Working Principle
In the innovative realm of air compression technology, the pursuit of peak efficiency is a fascinating interplay between single-stage and multi-stage compression systems. In theory, the energy requirements for single-stage operations should ideally match those of multi-stage counterparts. However, practical scenarios often necessitate additional energy input due to unavoidable factors such as transmission power losses, friction from bearings, and the cooling effects brought about by liquid viscosity. By adeptly minimizing the compression ratio at each stage, multi-stage compression stands as the pinnacle of efficiency, demanding significantly less power than single-stage systems. This not only enhances the overall system performance but also significantly reduces superfluous energy consumption, establishing a pioneering standard in power optimization.
Introducing the groundbreaking two-stage screw air compressor, a triumph of modern engineering. This advanced machine features a state-of-the-art dual rotary screw mechanism, where each stage comprises an active screw driving a passive screw through a precisely engineered external power transfer system. The first stage is equipped with a low-pressure screw assembly, expertly optimized for maximum output, while the second stage is designed with a high-pressure screw assembly. Crucial to this process are sealing air films that envelop each screw, guiding the compression process through three essential phases: the seamless intake of air, dynamic pressurization that boosts efficiency to new heights, and the final exhaust phase, completing the cycle with exceptional accuracy.
First stage compression: The inception of the two-stage screw air compressor's operation is a testament to engineering mastery. An extraordinarily developed low-pressure screw assembly takes charge, channeling gas into the compression chamber through a precisely designed suction valve. As the rotor rotates at an impressive speed, the gas undergoes initial compression, laying the groundwork for enhanced compression in the ensuing stage.
Second stage compression: As the process progresses to the second stage, the gas enters a specially designed, more compact screw chamber, where pressures and temperatures are meticulously heightened to unparalleled levels. The operation reaches a pivotal moment with the revelation of the exhaust valve, permitting the high-pressure gases to exit the system, thereby completing the intricate compression cycle with unmatched efficiency.
The sophisticated air compression journey begins as ambient air smoothly passes through the air filter, blending with a hint of lubricating oil within the compression chamber. This mixture undergoes an initial compression to an intermediate pressure, followed by extensive cooling through its interaction with oil mist in the cooling channel. The cooled gas then advances to the second-stage rotor, where it undergoes a secondary compression phase, reaching the desired final exhaust pressure. This meticulously planned cycle culminates as the compressed gas is elegantly expelled through the exhaust valve, marking the completion of a comprehensive and highly efficient air compression process.
