Working Principle
Step into the realm of advanced air compression technology with Sanzhi (Henan) Compressor Co., Ltd.! Experience the fusion of innovation and efficiency in air compression, where single-stage systems aim to mirror the excellence of multi-stage systems. Overcoming obstacles like transmission losses and cooling effects, single-stage systems strive for efficiency. However, multi-stage compression rises above by artfully minimizing the compression ratio at each step, thus establishing itself as the pinnacle of power efficiency. This sophisticated method significantly enhances performance while slashing energy consumption, setting a new benchmark in power management and operational efficacy.
Introducing the pioneering two-stage screw air compressor by Sanzhi - a marvel of contemporary engineering ingenuity. This modern device boasts a dual rotary screw mechanism, with each stage featuring an active and passive screw pair connected through an expertly designed power transfer system. The first stage incorporates a specialized low-pressure screw assembly, crafted for peak performance, while the second stage houses a high-pressure screw setup. Central to this process are sealing air films enveloping each screw, steering compression through three critical phases: seamless air intake, dynamic pressurization enhancing efficiency, and a precision-driven exhaust phase.
First Stage Compression: Embark on the fascinating journey of the two-stage screw air compressor, where the process initiates with a cutting-edge low-pressure screw assembly. This assembly draws gas into the compression chamber through a meticulously calibrated suction valve. As the rotor spins, the gas undergoes initial compression, laying the groundwork for further intensification in the subsequent stage.
Second Stage Compression: In the second stage, the gas is directed into a specially designed, compact screw chamber. Here, both pressure and temperature are expertly elevated, culminating in the cycle's peak as the exhaust valve activates, releasing high-pressure gases. This marks the completion of the sophisticated compression cycle, performed with remarkable efficiency and precision.
Embark on the sophisticated air compression journey as ambient air seamlessly filters in, blending smoothly with a hint of lubricating oil inside the compression chamber. This mixture undergoes initial compression to an intermediate pressure, subsequently cooled through interaction with oil mist within the cooling channel. The chilled gas advances to the second-stage rotor, experiencing secondary compression to achieve the final exhaust pressure. This meticulously coordinated cycle concludes with the refined expulsion of compressed gas via the exhaust valve, marking the culmination of an intricate and efficient air compression process.
