Working Principle
In the sophisticated arena of air compression technology, achieving unmatched efficiency in single-stage compression requires energy usage comparable to the combined power of multi-stage systems. However, real-world impediments such as energy dissipation at couplings, friction from bearings, and the viscosity inherent in cooling fluids often escalate the energy demand. Multi-stage compression masterfully overcomes these hurdles by diminishing the compression ratio at each level, thus significantly reducing the overall power requirement compared to single-stage systems.
Presenting our revolutionary two-stage screw air compressor, a paragon of engineering excellence featuring a dual-stage rotary screw design. Central to this innovation is a complex mechanism where each stage consists of a primary and secondary screw. The primary screw dynamically powers the secondary screw, supported by an external energy source. The initial stage boasts a low-pressure screw assembly, seamlessly succeeded by a high-pressure screw assembly in the subsequent tier. Each screw is meticulously encased in a protective air cushion, expertly executing gas compression through three critical phases: suction, pressurization, and exhaust.
First Stage Compression: The procedure initiates with the adept compression of gas by the low-pressure screw assembly. As the gas is drawn into the compression chamber through a suction valve, it undergoes meticulous compression, subsequently transitioning seamlessly to the second stage, propelled by the screw rotor's continuous rotation.
Second Stage Compression: In this pivotal phase, the gas enters a meticulously sealed screw chamber, where it is compressed under rising temperatures and pressures. Upon the conclusion of this stage, the high-pressure gases are expelled from the system with the opening of the exhaust valve, thereby completing the compression cycle.
The journey begins with ambient air being meticulously filtered before entering the initial compression stage, where it converges with a minute amount of lubricating oil. This mixture is compressed to an interstage pressure, navigating through a cooling conduit and encountering a substantial oil mist that significantly lowers its temperature. The cooled gas then progresses to the second stage for further compression, ultimately being discharged through the exhaust valve, thus culminating the comprehensive compression sequence.
Harnessing the remarkable cooling efficacy of water, Sanzhi (Henan) Compressor Co., Ltd's water-cooled compressors ensure unparalleled lubrication and significantly prolong the lifespan of friction-prone components. As cooling water circulates through the system, it meticulously cleanses internal parts and expertly dissipates heat from both the cylinder and compressed gas. This meticulous engineering results in dramatically reduced exhaust temperatures and diminished power consumption, culminating in extraordinary savings in operational expenses. To maintain peak performance, diligent monitoring and proactive management of potential scaling issues within the water cooling system are crucial.

This method significantly lowers compressed air temperature, aligning closely with isothermal compression and reducing pressure loss between stages, thus boosting compression efficiency.
9) Minimized Internal Leakage:Our pioneering two-stage compression technique carefully reduces the compression ratio for each stage, effectively minimizing internal leakage from high to low-pressure ends, and significantly enhancing volumetric efficiency.
10) Noise Reduction:The ingenious two-stage compression design effectively lowers the compression ratio, resulting in a noticeable decrease in operational noise, particularly during unloading phases.
11) Simplified Maintenance and Service:Besides the advanced screw air end, our two-stage compressor unit preserves similar systems and structures to single-stage compressors, ensuring maintenance is straightforward and user convenience is maximized.
