Working Principle
In the avant-garde world of air compression technology, achieving peak efficiency is a fascinating interplay between single-stage and multi-stage systems. Theoretically, the energy requirements for single-stage compressors should ideally align with those for multi-stage setups. Yet, in practice, additional energy becomes necessary due to unavoidable factors such as transmission power losses, bearing friction, and cooling effects from liquid viscosity. By minimizing the compression ratio at each stage with precision, multi-stage compression becomes the pinnacle of efficiency, consuming remarkably less power compared to single-stage alternatives. This not only significantly enhances system performance but also dramatically reduces unnecessary energy consumption, establishing a new standard in power optimization.
Introducing the groundbreaking two-stage screw air compressor, an epitome of modern engineering brilliance. This innovative machine features a state-of-the-art dual rotary screw mechanism, where each stage has an active screw that drives a passive screw through a precisely engineered external power transfer system. The first stage is equipped with a low-pressure screw assembly, optimized for exceptional performance, while the second stage is designed with a high-pressure screw assembly. Central to this process are sealing air films enveloping each screw, guiding the compression process through three essential stages: the seamless intake of air, dynamic pressurization elevating efficiency to unprecedented levels, and the final exhaust phase completing the cycle with unparalleled precision.
First Stage Compression: The commencement of the two-stage screw air compressor's operation showcases remarkable engineering expertise. An advanced low-pressure screw assembly takes the lead, channeling gas into the compression chamber through a meticulously designed suction valve. As the rotor spins at impressive speeds, the gas undergoes an initial compression, setting the stage for intensified compression in the subsequent phase.
Second Stage Compression: As the process advances into the second stage, the gas enters a uniquely designed, more confined screw space, where pressures and temperatures are carefully elevated to unmatched levels. This operation reaches a pivotal moment with the opening of the exhaust valve, permitting the release of high-pressure gases from the system, thereby completing the sophisticated compression cycle with unparalleled efficiency.
The elegant journey of air compression begins 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 an intermediate pressure, followed by substantial cooling through 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, reaching the desired final exhaust pressure. This carefully orchestrated cycle concludes as the compressed gas is gracefully discharged through the exhaust valve, marking the successful completion of an efficient air compression process.
