Working Principle
Embark on an exhilarating journey into the forefront of air compression technology with Sanzhi's latest innovation! Discover unprecedented energy efficiency and elevate your exploration into an exciting adventure with the advanced dynamics of single-stage and multi-stage compression systems. While single-stage systems strive for efficiency akin to their multi-stage counterparts, they encounter challenges like transmission losses, bearing friction, and cooling effects due to liquid viscosity, necessitating breakthrough solutions. Multi-stage compression, by cleverly 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 marvel of modern engineering brilliance. This sophisticated apparatus showcases an innovative dual rotary screw design, where each stage features an active screw driving 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: Witness the initiation of the two-stage screw air compressor process, a marvel of exquisite engineering sophistication. It begins 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 intensified compression in the subsequent stage.
Second Stage Compression: As the gas advances 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, releasing high-pressure gases. 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.
