Revolutionary Working Principle
In an ideal air compression scenario, the efficiency of single-stage pressure transmission equals the cumulative efficiency of multi-stage compression. However, real-world operations introduce various inefficiencies such as coupling transmission losses, bearing friction, and the cooling effects of liquid viscosity, which elevate power demand. To maximize efficiency, it is crucial to minimize the compression ratio at each stage, ensuring that the overall power required for multi-stage compression remains lower than that of single-stage compression.
Our cutting-edge two-stage screw air compressor boasts an advanced dual rotary screw mechanism, integrating both active and passive screws. The active screw, driven by an external transmission, powers the passive screw. The system commences with a low-pressure screw group in the first stage, followed by a high-pressure screw group in the second stage. Each screw is encased by a sealing air film, facilitating gas compression through a seamless cycle of suction, pressurization, and exhaust during the screw's rotation.
First Stage Compression: In this initial phase, the low-pressure screw group kicks off the gas compression process. Gas is drawn into the screw compression chamber through the suction valve, where the rapid rotation of the screw rotor compresses the gas, efficiently transferring it to the second stage.
Second Stage Compression: At this advanced stage, gas enters a more confined screw space and undergoes compression at significantly higher temperatures and pressures. The exhaust valve then opens, releasing the high-pressure gas from the system.
Natural air is first drawn into the initial stage through an air filter, where it is mixed with a precise amount of lubricating oil in the compression chamber. The gas is then compressed to interstage pressure and cooled in the cooling channel by contact with oil mist, significantly reducing its temperature. The cooled gas proceeds to the second-stage rotor for further compression to the final exhaust pressure. The entire process culminates as the compressor discharges the high-pressure gas through the exhaust valve.
