless intake of air, dynamic pressurization elevating efficiency to unprecedented levels, and the final exhaust phase that concludes the cycle with unmatched precision.
First stage compression: The initiation of the two-stage screw air compressor's operation is a testament to engineering brilliance. A sophisticated low-pressure screw assembly spearheads the process, channeling gas into the compression chamber via a precisely calibrated suction valve. As the rotor spins at an impressive pace, the gas undergoes initial compression, setting the stage for enhanced compression in the subsequent stage.
Second stage compression: As the process advances to the second stage, the gas enters a distinctly engineered, more compact screw chamber, where pressures and temperatures are meticulously elevated to exceptional levels. The cycle reaches a crucial juncture with the activation of the exhaust valve, allowing high-pressure gases to exit the system, thereby concluding the intricate compression cycle with unparalleled efficiency.
The intricate journey of air compression begins as ambient air seamlessly passes through the air filter, merging with a hint of lubricating oil within the compression chamber. This mixture undergoes initial compression to reach 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, where it undergoes secondary compression to achieve 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.
