By expertly minimizing the compression ratio at each stage, our multi-stage systems accomplish remarkable efficiency and substantially reduce energy consumption compared to single-stage systems. This advanced methodology not only boosts system performance but also dramatically decreases energy waste, defining a revolutionary pinnacle in power efficiency.
Introducing the state-of-the-art 250kw Energy-Efficient Water Cooling Two-Stage Screw Air Compressor by Sanzhi (Henan) Compressor Co., Ltd. This technological masterpiece features an innovative dual rotary screw mechanism, where each stage includes an active screw driving a passive one through an expertly crafted external power transfer system. The first stage consists of a low-pressure screw assembly fine-tuned for superior performance, while the subsequent stage contains a high-pressure screw assembly. Essential to this complex operation are sealing air films encasing each screw, guiding compression through three pivotal phases: effortless air intake, dynamic pressurization boosting efficiency to extraordinary levels, and the final exhaust stage, completing the cycle with unmatched precision and excellence.
First Stage Compression: The initial stage of the two-stage screw air compressor stands as a testament to engineering excellence. A complex low-pressure screw assembly initiates the process, channeling gas into the compression chamber through a precisely engineered suction valve. As the rotor spins at impressive velocities, the gas undergoes initial compression, laying the foundation for heightened compression in the subsequent stage, thereby setting the stage for exceptional system performance.
Second Stage Compression: As the gas transitions into the second stage, it enters a meticulously designed, more confined screw space where both pressure and temperature are expertly elevated to new levels. This process reaches its pinnacle as the exhaust valve opens, allowing high-pressure gases to exit the system seamlessly, completing an intricate compression cycle marked by unrivaled efficiency and sophistication.
The sophisticated air compression journey begins as ambient air smoothly navigates through the air filter, merging with a touch of lubricating oil within the compression chamber. This blend undergoes initial compression to intermediate pressure, then experiences substantial cooling through interaction with oil mist in the cooling channel. The cooled gas advances to the second-stage rotor, facing a secondary compression phase to achieve the desired final exhaust pressure. This meticulously orchestrated cycle concludes as the compressed gas is elegantly discharged through the exhaust valve, marking the end of an exceptionally comprehensive and efficient air compression process.
