Working Principle
In the forefront of air compression innovation, the pursuit of supreme efficiency skillfully intertwines the dynamics of single-stage and multi-stage compression systems. Although theoretically, the energy needs of single-stage systems should match those of their multi-stage counterparts, real-world applications demand additional energy due to unavoidable factors such as transmission power losses, bearing friction, and the cooling effects induced by liquid viscosity. By skillfully minimizing the compression ratio at each phase, multi-stage compression emerges as the epitome of efficiency, requiring significantly less power than single-stage systems. This not only augments the system's performance but also considerably curtails energy consumption, setting an unprecedented benchmark in power efficiency.
Introducing the revolutionary two-stage screw air compressor, an epitome of cutting-edge engineering brilliance. This advanced apparatus boasts an innovative dual rotary screw mechanism; each stage is equipped with an active screw propelling a passive screw through a meticulously designed external power transfer system. The first stage incorporates a low-pressure screw assembly, expertly calibrated for optimal performance, while the second stage features a high-pressure screw assembly. At the heart of this process are sealing air films around each screw, orchestrating the compression journey through three vital phases: smooth air intake, dynamic pressurization elevating efficiency to unprecedented heights, and the final exhaust phase completing the cycle with exceptional accuracy.
First stage compression: Commencing the operation of the two-stage screw air compressor signifies the pinnacle of engineering prowess. An exceptionally sophisticated low-pressure screw assembly takes the helm, directing gas into the compression chamber via a precisely engineered suction valve. As the rotor rotates at an impressive velocity, the gas undergoes initial compression, laying the foundation for intensified compression in the subsequent stage.
Second stage compression: As the process advances to the second stage, the gas transitions into a specially crafted, more compact screw space, where pressures and temperatures are meticulously elevated to new heights. The cycle reaches a pivotal juncture as the exhaust valve opens, allowing high-pressure gases to exit, thereby completing the advanced compression cycle with unparalleled efficiency.
The refined air compression process commences with ambient air effortlessly flowing through the air filter, encountering a trace of lubricating oil within the compression chamber. This fusion undergoes an initial compression to intermediate pressure, succeeded by substantial cooling as it interacts with oil mist in the cooling channel. The cooled gas advances to the second-stage rotor, experiencing a secondary compression phase that achieves the desired final exhaust pressure. This meticulously orchestrated cycle culminates as the compressed gas is elegantly discharged through the exhaust valve, marking the conclusion of an exhaustive and efficient air compression process.
