Embark on an exciting journey into the world of air compression technology with Sanzhi's latest pioneering creation! Discover the extraordinary energy efficiency of cutting-edge single-stage and multi-stage compression systems. While single-stage systems tackle issues like transmission losses and friction, multi-stage compression surpasses them by reducing compression ratios at each stage, significantly boosting efficiency and lowering power consumption. This thoughtfully engineered strategy not only elevates performance but also dramatically reduces energy usage, setting a new benchmark in power efficiency.
Introducing the revolutionary two-stage screw air compressor by Sanzhi (Henan) Compressor Co., Ltd. This engineering marvel boasts a dual rotary screw design with each stage powered by a brilliant external power transfer mechanism. The initial stage employs a cutting-edge low-pressure screw assembly optimized for superior performance, followed by a high-pressure screw assembly. Air films precisely seal around each screw, guiding the compression through three crucial phases: seamless air intake, dynamic pressurization for unmatched efficiency, and a carefully executed exhaust phase.
First Stage Compression: Experience the beginning of the compression journey with the innovative two-stage screw air compressor. This technological wonder commences with a low-pressure screw assembly that channels gas into the compression chamber through a skillfully engineered suction valve. As the rotor spins vigorously, the gas undergoes its initial compression, setting a strong foundation for the intensified compression in the following stage.
Second Stage Compression: As the gas transitions to the second stage, it enters a specially designed, compact screw chamber. Here, pressure and temperature reach impressive heights, culminating in the cycle as the exhaust valve opens, releasing the high-pressure gases. This marks the completion of the sophisticated compression cycle, executed with exceptional precision and efficiency.
The intricate journey of air compression begins as ambient air effortlessly flows through the air filter, seamlessly merging with a hint of lubricant within the compression chamber. This blend undergoes initial compression to an intermediate pressure, followed by significant cooling via oil mist interactions in the cooling channel. The cooled gas then advances to the second-stage rotor for secondary compression, reaching the desired final exhaust pressure. This meticulously orchestrated cycle concludes with the graceful release of the compressed gas through the exhaust valve, marking the end of a highly efficient and comprehensive air compression process.
