Working Principle
At the forefront of air compression technology, Sanzhi (Henan) Compressor Co., Ltd. pioneers a journey toward optimal efficiency, striking a harmonious balance between single-stage and multi-stage systems. In theory, energy needs of single-stage should rival that of multi-stage, but reality introduces factors such as transmission power losses, bearing friction, and viscosity-related cooling that call for additional energy. By skillfully minimizing compression ratios at each stage, multi-stage systems emerge as paragons of efficiency, requiring significantly less power than their single-stage counterparts. This advancement not only enhances system performance but also drastically curtails superfluous energy consumption, setting a groundbreaking standard in power efficiency.
Behold the revolutionary two-stage screw air compressor-a beacon of modern engineering triumph. This exceptional device showcases a cutting-edge dual rotary screw mechanism, with each stage comprising an active screw propelling a passive screw via an expertly crafted external power transfer system. The first stage boasts a fine-tuned low-pressure screw assembly for peak performance, while the second stage accommodates a high-pressure screw assembly. Essential to this intricate process are sealing air films enveloping each screw, directing the compression journey through three pivotal phases: effortless air intake, dynamic pressurization that elevates efficiency to new heights, and a final exhaust phase that completes the cycle with remarkable precision.
First stage compression: The commencement of the two-stage screw air compressor's operation epitomizes engineering brilliance. An ultra-advanced low-pressure screw assembly assumes control, skillfully channeling gas into the compression chamber through a meticulously designed suction valve. As the rotor spins at an impressive speed, the gas undergoes initial compression, laying the groundwork for intensified compression in the next stage.
Second stage compression: As the process transitions to the second stage, gas enters a specially crafted, more confined screw space, where pressure and temperature are expertly elevated to unprecedented levels. The process reaches its pinnacle 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 commences as ambient air gracefully 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 proceeds 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.
