Working Principle
Embark on an enthralling expedition into the forefront of air compression technology with Sanzhi's groundbreaking innovation! This is your exclusive gateway to unmatched energy efficiency, transforming your exploration into an exhilarating adventure, courtesy of the sophisticated dynamics of single-stage and multi-stage compression systems. Single-stage systems strive to achieve efficiency akin to multi-stage systems but encounter challenges such as transmission losses, bearing friction, and cooling effects due to liquid viscosity, necessitating innovative solutions. Multi-stage compression, by elegantly reducing the compression ratio at each stage, stands as the epitome of efficiency, utilizing significantly less power than single-stage systems. This expertly developed approach not only bolsters the system's overall performance but also dramatically curtails energy consumption, setting a revolutionary benchmark in power optimization and efficiency.
Introducing the revolutionary two-stage screw air compressor from Sanzhi (Henan) Compressor Co., Ltd. - a true marvel of modern engineering prowess. This advanced device boasts an innovative dual rotary screw design, where each stage features an active screw driving a passive counterpart via a meticulously crafted external power transfer mechanism. The initial stage is equipped with a cutting-edge low-pressure screw assembly, perfectly attuned for optimal performance, while the subsequent stage features a high-pressure screw assembly. At the core of this process are sealing air films enveloping each screw, orchestrating the compression through three vital phases: seamless air intake, dynamic pressurization elevating efficiency to new heights, and culminating in an exhaust phase executed with exceptional precision.
First Stage Compression: Behold the commencement of the two-stage screw air compressor process, a marvel of intricate engineering sophistication. It starts with a trailblazing low-pressure screw assembly that channels gas into the compression chamber through a meticulously calibrated suction valve. As the rotor spins with impressive speed, the gas undergoes its initial compression, laying a robust groundwork for the intensified compression that follows in the next stage.
Second Stage Compression: As the gas progresses into the second stage, it enters an ingeniously engineered, more compact screw chamber. Here, pressures and temperatures are systematically elevated to extraordinary levels, reaching the cycle's zenith as the exhaust valve activates, allowing high-pressure gases to be released. This marks the culmination of the intricate compression cycle, executed with extraordinary efficiency and precision.
The sophisticated air compression journey unfolds as ambient air glides effortlessly through the air filter, seamlessly merging with a touch of lubricating oil within the compression chamber. This mixture undergoes initial compression to an 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 undergoes a secondary compression phase to reach the final desired exhaust pressure. This intricately coordinated cycle concludes as the compressed gas is smoothly expelled through the exhaust valve, marking the completion of a comprehensive and highly efficient air compression process.
