Working Principle
In the captivating realm of air compression technology, achieving peak efficiency in single-stage compression demands that the power consumption accurately reflect the cumulative effort characteristic of advanced multi-stage systems. Real-world applications, however, often encounter inefficiencies, such as power loss due to coupling, bearing friction, and the viscosity of the coolant, which can escalate power usage. Ingeniously, multi-stage compression mitigates these inefficiencies by reducing the compression ratio at each stage, thus significantly lowering the total power requirement compared to single-stage compression, offering a markedly superior solution.
We are thrilled to introduce our cutting-edge two-stage screw air compressor, featuring an advanced dual-stage rotary screw mechanism. Each stage is expertly crafted with an active and a passive screw configuration. The active screw dynamically propels the passive screw via an external power source, ensuring seamless operation. The first stage is equipped with a low-pressure rate screw group, while the second stage is designed with a high-pressure rate screw group. Each screw is surrounded by a sealing air film, skillfully compressing the gas through three distinct stages: suction, pressurization, and exhaust, delivering unmatched performance and reliability.
First Stage Compression: The journey begins as the low-pressure rate screw group adeptly compresses the incoming gas. Through a precisely engineered suction valve, the gas is drawn into the compression chamber, where it undergoes a gradual and efficient transformation, driven by the relentless rotation of the screw rotor, before being seamlessly transferred to the second stage.
Second Stage Compression: In this vital phase, the gas is directed into a narrower screw space, subjected to intense compression at elevated temperatures and pressures. As the process reaches its zenith, the high-pressure gases are gracefully released from the system upon the opening of the exhaust valve, culminating the compression cycle with elegance and efficacy.
The sophisticated sequence begins with natural air being meticulously filtered before entering the initial compression stage. Here, it is expertly combined with a precise amount of lubricating oil. This amalgamation is compressed to interstage pressure, then navigated through a cooling channel, encountering a significant oil mist that dramatically reduces its temperature. The cooled gas advances to the second stage for further compression, ultimately being released through the exhaust valve, completing the comprehensive and meticulous compression cycle with precision and excellence.
Our water-cooled compressors masterfully leverage the formidable cooling power of water, ensuring unparalleled lubrication and dramatically extending the lifespan of components prone to wear. As the cooling water circulates, it meticulously purifies internal components while efficiently dispersing heat from both the cylinder and the compressed gas. This exceptional technique significantly lowers exhaust temperatures and power consumption, leading to outstanding operational cost efficiency. It is vital to routinely monitor and address any potential scaling issues within the water cooling system to sustain peak performance and extend longevity.

7) Unique Two-Stage Compression Air End:Our cutting-edge two-stage compression screw machine features a distinctive air end, combining both first-stage and second-stage compression rotors within a single casing. These rotors, powered by gears, achieve the optimal linear speed for each stage, significantly enhancing compression efficiency.
8) Innovative Internal Spray Curtain Cooling:Transform cooling efficiency with our trailblazing internal spray curtain cooling method. It significantly reduces the temperature of compressed air, approximating isothermal compression, while reducing pressure loss between stages, thus boosting compression efficiency.
9) Minimized Internal Leakage:Utilizing a two-stage compression approach, the compression ratio for each stage is lowered, thus minimizing internal leakage from high-pressure to low-pressure ends, thereby amplifying volumetric efficiency.
10) Noise Reduction:The two-stage compression design expertly reduces the compression ratio, resulting in a significant reduction in operational noise, especially during unloading.
11) Simplified Maintenance and Service:Beyond the screw air end, our two-stage compressor unit retains the familiar systems and structures of single-stage compressors, ensuring easy maintenance and user convenience.
