Working Principle
In the captivating realm of air compression, the quest for supreme efficiency in single-stage compression demands an impeccable alignment between power consumption and the total exertion observed in multi-stage compression systems. However, inefficiencies such as energy loss due to coupling, friction in bearings, and viscosity of the cooling liquid often plague real-world applications, leading to heightened power consumption. Ingeniously, multi-stage compression diminishes the compression ratio at each stage, effectively curtailing these inefficiencies, and remarkably reducing the overall power requirement when juxtaposed with single-stage compression. This strategy elegantly refines energy utilization and bolsters performance.
Introducing our groundbreaking Two-Stage Water-Cooled Permanent Magnet VFD Screw Air Compressor by Sanzhi, a marvel of engineering excellence featuring a dual-stage rotary screw mechanism. Each stage is meticulously designed with a dynamic active and passive screw pairing. The active screw propels the passive screw, driven by an external power source, ensuring seamless, uninterrupted operation. The first stage is equipped with a low-pressure rate screw group, while the second stage boasts a high-pressure rate screw group. Enveloped in a sealing air film, each screw masterfully compresses gas through a tri-phase process: suction, pressurization, and exhaust, guaranteeing unmatched energy efficiency and performance.
First Stage Compression: The journey begins with the low-pressure rate screw group expertly drawing in gas through a meticulously crafted suction valve. The gas is gradually compressed within the chamber, then deftly transferred to the second stage, orchestrated by the powerful rotation of the screw rotor. This stage artfully primes the gas for subsequent high-pressure compression, setting the stage for optimal performance and efficiency.
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 exhaust valve's opening, thus completing the compression cycle with finesse and precision, a true showcase of our advanced technological prowess.
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 expertly engineered mixture is compressed to interstage pressure and directed through a cooling channel, where it encounters a substantial oil mist that significantly reduces its temperature. The cooled gas then advances to the second stage for further compression, ultimately being released through the exhaust valve. This comprehensive sequence culminates in the successful completion of the compression process, ensuring exceptional results and operational excellence.
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, featuring a specialized air end that ingeniously incorporates 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 and setting a new standard in technology.
8) Innovative Internal Spray Curtain Cooling:Transform cooling efficiency with our groundbreaking internal spray curtain cooling method. Dramatically lowering compressed air temperature, this innovation closely approximates isothermal compression while minimizing pressure loss between stages, thereby elevating compression efficiency and ensuring superior performance.
9) Minimized Internal Leakage:Utilizing a two-stage compression technique, our design reduces the compression ratio for each stage, thereby minimizing internal leakage from high-pressure to low-pressure ends. This elevates volumetric efficiency, ensuring that your system runs smoothly and effectively.
10) Noise Reduction:The expertly designed two-stage compression significantly reduces the compression ratio, which results in a noteworthy decrease in operational noise, especially during unloading. Experience quieter operation without compromising on performance.
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. This ensures straightforward maintenance and convenient user operation, providing peace of mind and ease of use for our valued customers.
