Working Principle
In the realm of innovative air compression solutions, achieving peak efficiency hinges on the delicate balance between the dynamics of single-stage and multi-stage systems. In an ideal scenario, the energy demands of single-stage operations would perfectly align with those of multi-stage systems. Yet, real-world conditions often necessitate extra energy due to unavoidable factors like transmission power losses, friction from bearings, and cooling effects driven by liquid viscosity. By skillfully minimizing the compression ratio at each stage, multi-stage compression emerges as the ultimate efficiency leader, demanding significantly less energy than its single-stage counterparts. This advancement not only boosts overall system performance but also drastically cuts down on excess energy consumption, setting a new, unprecedented standard in power optimization.
Introducing the revolutionary two-stage screw air compressor, a marvel of modern engineering. This sophisticated appliance boasts a cutting-edge dual rotary screw mechanism; in each stage, an active screw propels a passive screw through a precisely designed external power transfer system. The first stage showcases a low-pressure screw assembly, engineered for peak performance, while the second stage features a high-pressure screw assembly. Central to this process are sealing air films enveloping each screw, orchestrating the compression journey across three critical phases: the seamless intake of air, dynamic pressurization that elevates efficiency to unprecedented levels, and the final exhaust phase, completing the cycle with unmatched precision.
First stage compression: The onset of the two-stage screw air compressor's operation exemplifies a pinnacle of engineering prowess. A highly advanced low-pressure screw assembly spearheads the process, channeling gas into the compression chamber via a precision-designed suction valve. As the rotor spins with remarkable velocity, the gas undergoes initial compression, laying the groundwork for intensified compression in the subsequent phase.
Second stage compression: Upon advancing to the second stage, the gas enters a distinctively engineered, more confined screw space, where pressures and temperatures reach meticulously heightened levels. The process culminates at the opening of the exhaust valve, where the high-pressure gases are allowed to exit the system, thereby completing the sophisticated compression cycle with unparalleled efficiency.
The intricate journey of air compression begins as ambient air gently passes through the air filter, merging with a trace of lubricating oil within the compression chamber. This blend undergoes initial compression to reach intermediate pressure, followed by significant cooling through interaction with oil mist in the cooling channel. The cooled gas then moves to the second-stage rotor, where it undergoes a secondary compression phase, achieving the desired final exhaust pressure. This meticulously orchestrated cycle concludes as the compressed gas is elegantly released through the exhaust valve, marking the completion of a comprehensive and efficient air compression process.
