Working Principle
Embark on an extraordinary journey through cutting-edge air compression technologies! Step into a realm of unparalleled energy efficiency with systems designed for both single-stage and multi-stage compression. Single-stage systems, while striving for efficiency, must skillfully overcome challenges such as transmission losses, bearing friction, and the cooling effects caused by liquid viscosity, all of which demand innovative solutions. On the other hand, multi-stage compression systems showcase their prowess by strategically lowering the compression ratio at each stage. This approach not only optimizes system performance but also significantly decreases energy consumption compared to single-stage systems, setting a new revolutionary standard in power optimization and efficiency.
Introducing the revolutionary two-stage screw air compressor, a masterpiece of contemporary engineering brilliance. This avant-garde device features a cutting-edge dual rotary screw design, where each stage boasts an active screw driving a passive counterpart through a finely engineered external power transfer mechanism. The first stage is armed with a pioneering low-pressure screw assembly, meticulously engineered for optimal performance, while the second stage houses a high-pressure screw assembly. At the core of its operation lies sealing air films enveloping each screw, orchestrating the compression process through three pivotal phases: seamless air intake, dynamic pressurization that elevates efficiency to unparalleled heights, and culminating in an impeccably executed exhaust phase with unrivaled precision.
First Stage Compression: The initiation of the two-stage screw air compressor process represents an extraordinary achievement in engineering. It begins with a sophisticated low-pressure screw assembly, which skillfully directs gas flow into the compression chamber through a meticulously calibrated suction valve. As the rotor rapidly turns, the gas undergoes its primary compression, establishing a robust foundation for the intensified compression to follow in the next stage.
Second Stage Compression: As the gas advances to the second stage, it is channeled into a uniquely designed, more compact screw chamber. Here, pressures and temperatures are meticulously elevated to remarkable levels, reaching the cycle's peak as the exhaust valve is engaged, allowing high-pressure gases to be expelled. This marks the culmination of the sophisticated compression cycle, executed with exceptional precision and efficiency.
The intricate journey of air compression begins as ambient air flows effortlessly through the air filter, seamlessly merging with a hint of lubricating oil in the compression chamber. This mixture undergoes an initial compression to an intermediate pressure, followed by substantial cooling as it interacts with oil mist in the cooling channel. The cooled gas then advances to the second-stage rotor, where it encounters a secondary compression phase to achieve the desired final exhaust pressure. This meticulously orchestrated 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.
