Working Principle
In the innovative arena of air compression, maximizing efficiency is akin to a symphony of precision and technology, orchestrating the dynamic interplay between single-stage and multi-stage compression systems. Ideally, the energy needs for single-stage operations should harmonize effortlessly with those of multi-stage systems. However, the reality often demands additional power due to unavoidable factors such as transmission power losses, friction from bearings, and cooling effects brought about by liquid viscosity. By artfully reducing the compression ratio at each stage, multi-stage compression emerges as the epitome of efficiency, consuming significantly less power than its single-stage counterparts. This not only elevates overall system proficiency but profoundly curtails excess energy use, setting a revolutionary standard in power optimization.
Introducing the revolutionary two-stage screw air compressor, a marvel of modern engineering. This advanced apparatus boasts a cutting-edge dual rotary screw system; each stage is graced by an active screw driving a passive screw through a meticulously engineered external power transfer mechanism. The first stage is fitted with a low-pressure screw assembly, finely tuned for exemplary performance, while the second stage features a high-pressure screw assembly. Paramount to this process are sealing air films encasing each screw, navigating the compression journey through three pivotal phases: the seamless intake of air, dynamic pressurization elevating efficiency to unprecedented heights, and the final exhaust phase concluding the cycle with unmatched precision.
First stage compression: The initiation of the two-stage screw air compressor's operation is a testament to engineering superiority. A sophisticated low-pressure screw assembly takes precedence, channeling gas into the compression chamber through a precisely engineered suction valve. As the rotor spins at an impressive velocity, the gas undergoes initial compression, laying the groundwork for heightened compression in the subsequent phase.
Second stage compression: As the process transitions to the second stage, the gas is ushered into a uniquely engineered, more confined screw space where pressures and temperatures are meticulously elevated to unprecedented levels. The cycle reaches its zenith as the exhaust valve opens, allowing high-pressure gases to exit the system, thereby completing the intricate compression cycle with unparalleled efficiency.
The sophisticated journey of air compression begins with ambient air gracefully traversing the air filter, intertwining with a hint of lubricating oil within the compression chamber. This mixture undergoes initial compression to intermediate pressure, followed by substantial cooling through its 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 orchestrated cycle culminates as the compressed gas is elegantly expelled through the exhaust valve, marking the completion of a comprehensive and efficient air compression process.
