Introducing the revolutionary 250kw Energy-Efficient Water Cooling Two-Stage Screw Air Compressor by Sanzhi (Henan) Compressor Co., Ltd. This state-of-the-art technological marvel showcases an advanced dual rotary screw design, with each stage featuring an active screw driving a passive counterpart through a precisely engineered external power transfer system. The process kicks off with a low-pressure screw assembly, crafted for peak efficiency, followed by a high-pressure screw assembly, propelling operations to new heights. Central to this avant-garde process are the sealing air films encircling each screw, guiding compression through three pivotal phases: seamless intake, dynamic pressurization that elevates efficiency to unparalleled levels, and the precise exhaust phase, completing the cycle with unmatched mastery.
First Stage Compression: Embodying engineering excellence, the initial phase of the two-stage screw air compressor shines. A sophisticated low-pressure screw assembly takes center stage, skillfully directing gas into the compression chamber via a finely-tuned suction valve. As the rotor spins at remarkable speeds, the gas experiences initial compression, setting the stage for heightened compression in the next phase, thus priming the system for extraordinary performance and efficiency.
Second Stage Compression: In the second stage, the gas is expertly guided into a uniquely designed, compact screw space where pressure and temperature are elevated to extraordinary levels. This process reaches its peak as the exhaust valve opens, permitting high-pressure gases to exit the system, completing an intricate compression cycle epitomized by exceptional efficiency and sophistication.
The sophisticated air compression journey begins as ambient air smoothly flows through the air filter, merging with a touch of lubricating oil in the compression chamber. This blend undergoes initial compression to attain 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 reach the desired final exhaust pressure. This meticulously orchestrated cycle concludes as the compressed gas is elegantly expelled through the exhaust valve, marking the culmination of an exceptionally comprehensive and efficient air compression process.
