Working Principle
At the forefront of air compression innovation, Sanzhi (Henan) Compressor Co., Ltd. has established a trailblazing standard for peak efficiency in air compression solutions. By skillfully balancing the unique advantages of single-stage and multi-stage systems, Sanzhi expertly addresses real-world factors such as transmission power losses, bearing friction, and viscosity-related cooling demands, which often require additional energy. Through the meticulous refinement of compression ratios at each stage, Sanzhi's multi-stage systems emerge as exemplars of efficiency, consuming significantly less power than their single-stage counterparts. This revolutionary advancement not only enhances system performance but also significantly curtails extraneous energy consumption, setting a new benchmark in power efficiency.
Introducing the revolutionary two-stage screw air compressor-a true marvel of modern engineering ingenuity. This remarkable piece of machinery showcases an innovative dual rotary screw design, with each stage featuring a dynamic active screw that drives a passive screw through a brilliantly designed external power transfer system. The initial stage boasts a finely-calibrated low-pressure screw assembly tailored for optimal performance, while the subsequent stage incorporates a high-pressure screw assembly. At the core of this intricate process are sealing air films encasing each screw, orchestrating the compression journey through three pivotal stages: seamless air intake, dynamic pressurization that elevates efficiency to extraordinary levels, and a concluding exhaust phase executed with flawless precision.
First stage compression: The inception of the two-stage screw air compressor's operation showcases engineering excellence. A cutting-edge low-pressure screw assembly assumes control, skillfully directing gas into the compression chamber via a precisely engineered suction valve. As the rotor spins at an impressive speed, the gas undergoes initial compression, paving the way for intensified compression in the subsequent stage.
Second stage compression: As the process transitions into the second phase, gas enters a meticulously designed, more confined screw space where pressure and temperature are expertly elevated to remarkable levels. The process reaches its pinnacle as the exhaust valve opens, enabling high-pressure gases to exit, thereby concluding the intricate compression cycle with unmatched efficiency.
The sophisticated air compression process begins as ambient air smoothly enters through the air filter, encountering a trace of lubricating oil within the compression chamber. This mixture undergoes an initial compression to intermediate pressure, followed by substantial cooling through interaction with oil mist within the cooling channel. The cooled gas then progresses to the second-stage rotor, where it experiences a secondary compression phase, achieving the desired final exhaust pressure. This expertly coordinated cycle culminates as the compressed gas is gracefully expelled through the exhaust valve, marking the completion of a comprehensive and highly efficient air compression process.
