Working Principle
Embark on an exhilarating journey into the forefront of air compression technology with Sanzhi's latest innovation! This is your gateway to unprecedented energy efficiency, transforming your exploration into an exciting adventure through the advanced dynamics of single-stage and multi-stage compression systems. While single-stage systems strive to achieve efficiency comparable to their multi-stage counterparts, they face challenges such as transmission losses, bearing friction, and cooling effects from liquid viscosity, which require breakthrough solutions. Multi-stage compression, by ingeniously minimizing the compression ratio at each stage, stands as the pinnacle of efficiency, consuming significantly less power compared to single-stage systems. This expertly crafted methodology not only amplifies the system's overall performance but also substantially reduces energy consumption, establishing a revolutionary benchmark in power optimization and efficiency.
Introducing the revolutionary two-stage screw air compressor from Sanzhi (Henan) Compressor Co., Ltd. - a true marvel of modern engineering brilliance. This sophisticated apparatus showcases an innovative dual rotary screw design, where each stage incorporates an active screw that drives a passive counterpart through a meticulously engineered external power transfer mechanism. The initial stage is equipped with a cutting-edge low-pressure screw assembly, finely tuned for optimal performance, while the subsequent stage features a high-pressure screw assembly. Central to this process are sealing air films encircling each screw, orchestrating the compression through three vital phases: flawless air intake, dynamic pressurization elevating efficiency to unprecedented heights, and culminating in an exhaust phase executed with exceptional precision.
First Stage Compression: Experience the beginning of the two-stage screw air compressor process, a marvel of exquisite engineering sophistication. It commences with a pioneering low-pressure screw assembly that channels gas into the compression chamber through a meticulously calibrated suction valve. As the rotor spins rapidly, the gas undergoes its initial compression, establishing a robust foundation for the intensified compression that follows in the succeeding stage.
Second Stage Compression: As the gas progresses into the second stage, it enters a uniquely engineered, more compact screw chamber. Here, pressures and temperatures are systematically elevated to exceptional levels, culminating at the cycle's peak as the exhaust valve activates, allowing high-pressure gases to be released. This marks the completion of the intricate compression cycle, executed with extraordinary efficiency and precision.
The sophisticated air compression journey unfolds as ambient air glides effortlessly through the air filter, seamlessly blending with a trace of lubricating oil within the compression chamber. This mixture undergoes initial compression to an 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 undergoes a secondary compression phase to achieve the desired final exhaust pressure. This intricately coordinated cycle concludes as the compressed gas is elegantly expelled through the exhaust valve, signifying the completion of a comprehensive and highly efficient air compression process.
