This advanced approach not only boosts system performance but also dramatically reduces energy excess, establishing a revolutionary benchmark in power efficiency.
Presenting the innovative 250KW Energy-Efficient Water Cooling Two-Stage Screw Air Compressor by Sanzhi (Henan) Compressor Co., Ltd. This technological marvel showcases a sophisticated dual rotary screw mechanism, with each stage driving a passive screw through a precisely engineered external power transfer system. The initial stage features a low-pressure screw assembly, optimized for enhanced performance, while the subsequent stage houses a high-pressure screw assembly. Central to this elaborate process are sealing air films enveloping each screw, guiding compression through three pivotal phases: seamless air intake, dynamic pressurization driving efficiency to unprecedented levels, and the final exhaust phase, completing the cycle with unmatched precision and excellence.
First Stage Compression: The initial phase of the two-stage screw air compressor exemplifies engineering expertise. An intricate low-pressure screw assembly initiates the process, directing gas into the compression chamber through a meticulously calibrated suction valve. As the rotor accelerates at impressive speeds, the gas undergoes initial compression, laying the groundwork for intensified compression in the following phase, priming the system for outstanding performance.
Second Stage Compression: As gas transitions to the second stage, it enters a meticulously engineered, more confined screw space where pressure and temperature are precisely elevated to new levels. This process culminates when the exhaust valve opens, allowing high-pressure gases to exit the system seamlessly. This completes an intricate compression cycle, characterized by unparalleled efficiency and sophistication.
The sophisticated air compression process begins as ambient air effortlessly traverses the air filter, combining with a touch of lubricating oil within the compression chamber. This fusion undergoes initial compression to intermediate pressure, followed by substantial cooling through interaction with oil mist in the cooling channel. The cooled gas then proceeds to the second-stage rotor, entering 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 culmination of an exceptionally comprehensive and efficient air compression journey.
