Introducing the revolutionary 250kw Energy-Efficient Water Cooling Two-Stage Screw Air Compressor by Sanzhi (Henan) Compressor Co., Ltd. This cutting-edge technological masterpiece boasts a sophisticated dual rotary screw setup, where each stage features an active screw driving a passive counterpart through a meticulously crafted external power transfer mechanism. The first stage is governed by a low-pressure screw assembly optimized for peak efficiency, followed by a high-pressure screw assembly in the next phase. Central to this advanced system are the sealing air films enveloping each screw, guiding compression through three crucial phases: effortless intake, dynamic pressurization that elevates efficiency to new heights, and a precision exhaust phase, completing the cycle with unparalleled accuracy.
First Stage Compression: The initial phase of the two-stage screw air compressor stands as a testament to superior engineering. A finely-tuned low-pressure screw assembly takes the lead, guiding gas into the compression chamber through a masterfully designed suction valve. As the rotor spins at impressive speeds, the gas undergoes initial compression, setting the stage for heightened compression in the subsequent phase, thereby preparing the system for extraordinary performance and efficiency.
Second Stage Compression: As the process advances to the second stage, the gas is expertly navigated into a uniquely compact screw space where both pressure and temperature are strategically heightened to extraordinary levels. This phase reaches its pinnacle as the exhaust valve opens, allowing high-pressure gases to exit the system, culminating an intricate compression cycle characterized by remarkable efficiency and sophistication.
The sophisticated air compression journey begins with ambient air effortlessly flowing through the air filter, seamlessly merging with a trace of lubricating oil in the compression chamber. This blend undergoes initial compression to reach intermediate pressure, followed by substantial cooling through interaction with oil mist in the cooling channel. The cooled gas then progresses 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.
