Working Principle
At the forefront of air compression technology, Sanzhi (Henan) Compressor Co., Ltd. embarks on an innovative journey to achieve unparalleled efficiency, harmonizing the benefits of both single-stage and multi-stage systems. While theoretically, the energy demands of single-stage systems should match those of multi-stage systems, real-world challenges such as transmission power losses, bearing friction, and cooling due to viscosity demand more energy. Through meticulous optimization of compression ratios at each stage, multi-stage systems stand out as the epitome of efficiency, consuming considerably less power than single-stage units. This remarkable advancement not only boosts system performance but also significantly reduces unnecessary energy usage, establishing a new benchmark in power efficiency.
Introducing the groundbreaking two-stage screw air compressor-a marvel of contemporary engineering excellence. This extraordinary device features an innovative dual rotary screw mechanism, where each stage consists of an active screw driving a passive screw via a masterfully designed external power transfer system. The first stage harbors a finely calibrated low-pressure screw assembly for optimal performance, while the second stage features a high-pressure screw assembly. Crucial to this intricate operation are the sealing air films that envelop each screw, guiding the compression process through three essential phases: seamless air intake, dynamic pressurization that propels efficiency to unprecedented levels, and a concluding exhaust phase that flawlessly completes the cycle.
First stage compression: The inception of the two-stage screw air compressor's function is a testament to engineering marvel. A cutting-edge low-pressure screw assembly takes charge, expertly guiding gas into the compression chamber through a precisely engineered suction valve. As the rotor rotates at an impressive pace, the gas is initially compressed, setting the stage for further intensified compression in the subsequent stage.
Second stage compression: Transitioning to the second stage, gas is funneled into a meticulously designed, compact screw space, where pressure and temperature are elevated to extraordinary heights. The process culminates as the exhaust valve opens, allowing high-pressure gases to be released, thus completing the sophisticated compression cycle with unrivaled efficiency.
The intricate air compression process begins as ambient air is smoothly drawn in through the air filter, mingling with a trace of lubricating oil within the compression chamber. This mixture undergoes initial compression to intermediate pressure, followed by significant cooling via interaction with oil mist in the cooling channel. The cooled gas advances to the second-stage rotor, where it undergoes a secondary compression phase, achieving the target final exhaust pressure. This expertly coordinated cycle concludes as the compressed gas is elegantly expelled through the exhaust valve, marking the achievement of a comprehensive and highly efficient air compression process.
