Introducing the groundbreaking 250kw Energy-Efficient Water Cooling Two-Stage Screw Air Compressor by Sanzhi (Henan) Compressor Co., Ltd. This technological masterpiece is equipped with a sophisticated dual rotary screw design, where each stage features an active screw propelling a passive counterpart via an expertly crafted external power transfer mechanism. The initial stage features a low-pressure screw assembly, optimized for peak efficiency, succeeded by a high-pressure screw assembly in the next phase. Essential to this advanced mechanism are the sealing air films surrounding each screw, directing compression through three critical phases: smooth intake, dynamic pressurization that elevates efficiency to new heights, and a precise exhaust phase, completing an unparalleled cycle.
First Stage Compression: The initial phase of the two-stage screw air compressor exemplifies supreme engineering. A precisely tuned low-pressure screw assembly leads the way, drawing gas into the compression chamber through a meticulously 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, thus preparing the system for exceptional performance and efficiency.
Second Stage Compression: As the process progresses to the second stage, the gas is deftly guided into a uniquely compact screw space where both pressure and temperature are strategically elevated to extraordinary levels. This phase reaches its zenith 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 begins as ambient air flows effortlessly through the air filter, blending seamlessly with a hint of lubricating oil in the compression chamber. This mixture undergoes initial compression to reach intermediate pressure, followed by substantial cooling through interaction with oil mist in the cooling channel. The cooled gas then advances to the second-stage rotor, experiencing 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 exquisitely thorough and efficient air compression process.
