Working Principle
In the forefront of air compression innovation, the quest for ultimate efficiency elegantly balances between single-stage and multi-stage compression systems. While theoretically, the energy requirements for single-stage should align with multi-stage systems, the practical world necessitates extra energy due to unavoidable elements like transmission power losses, bearing friction, and cooling effects from liquid viscosity. By adeptly reducing the compression ratio at each phase, multi-stage compression becomes the pinnacle of efficiency, demanding substantially less power than single-stage systems. This not only enhances the overall system performance but dramatically reduces unnecessary energy usage, setting a revolutionary standard in power efficiency.
Introducing the groundbreaking two-stage screw air compressor, a masterpiece of modern engineering excellence. This sophisticated apparatus features a state-of-the-art dual rotary screw mechanism; each stage is equipped with an active screw driving a passive screw through a precisely engineered external power transfer system. The first stage is fitted with a low-pressure screw assembly, finely tuned for optimal performance, while the second stage houses a high-pressure screw assembly. Central to this process are sealing air films around each screw, guiding the compression journey through three key phases: seamless air intake, dynamic pressurization lifting efficiency to new heights, and the final exhaust phase completing the cycle with exceptional precision.
First stage compression: The initiation of the two-stage screw air compressor's operation exemplifies engineering mastery. An ultra-advanced low-pressure screw assembly takes charge, channeling gas into the compression chamber via a meticulously crafted suction valve. As the rotor spins at a remarkable speed, the gas undergoes an initial compression, setting the groundwork for enhanced compression in the subsequent stage.
Second stage compression: Transitioning into the second stage, the gas enters a specially designed, more confined screw space, where pressures and temperatures are carefully elevated to unprecedented levels. The process reaches a critical point as the exhaust valve opens, allowing high-pressure gases to exit, thus completing the sophisticated compression cycle with unparalleled efficiency.
The refined process of air compression begins with ambient air gracefully flowing through the air filter, meeting a trace of lubricating oil within the compression chamber. This mixture 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 conclusion of a comprehensive and efficient air compression process.
