Working Principle
In the forefront of air compression technology, the pursuit of unmatched efficiency unfolds as an intriguing comparison between single-stage and multi-stage compression systems. Ideally, energy consumption for single-stage systems should parallel that of multi-stage designs. Yet, real-world scenarios demonstrate the need for additional energy due to factors like transmission power losses, bearing friction, and liquid viscosity-induced cooling effects. By artfully reducing the compression ratio in each stage, multi-stage compression stands as the pinnacle of efficiency, demanding significantly less power than single-stage counterparts. This not only enhances overall system performance but also dramatically reduces unnecessary energy usage, creating a groundbreaking standard in power optimization.
Presenting the groundbreaking two-stage screw air compressor, a testament to modern engineering brilliance. This state-of-the-art machine features an advanced dual rotary screw mechanism; each stage highlights an active screw propelling a passive screw through a precisely designed external power transfer system. The first stage is equipped with a low-pressure screw assembly, expertly fine-tuned for optimum performance, while the second stage is crafted with a high-pressure screw assembly. Central to this process are sealing air films encasing each screw, guiding the compression through three essential phases: the smooth intake of air, dynamic pressurization that elevates efficiency to unprecedented levels, and the final exhaust phase completing the cycle with unparalleled precision.
First stage compression: The initiation of the two-stage screw air compressor's function exemplifies engineering mastery. A highly sophisticated low-pressure screw assembly takes charge, channeling gas into the compression chamber via a precisely engineered suction valve. As the rotor spins at an impressive velocity, the gas undergoes an initial stage of compression, setting the groundwork for enhanced compression in the subsequent phase.
Second stage compression: As the process evolves into the second stage, the gas enters a uniquely designed, more compact screw space, where pressures and temperatures are meticulously elevated to exceptional levels. The operation reaches a pivotal moment as the exhaust valve opens, permitting the high-pressure gases to exit the system, thereby completing the sophisticated compression cycle with unmatched efficiency.
The refined journey of air compression commences with ambient air gracefully flowing through the air filter, merging with a hint of lubricating oil in the compression chamber. This blend undergoes an initial compression to an intermediate pressure, followed by substantial cooling via 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 coordinated cycle culminates as the compressed gas is elegantly discharged through the exhaust valve, marking the conclusion of a comprehensive and efficient air compression process.
