Working Principle
In the realm of air compression, achieving unparalleled efficiency is achieved by mastering the intricate balance of power dynamics inherent in single-stage versus multi-stage compression systems. Ideally, the energy requirements of single-stage operations would align seamlessly with those of multi-stage systems. However, in reality, additional power becomes necessary due to factors like transmission power loss, friction from bearings, and cooling effects from liquid viscosity. By cleverly minimizing the compression ratio at each stage, multi-stage compression emerges as the epitome of efficiency, demanding less power compared to single-stage counterparts. This technique not only elevates overall system performance but also dramatically curtails energy waste, setting a new standard in power optimization.
Introducing the groundbreaking two-stage screw air compressor, a marvel of modern engineering excellence. This sophisticated machine features an advanced dual rotary screw mechanism, with each stage powered by an active screw that drives a passive screw through a finely-tuned external power transfer system. The initial stage boasts a low-pressure screw assembly, optimized for peak performance, while the second stage is intricately designed with a high-pressure screw assembly. Central to this operation is a sealing air film that encases each screw, guiding the compression process through three pivotal phases: seamless air intake, dynamic pressurization elevating efficiency to unprecedented levels, and a concluding exhaust phase executed with unparalleled precision.
First stage compression: The operation of the two-stage screw air compressor begins with an engineering masterpiece. The advanced low-pressure screw assembly takes center stage, channeling gas into the compression chamber with precision through a meticulously crafted suction valve. As the rotor spins at remarkable speeds, the gas undergoes initial compression, laying the foundation for the enhanced compression awaiting in the following stage.
Second stage compression: As gas transitions to the second stage, it enters a uniquely engineered, more confined screw space where pressures and temperatures are meticulously elevated to unprecedented levels. The process peaks with the opening of the exhaust valve-a pivotal moment allowing high-pressure gases to exit the system, completing the sophisticated compression cycle with unmatched efficiency.
The sophisticated air compression journey begins as ambient air seamlessly passes through the air filter, mingling with a hint of lubricating oil within the compression chamber. This mixture undergoes initial compression to intermediate pressure, followed by substantial cooling through a close interaction with oil mist in the cooling channel. The cooled gas then advances to the second-stage rotor, experiencing a secondary compression phase to achieve the desired final exhaust pressure. This meticulously orchestrated cycle culminates as the compressed gas is gracefully discharged through the exhaust valve, marking the completion of a comprehensive and efficient air compression process.
