Working Principle
In the realm of air compression innovation, the quest for unparalleled efficiency is a sophisticated dance of precision between single-stage and multi-stage compression systems. Ideally, the energy requisites for single-stage operations should harmonize perfectly with those of multi-stage systems. However, real-world dynamics often necessitate additional power to counteract factors such as transmission power losses, bearing friction, and the cooling impacts of liquid viscosity. By skillfully minimizing the compression ratio at each stage, multi-stage compression emerges as the epitome of efficiency, demanding noticeably less power than single-stage alternatives. This not only amplifies overall system proficiency but also significantly curtails surplus energy consumption, establishing an extraordinary standard in power optimization.
Introducing the revolutionary two-stage screw air compressor, a marvel of contemporary engineering excellence. This cutting-edge apparatus boasts a sophisticated dual rotary screw mechanism. Each stage showcases an active screw energizing a passive screw via a meticulously crafted external power transfer system. The initial stage is endowed with a low-pressure screw assembly, meticulously calibrated for peak performance, while the subsequent stage is designed with a high-pressure screw assembly. Central to this operation are sealing air films enveloping each screw, navigating the compression process through three critical stages: the seamless intake of air, dynamic pressurization that elevates efficiency to unprecedented heights, and the final exhaust phase, completing the cycle with utmost precision and reliability.
First stage compression: The initiation of the two-stage screw air compressor's operation is a testament to engineering prowess. A highly advanced low-pressure screw assembly takes charge, directing gas into the compression chamber through a precisely articulated suction valve. As the rotor whirls at impressive velocities, the gas undergoes initial compression, paving the way for enhanced compression in the succeeding phase.
Second stage compression: As the process advances to the second stage, the gas is ushered into a uniquely crafted, more confined screw space, where pressures and temperatures are meticulously elevated to exceptional levels. The process reaches a crucial juncture upon the opening of the exhaust valve, allowing the high-pressure gases to gracefully exit the system, thus concluding the sophisticated compression cycle with unrivaled efficiency.
The intricate journey of air compression begins with ambient air smoothly traversing through the air filter, mingling with a trace of lubricating oil within the compression chamber. This mixture endures an initial compression to intermediate pressure, followed by significant cooling through interaction with oil mist in the cooling channel. The cooled gas then proceeds to the second-stage rotor, where it undergoes a secondary compression phase, achieving the desired final exhaust pressure. This meticulously orchestrated cycle culminates as the compressed gas is elegantly discharged through the exhaust valve, marking the completion of a comprehensive and efficient air compression process.
