Working Principle
Sanzhi (Henan) Compressor Co., Ltd. proudly stands at the forefront of air compression innovation, setting a pioneering benchmark in efficiency. Seamlessly blending the best of single-stage and multi-stage systems, Sanzhi tackles the challenges of real-world dynamics, such as transmission power losses, bearing friction, and viscosity-related cooling, which conventionally demand more energy. By artfully refining the compression ratios at each stage, Sanzhi's multi-stage systems exemplify superior efficiency, requiring significantly less power than single-stage systems. This advancement not only enhances system performance but also dramatically minimizes unnecessary energy consumption, establishing a revolutionary standard in power efficiency.
Introducing the revolutionary two-stage screw air compressor, a testament to modern engineering brilliance. This exceptional machine boasts a sophisticated dual rotary screw design, with each stage featuring an agile active screw that propels a passive screw through a meticulously crafted external power transfer system. The first stage includes a low-pressure screw assembly fine-tuned for peak performance, while the second stage contains a high-pressure screw assembly. At the heart of this advanced process are sealing air films surrounding each screw, navigating the compression journey through three critical stages: seamless air intake, dynamic pressurization that elevates efficiency to new heights, and a culminating exhaust phase executed with precision.
First stage compression: The commencement of the two-stage screw air compressor's operation exemplifies engineering precision. A cutting-edge low-pressure screw assembly takes the lead, efficiently channeling gas into the compression chamber via a precisely designed suction valve. As the rotor spins at impressive speeds, the gas undergoes initial compression, setting the stage for intensified compression in the next phase.
Second stage compression: As we transition into the second phase, the gas enters a meticulously designed, more confined screw space where pressure and temperature are expertly elevated to new heights. The process reaches its pinnacle when the exhaust valve opens, allowing high-pressure gases to exit, thus completing the intricate compression cycle with unmatched efficiency.
The intricate air compression process begins with ambient air entering effortlessly through the air filter, encountering a touch of lubricating oil in the compression chamber. This mixture experiences initial compression to an intermediate pressure, followed by significant cooling through interaction with oil mist within the cooling channel. The cooled gas then proceeds to the second-stage rotor, where it undergoes a secondary compression phase, achieving the desired final exhaust pressure. This expertly orchestrated cycle concludes as the compressed gas is gracefully expelled through the exhaust valve, marking the culmination of a comprehensive and highly efficient air compression process.
