Embark on an exhilarating journey through the innovative realm of air compression technology with Sanzhi's latest pioneering model! Discover the remarkable energy efficiency of the sophisticated single-stage and multi-stage compression systems. Single-stage systems tackle issues such as transmission losses and friction efficiently. However, multi-stage compression triumphs by minimizing compression ratios at each phase, thereby significantly boosting efficiency and reducing power consumption. This meticulously engineered strategy not only enhances performance but also substantially decreases energy usage, setting an unparalleled benchmark in power efficiency.
Introducing the groundbreaking two-stage screw air compressor from Sanzhi (Henan) Compressor Co., Ltd. This engineering wonder showcases a dual rotary screw design, each stage driven by a brilliant external power transfer system. The first stage employs a cutting-edge low-pressure screw assembly, fine-tuned for optimal performance, followed by a high-pressure screw assembly. Air sealing films encircle each screw, directing compression through three crucial stages: smooth air intake, dynamic pressurization achieving outstanding efficiency, and a meticulously implemented exhaust phase.
First Stage Compression: Witness the commencement of the compression adventure with the innovative two-stage screw air compressor. This engineering marvel begins with a low-pressure screw assembly directing gas into the compression chamber through a masterfully crafted suction valve. As the rotor spins vigorously, the gas undergoes its initial compression, building a solid foundation for the intensified compression that follows in the subsequent stage.
Second Stage Compression: As the gas transitions to the second stage, it enters a uniquely crafted, compact screw chamber. Here, pressures and temperatures reach impressive heights, culminating at the cycle's zenith as the exhaust valve opens to release the high-pressure gases. This marks the pinnacle of the intricate compression cycle, executed with exceptional precision and efficiency.
The complex passage of air compression begins as ambient air effortlessly flows through the air filter, blending seamlessly with a whisper of lubricant within the compression chamber. This mixture 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, attaining the final exhaust pressure desired. This carefully orchestrated cycle concludes with the graceful expulsion of the compressed gas through the exhaust valve, marking the completion of a highly efficient and comprehensive air compression process.
