Working Principle
In the cutting-edge realm of air compression, the quest for supreme efficiency is a captivating dance between single-stage and multi-stage compression systems. Theoretically, the energy demands for single-stage operations should seamlessly mirror those of multi-stage systems. However, the practical landscape reveals that additional energy is often necessary due to inevitable factors such as transmission power losses, friction from bearings, and cooling effects induced by liquid viscosity. By skillfully minimizing the compression ratio at each stage, multi-stage compression emerges as the epitome of efficiency, requiring significantly less power compared to single-stage counterparts. This not only elevates overall system performance but also dramatically slashes unnecessary energy consumption, setting a groundbreaking benchmark in power optimization.
Introducing the revolutionary two-stage screw air compressor, a marvel of contemporary engineering excellence. This sophisticated machine boasts a cutting-edge dual rotary screw mechanism; each stage showcases an active screw driving a passive screw via a meticulously crafted external power transfer system. The first stage is outfitted with a low-pressure screw assembly, expertly tuned for peak performance, while the second stage is engineered with a high-pressure screw assembly. Pivotal to this process are sealing air films enveloping each screw, steering the compression journey through three vital phases: the seamless intake of air, dynamic pressurization elevating efficiency to unprecedented heights, and the final exhaust phase completing the cycle with unmatched precision.
First stage compression: The onset of the two-stage screw air compressor's operation exemplifies engineering prowess. An exceedingly advanced low-pressure screw assembly assumes the lead, directing gas into the compression chamber through a precisely crafted suction valve. As the rotor spins at an impressive velocity, the gas undergoes an initial compression, setting the stage for heightened compression in the subsequent phase.
Second stage compression: As the process transitions into the second stage, the gas enters a uniquely crafted, more confined screw space, where pressures and temperatures are meticulously augmented to unmatched levels. The operation reaches a critical juncture at the unveiling of the exhaust valve, allowing the high-pressure gases to exit the system, thus consummating the sophisticated compression cycle with unparalleled efficiency.
The refined journey of air compression begins with ambient air gracefully passing through the air filter, merging with a touch of lubricating oil within the compression chamber. This blend undergoes initial compression to 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 experiences a secondary compression phase, achieving the desired final exhaust pressure. This meticulously orchestrated cycle culminates as the compressed gas is elegantly released through the exhaust valve, marking the completion of a comprehensive and efficient air compression process.
