Working Principle
At the cutting edge of air compression technology, Sanzhi (Henan) Compressor Co., Ltd. is heralding a new era of unparalleled efficiency. Our high-power systems deftly navigate the challenges presented by both single-stage and multi-stage designs. Although theoretically, the energy requirements might align, real-world factors like transmission power loss, bearing friction, and cooling viscosity introduce the need for additional energy. However, by expertly managing compression ratios at each stage, our multi-stage systems demonstrate extraordinary efficiency, consuming considerably less power than single-stage systems. This innovation not only elevates system performance to new heights but also slashes unnecessary energy expenditure, setting an unprecedented benchmark in power efficiency.
Introducing the groundbreaking two-stage screw air compressor-a marvel of contemporary engineering. This extraordinary machine features an innovative dual rotary screw configuration, where each stage consists of an active screw driving a passive screw, seamlessly powered by a sophisticated external power transfer system. The first stage features a meticulously calibrated low-pressure screw setup for optimal function, while the second stage is equipped with a high-pressure screw assembly. Central to this intricate operation are sealing air films that embrace each screw, guiding the compression through three essential stages: effortless air intake, dynamic pressurization boosting efficiency, and the final exhaust phase that concludes the cycle with breathtaking precision.
First stage compression: The initiation of the two-stage screw air compressor operation is a testament to engineering excellence. An ultra-refined low-pressure screw assembly takes charge, masterfully directing gas into the compression chamber via a precisely engineered suction valve. As the rotor reaches impressive speeds, the gas undergoes initial compression, setting the stage for the more intense compression of the next phase.
Second stage compression: As the process advances to the second stage, the gas moves into a specially designed, more compact screw chamber, where pressure and temperature are expertly elevated to new heights. The process reaches its zenith as the exhaust valve opens, permitting the release of high-pressure gases, thereby culminating the sophisticated compression cycle with unmatched efficiency.
The intricate process of air compression begins as ambient air gracefully passes through the air filter, mingling with a hint of lubricating oil within the compression chamber. This mixture undergoes an initial compression to intermediate pressure, followed by significant cooling through interaction with oil mist in the cooling channel. The cooled gas then advances to the second-stage rotor, where it encounters a secondary compression phase, achieving the desired final exhaust pressure. This expertly choreographed sequence concludes as the compressed gas is elegantly expelled through the exhaust valve, completing a comprehensive and highly efficient air compression process.
