Working Principle
In the captivating domain of air compression, achieving the pinnacle of efficiency in single-stage compression requires that the power consumption impeccably aligns with the total exertion observed in multi-stage compression systems. Unfortunately, real-world applications often encounter inefficiencies, such as energy loss due to coupling, friction in bearings, and the viscosity of the cooling liquid, all contributing to elevated power consumption. Ingeniously, multi-stage compression reduces the compression ratio at each stage, effectively mitigating these inefficiencies, and markedly lowering the overall power requirement when contrasted with single-stage compression. This strategy elegantly optimizes energy use and enhances performance.
Introducing our groundbreaking two-stage screw air compressor, a marvel of engineering that features a dual-stage rotary screw mechanism. Each stage is meticulously crafted with an active and a passive screw. The active screw propels the passive screw through an external power source, ensuring seamless operation. The first stage is equipped with a low-pressure rate screw group, whereas the second stage boasts a high-pressure rate screw group. Enveloped by a sealing air film, each screw masterfully compresses the gas through a tri-phase process: suction, pressurization, and exhaust, guaranteeing unmatched efficiency.
First Stage Compression: The journey begins with the low-pressure rate screw group expertly drawing in the gas through a meticulously crafted suction valve. The gas is gradually compressed within the chamber and deftly transferred to the second stage, all orchestrated by the powerful rotation of the screw rotor. This stage ensures that the gas is prepared for the subsequent high-pressure compression, setting the stage for optimal performance.
Second Stage Compression: In this pivotal phase, the gas is skillfully channeled into a more confined screw space, where it undergoes compression at elevated temperatures and pressures. As the process reaches its zenith, the high-pressure gases are gracefully expelled from the system upon the opening of the exhaust valve, thus completing the compression cycle with finesse and precision, showcasing our advanced technology.
The intricate process commences with natural air being meticulously filtered before entering the initial compression stage. Here, it is precisely blended with a minimal amount of lubricating oil. This mixture is compressed to interstage pressure and expertly directed through a cooling channel, where it encounters a substantial amount of oil mist that significantly reduces its temperature. The cooled gas then proceeds to the second stage for further compression, ultimately being released through the exhaust valve. This comprehensive and thorough sequence culminates in the successful completion of the compression process, ensuring exceptional results.
Water-cooled compressors effortlessly harness the remarkable cooling power of water, offering unparalleled lubrication while significantly extending the lifespan of wear-prone components. As the cooling water circulates, it meticulously purifies internal parts and efficiently dissipates heat from both the cylinder and compressed gas. This superior cooling approach dramatically lowers exhaust temperatures and power usage, resulting in substantial operational cost savings. For optimal performance and prolonged longevity, it is crucial to regularly monitor and manage any potential scaling issues within the water cooling system.

7) Unique Two-Stage Compression Air End:Introducing our revolutionary two-stage compression screw machine with a specialized air end, incorporating both first and second-stage compression rotors within a single casing. These rotors, operating via gears, reach the ideal linear speed for each stage, significantly enhancing compression efficiency.
8) Innovative Internal Spray Curtain Cooling:Transform cooling efficiency with our groundbreaking internal spray curtain cooling method. It dramatically lowers compressed air temperature, closely approximating isothermal compression, while minimizing pressure loss between stages, thereby elevating compression efficiency.
9) Minimized Internal Leakage:Utilizing a two-stage compression technique, the compression ratio for each stage is reduced, thus minimizing internal leakage from high-pressure to low-pressure ends and elevating volumetric efficiency.
10) Noise Reduction:The expertly designed two-stage compression significantly reduces the compression ratio, resulting in a noteworthy decrease in operational noise, especially during unloading.
11) Simplified Maintenance and Service:Apart from the screw air end, our two-stage compressor unit retains the familiar systems and structures of single-stage compressors, ensuring straightforward maintenance and convenient user operation.
