Working Principle
In the cutting-edge world of air compression, maximizing efficiency means mastering the sophisticated balance between single-stage and multi-stage systems. Ideally, the energy needs for single-stage should seamlessly match those of multi-stage systems. Yet, the reality often demands additional power due to inevitable factors like transmission power losses, bearing friction, and liquid viscosity cooling effects. By skillfully reducing the compression ratio at each stage, multi-stage systems achieve unparalleled efficiency, requiring far less power than single-stage equivalents. This not only boosts overall system proficiency but also dramatically cuts excess energy use, setting a new standard in power optimization.
Introducing the revolutionary two-stage screw air compressor, a true marvel of modern engineering. This advanced apparatus incorporates a cutting-edge dual rotary screw mechanism; each stage showcases an active screw driving a passive screw through a precisely crafted external power transfer system. The first stage features a low-pressure screw assembly, optimized for peak performance, while the second stage is designed with a high-pressure screw assembly. Essential to this process are sealing air films around each screw, guiding compression through three critical phases: smooth air intake, dynamic pressurization enhancing efficiency to unprecedented levels, and the final exhaust phase completing the cycle with unparalleled 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 center stage, directing gas into the compression chamber via a precisely crafted suction valve. As the rotor spins at remarkable speed, the gas undergoes initial compression, paving the way for intensified compression in the subsequent phase.
Second stage compression: Transitioning to the second stage, the gas enters a uniquely designed, more confined screw space, where pressures and temperatures are meticulously elevated to unparalleled heights. The process reaches its zenith at the opening of the exhaust valve, allowing high-pressure gases to exit the system, thus completing the intricate compression cycle with unrivaled efficiency.
The sophisticated air compression journey begins as ambient air smoothly traverses through the air filter, blending with a touch of lubricating oil within the compression chamber. This mixture undergoes initial compression to intermediate pressure, followed by significant cooling through interaction with oil mist in the cooling channel. The cooled gas then progresses to the second-stage rotor, where it encounters a secondary compression phase, reaching the desired final exhaust pressure. This meticulously orchestrated cycle culminates as the compressed gas is elegantly expelled through the exhaust valve, marking the conclusion of a comprehensive and efficient air compression process.
