Working Principle
Leading the charge in air compression innovation, Sanzhi (Henan) Compressor Co., Ltd. masterfully harmonizes efficiency with cutting-edge multi-stage compression systems. While in theory, energy use of single-stage and multi-stage systems should match, real-world variables like transmission losses, bearing friction, and cooling from liquid viscosity demand more energy. Multi-stage compression, by optimizing the compression ratio at each stage, achieves superior efficiency, requiring significantly less power than single-stage systems. This not only boosts system performance but also slashes unnecessary energy consumption, pioneering a new benchmark in power efficiency.
Unveiling the revolutionary two-stage screw air compressor by Sanzhi, an engineering marvel designed with precision and innovation. This advanced machine integrates a modern dual rotary screw mechanism; each stage features an active screw driving a passive screw via a carefully engineered power transfer system. The first stage incorporates a low-pressure screw assembly, optimized for superior performance, while the second stage contains a high-pressure screw assembly. Crucial to this process are the sealing air films encasing each screw, directing the compression through three critical phases: smooth air intake, dynamic pressurization enhancing efficiency, and a precise exhaust phase completing the cycle with outstanding accuracy.
First stage compression: The two-stage screw air compressor operation begins with a showcase of engineering brilliance. An advanced low-pressure screw assembly directs gas into the compression chamber through a meticulously designed suction valve. As the rotor spins at impressive speeds, the gas is initially compressed, laying the foundation for further enhancement in the following stage.
Second stage compression: As the operation advances into the second stage, the gas is funneled into a custom-designed, more restrictive screw space, where pressure and temperature reach new peaks. The process hits a pivotal moment as the exhaust valve opens, releasing high-pressure gases, thereby completing the sophisticated compression cycle with unmatched efficiency.
The refined air compression process begins as ambient air effortlessly moves through the air filter, encountering a hint of lubricating oil within the compression chamber. This fusion undergoes initial compression to intermediate pressure, followed by thorough cooling via oil mist interactions in the cooling channel. The cooled gas then proceeds to the second-stage rotor for a secondary compression phase, reaching the intended final exhaust pressure. This meticulously crafted cycle concludes as the compressed gas is gracefully expelled through the exhaust valve, concluding an elegantly efficient air compression process.
