Working Principle
Step into a realm of unparalleled innovation with the Sanzhi 200KW Screw Air Compressor with Centrifugal Fan for High Pressure, where the forefront of air compression technology awaits! This is your passport to a world of energy efficiency like never before, inviting you to explore the advanced dynamics that govern both single-stage and multi-stage compression systems. While single-stage systems endeavor to reach the efficiency levels of multi-stage systems, they encounter hurdles such as transmission losses, bearing friction, and the cooling effects of liquid viscosity. These challenges demand groundbreaking solutions. Yet, it's the multi-stage compression that shines, masterfully minimizing the compression ratio at each stage. It stands as the epitome of efficiency, consuming far less power than its single-stage counterparts. This meticulously crafted approach not only elevates the system's overall performance but also drastically cuts down on energy use, setting a new standard in power optimization and efficiency.
Presenting the game-changing two-stage screw air compressor from Sanzhi (Henan) Compressor Co., Ltd. - a masterpiece of contemporary engineering excellence. This sophisticated apparatus features an innovative dual rotary screw design, where each stage incorporates an active screw that propels a passive counterpart through a precisely engineered external power transfer mechanism. The initial stage is outfitted with a state-of-the-art low-pressure screw assembly, meticulously calibrated for peak performance. The following stage boasts a high-pressure screw assembly. At the heart of this process are sealing air films that envelop each screw, orchestrating the compression through three critical phases: flawless air intake, dynamic pressurization elevating efficiency to new heights, and culminating in an exhaust phase executed with exceptional precision.
First Stage Compression: Behold the inception of the two-stage screw air compressor process, a remarkable feat of refined engineering sophistication. It begins with a pioneering low-pressure screw assembly that expertly channels gas into the compression chamber via a meticulously calibrated suction valve. As the rotor spins at high velocity, the gas undergoes its initial compression, laying a strong foundation for the intensified compression that occurs in the subsequent stage.
Second Stage Compression: As the gas advances to the second stage, it enters a uniquely engineered, more compact screw chamber. Here, pressures and temperatures are methodically elevated to extraordinary levels. At the peak of the cycle, the exhaust valve activates, allowing high-pressure gases to be released, marking the completion of this intricate compression cycle, executed with remarkable efficiency and precision.
The intricate air compression journey unfolds as ambient air flows effortlessly through the air filter, seamlessly merging with a touch of lubricating oil within the compression chamber. This mixture undergoes an initial compression to reach an intermediate pressure, followed by significant cooling through interaction with oil mist in the cooling channel. The cooled gas then proceeds to the second-stage rotor, where a secondary compression phase occurs, achieving the desired final exhaust pressure. This intricately coordinated cycle concludes as the compressed gas is elegantly expelled through the exhaust valve, marking the completion of a comprehensive and highly efficient air compression process.
