Working Principle
Embark on an exhilarating exploration into the cutting-edge world of air compression with Sanzhi's revolutionary innovation! This is your portal to unmatched energy efficiency, transforming discovery into a thrilling voyage with the advanced dynamics of single-stage and multi-stage compression systems. While single-stage systems aim for efficiency similar to multi-stage counterparts, they face challenges like transmission losses, bearing friction, and cooling effects from liquid viscosity, necessitating revolutionary solutions. Multi-stage compression, by skillfully reducing the compression ratio at each stage, stands as the epitome of efficiency, consuming considerably less power compared to single-stage systems. This expertly designed methodology not only boosts overall performance but also significantly cuts energy use, setting a groundbreaking standard in power optimization and efficiency.
Introducing the pioneering two-stage screw air compressor from Sanzhi (Henan) Compressor Co., Ltd. - a true wonder of modern engineering mastery. This advanced apparatus features an innovative dual rotary screw design, where each stage includes an active screw that drives a passive partner through a precisely engineered external power transfer mechanism. The first stage boasts a state-of-the-art low-pressure screw assembly, finely tuned for optimal performance, while the next stage features a high-pressure screw assembly. Central to this process are sealing air films around each screw, orchestrating the compression through three critical phases: seamless air intake, dynamic pressurization elevating efficiency to unparalleled heights, and culminating in an exhaust phase executed with exceptional precision.
First Stage Compression: Observe the beginning of the two-stage screw air compressor process, a marvel of exquisite engineering sophistication. It starts with a pioneering low-pressure screw assembly that directs gas into the compression chamber through a meticulously calibrated suction valve. As the rotor spins rapidly, the gas undergoes its initial compression, laying a strong foundation for the intensified compression that follows in the succeeding stage.
Second Stage Compression: As the gas transitions 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.
