Working Principle
At the cutting edge of air compression innovation, Sanzhi (Henan) Compressor Co., Ltd. leads a monumental journey in achieving optimal efficiency, expertly balancing the advantages of both single-stage and multi-stage systems. In theoretical terms, the energy demands of a single-stage system should match those of a multi-stage system. However, real-world challenges such as transmission power losses, bearing friction, and viscosity-related cooling impose additional energy requirements. By adeptly minimizing compression ratios at each stage, multi-stage systems become icons of efficiency, consuming significantly less power than their single-stage counterparts. This advancement not only elevates system performance but also drastically reduces unnecessary energy consumption, establishing a groundbreaking standard in power efficiency.
Presenting the groundbreaking two-stage screw air compressor-a marvel of contemporary engineering achievements. This extraordinary apparatus features an innovative dual rotary screw mechanism. Each stage contains an active screw driving a passive screw through an expertly engineered external power transfer system. The first stage includes a finely calibrated low-pressure screw assembly for optimal performance, while the second stage houses a high-pressure screw assembly. Fundamental to this intricate process are the sealing air films encasing each screw, channeling the compression process through three critical phases: effortless air intake, dynamic pressurization that lifts efficiency to new heights, and a concluding exhaust phase, executing the cycle with remarkable precision.
First stage compression: The initiation of the two-stage screw air compressor's operation embodies engineering excellence. An ultra-advanced low-pressure screw assembly takes command, expertly directing gas into the compression chamber through a meticulously designed suction valve. As the rotor spins at an impressive speed, the gas undergoes initial compression, laying a robust foundation for intensified compression in the forthcoming stage.
Second stage compression: Transitioning seamlessly to the second stage, the gas is introduced into a specially designed, more confined screw space. Here, pressure and temperature are masterfully elevated to unprecedented levels. The process culminates as the exhaust valve opens, allowing high-pressure gases to exit, thereby completing the sophisticated compression cycle with unmatched efficiency.
The intricate process of air compression begins as ambient air gracefully enters through the air filter, encountering a trace of lubricating oil within the compression chamber. This blend undergoes an initial compression to intermediate pressure, subsequently experiencing substantial cooling through interaction with oil mist in the cooling channel. The cooled gas then advances to the second-stage rotor, where it undergoes a secondary compression phase, achieving the intended final exhaust pressure. This expertly choreographed cycle culminates as the compressed gas is elegantly expelled through the exhaust valve, marking the completion of a comprehensive and highly efficient air compression process.
