Working Principle
In the innovative arena of air compression, maximizing efficiency involves mastering the intricate dynamics between single-stage and multi-stage compression systems. Ideally, the energy requirements for single-stage operations should align seamlessly with those of multi-stage systems. However, in reality, additional power is often required due to unavoidable elements such as transmission power losses, friction from bearings, and cooling effects induced by liquid viscosity. By expertly minimizing the compression ratio at each stage, multi-stage compression stands as the pinnacle of efficiency, requiring significantly less power than single-stage counterparts. This not only enhances overall system proficiency but dramatically reduces excess energy consumption, setting an unprecedented benchmark in power optimization.
Presenting the groundbreaking two-stage screw air compressor, a triumph of modern engineering. This advanced device features a state-of-the-art dual rotary screw mechanism; each stage flaunts an active screw driving a passive screw via a meticulously designed external power transfer system. The first stage is equipped with a low-pressure screw assembly, fine-tuned for optimal performance, while the second stage is crafted with a high-pressure screw assembly. Crucial to this process are sealing air films encasing each screw, guiding the compression journey through three essential phases: the smooth intake of air, dynamic pressurization elevating efficiency to new heights, and the final exhaust phase completing the cycle with unmatched precision.
First stage compression: The commencement of the two-stage screw air compressor's operation exemplifies engineering mastery. A highly advanced low-pressure screw assembly takes the lead, channeling gas into the compression chamber through a precisely engineered suction valve. As the rotor spins at an impressive velocity, the gas undergoes initial compression, setting the stage for enhanced compression in the upcoming phase.
Second stage compression: Upon transitioning to the second stage, the gas enters a uniquely engineered, more confined screw space, where pressures and temperatures are meticulously heightened to unparalleled levels. The process reaches a pivotal moment at the opening of the exhaust valve, allowing the high-pressure gases to exit the system, thus completing the sophisticated compression cycle with unmatched efficiency.
The sophisticated journey of air compression commences with ambient air smoothly passing through the air filter, mingling with a trace of lubricating oil within the compression chamber. This mixture undergoes initial compression to 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, achieving the desired final exhaust pressure. This meticulously orchestrated cycle culminates as the compressed gas is elegantly discharged through the exhaust valve, marking the completion of a comprehensive and efficient air compression process.
