Working Principle
In the intricate realm of air compression, achieving unparalleled efficiency during single-stage compression requires the energy applied to emulate the cumulative force of multi-stage compression. However, in practical applications, various factors such as power loss at couplings, bearing friction, and cooling liquid viscosity often escalate energy usage. By strategically minimizing the compression ratio at each consecutive stage, our multi-stage compression significantly diminishes these inefficiencies, resulting in a substantially lower overall power requirement compared to single-stage systems.
Introducing our groundbreaking two-stage screw air compressor, designed with an advanced dual-stage rotary screw configuration. Within each stage, a master and supporting screw pair work in unison, with the master screw effectively driving the supporting screw through an external power linkage. The first stage features a low-pressure rate screw assembly, while the second stage is equipped with a high-pressure rate screw assembly. Each screw is enveloped in a protective air film, meticulously executing gas compression through three essential phases: suction, pressurization, and exhaust.
First Stage Compression: The process initiates with the low-pressure rate screw group adeptly compressing the gas. As the gas enters the compression chamber via a suction valve, it undergoes steady compression, subsequently transitioning to the second stage propelled by the persistent rotation of the screw rotor.
Second Stage Compression: At this stage, the gas enters a confined screw space, undergoing compression at elevated temperatures and pressures. This phase culminates as the high-pressure gases are expelled from the system when the exhaust valve opens, thus completing the compression cycle.
The process begins with ambient air undergoing precise filtration before entering the initial compression stage, where it blends with a minimal amount of lubricating oil. This mixture is compressed to an interstage pressure and travels through a cooling conduit, encountering a significant oil mist that substantially lowers its temperature. The cooled gas then advances to the second stage for additional compression, culminating in its expulsion through the exhaust valve, thereby completing 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.

Equipped with a unique air end, it combines first-stage and second-stage compression rotors within one casing. 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.
