This advanced method not only boosts system performance but also greatly reduces energy waste, establishing a revolutionary benchmark in power efficiency.
Discover the groundbreaking 250kw Energy-Efficient Water Cooling Two-Stage Screw Air Compressor by Sanzhi (Henan) Compressor Co., Ltd. This technological masterpiece features an advanced dual rotary screw mechanism, with each stage boasting an active screw that drives a passive one through a meticulously designed external power transfer system. The initial phase includes a low-pressure screw assembly optimized for peak performance, while the following stage contains a high-pressure screw assembly. Central to this intricate process are sealing air films encapsulating each screw, guiding compression through three vital phases: seamless air intake, dynamic pressurization elevating efficiency to unprecedented levels, and the final exhaust phase, completing the cycle with unmatched precision and excellence.
First Stage Compression: The first phase of the two-stage screw air compressor exemplifies engineering excellence. An intricate low-pressure screw assembly initiates the process by directing gas into the compression chamber through a precisely calculated suction valve. As the rotor rapidly spins, the gas undergoes initial compression, laying the groundwork for enhanced compression in the subsequent phase, thus gearing the system for exceptional performance.
Second Stage Compression: As the gas enters the second stage, it transitions into a meticulously engineered, more confined screw space where both pressure and temperature are precisely elevated to new peaks. This process culminates when the exhaust valve opens, allowing high-pressure gases to seamlessly exit the system, completing an intricate compression cycle defined by unmatched efficiency and sophistication.
The sophisticated air compression process begins as ambient air fluidly passes through the air filter, merging with a hint of lubricating oil within the compression chamber. This mixture experiences initial compression to intermediate pressure, followed by extensive cooling via interaction with oil mist in the cooling channel. The cooled gas then proceeds to the second-stage rotor, facing a secondary compression phase to attain the desired final exhaust pressure. This meticulously orchestrated cycle concludes as the compressed gas is elegantly discharged through the exhaust valve, marking the completion of an exceptionally thorough and efficient air compression process.
