Working Principle
In the cutting-edge realm of air compression technology, achieving unparalleled efficiency is an exhilarating dance between single-stage and multi-stage compression systems. Theoretically, energy requirements for single-stage operations are designed to resemble those of multi-stage systems. However, practical implementation reveals that additional energy expenditure arises due to factors like transmission power losses, friction from bearings, and the cooling effects induced by liquid viscosity. By artfully minimizing the compression ratio at each stage, multi-stage compression systems exhibit superior efficiency, demanding significantly less power than single-stage counterparts. This innovative approach not only elevates overall system performance but also drastically reduces unwarranted energy consumption, establishing a pioneering benchmark in power optimization and efficiency.
Introducing the groundbreaking two-stage screw air compressor, an epitome of modern engineering brilliance. This marvel of machinery features an intricate dual rotary screw mechanism, with each stage boasting an active screw driving a passive screw through a finely-tuned external power transfer system. The first stage is equipped with a meticulously engineered low-pressure screw assembly, expertly calibrated for optimal performance, while the second stage is designed with a high-pressure screw assembly. Central to this process are sealing air films that envelop each screw, guiding the compression journey through three crucial phases: seamless air intake, dynamic pressurization that elevates efficiency to unprecedented heights, and the final exhaust phase that completes the cycle with unparalleled precision and finesse.
First stage compression: The operation of the two-stage screw air compressor is initiated with engineering precision. An advanced low-pressure screw assembly takes the lead, skillfully channeling gas into the compression chamber through a precisely crafted suction valve. As the rotor spins with impressive velocity, the gas undergoes its initial compression phase, paving the way for intensified compression in the subsequent second stage, ensuring maximum efficiency and performance.
Second stage compression: As the process advances to the second stage, the gas enters a uniquely designed, more confined screw space, where pressures and temperatures are meticulously elevated to extraordinarily high levels. The operation reaches a pivotal moment as the exhaust valve opens, allowing the high-pressure gases to exit the system, thus completing the sophisticated compression cycle with unmatched efficiency and precision.
The refined journey of air compression commences with ambient air gracefully flowing through the meticulously designed air filter, merging seamlessly with a touch of lubricating oil within the compression chamber. This harmonious blend undergoes initial compression to intermediate pressure, followed by significant cooling through interaction with oil mist in the cooling channel. The cooled gas then progresses to the second-stage rotor, where it experiences a secondary compression phase, achieving the desired final exhaust pressure. This meticulously orchestrated cycle culminates as the compressed gas is elegantly released through the exhaust valve, marking the completion of a comprehensive, efficient, and sophisticated air compression process.
