Working Principle
In the innovative arena of air compression, the pursuit of ultimate efficiency is an intriguing comparison between single-stage and multi-stage systems. Ideally, energy requirements for single-stage operations should align perfectly with multi-stage systems. However, real-world scenarios necessitate additional energy due to inherent factors like transmission power losses, bearing friction, and cooling effects from liquid viscosity. By artfully minimizing the compression ratio at each stage, multi-stage compression stands as a paragon of efficiency, demanding considerably less power than single-stage models. This enhances overall system performance and significantly reduces excess energy consumption, establishing a pioneering benchmark in power optimization.
Presenting the groundbreaking two-stage screw air compressor, a marvel of modern engineering brilliance. This advanced machine features a state-of-the-art dual rotary screw mechanism; each stage operates with an active screw driving a passive screw through a precisely engineered external power transfer system. The first stage is equipped with a low-pressure screw assembly, meticulously calibrated for peak efficiency, while the second stage is engineered with a high-pressure screw assembly. Central to this process are sealing air films encasing each screw, guiding the compression journey through three crucial phases: seamless air intake, dynamic pressurization enhancing efficiency to new heights, and the final exhaust phase completing the cycle with unparalleled precision.
First stage compression: Commencing the two-stage screw air compressor's operation illustrates engineering excellence. An exceptionally advanced low-pressure screw assembly takes charge, channeling gas into the compression chamber through a precisely designed suction valve. As the rotor spins at remarkable speed, the gas undergoes initial compression, paving the way for enhanced compression in the following phase.
Second stage compression: As the process advances to the second stage, the gas enters a distinctively designed, more confined screw space, where pressures and temperatures are meticulously elevated to exceptional levels. The operation reaches a pivotal moment with the opening of the exhaust valve, enabling the high-pressure gases to exit the system, thus completing the sophisticated compression cycle with extraordinary efficiency.
The refined journey of air compression begins with ambient air gently passing through the air filter, merging with lubricating oil within the compression chamber. This mixture undergoes initial compression to 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 undergoes a secondary compression phase, achieving the desired final exhaust pressure. This meticulously orchestrated cycle concludes as the compressed gas is smoothly released through the exhaust valve, marking the completion of a comprehensive and efficient air compression process.
