Working Principle
At the forefront of air compression innovation, Sanzhi (Henan) Compressor Co., Ltd. proudly stands as a beacon of leadership in redefining industry standards for efficiency. By skillfully merging the virtues of single-stage and multi-stage systems, Sanzhi adeptly surpasses challenges such as transmission power losses, bearing friction, and cooling issues related to viscosity, which traditionally lead to higher energy consumption. Through meticulous optimization of compression ratios in each stage, Sanzhi's multi-stage systems deliver unparalleled efficiency, demanding significantly less power compared to single-stage systems. This revolutionary innovation not only boosts system performance but also slashes energy consumption, firmly positioning Sanzhi as a trailblazer in power-efficient solutions.
Presenting the state-of-the-art two-stage screw air compressor-an embodiment of modern engineering excellence. This remarkable device boasts an advanced dual rotary screw mechanism. Each stage incorporates a dynamic active screw, driving a passive screw through a precisely engineered external power transfer system. The initial stage features a finely tuned low-pressure screw assembly, optimized for maximum output, while the subsequent stage houses a high-pressure screw assembly. Crucial to this sophisticated process are sealing air films surrounding each screw, facilitating the compression journey through three crucial stages: seamless air intake, robust pressurization elevating efficiency to unprecedented heights, and an exhaust stage completed with unmatched precision.
First stage compression: The commencement of the two-stage screw air compressor's operation epitomizes engineering excellence. A sophisticated low-pressure screw assembly expertly channels gas into the compression chamber via a meticulously calibrated suction valve. As the rotor spins at an impressive speed, the gas undergoes initial compression, setting the stage for enhanced compression in the subsequent phase.
Second stage compression: Progressing to the second phase, gas transitions into a meticulously designed, more confined screw space, where both pressure and temperature are expertly elevated to exceptional levels. The process reaches its peak as the exhaust valve opens, allowing the high-pressure gases to exit, thus completing the intricate compression cycle with unparalleled efficiency.
The sophisticated air compression process initiates as ambient air smoothly traverses through the air filter, blending with a trace of lubricating oil within the compression chamber. This mixture undergoes an initial compression to intermediate pressure, followed by substantial cooling as it interacts with the oil mist in the cooling channel. The cooled gas then advances to the second-stage rotor, where it experiences a secondary compression phase, reaching the desired final exhaust pressure. This expertly orchestrated cycle concludes as the compressed gas is elegantly discharged through the exhaust valve, marking the end of a comprehensive and highly efficient air compression process.
