Working Principle
In the cutting-edge realm of air compression, achieving unparalleled efficiency requires a deep understanding of the sophisticated interplay between single-stage and multi-stage compression systems. While the ideal scenario would see the energy demands of single-stage systems matching those of their multi-stage counterparts, real-world conditions often necessitate additional power due to inevitable factors such as transmission losses, bearing friction, and cooling impacts from liquid viscosity. By masterfully minimizing the compression ratio at each stage, multi-stage compression emerges as the zenith of efficiency, demanding far less power than single-stage alternatives. This strategy not only elevates overall system functionality but significantly curtails excess energy consumption, establishing a new gold standard in power optimization.
Introducing the revolutionary two-stage screw air compressor, a marvel of contemporary engineering prowess. This sophisticated machine is equipped with a cutting-edge dual rotary screw mechanism, where each stage boasts an active screw powering a passive screw through a meticulously crafted external power transfer system. The first stage features an advanced low-pressure screw assembly, engineered for peak performance, while the second stage is designed with a high-pressure screw assembly. Critical to this process is the presence of sealing air films enveloping each screw, guiding the compression journey through three pivotal phases: the seamless intake of air, dynamic pressurization that elevates efficiency to unprecedented levels, and the final exhaust phase that completes the cycle with unmatched accuracy.
First stage compression: The initiation of the two-stage screw air compressor's operation is a testament to engineering brilliance. A highly sophisticated low-pressure screw assembly spearheads the process, directing gas into the compression chamber via a precisely calibrated suction valve. As the rotor spins at an impressive pace, the gas undergoes initial compression, laying the groundwork for enhanced compression in the subsequent stage.
Second stage compression: As the process advances to the second stage, the gas enters a distinctively engineered, more compact screw chamber, where pressures and temperatures are meticulously elevated to exceptional levels. The cycle reaches a crucial juncture at the activation of the exhaust valve, allowing the 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 achieve intermediate pressure, followed by significant cooling through interaction with oil mist in the cooling channel. The cooled gas then progresses to the second-stage rotor, where it undergoes a secondary compression phase to achieve the intended final exhaust pressure. This meticulously orchestrated cycle reaches its zenith as the compressed gas is elegantly expelled through the exhaust valve, marking the completion of a comprehensive and highly efficient air compression process.
