Working Principle
At the forefront of air compression innovation, Sanzhi (Henan) Compressor Co., Ltd. proudly stands as a leader, redefining the standards of efficiency in the industry. By seamlessly integrating the advantages of both single-stage and multi-stage systems, Sanzhi adeptly overcomes common challenges such as transmission power losses, bearing friction, and viscosity-related cooling, which traditionally consume more energy. Through meticulous optimization of compression ratios at each stage, Sanzhi's multi-stage systems deliver unmatched efficiency, requiring significantly less power compared to single-stage systems. This groundbreaking innovation not only enhances system performance but also dramatically reduces energy consumption, positioning Sanzhi as a pioneer in power-efficient solutions.
Introducing the cutting-edge two-stage screw air compressor-an epitome of modern engineering brilliance. This extraordinary device features an advanced dual rotary screw mechanism. Each phase houses a dynamic active screw, propelling a passive screw via a precisely designed external power transfer system. The initial phase comprises a highly tuned low-pressure screw assembly optimized for peak output, while the subsequent phase accommodates a high-pressure screw assembly. Essential to this sophisticated process are sealing air films encasing each screw, enabling the compression journey through three critical stages: smooth air intake, vigorous pressurization that elevates efficiency to unprecedented heights, and an exhaust stage completed with unmatched precision.
First stage compression: The inception of the two-stage screw air compressor's operation embodies engineering excellence. A sophisticated low-pressure screw assembly expertly channels gas into the compression chamber through a meticulously calibrated suction valve. As the rotor spins at an impressive speed, the gas undergoes initial compression, laying the groundwork for enhanced compression in the subsequent stage.
Second stage compression: Advancing 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 culminates as the exhaust valve opens, allowing the high-pressure gases to exit, thereby completing the intricate compression cycle with unprecedented efficiency.
The sophisticated air compression process begins as ambient air smoothly flows through the air filter, mixing with a trace of lubricating oil within the compression chamber. This blend undergoes an initial compression to intermediate pressure, followed by substantial cooling through interaction with the oil mist in the cooling channel. The cooled gas then moves 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 elegantly discharged through the exhaust valve, marking the end of a comprehensive and highly efficient air compression process.
