Working Principle
In the pioneering landscape of air compression technology, the pursuit of outstanding efficiency unfolds as a fascinating synergy between single-stage and multi-stage compression systems. While theoretically, the energy requirements for single-stage operations should align perfectly with those of multi-stage systems, practical circumstances dictate otherwise. Real-world scenarios necessitate additional energy input due to unavoidable factors like transmission power losses, friction from bearings, and cooling effects linked to liquid viscosity. By expertly minimizing the compression ratio at each stage, multi-stage compression establishes itself as the pinnacle of efficiency, demanding markedly less power than single-stage systems. This not only enhances overall system performance but dramatically reduces excessive energy consumption, setting an innovative standard in power optimization.
Introducing the groundbreaking two-stage screw air compressor, an icon of modern engineering mastery. This advanced apparatus features a state-of-the-art dual rotary screw mechanism; each stage is equipped with an active screw propelling a passive screw through a carefully engineered external power transfer system. The first stage contains a low-pressure screw assembly, precisely calibrated for optimal performance, while the second stage is crafted with a high-pressure screw assembly. Integral to this process are sealing air films that encase each screw, guiding the compression sequence through three essential phases: effortless air intake, dynamic pressurization that enhances efficiency to unparalleled heights, and the final exhaust phase, completing the cycle with exceptional precision.
First stage compression: The initiation of the two-stage screw air compressor's operation is a testament to engineering excellence. A highly sophisticated low-pressure screw assembly takes the lead, channeling gas into the compression chamber through a meticulously designed suction valve. As the rotor rotates at a remarkable speed, the gas undergoes an initial compression, paving the way for intensified compression in the subsequent phase.
Second stage compression: As the process advances into the second stage, the gas is directed into a distinctively engineered, more confined screw space, where both pressure and temperature are meticulously elevated to unparalleled levels. The operation reaches a pivotal point when the exhaust valve is unveiled, allowing the high-pressure gases to exit the system, thus completing the intricate compression cycle with unmatched efficiency.
The meticulous journey of air compression begins with ambient air smoothly passing through the air filter, merging with a trace of lubricating oil inside the compression chamber. This mixture undergoes initial compression to an intermediate pressure, followed by substantial cooling through interaction with oil mist within 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 culminates as the compressed gas is gracefully expelled through the exhaust valve, marking the completion of a comprehensive and efficient air compression process.
