Working Principle
In the cutting-edge realm of air compression, the quest for supreme efficiency unfolds as an intricate ballet between single-stage and multi-stage compression systems. Ideally, energy demands for single-stage operations should harmoniously align with those of multi-stage systems. Yet, practical scenarios demand additional energy due to unavoidable factors such as transmission power losses, friction from bearings, and cooling effects induced by liquid viscosity. By artfully minimizing the compression ratio at each stage, multi-stage compression systems emerge as paragons of efficiency, requiring significantly less power than their single-stage counterparts. This elevates overall system performance and significantly reduces unnecessary energy consumption, setting a groundbreaking benchmark in power optimization.
Introducing the revolutionary two-stage screw air compressor, a marvel of contemporary engineering excellence. This sophisticated apparatus features a state-of-the-art 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 first stage is equipped with a low-pressure screw assembly, finely tuned for peak performance, while the second stage is engineered with a high-pressure screw assembly. Central to this process are sealing air films enveloping each screw, which guide the compression journey through three crucial phases: the seamless intake of air, dynamic pressurization that elevates efficiency to unprecedented heights, and the final exhaust phase that completes the cycle with unmatched precision.
First stage compression: The onset of the two-stage screw air compressor's operation showcases engineering prowess. An exceedingly advanced low-pressure screw assembly takes the lead, guiding gas into the compression chamber through a precisely crafted suction valve. As the rotor spins at a remarkable velocity, the gas undergoes an initial compression, setting the stage for heightened compression in the subsequent phase.
Second stage compression: As the process transitions into the second stage, gas enters a meticulously designed, more confined screw space, where pressures and temperatures are meticulously heightened to unmatched levels. The operation reaches a critical juncture with the opening of the exhaust valve, allowing high-pressure gases to exit the system, thereby consummating the sophisticated compression cycle with unparalleled efficiency.
The refined journey of air compression begins as ambient air gracefully passes through the air filter, merging with a touch of lubricating oil within the compression chamber. This blend undergoes initial compression to intermediate pressure, followed by significant cooling through interaction with oil mist in the cooling channel. The cooled gas then progresses to the second-stage rotor, where it experiences a secondary compression phase, achieving the desired final exhaust pressure. This meticulously orchestrated cycle culminates as the compressed gas is elegantly released through the exhaust valve, marking the completion of a comprehensive and efficient air compression process.
