Through precise calibration of the compression ratio at each stage, multi-stage systems achieve remarkable efficiency, drastically reducing power consumption compared to single-stage systems. This refined approach not only enhances overall system performance but also significantly curtails excess energy use, establishing a revolutionary benchmark in power optimization.
Introducing the groundbreaking 250kw Energy-Efficient Water Cooling Two-Stage Screw Air Compressor by Sanzhi (Henan) Compressor Co., Ltd. This state-of-the-art technological masterpiece features a sophisticated dual rotary screw configuration, where each stage hosts an active screw driving a passive counterpart via a meticulously engineered external power transfer mechanism. The initial stage is governed by a low-pressure screw assembly, optimized for peak efficiency, followed by a high-pressure screw assembly in the subsequent phase. Integral to this advanced mechanism are the sealing air films encompassing each screw, steering compression through three pivotal phases: smooth intake, dynamic pressurization that elevates efficiency to extraordinary heights, and a precise exhaust phase, completing the cycle with unmatched precision.
First Stage Compression: The initial phase of the two-stage screw air compressor stands as a testament to exceptional engineering prowess. A finely-tuned low-pressure screw assembly takes the lead, guiding gas into the compression chamber through an expertly designed suction valve. As the rotor spins at impressive speeds, the gas undergoes preliminary compression, setting the stage for enhanced compression in the subsequent phase, thereby priming the system for outstanding performance and efficiency.
Second Stage Compression: As the process progresses to the second stage, the gas is adeptly maneuvered into a uniquely compact screw space where both pressure and temperature are strategically elevated to extraordinary levels. This phase reaches its apex as the exhaust valve opens, allowing high-pressure gases to exit the system, concluding an intricate compression cycle characterized by remarkable efficiency and sophistication.
The sophisticated air compression journey commences with ambient air flowing effortlessly through the air filter, merging seamlessly with a hint of lubricating oil in the compression chamber. This blend undergoes initial compression to reach 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, undergoing a secondary compression phase to achieve the desired final exhaust pressure. This meticulously orchestrated cycle culminates as the compressed gas is elegantly expelled through the exhaust valve, marking the completion of an exceptionally thorough and efficient air compression process.
