Working Principle
At the forefront of innovation in air compression technology, Sanzhi (Henan) Compressor Co., Ltd. proudly stands as an industry leader, pioneering a new era of exceptional efficiency in air compression. By seamlessly integrating the advantages of both single-stage and multi-stage systems, Sanzhi adeptly tackles challenges like transmission power losses, bearing friction, and viscosity-related cooling, challenges that typically require extra energy. Through meticulous refinement of compression ratios at each stage, Sanzhi's multi-stage systems showcase unmatched efficiency, demanding significantly less power compared to their single-stage counterparts. This groundbreaking advancement not only elevates system performance but also drastically reduces energy consumption, solidifying Sanzhi's position as a trailblazer in power-efficient solutions.
Introducing the groundbreaking two-stage screw air compressor-an epitome of modern engineering brilliance. This extraordinary apparatus integrates a cutting-edge dual rotary screw mechanism, with each stage featuring an innovative active screw, propelling a passive screw via a precisely engineered external power transfer mechanism. The initial stage features a meticulously calibrated low-pressure screw assembly designed for optimal output, while the subsequent stage houses a high-pressure screw assembly. Central to this advanced process are sealing air films encircling each screw, guiding the compression journey through three crucial phases: effortless air intake, vigorous pressurization that elevates efficiency to unprecedented levels, and a final exhaust phase executed with impeccable precision.
First stage compression: The initiation of the two-stage screw air compressor's operation epitomizes engineering brilliance. An advanced low-pressure screw assembly expertly channels gas into the compression chamber through a precisely calibrated suction valve. As the rotor spins at an astonishing speed, the gas undergoes initial compression, laying the groundwork for enhanced compression in the forthcoming stage.
Second stage compression: Advancing into the second phase, gas transitions into a meticulously designed, more compact screw chamber where pressure and temperature are expertly elevated to exceptional levels. The process culminates as the exhaust valve opens, allowing the high-pressure gases to exit, thus completing the intricate compression cycle with unparalleled efficiency.
The sophisticated air compression process begins as ambient air smoothly passes through the air filter, encountering a touch of lubricating oil within the compression chamber. This blend undergoes 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 experiences a secondary compression phase, reaching the desired final exhaust pressure. This expertly orchestrated cycle concludes as the compressed gas is elegantly expelled through the exhaust valve, marking the culmination of a comprehensive and highly efficient air compression process.
