Working Principle
In the cutting-edge realm of air compression, the pursuit of exceptional efficiency is an enthralling balance between single-stage and multi-stage compression systems. Ideally, energy demands of single-stage operations should seamlessly align with those of their multi-stage counterparts. Yet, in practical scenarios, additional energy is necessitated by factors such as transmission power losses, friction from bearings, and the cooling effect of liquid viscosity. By adeptly minimizing the compression ratio at each stage, multi-stage compression stands as the pinnacle of efficiency, utilizing considerably less power compared to single-stage systems. This not only enhances overall system performance but also significantly reduces unnecessary energy consumption, establishing a groundbreaking benchmark in power optimization.
Introducing the innovative two-stage screw air compressor, a testament to modern engineering brilliance. This sophisticated apparatus features a state-of-the-art dual rotary screw mechanism; each stage highlights an active screw driving a passive screw via a meticulously engineered external power transfer system. The first stage is equipped with a low-pressure screw assembly, expertly tuned for optimal performance, while the second stage is engineered with a high-pressure screw assembly. Central to this process are sealing air films enveloping each screw, guiding the compression journey through three vital phases: the seamless air intake, dynamic pressurization elevating efficiency to unprecedented heights, and the final exhaust phase completing the cycle with unmatched precision.
First stage compression: The commencement of the two-stage screw air compressor's operation epitomizes engineering excellence. A remarkably advanced low-pressure screw assembly takes the lead, directing gas into the compression chamber through a precisely crafted suction valve. As the rotor spins at an impressive speed, the gas undergoes an initial compression, setting the stage for intensified compression in the subsequent phase.
Second stage compression: As the process transitions to the second stage, the gas enters a uniquely designed, more confined screw space, where pressures and temperatures are meticulously enhanced to unmatched levels. The operation reaches a critical juncture upon the opening of the exhaust valve, allowing the high-pressure gases to exit the system, thereby completing the sophisticated compression cycle with unparalleled efficiency.
The refined air compression journey begins with ambient air effortlessly traversing through the air filter, merging with a hint of lubricating oil within the compression chamber. This blend undergoes initial compression to intermediate pressure, followed by substantial cooling via interaction with oil mist in the cooling channel. The cooled gas then progresses 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 elegantly expelled through the exhaust valve, marking the completion of a comprehensive and efficient air compression process.
