Working Principle
In the intricate and ever-evolving realm of air compression, the quest for optimal efficiency in single-stage compression necessitates that the energy exerted mirrors the aggregated power of multi-stage compression. Yet, in real-world scenarios, numerous elements such as energy dissipation at couplings, bearing resistance, and the thickness of cooling agents often amplify energy usage. By astutely diminishing the compression ratio at each advanced stage, multi-stage compression deftly curtails these inefficiencies, resulting in a markedly reduced total power demand compared to single-stage configurations.
Introducing our revolutionary two-stage screw air compressor, masterfully crafted with an innovative dual-stage rotary screw arrangement. Each stage encompasses a main and secondary screw, where the main screw dynamically drives the secondary screw via an external power source. In the first stage, a low-pressure screw ensemble is showcased, while the second stage features a high-pressure screw ensemble. Encased by a protective air cushion, each screw proficiently compresses the gas through three essential phases: suction, pressurization, and exhaust.
First Stage Compression: The process commences with the low-pressure screw assembly effectively compressing the gas. Upon entering the compression chamber through a suction valve, the gas is gradually compressed and then transitions to the second stage, driven by the relentless rotation of the screw rotor.
Second Stage Compression: At this juncture, the gas is channeled into a confined screw chamber, experiencing compression under heightened temperatures and pressures. As this phase concludes, the high-pressure gases are liberated from the system as the exhaust valve opens, thereby completing the compression cycle.
The process embarks with ambient air being meticulously filtered before it enters the initial compression stage, merging with a minimal amount of lubricating oil. This mixture is compressed to an interstage pressure and navigates through a cooling conduit, encountering a notable oil mist that substantially decreases its temperature. The cooled gas proceeds to the second stage for further compression, ultimately being expelled through the exhaust valve, thus fulfilling the comprehensive compression sequence.
Discover the pinnacle of cooling technology with Sanzhi (Henan) Compressor Co., Ltd's water-cooled compressors. By harnessing the impressive cooling properties of water, these compressors guarantee exceptional lubrication, drastically prolonging the lifespan of components sensitive to friction. As the cooling water circulates, it meticulously purifies internal parts and expertly dissipates heat from both the cylinder and compressed gas. This cutting-edge engineering results in significantly lower exhaust temperatures and reduced power consumption, leading to substantial savings in operational costs. To uphold peak performance, vigilant monitoring and proactive management of potential scaling issues within the water cooling system are imperative.
