Embark on a fascinating exploration of pioneering air compression technology at Sanzhi (Henan) Compressor Co., Ltd.! Enter a realm of unmatched energy efficiency with our Powerful Sanzhi 200KW Screw Air Compressor with Centrifugal Fan (1.3MPa). Experience a thrilling journey through the complexities of single-stage and multi-stage compression systems. In the pursuit of efficiency, single-stage systems strive to mirror their multi-stage counterparts, overcoming challenges such as transmission losses, bearing friction, and the cooling effects from liquid viscosity with groundbreaking innovations. In contrast, multi-stage compression sets a new standard with its strategic reduction of the compression ratio at each stage, significantly minimizing energy consumption compared to single-stage systems. This meticulously engineered approach not only elevates overall system performance but also drastically cuts down on excessive energy use, establishing a revolutionary benchmark in power optimization and efficiency.
Introducing the revolutionary two-stage screw air compressor by Sanzhi-a marvel in modern engineering. This cutting-edge device features an innovative dual rotary screw design, where each stage showcases an active screw that drives a passive counterpart via a sophisticated external power transfer mechanism. The first stage is equipped with a pioneering low-pressure screw assembly, refined for peak performance. Meanwhile, the second stage boasts a high-pressure screw assembly, central to its operations are sealing air films encasing each screw. These films orchestrate compression through three critical phases: seamless air intake, dynamic pressurization that propels efficiency to unprecedented levels, and a flawlessly executed exhaust phase with unmatched precision.
First Stage Compression: The initiation of the two-stage screw air compressor process represents an extraordinary engineering feat. It begins with a state-of-the-art low-pressure screw assembly that channels gas flow into the compression chamber through a finely tuned suction valve. As the rotor rotates rapidly, the gas undergoes its initial compression, laying a robust foundation for the intensified compression that follows in the succeeding stage.
Second Stage Compression: As the gas advances to the second stage, it is funneled into a uniquely designed, more compact screw chamber. Here, pressures and temperatures are meticulously amplified to impressive heights, reaching the apex of the cycle as the exhaust valve opens, allowing high-pressure gases to be expelled. This marks the culmination of the sophisticated compression cycle, executed with exceptional efficiency and precision.
The intricate journey of air compression begins as ambient air effortlessly flows through the air filter, merging seamlessly with a subtle touch of lubricating oil in the compression chamber. This blend undergoes initial compression to an intermediate pressure, followed by substantial cooling as it mingles with oil mist in the cooling channel. The cooled gas then advances to the second-stage rotor, encountering a secondary compression phase to attain the desired final exhaust pressure. This meticulously choreographed cycle concludes with the graceful expulsion of compressed gas through the exhaust valve, marking the completion of an elaborate and highly efficient air compression process.
