Working Principle
Pioneering a new era in air compression technology, Sanzhi (Henan) Compressor Co., Ltd. stands at the cutting-edge, redefining excellence with its unparalleled efficiency in air compression systems. By ingeniously combining the strengths of both single-stage and multi-stage systems, Sanzhi adeptly tackles challenges like transmission power losses, bearing friction, and the cooling demands related to viscosity, which typically require extra energy. By meticulously perfecting compression ratios at every stage, Sanzhi's multi-stage systems showcase extraordinary efficiency, demanding significantly less power compared to their single-stage counterparts. This groundbreaking innovation not only elevates system performance but also drastically reduces energy consumption, establishing Sanzhi as a pioneer in the realm of power-efficient solutions.
Introducing the groundbreaking two-stage screw air compressor - a triumph of modern engineering brilliance. This exceptional device features a cutting-edge dual rotary screw mechanism, with each stage equipped with a dynamic active screw, driving a passive screw via a carefully crafted external power transfer system. The initial stage features a precisely tuned low-pressure screw assembly, engineered for optimal output, while the subsequent stage houses a high-pressure screw assembly. Central to this advanced process are sealing air films enveloping each screw, facilitating the compression journey through three critical phases: smooth air intake, dynamic pressurization that elevates efficiency to unprecedented heights, and an exhaust stage executed with remarkable precision.
First stage compression: The initiation of the two-stage screw air compressor's operation showcases remarkable engineering prowess. A sophisticated low-pressure screw assembly deftly directs gas into the compression chamber through a carefully calibrated suction valve. As the rotor spins at an impressive speed, the gas undergoes initial compression, laying the groundwork for intensified compression in the subsequent stage.
Second stage compression: Advancing into the second phase, the gas is channeled into a meticulously crafted, more confined screw space where both pressure and temperature are expertly increased to unprecedented levels. The process reaches its zenith as the exhaust valve opens, allowing the high-pressure gases to exit, thus completing the intricate compression cycle with unmatched efficiency.
The sophisticated air compression process begins as ambient air seamlessly flows through the air filter, meeting a touch of lubricating oil within the compression chamber. This blend undergoes an initial compression to an intermediate pressure, followed by substantial cooling through interaction with the oil mist in the cooling channel. The cooled gas then advances to the second-stage rotor, where it undergoes a secondary compression phase, achieving the desired final exhaust pressure. This expertly coordinated cycle concludes as the compressed gas is gracefully expelled through the exhaust valve, marking the completion of a comprehensive and highly efficient air compression process.
