Working Principle
Embark on an exciting journey into the forefront of air compression technology with Sanzhi's latest groundbreaking innovation! This is your gateway to unmatched energy efficiency, transforming your exploration into an exhilarating adventure with the sophisticated dynamics of both single-stage and multi-stage compression systems. While single-stage systems aim for efficiency like their multi-stage counterparts, they face challenges such as transmission losses, bearing friction, and the cooling effects of liquid viscosity that require innovative solutions. Multi-stage compression, by cleverly minimizing the compression ratio at each stage, stands as the apex of efficiency, using significantly less power than single-stage systems. This expertly crafted approach not only boosts the system's overall performance but also dramatically cuts down on energy usage, setting a groundbreaking standard in power optimization and efficiency.
Introducing the revolutionary two-stage screw air compressor from Sanzhi (Henan) Compressor Co., Ltd. - a true marvel of modern engineering excellence. This sophisticated apparatus boasts an innovative dual rotary screw design where each stage contains an active screw that drives a passive counterpart via a meticulously engineered external power transfer mechanism. The initial stage is equipped with a cutting-edge low-pressure screw assembly, finely tuned for optimal performance, while the following stage features a high-pressure screw assembly. At the core of this process are sealing air films encircling each screw, orchestrating compression through three essential stages: seamless air intake, dynamic pressurization that elevates efficiency to unprecedented heights, and concluding with an exhaust phase executed with exceptional precision.
First Stage Compression: Experience the commencement of the two-stage screw air compressor process, a marvel of exquisite engineering sophistication. It starts with a pioneering low-pressure screw assembly that expertly channels gas into the compression chamber through a meticulously calibrated suction valve. As the rotor spins rapidly, the gas undergoes its initial compression, establishing a robust foundation for the intensified compression that ensues in the subsequent stage.
Second Stage Compression: As the gas transitions into the second stage, it enters a uniquely engineered, more compact screw chamber. Here, pressures and temperatures are systematically elevated to exceptional levels, reaching the cycle's peak as the exhaust valve activates, allowing high-pressure gases to be released. This marks the completion of the intricate compression cycle, executed with extraordinary efficiency and precision.
The sophisticated air compression journey unfolds as ambient air glides effortlessly through the air filter, smoothly mixing with a trace of lubricating oil within the compression chamber. This blend undergoes initial compression to an intermediate pressure, followed by significant cooling through interaction with oil mist in the cooling channel. The cooled gas then proceeds to the second-stage rotor, where it undergoes a secondary compression phase to achieve the desired final exhaust pressure. This intricately coordinated cycle concludes as the compressed gas is elegantly expelled through the exhaust valve, signifying the culmination of a comprehensive and highly efficient air compression process.
