Working Principle
Embark on an exhilarating journey into the cutting-edge realm of air compression technology with Sanzhi's groundbreaking innovation! Discover a world where energy efficiency reaches new heights, transforming every exploration into an exciting adventure within the advanced dynamics of both single-stage and multi-stage compression systems. While single-stage systems endeavor to match the efficiency of their multi-stage counterparts, they encounter challenges such as transmission losses, bearing friction, and cooling effects from liquid viscosity, demanding innovative solutions. Multi-stage compression, by ingeniously reducing the compression ratio at each stage, represents the zenith of efficiency, requiring markedly less power than single-stage systems. This expertly engineered method not only elevates system performance but also significantly curtails energy consumption, establishing a revolutionary standard in power optimization and efficiency.
Introducing the groundbreaking two-stage screw air compressor from Sanzhi (Henan) Compressor Co., Ltd. - a testament to modern engineering brilliance. This advanced apparatus boasts an innovative dual rotary screw design, where each stage features an active screw driving a passive counterpart via a meticulously designed external power transfer mechanism. The initial stage is equipped with a state-of-the-art low-pressure screw assembly, finely tuned for optimal performance, while the subsequent stage incorporates a high-pressure screw assembly. At the heart of this process are sealing air films encircling each screw, orchestrating the compression through three vital phases: impeccable air intake, dynamic pressurization that elevates efficiency to unprecedented heights, and culminating in an exhaust phase performed with exceptional precision.
First Stage Compression: Delve into the commencement of the two-stage screw air compressor process, an embodiment of exquisite engineering sophistication. It begins with an innovative low-pressure screw assembly that channels gas into the compression chamber through a meticulously calibrated suction valve. As the rotor spins with velocity, the gas undergoes its initial compression, establishing a solid foundation for the intensified compression that unfolds in the subsequent stage.
Second Stage Compression: As the gas advances into the second stage, it enters a uniquely engineered, more compact screw chamber. Here, pressures and temperatures are systematically elevated to exceptional levels, reaching the cycle's pinnacle as the exhaust valve activates, releasing high-pressure gases. This marks the completion of the intricate compression cycle, executed with extraordinary efficiency and precision.
The sophisticated journey of air compression unfolds as ambient air glides effortlessly through the air filter, seamlessly merging with a trace of lubricating oil within the compression chamber. This blend undergoes initial compression to an 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 to achieve the desired final exhaust pressure. This intricately orchestrated cycle concludes as the compressed gas is elegantly expelled through the exhaust valve, signifying the completion of a comprehensive and highly efficient air compression process.
