Working Principle
At the forefront of air compression technology, Sanzhi (Henan) Compressor Co., Ltd. leads a pioneering journey towards unparalleled efficiency, deftly balancing the advantages of single-stage and multi-stage systems. While theoretically, the energy requirements of single-stage systems should match those of multi-stage systems, real-world factors such as transmission power losses, bearing friction, and viscosity-related cooling demand extra energy. By masterfully minimizing compression ratios at each stage, multi-stage systems stand as models of efficiency, demanding considerably less power than single-stage systems. This remarkable advancement not only boosts system performance but also significantly reduces unnecessary energy usage, setting a revolutionary new benchmark in power efficiency.
Behold the revolutionary two-stage screw air compressor, a shining example of modern engineering prowess. This outstanding device features a state-of-the-art dual rotary screw mechanism, with each stage comprising an active screw that propels a passive screw through an expertly designed external power transfer system. The first stage features a finely-tuned low-pressure screw assembly for optimal performance, while the second stage hosts a high-pressure screw assembly. Crucial to this sophisticated process are the sealing air films enveloping each screw, guiding the compression journey through three essential phases: seamless air intake, dynamic pressurization that elevates efficiency to extraordinary levels, and a final exhaust phase that completes the cycle with remarkable precision.
First stage compression: The initiation of the two-stage screw air compressor's operation embodies engineering excellence. An ultra-advanced low-pressure screw assembly takes command, expertly channeling gas into the compression chamber through a meticulously crafted suction valve. As the rotor spins at an impressive velocity, the gas undergoes initial compression, establishing the foundation for enhanced compression in the subsequent stage.
Second stage compression: As the process advances to the second stage, the gas enters a specially designed, more confined screw space, where pressure and temperature are expertly elevated to unprecedented heights. The procedure reaches its zenith as the exhaust valve opens, allowing high-pressure gases to exit, thereby completing the sophisticated compression cycle with unmatched efficiency.
The sophisticated process of air compression begins as ambient air gently enters through the air filter, encountering a trace of lubricating oil within the compression chamber. This blend undergoes an initial compression to 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, where it experiences a secondary compression phase, achieving the intended final exhaust pressure. This expertly orchestrated 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.
