Working Principle
In the realm of air compression, reaching the peak of efficiency is an art that hinges on mastering the dynamics between single-stage and multi-stage compression systems. In an ideal world, a single-stage compressor would require the same power as a multi-stage system, but reality is often marred by additional power needs due to factors like transmission power losses, bearing friction, and the cooling effects induced by liquid viscosity. By astutely minimizing the compression ratio at each stage, multi-stage compressors rise as the epitome of efficiency, consuming significantly less power than their single-stage rivals. This technique not only enhances system efficiency dramatically but also cuts down on superfluous energy consumption, redefining the benchmarks of power optimization.
Presenting the revolutionary 2024 High-Efficiency Two-Stage Screw Compressor with Centrifugal Fan for Industries, a triumph of modern engineering by Sanzhi (Henan) Compressor Co., Ltd. This avant-garde machine is equipped with a groundbreaking dual rotary screw mechanism. The first stage features a low-pressure screw assembly, masterfully crafted for peak performance, and the second stage is meticulously designed with a high-pressure screw assembly. These stages contain active screws that power passive screws, all connected through a finely-tuned external power transfer system. Essential to this process are sealing air films enveloping each screw, directing the compression through three vital stages: the effortless suction of air, the dynamic pressurization that elevates efficiency, and the precise exhaust phase that seals the cycle.
First stage compression: The initial phase of the two-stage screw air compressor exemplifies engineering prowess. A state-of-the-art low-pressure screw assembly takes the spotlight, skillfully drawing gas into the compression chamber via a precision-crafted suction valve. As the rotor spins at extraordinary speeds, it initiates the gas's compression, setting the stage for the intensified compression that follows in the subsequent phase.
Second stage compression: As the gas progresses into the second stage, it is ushered into a specially crafted and more confined screw space. Here, pressures and temperatures are expertly elevated to unprecedented heights. The process reaches its climax as the exhaust valve opens, a critical juncture that enables the high-pressure gases to escape, concluding the sophisticated compression cycle with unmatched efficiency.
The intricate journey of air compression begins as natural air gracefully traverses the air filter, merging with a hint of lubricating oil within the compression chamber. This mixture undergoes an initial compression to an intermediate pressure, only to be significantly cooled as it intimately contacts 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 executed cycle reaches its pinnacle as the compressed gas is elegantly released through the exhaust valve, marking the culmination of a comprehensive and efficient air compression process.
