Revolutionary Working Principle: Pioneering a transformative era in air compression technology, this principle is set to redefine industry standards and elevate performance benchmarks to new heights.
At the cutting edge of air compression innovation, supreme efficiency is achieved through the delicate balance between single-stage and multi-stage systems. Ideal conditions suggest equal energy consumption across both, yet realistic scenarios often demand additional power to counteract transmission losses, bearing friction, and cooling impacts. By meticulously optimizing the compression ratio at each stage, multi-stage systems deliver phenomenal efficiency, drastically curbing power consumption when compared to single-stage models. This refined methodology not only enhances system performance holistically but also significantly slashes excess energy demand, establishing a revolutionary standard in power optimization.
Introducing the revolutionary 250kw Energy-Efficient Water Cooling Two-Stage Screw Air Compressor from Sanzhi (Henan) Compressor Co., Ltd. This technological marvel is built with an advanced dual rotary screw design, where each stage features an active screw propelling a passive screw via a meticulously engineered external power transfer system. The initial phase is spearheaded by a low-pressure screw assembly, optimized for maximum output, while the subsequent stage encompasses a high-pressure screw assembly. Critical to this innovative process is the presence of sealing air films around each screw, guiding the compression through three essential phases: seamless air intake, dynamic pressurization that enhances efficiency to unparalleled levels, and the final exhaust phase, completing the cycle with precision and mastery.
First Stage Compression: The commencement phase of the two-stage screw air compressor epitomizes engineering brilliance. A sophisticated low-pressure screw assembly leads the charge, channeling gas into the compression chamber via a precisely crafted suction valve. As the rotor spins at incredible velocities, the gas undergoes initial compression, paving the way for intensified compression in the next phase, thereby priming the system for extraordinary performance.
Second Stage Compression: As the gas transitions into the second stage, it enters a uniquely designed, more confined screw space where both pressure and temperature are meticulously elevated to unprecedented heights. This process reaches its pinnacle as the exhaust valve opens, allowing high-pressure gases to exit the system, completing an intricate compression cycle characterized by unmatched efficiency and sophistication.
The sophisticated air compression journey begins as ambient air effortlessly passes through the air filter, merging with a touch of lubricating oil within the compression chamber. This mixture experiences initial compression to intermediate pressure, followed by substantial cooling via interaction with oil mist in the cooling channel. The cooled gas then advances to the second-stage rotor, undergoing a secondary compression phase to reach the desired final exhaust pressure. This meticulously orchestrated cycle culminates as the compressed gas is elegantly expelled through the exhaust valve, marking the conclusion of an exceptionally comprehensive and efficient air compression process.
