Working Principle
In the avant-garde arena of air compression technology, reaching optimal efficiency is an exquisite equilibrium between single-stage and the innovative multi-stage compression systems. On a theoretical level, the energy demands for single-stage processes should align with those of multi-stage systems. Yet, practical application reveals a need for additional energy due to variables like transmission power losses, bearing friction, and cooling effects from liquid viscosity. By skillfully minimizing the compression ratio at each stage, multi-stage compression emerges as a paragon of efficiency, requiring significantly less power than single-stage alternatives. This cutting-edge innovation transforms overall system performance, markedly diminishing superfluous energy usage, and establishes a pioneering benchmark in power optimization.
Presenting the groundbreaking two-stage screw air compressor, a pinnacle of contemporary engineering prowess. This sophisticated machine boasts an intricate dual rotary screw system, with each stage featuring an active screw that propels a passive screw through a precisely designed external power transfer mechanism. The first stage incorporates a low-pressure screw assembly, meticulously optimized for peak performance, while the second stage boasts a high-pressure screw assembly. Central to this process are the sealing air films that envelop each screw, orchestrating the compression journey through three essential stages: seamless air intake, dynamic pressurization that elevates efficiency to new zeniths, and the concluding exhaust phase that completes the cycle with extraordinary precision.
First stage compression: The operation of the two-stage screw air compressor commences with meticulous engineering precision. A cutting-edge low-pressure screw assembly initiates the process, channeling gas into the compression chamber through an exquisitely designed suction valve. As the rotor spins with remarkable speed, the gas undergoes initial compression, laying the groundwork for intensified compression in the subsequent phase.
Second stage compression: Upon transitioning to the second stage, the gas enters a specially engineered, more compact screw space, where pressures and temperatures are meticulously elevated to exceptional heights. The operation reaches a pivotal moment as the expertly designed exhaust valve opens, allowing the high-pressure gases to exit the system, thereby completing the sophisticated compression cycle with unmatched efficiency.
The refined odyssey of air compression commences with ambient air effortlessly passing through the air filter, merging with a precise amount of lubricating oil within the compression chamber. This harmonious blend undergoes initial compression to intermediate pressure, succeeded 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 meticulously choreographed cycle culminates as the compressed gas is gracefully expelled through the exhaust valve, marking the conclusion of a comprehensive and highly efficient air compression process.
