Working Principle
In the cutting-edge realm of air compression technology, achieving peak efficiency involves a keen understanding of the complex interplay between single-stage and multi-stage compression systems. Ideally, the energy demands of single-stage operations should seamlessly match those of their multi-stage counterparts. However, real-world conditions often necessitate additional power due to unavoidable factors such as transmission power losses, bearing friction, and the cooling effects caused by liquid viscosity. By skillfully reducing the compression ratio at each stage, multi-stage compression emerges as the epitome of efficiency, requiring notably less power compared to single-stage systems. This not only boosts overall system performance but also significantly curtails excessive energy use, establishing an unparalleled standard in power optimization.
Introducing the revolutionary Reliable 2024 Two-Stage Screw Compressor with Centrifugal Fan for Industries, a pinnacle of modern engineering excellence from Sanzhi (Henan) Compressor Co., Ltd. This cutting-edge machine boasts a sophisticated dual rotary screw mechanism; each stage is meticulously designed with an active screw driving a passive screw through a precisely engineered external power transfer system. The first stage features a low-pressure screw assembly, optimized for superior performance, while the second stage is crafted with a high-pressure screw assembly. Essential to this process are sealing air films around each screw, directing the compression process through three critical phases: the seamless intake of air, dynamic pressurization enhancing efficiency to unprecedented levels, and the final exhaust phase completing the cycle with remarkable precision.
First stage compression: The initiation of the two-stage screw air compressor's operation showcases engineering brilliance. A highly sophisticated low-pressure screw assembly takes charge, guiding gas into the compression chamber via a precisely crafted suction valve. As the rotor spins at a remarkable speed, the gas undergoes initial compression, setting the foundation for elevated compression in the subsequent phase.
Second stage compression: As the process advances to the second stage, the gas enters a uniquely engineered, more confined screw space, where pressures and temperatures are carefully elevated to extraordinary levels. The operation reaches a crucial juncture at the opening of the exhaust valve, allowing the high-pressure gases to exit the system, thereby completing the advanced compression cycle with unparalleled efficiency.
The intricate journey of air compression begins with ambient air effortlessly flowing through the air filter, blending with a trace of lubricating oil inside 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 progresses to the second-stage rotor, where it undergoes a secondary compression phase, reaching the intended final exhaust pressure. This meticulously orchestrated cycle concludes as the compressed gas is gracefully expelled through the exhaust valve, signifying the completion of a comprehensive and efficient air compression process.
