Internal Structure Frontside: The front view of the internal structure reveals the meticulously designed components that harmonize to provide superior air compression. Every element is strategically positioned to optimize functionality and efficiency.
Internal Structure Backside: At the rear, the internal structure showcases a seamless blend of precision engineering and cutting-edge technology, all working in unison to deliver consistent, high-quality performance in every operation.
Working Principle: The ingenuity behind this air compressor lies in its sophisticated working principle, designed to maximize efficiency while minimizing energy consumption, setting a benchmark in modern air compression technology.
In the ideal realm of air compression, the energy required for a single-stage operation would perfectly mirror the cumulative energy of multiple stages. However, practical factors like coupling transmission intricacies, bearing friction, and the cooling influence of fluid viscosity increase energy requirements. To boost efficiency, it is critical to reduce the compression ratio at each stage. This strategy ensures that the total power demand for multi-stage compression remains lower than that of a single-stage process, making it a more energy-efficient solution.
The two-stage screw air compressor exemplifies the pinnacle of contemporary engineering excellence, incorporating a dual rotary screw design featuring active and passive screws. The active screw, powered by an external energy source, actuates the passive screw. Beginning with a low-pressure screw assembly in the initial stage, the operation progresses to a high-pressure configuration in the subsequent stage. Each screw is encased in an air film that seals it, facilitating the compression of gas through a flawless sequence of suction, pressurization, and discharge as the screws revolve.
First Stage Compression: In this crucial introductory phase of gas compression, air is drawn into the screw's compression chamber via the suction valve. Here, the rapid rotation of the rotor compresses the gas with remarkable efficiency, directing it seamlessly to the second compression stage.
Second Stage Compression: This advanced stage involves gas entering a more confined screw chamber, where it is subjected to heightened compression at elevated temperatures and pressures. The exhaust valve then skillfully opens, allowing the precise release of high-pressure gas from the system, demonstrating superior engineering expertise.
The process initiates with ambient air being drawn into the initial stage through an air filter, where it converges with a precise amount of lubricating oil in the compression chamber. This mixture undergoes compression to a medium pressure and is subsequently cooled within a channel, mingling with oil mist to effectively lower its temperature. The cooled gas is then directed to the second-stage rotor for further compression, achieving the ultimate exhaust pressure. This cycle concludes with the elegant egress of high-pressure gas through the exhaust valve, exemplifying a perfectly orchestrated air compression system.
