Venture into the cutting-edge realm of air compression with Sanzhi's groundbreaking innovation! Discover unmatched energy efficiency as you delve into the sophisticated workings of both single-stage and multi-stage compression systems. Single-stage systems strive for efficiency, overcoming hurdles like transmission losses, bearing friction, and cooling effects due to liquid viscosity. In contrast, multi-stage compression excels by efficiently managing compression ratios at each stage, significantly decreasing power consumption and maximizing efficiency when compared to single-stage systems. This meticulously crafted design not only boosts overall performance but also dramatically slashes energy use, setting a new benchmark in power optimization and efficiency.
Presenting the pioneering two-stage screw air compressor from Sanzhi (Henan) Compressor Co., Ltd. - a testament to modern engineering excellence. This cutting-edge device features a dual rotary screw design, where each stage incorporates an active screw driving a passive one via an expertly crafted external power transfer system. The initial stage boasts a state-of-the-art low-pressure screw assembly, fine-tuned for maximum performance, followed by a high-pressure screw assembly in the next stage. Central to this operation are sealing air films encircling each screw, conducting compression through three vital phases: flawless air intake, dynamic pressurization achieving unmatched efficiency, and a meticulously executed exhaust phase.
First Stage Compression: Witness the beginning of the two-stage screw air compressor's remarkable process - a pinnacle of engineering finesse. It starts with an avant-garde low-pressure screw assembly guiding gas into the compression chamber through a precisely calibrated suction valve. As the rotor spins with vigor, the gas undergoes its initial compression, laying a robust groundwork for intensified compression in the succeeding stage.
Second Stage Compression: Upon entering the second stage, the gas flows into a uniquely designed, more compact screw chamber. Here, pressures and temperatures are systematically elevated to extraordinary levels, reaching the cycle's climax as the exhaust valve activates, allowing the expulsion of high-pressure gases. This marks the completion of the intricate, highly efficient compression cycle, executed with precision.
The advanced air compression journey commences as ambient air effortlessly streams through the air filter, seamlessly blending with a slight trace of lubricating oil in the compression chamber. This mixture is initially compressed to an intermediate pressure, followed by considerable cooling as it interacts with oil mist in the cooling channel. The cooled gas then moves to the second-stage rotor, undergoing a secondary compression phase to reach the desired final exhaust pressure. This intricately coordinated cycle concludes as the compressed gas is elegantly expelled through the exhaust valve, marking the end of a comprehensive and exceptionally efficient air compression process.
