Working Principle
At the forefront of innovation in air compression technology, Sanzhi (Henan) Compressor Co., Ltd. has established itself as a leader, setting a new standard for exceptional efficiency in air compression. By harmoniously merging the benefits of single-stage and multi-stage systems, Sanzhi skillfully addresses challenges such as transmission power losses, bearing friction, and viscosity-related cooling, which usually demand additional energy. Through precise refinement of compression ratios at each stage, Sanzhi's multi-stage systems exemplify unparalleled efficiency, necessitating significantly less power than their single-stage counterparts. This revolutionary advancement not only enhances system performance but also significantly curtails energy consumption, positioning Sanzhi as a trailblazer in power-efficient solutions.
Presenting the revolutionary two-stage screw air compressor-a masterpiece of modern engineering ingenuity. This remarkable apparatus incorporates a state-of-the-art dual rotary screw mechanism, with each stage encompassing a dynamic active screw, driving a passive screw through a meticulously engineered external power transfer system. The initial stage boasts a finely calibrated low-pressure screw assembly optimized for maximum output, whereas the subsequent stage accommodates a high-pressure screw assembly. Integral to this advanced process are sealing air films surrounding each screw, facilitating the compression journey through three pivotal phases: seamless air intake, vigorous pressurization that elevates efficiency to new heights, and a concluding exhaust stage executed with exquisite precision.
First stage compression: The commencement of the two-stage screw air compressor's function showcases engineering excellence. An advanced low-pressure screw assembly skillfully directs gas into the compression chamber via a precisely calibrated suction valve. As the rotor rotates at a remarkable velocity, the gas is initially compressed, setting the foundation for enhanced compression in the subsequent stage.
Second stage compression: Progressing into the second phase, gas enters a carefully designed, more confined screw space where pressure and temperature are expertly amplified to unprecedented levels. The process reaches its peak as the exhaust valve opens, permitting the high-pressure gases to exit, thereby completing the intricate compression cycle with unmatched efficiency.
The advanced air compression process commences as ambient air effortlessly flows through the air filter, encountering 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 the oil mist in the cooling channel. The cooled gas then proceeds to the second-stage rotor, where it undergoes a secondary compression phase, achieving the targeted final exhaust pressure. This expertly coordinated cycle concludes as the compressed gas is gracefully expelled through the exhaust valve, marking the completion of a comprehensive and highly efficient air compression process.
