However, multi-stage compression excels by minimizing compression ratios at each stage, significantly enhancing efficiency and reducing power consumption. This meticulously crafted approach not only boosts performance but also drastically cuts energy usage, setting an unprecedented standard in power efficiency.
Introducing the revolutionary two-stage screw air compressor by Sanzhi (Henan) Compressor Co., Ltd. This engineering marvel features a dual rotary screw design, with each stage powered by an ingenious external power transfer mechanism. The initial stage utilizes a state-of-the-art low-pressure screw assembly, optimized for peak performance, which is followed by a high-pressure screw assembly. Sealing air films around each screw guide the compression through three pivotal phases: seamless air intake, dynamic pressurization achieving unmatched efficiency, and a precisely executed exhaust phase.
First Stage Compression: Witness the inception of the compression journey with the pioneering two-stage screw air compressor. This marvel begins with a low-pressure screw assembly channeling gas into the compression chamber through an expertly engineered suction valve. As the rotor energetically spins, the gas experiences its initial compression, laying a robust foundation for the intensified compression that occurs in the subsequent stage.
Second Stage Compression: As the gas moves to the second stage, it enters a uniquely designed, compact screw chamber. Here, pressures and temperatures are elevated to remarkable levels, reaching the cycle's apex as the exhaust valve opens, allowing the high-pressure gases to be released. This marks the culmination of the intricate compression cycle, executed with outstanding precision and efficiency.
The intricate journey of air compression begins as ambient air effortlessly passes through the air filter, seamlessly blending with a hint of lubricant within the compression chamber. This mixture undergoes initial compression to an intermediate pressure, followed by significant cooling via oil mist interactions in the cooling channel. The cooled gas then proceeds to the second-stage rotor for secondary compression, achieving the desired final exhaust pressure. This carefully orchestrated cycle concludes with the graceful expulsion of the compressed gas through the exhaust valve, marking the end of a highly efficient and comprehensive air compression process.
