Working Principle
In the intricate world of air compression, achieving exceptional efficiency in a single-stage compression system requires that the utilized energy equal the sum of energies in a multi-stage compression system. Yet, practical challenges like energy losses at couplings, bearing friction, and cooling fluid viscosity often escalate energy demands. Multi-stage compression elegantly mitigates these issues by decreasing the compression ratio at each level, which leads to a markedly reduced total power requirement in comparison to single-stage systems.
Introducing our revolutionary two-stage screw air compressor, an engineering masterpiece featuring a dual-stage rotary screw design. This innovative system harbors a sophisticated mechanism where each stage hosts a primary and secondary screw. The primary screw dynamically powers the secondary, enhanced by an external power source. The first stage boasts a low-pressure screw assembly, succeeded by a high-pressure screw assembly in the subsequent stage. Each screw is meticulously enwrapped in a protective air cushion, proficiently executing gas compression through three essential phases: suction, pressurization, and exhaust.
First Stage Compression: The process initiates with the low-pressure screw assembly adeptly compressing the gas. As gas is drawn into the compression chamber via a suction valve, it undergoes precise compression before seamlessly transitioning to the second stage, driven by the unceasing rotation of the screw rotor.
Second Stage Compression: In this pivotal stage, the gas enters a meticulously sealed screw chamber, experiencing compression under heightened temperatures and pressures. As the stage concludes, high-pressure gases are expelled from the system upon the opening of the exhaust valve, thus completing the compression cycle.
The journey begins with ambient air being meticulously filtered before entering the initial compression stage, where it merges with a minimal amount of lubricating oil. This blend is compressed to an interstage pressure and directed through a cooling conduit, encountering a substantial oil mist that significantly diminishes its temperature. The cooled gas then proceeds to the second stage for further compression, finally being expelled through the exhaust valve, thus culminating the comprehensive compression sequence.
Harness the exceptional cooling prowess of water with Sanzhi (Henan) Compressor Co., Ltd's state-of-the-art water-cooled compressors. These units provide unmatched lubrication and extend the lifespan of wear-sensitive components significantly. As cooling water circulates meticulously through the system, it not only cleanses internal parts but also expertly dissipates heat from both the cylinder and compressed gas. This engineering brilliance leads to substantially lower exhaust temperatures and reduced power consumption, resulting in remarkable savings on operational costs. To ensure optimal performance, it's vital to remain vigilant and proactively manage any potential scaling within the water cooling system.
