Working Principle
In the fascinating world of air compression, the quest for perfect efficiency in single-stage compression demands that power consumption is precisely harmonized with the force typically observed in multi-stage systems. However, in practical applications, inefficiencies like coupling energy loss, bearing friction, and cooling liquid viscosity often lead to increased power consumption. Ingeniously, multi-stage compression offers a solution by reducing the compression ratio in each stage, effectively minimizing these inefficiencies and significantly lowering the overall power requirement compared to single-stage compression. This strategic approach optimizes energy utilization and remarkably enhances performance.
Unveiling our revolutionary two-stage screw air compressor, a masterpiece of innovation that incorporates a dual-stage rotary screw mechanism. Each stage is precisely designed with an active and passive screw, where the active screw drives the passive screw through an external power source, ensuring smooth and efficient operation. The first stage features a low-pressure rate screw group, while the second stage is equipped with a high-pressure rate screw group. Each screw, surrounded by a sealing air film, masterfully compresses the gas through a three-phase process of suction, pressurization, and exhaust, guaranteeing unparalleled efficiency.
First Stage Compression: The process begins with the low-pressure rate screw group expertly drawing in the gas through a precisely engineered suction valve. The gas is gently compressed within the chamber and skillfully transferred to the second stage, all orchestrated by the robust rotation of the screw rotor. This stage ensures the gas is adequately prepared for the upcoming high-pressure compression, laying the groundwork for peak performance.
Second Stage Compression: In this critical phase, the gas is adeptly guided into a more compact screw space, where it undergoes compression at higher temperatures and pressures. As the process culminates, the high-pressure gases are smoothly expelled from the system with the opening of the exhaust valve, thus completing the compression cycle with elegance and precision, highlighting our cutting-edge technology.
The complex process begins with natural air being carefully filtered before entering the initial compression stage. Here, it is precisely mixed with a small amount of lubricating oil. This mixture is compressed to interstage pressure and deftly directed through a cooling channel, where it encounters a substantial oil mist that significantly lowers its temperature. The cooled gas then advances to the second stage for further compression, ultimately being released through the exhaust valve. This comprehensive and meticulous sequence results in the successful completion of the compression process, ensuring outstanding results.
Water-cooled compressors leverage the incredible cooling power of water with seamless efficiency, offering unmatched lubrication and substantially prolonging the life of components susceptible to wear. As the cooling water circulates, it meticulously cleanses internal parts and effectively disperses heat from both the cylinder and the compressed gas. This advanced cooling technology drastically reduces exhaust temperatures and power consumption, translating into significant operational cost reductions. To maintain optimal performance and extend lifespan, it is essential to routinely monitor and address any potential scaling issues within the water cooling system.

It significantly lowers compressed air temperature, nearing isothermal compression, and minimizes pressure loss between stages, thereby enhancing compression efficiency.
9) Minimized Internal Leakage:Our two-stage compression technique reduces the compression ratio for each stage, thereby minimizing internal leakage from high-pressure to low-pressure ends and enhancing volumetric efficiency.
10) Noise Reduction:The expertly crafted two-stage compression notably reduces the compression ratio, resulting in a significant decrease in operational noise, particularly 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 convenient user operation.
