Revolutionary Working Principle: Ushering in a New Era of Air Compression
Pioneering the vanguard of air compression technology, we achieve unmatched efficiency by harmonizing single-stage and multi-stage systems. While theoretically similar in energy usage, real-world scenarios often necessitate additional energy due to factors like transmission power losses, bearing friction, and cooling effects. Multi-stage systems, by minimizing the compression ratio at each phase, reach exceptional efficiency, markedly reducing power consumption compared to single-stage systems. This innovative approach not only elevates system performance but also dramatically curtails extra energy utilization, establishing a new standard in power optimization.
Introducing the revolutionary 250kw Energy-Efficient Water Cooling Two-Stage Screw Air Compressor by Sanzhi (Henan) Compressor Co., Ltd. This cutting-edge marvel features a dual rotary screw mechanism, wherein each phase showcases an active screw driving a passive screw via a meticulously crafted external power transfer system. The first stage is equipped with a low-pressure screw assembly, fine-tuned for peak efficiency, while the second stage encompasses a high-pressure screw assembly. Central to this advanced process are sealing air films around each screw, guiding compression through three vital phases: seamless air intake, dynamic pressurization that propels efficiency to unparalleled heights, and the final exhaust phase, completing the cycle with exquisite precision and mastery.
First Stage Compression: The initiation phase of the two-stage screw air compressor exemplifies engineering brilliance. A sophisticated low-pressure screw assembly spearheads the process, channeling gas into the compression chamber through an exquisitely engineered suction valve. As the rotor spins at remarkable velocities, the gas undergoes initial compression, setting the premise for intensified compression in the subsequent phase, thereby priming the system for exceptional performance.
Second Stage Compression: Upon entering the second stage, the gas transitions into a uniquely designed, more confined screw space, where both pressure and temperature are meticulously elevated to unprecedented heights. This process peaks as the exhaust valve opens, permitting high-pressure gases to exit the system, marking the completion of an intricate compression cycle, characterized by unparalleled efficiency and sophistication.
The sophisticated air compression journey initiates as ambient air seamlessly navigates through the air filter, blending with a trace of lubricating oil within 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 advances to the second-stage rotor, encountering a secondary compression phase, achieving the desired final exhaust pressure. This meticulously orchestrated cycle culminates as the compressed gas is gracefully expelled through the exhaust valve, marking the conclusion of an exceptionally comprehensive and efficient air compression process.
