Working Principle
At the leading edge of air compression technology, Sanzhi (Henan) Compressor Co., Ltd. sets a pioneering benchmark for ultimate efficiency in air compression. Striking a harmonious equilibrium between single-stage and multi-stage systems, Sanzhi ingeniously navigates real-world dynamics like transmission power losses, bearing friction, and viscosity-related cooling that typically require extra energy. By adeptly refining compression ratios at each stage, Sanzhi's multi-stage systems stand as paragons of efficiency, demanding substantially less power than single-stage systems. This breakthrough not only amplifies system performance but also dramatically reduces unnecessary energy usage, establishing a pioneering standard in power efficiency.
Introducing the groundbreaking two-stage screw air compressor-a marvel of contemporary engineering excellence. This extraordinary machine features a cutting-edge dual rotary screw design, with each stage comprising an agile active screw, propelling a passive screw via a masterfully designed external power transfer system. The first stage features a finely-tuned low-pressure screw assembly optimized for peak performance, while the second stage houses a high-pressure screw assembly. Central to this sophisticated process are sealing air films enveloping each screw, orchestrating the compression journey through three critical stages: effortless air intake, dynamic pressurization that escalates efficiency to unprecedented heights, and a concluding exhaust phase executed with impeccable precision.
First stage compression: The inception of the two-stage screw air compressor's operation epitomizes engineering mastery. A state-of-the-art low-pressure screw assembly takes charge, adeptly channeling gas into the compression chamber through a precisely engineered suction valve. As the rotor whirls at an impressive speed, the gas undergoes initial compression, setting the stage for intensified compression in the subsequent stage.
Second stage compression: Transitioning into the second phase, gas enters a meticulously crafted, more confined screw space where pressure and temperature are expertly elevated to unprecedented heights. The process reaches its zenith as the exhaust valve opens, allowing high-pressure gases to exit, thereby completing the intricate compression cycle with unparalleled efficiency.
The sophisticated air compression process begins as ambient air seamlessly enters through the air filter, encountering a trace of lubricating oil within the compression chamber. This mixture undergoes an initial compression to intermediate pressure, followed by substantial cooling through interaction with oil mist within the cooling channel. The cooled gas then advances to the second-stage rotor, where it experiences a secondary compression phase, achieving the desired final exhaust pressure. This expertly coordinated cycle culminates as the compressed gas is elegantly expelled through the exhaust valve, marking the completion of a comprehensive and highly efficient air compression process.
