Working Principle
In the highly intricate world of air compression, the quest for ultimate efficiency during single-stage compression requires that the energy exerted mirrors the collective power of multi-stage compression. Yet, in the practical realm, several factors such as power dissipation at couplings, friction in bearings, and the viscosity of cooling liquids often contribute to increased energy consumption. By intelligently reducing the compression ratio at each sequential stage, multi-stage compression effectively alleviates these inefficiencies, achieving a remarkably reduced total power demand in contrast to single-stage systems.
We proudly present our revolutionary two-stage screw air compressor, ingeniously designed with a dual-stage rotary screw configuration. Each stage houses a master and a supporting screw, where the master screw dynamically drives the supporting screw through an external power source. The first stage boasts a low-pressure rate screw assembly, while the second stage features a high-pressure rate screw assembly. Each screw is enveloped by a protective air film, meticulously compressing the gas through three pivotal phases: suction, pressurization, and exhaust.
First Stage Compression: The process begins with the low-pressure rate screw group efficiently compressing the gas. As gas enters the compression chamber through a suction valve, it undergoes gradual compression, subsequently transitioning to the second stage under the relentless rotation of the screw rotor.
Second Stage Compression: At this juncture, the gas moves into a confined screw space, experiencing compression at heightened temperatures and pressures. The conclusion of this phase sees the high-pressure gases being discharged from the system as the exhaust valve opens, thereby completing the compression cycle.
The journey commences with ambient air being precisely filtered before entering the initial compression stage, where it amalgamates with a slight amount of lubricating oil. This mixture is compressed to an interstage pressure and travels through a cooling conduit, where it encounters a significant oil mist that substantially reduces its temperature. The cooled gas then proceeds to the second stage for further compression, finally being expelled through the exhaust valve, thus fulfilling the comprehensive compression sequence.
Harnessing the superior cooling powers of water, our water-cooled compressors guarantee exceptional lubrication and an extended lifespan for components prone to friction. As cooling water circulates, it not only cleanses internal parts but also efficiently dissipates heat from both the cylinder and compressed gas. This meticulous process significantly reduces exhaust temperatures and power consumption, leading to remarkable savings in operational costs. To uphold peak performance, regular monitoring and proactive management of potential scaling issues within the water cooling system are essential.

These rotors function via gears to attain optimal linear speed for each stage, dramatically enhancing compression efficiency.
8) Innovative Internal Spray Curtain Cooling:Introducing our groundbreaking internal spray curtain cooling approach, which offers unparalleled cooling proficiency. This technique substantially lowers compressed air temperature, closely aligning with isothermal compression, and reduces pressure loss between stages, thereby boosting compression efficiency.
9) Minimized Internal Leakage:Our pioneering two-stage compression approach reduces the compression ratio for each stage, thereby minimizing internal leakage from high to low-pressure ends and significantly enhancing volumetric efficiency.
10) Noise Reduction:The innovative two-stage compression design notably lowers the compression ratio, leading to a significant decrease in operational noise, especially during unloading phases.
11) Simplified Maintenance and Service:Beyond the advanced screw air end, our two-stage compressor unit retains analogous systems and structures to single-stage compressors, ensuring straightforward maintenance and ultimate user convenience.
