Working Principle
In the illustrious domain of air compression, mastering peak efficiency requires a profound understanding of the intricate power dynamics between the systems of single-stage and multi-stage compression. In an idealized environment, the power requisites for a single stage would align seamlessly with those of multiple stages combined. However, our real-world applications frequently introduce the necessity for increased power consumption, attributable to inevitable losses such as transmission power inefficiencies, bearing friction, and the cooling effects prompted by the viscosity of fluids. By artfully minimizing the compression ratio at each individual stage, multi-stage compression distinguishes itself as a paramount player in efficiency enhancement, demanding substantially less power than its single-stage alternative. This superior methodology not only magnifies the system's overall efficiency but also dramatically reduces superfluous energy usage, thus establishing a groundbreaking benchmark in power optimization.
Introducing the state-of-the-art two-stage screw air compressor, a true marvel of modern engineering ingenuity. This advanced machine boasts an innovative dual rotary screw mechanism, with each distinct stage featuring an active screw that powers a passive screw through a meticulously designed external power transfer system. The initial stage is equipped with a low-pressure screw assembly, strategically crafted for optimal performance, while the second stage is precisely engineered with a high-pressure screw assembly. A vital component of this process is the sealing air films that envelop each screw, skillfully guiding the compression journey through three pivotal phases: the flawless suction of air, dynamic pressurization that significantly boosts the system's efficiency, and the final exhaust phase that concludes the sequence with exquisite precision.
First stage compression: The introductory phase of the two-stage screw air compressor is a testament to engineering prowess. A sophisticated low-pressure screw assembly takes the spotlight, expertly drawing gas into the compression chamber through a precision-engineered suction valve. As the rotor spins at impressive velocities, the gas undergoes initial compression, a critical step that sets the foundation for the intensified compression anticipated in the subsequent phase.
Second stage compression: As the gas progresses to the second stage, it enters a distinctively designed, more confined screw space where both pressures and temperatures are meticulously elevated to unprecedented levels. The process reaches its pinnacle with the strategic opening of the exhaust valve, a decisive moment that allows the high-pressure gases to exit the system, thereby completing the advanced compression cycle with remarkable efficiency.
The intricate and sophisticated journey of air compression commences with natural air effortlessly passing through the air filter, where it gracefully mingles with a subtle trace of lubricating oil within the compression chamber. This harmonious blend undergoes an initial compression to an intermediate pressure, followed by significant cooling through intimate interaction with oil mist in the cooling channel. The cooled gas subsequently advances to the second-stage rotor, where it encounters a secondary phase of compression, achieving the desired final exhaust pressure. This meticulously orchestrated cycle reaches its zenith as the compressed gas is elegantly released through the exhaust valve, marking the culmination of a comprehensive and highly efficient air compression process.
