Working Principle
In the cutting-edge realm of air compression technology, Sanzhi (Henan) Compressor Co., Ltd. stands at the forefront of innovation, optimizing efficiency between single-stage and multi-stage compression systems. Despite theoretical energy parity, real-world applications call for additional energy to counteract inevitable factors such as transmission power losses, bearing friction, and cooling effects due to liquid viscosity. By skillfully minimizing the compression ratio at each phase, multi-stage compression emerges as the zenith of energy efficiency, requiring significantly less power than its single-stage counterpart. This not only boosts overall system performance but also dramatically slashes unnecessary energy consumption, establishing a groundbreaking benchmark in power efficiency.
Introducing the revolutionary two-stage screw air compressor from Sanzhi (Henan) Compressor Co., Ltd., an epitome of modern engineering prowess. This remarkable machine boasts an advanced dual rotary screw mechanism; each stage is intricately designed with an active screw that propels a passive screw through a meticulously engineered external power transfer system. The first stage features a low-pressure screw assembly, optimized for peak performance, while the second stage encompasses a high-pressure screw assembly. At the core of this operation are sealing air films surrounding each screw, orchestrating the compression process through three pivotal phases: seamless air intake, dynamic pressurization that elevates efficiency to unparalleled levels, and the final exhaust phase that completes the cycle with extraordinary precision.
First stage compression: The commencement of the two-stage screw air compressor's operation is a testament to engineering excellence. An ultra-advanced low-pressure screw assembly takes command, directing gas into the compression chamber via a meticulously engineered suction valve. As the rotor rotates at an impressive pace, the gas undergoes an initial compression, laying the foundation for enhanced compression in the succeeding stage.
Second stage compression: As the operation proceeds to the second stage, the gas transitions into a specially crafted, more confined screw space where pressures and temperatures are meticulously elevated to unprecedented levels. This process reaches its zenith as the exhaust valve opens, allowing high-pressure gases to escape, thereby concluding the sophisticated compression cycle with unmatched efficiency.
The elegant process of air compression commences with ambient air gently traversing through the air filter, encountering a hint of lubricating oil within the compression chamber. This blend 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, achieving the desired final exhaust pressure. This meticulously orchestrated cycle culminates as the compressed gas is gracefully released through the exhaust valve, marking the completion of a comprehensive and efficient air compression process.
