Unveiling 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 features a groundbreaking dual rotary screw design. Each stage showcases an active screw driving a passive counterpart via a meticulously engineered external power transfer mechanism. The first stage is led by a low-pressure screw assembly, optimized for peak efficiency, followed by a high-pressure screw assembly in the subsequent phase. Central to this avant-garde process are the sealing air films enveloping each screw, guiding compression through three crucial phases: seamless intake, dynamic pressurization that propels efficiency to unparalleled heights, and a precise exhaust phase, completing the cycle with unmatched mastery.
First Stage Compression: The initial phase of the two-stage screw air compressor stands as a testament to engineering brilliance. A sophisticated low-pressure screw assembly takes center stage, expertly directing gas into the compression chamber via a precisely engineered suction valve. As the rotor accelerates to astounding speeds, the gas undergoes initial compression, setting the groundwork for intensified compression in the ensuing phase, thereby equipping the system for exceptional performance and efficiency.
Second Stage Compression: Upon entering the second stage, the gas is channeled into a uniquely designed, more compact screw space where both pressure and temperature are meticulously elevated to remarkable levels. This process reaches its culmination as the exhaust valve opens, allowing high-pressure gases to exit the system, completing an intricate compression cycle characterized by unparalleled efficiency and sophistication.
Embark on a sophisticated air compression journey as ambient air effortlessly flows through the air filter, merging with a hint of lubricating oil within the compression chamber. This amalgamation undergoes initial compression to achieve intermediate pressure, followed by significant cooling through interaction with oil mist in the cooling channel. The cooled gas then progresses to the second-stage rotor, experiencing a secondary compression phase to attain 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.
