Introducing the revolutionary 250kw Energy-Efficient Water Cooling Two-Stage Screw Air Compressor by Sanzhi (Henan) Compressor Co., Ltd. This technological masterpiece showcases a refined dual rotary screw setup, where each stage presents an active screw that drives a passive counterpart via a meticulously crafted external power transfer mechanism. The initial stage, steered by a low-pressure screw assembly, is fine-tuned for optimum efficiency, succeeded by a subsequent high-pressure screw assembly. Central to this advanced mechanism are the sealing air films surrounding each screw, orchestrating compression through three critical stages: flawless intake, dynamic pressurization achieving unparalleled efficiency, and a precise exhaust phase concluding the cycle with unmatched precision.
First Stage Compression: The initial phase of the two-stage screw air compressor exemplifies extraordinary engineering prowess. A precisely calibrated low-pressure screw assembly spearheads the operation, channeling gas into the compression chamber via an expertly designed suction valve. As the rotor spins at remarkable velocities, the gas undergoes initial compression, laying the foundation for intensified compression in the subsequent phase, thus priming the system for exceptional performance and efficiency.
Second Stage Compression: Progressing to the second stage, the gas is expertly channeled into a distinctively compact screw space, where both pressure and temperature are elevated to exceptional levels. This phase reaches its peak as the exhaust valve opens, permitting high-pressure gases to exit the system, marking the culmination of an intricate and highly efficient compression cycle, characterized by remarkable sophistication.
The refined air compression journey commences as ambient air gracefully flows through the air filter, seamlessly merging with a hint of lubricating oil within the compression chamber. This blend experiences initial compression to reach intermediate pressure, followed by substantial cooling through interaction with oil mist in the cooling channel. The cooled gas then progresses to the second-stage rotor, undergoing a secondary compression phase to achieve the desired final exhaust pressure. This meticulously orchestrated cycle concludes as the compressed gas is elegantly expelled through the exhaust valve, marking the completion of an exceptionally comprehensive and efficient air compression process.
