Working Principle
In the dynamic arena of air compression, achieving supreme efficiency requires a nuanced understanding of the interplay between single-stage and multi-stage compression systems. Ideally, single-stage energy demands would match those of multi-stage processes; however, practical challenges such as transmission power loss, bearing friction, and the cooling effects of liquid viscosity often necessitate ***. By precisely minimizing the compression ratio at each stage, multi-stage compression emerges as the epitome of efficiency, requiring markedly less power than single-stage models. This innovative approach not only boosts overall system efficiency but also significantly reduces excess energy consumption, setting a pioneering standard in power optimization.
Introducing the groundbreaking two-stage screw air compressor, an exquisite integration of state-of-the-art engineering. This advanced apparatus boasts a dual rotary screw system, each stage featuring an active screw that operates a passive screw via a finely engineered external power transfer system. The initial stage is equipped with a low-pressure screw assembly, meticulously optimized for top-tier performance, while the second stage is crafted with a high-pressure screw assembly. Central to this methodology are sealing air films surrounding each screw, guiding the compression process through three essential phases: the flawless air intake, the dynamic pressurization that enhances efficiency to unprecedented heights, and the final exhaust phase that concludes the cycle with remarkable accuracy.
First stage compression: The commencement of the two-stage screw air compressor's operation exemplifies engineering prowess. A sophisticated low-pressure screw assembly takes the spotlight, directing gas into the compression chamber through an intricately designed suction valve. With the rotor spinning at remarkable speed, the gas undergoes initial compression, laying the groundwork for the advanced compression stage that follows.
Second stage compression: As the gas progresses to the second stage, it is introduced to a specially engineered, more confined screw chamber, where pressures and temperatures are expertly elevated to unparalleled levels. The process reaches its climax at the exhaust valve opening, a crucial juncture that allows the high-pressure gases to exit the system, thereby completing the advanced compression cycle with exceptional efficiency.
The sophisticated air compression journey commences with ambient air seamlessly flowing through the air filter, where it merges with a trace of lubricating oil inside the compression chamber. This blend undergoes an initial compression to intermediate pressure, then experiences substantial cooling through interaction with oil mist within the cooling channel. The cooled gas progresses to the second-stage rotor, undergoing a secondary compression phase to reach the target final exhaust pressure. This meticulously coordinated cycle peaks as the compressed gas is elegantly released through the exhaust valve, marking the conclusion of a comprehensive and efficient air compression process.
