Working Principle
In the innovative sphere of air compression, the pursuit of ultimate efficiency unfolds as a fascinating interplay between single-stage and multi-stage compression systems. While theoretically, the energy requirements for single-stage operations might equate to their multi-stage counterparts, in reality, additional energy is imperative due to inherent factors such as transmission power losses, bearing friction, and the cooling effects driven by liquid viscosity. Through expertly reducing the compression ratio at each stage, multi-stage compression stands as the pinnacle of efficiency, demanding notably less power than single-stage systems. This not only enhances the system's overall performance but also drastically cuts down on superfluous energy use, establishing a revolutionary standard in power optimization.
Introducing the groundbreaking two-stage screw air compressor, an epitome of modern engineering excellence. This sophisticated device features a pioneering dual rotary screw mechanism; each stage showcases an active screw driving a passive screw through a precisely engineered external power transfer system. The initial stage is equipped with a low-pressure screw assembly, perfectly calibrated for optimal performance, while the second stage is constructed with a high-pressure screw assembly. Central to this operation are sealing air films encircling each screw, guiding the compression process through three crucial phases: the seamless intake of air, dynamic pressurization that elevates efficiency to new heights, and the final exhaust phase, completing the cycle with unmatched accuracy.
First stage compression: Initiating the operation of the two-stage screw air compressor is a testament to engineering mastery. An advanced low-pressure screw assembly takes charge, channeling gas into the compression chamber via an intricately designed suction valve. As the rotor rotates at a remarkable speed, the gas undergoes its initial compression, setting the stage for intensified compression in the next phase.
Second stage compression: Transitioning into the second stage, the gas enters a meticulously crafted, more confined screw space, where pressures and temperatures are precisely elevated to unparalleled levels. The operation reaches a pivotal moment at the opening of the exhaust valve, permitting the high-pressure gases to exit the system, thus completing the sophisticated compression cycle with exceptional efficiency.
The elegant journey of air compression commences with ambient air smoothly passing through the air filter, merging with a hint of lubricating oil within the compression chamber. This mixture undergoes initial compression to intermediate pressure, followed by significant cooling through interaction with an oil mist in the cooling channel. The cooled gas then progresses to the second-stage rotor, where it undergoes a secondary compression phase, reaching the desired final exhaust pressure. This meticulously coordinated cycle concludes as the compressed gas is gracefully discharged through the exhaust valve, marking the completion of a comprehensive and efficient air compression process.
