Working Principle
In the realm of air compression, unleashing the highest potential for efficiency is achieved through expertly mastering the dynamics between single-stage and multi-stage compression systems. Ideally, the energy requirements for a single-stage operation would align perfectly with those of multiple stages. However, in practice, additional power is often necessary due to unavoidable factors like transmission power loss, friction from bearings, and the cooling effects caused by liquid viscosity. By minimizing the compression ratio at each stage with expert precision, multi-stage compression emerges as the pinnacle of efficiency, necessitating significantly less power compared to its single-stage counterpart. This technique not only elevates overall system efficiency but also dramatically curtails excess energy consumption, establishing a groundbreaking benchmark in power optimization.
Introducing the revolutionary two-stage screw air compressor, a masterpiece of cutting-edge engineering. This sophisticated device features an advanced dual rotary screw mechanism, with each stage showcasing an active screw that drives a passive screw through a meticulously crafted external power transfer system. The initial stage is outfitted with a low-pressure screw assembly, expertly calibrated for peak performance, while the second stage is precisely constructed with a high-pressure screw assembly. Central to this process are sealing air films enveloping each screw, guiding the compression journey through three critical phases: the seamless intake of air, the dynamic pressurization that elevates efficiency to new heights, and the concluding exhaust phase that completes the cycle with unmatched precision.
First stage compression: The onset of the two-stage screw air compressor's operation is a testament to engineering excellence. An advanced low-pressure screw assembly takes center stage, guiding gas into the compression chamber through a meticulously designed suction valve. As the rotor spins at incredible velocity, the gas undergoes initial compression, laying the foundation for the enhanced compression that awaits in the subsequent phase.
Second stage compression: As the gas transitions to the second stage, it enters a uniquely engineered, more confined screw space, where pressures and temperatures are meticulously increased to unprecedented levels. The process culminates at the opening of the exhaust valve, a pivotal moment that allows the high-pressure gases to exit the system, thereby completing the sophisticated compression cycle with unrivaled efficiency.
The sophisticated journey of air compression begins with ambient air effortlessly passing through the air filter and mingling with a trace of lubricating oil within the compression chamber. This mixture undergoes an initial compression to intermediate pressure, followed by substantial cooling through close interaction with oil mist in the cooling channel. The cooled gas then advances to the second-stage rotor, where it experiences a secondary compression phase, achieving the desired final exhaust pressure. This meticulously orchestrated cycle reaches its zenith as the compressed gas is gracefully discharged through the exhaust valve, marking the culmination of a comprehensive and efficient air compression process.
