Working Principle
While ideal air compression would equalize the energy demands of single-stage and multi-stage compression, real-world conditions introduce complexities. Coupling transmission losses, bearing friction, and the cooling effects of liquid viscosity increase power requirements. To optimize efficiency, it's crucial to minimize the compression ratio at each stage. This ensures that multi-stage compression demands less overall power than single-stage compression.
Our two-stage screw air compressor boasts a sophisticated design featuring a dual rotary screw mechanism with both active and passive screws. The active screw, driven externally, powers the passive screw. Beginning with a low-pressure screw group in the first stage and then transitioning to a high-pressure screw group in the second stage, each screw is encapsulated by a sealing air film. This design facilitates efficient gas compression through cycles of suction, pressurization, and exhaust during rotation.
First Stage Compression: In this crucial initial phase, the low-pressure screw group initiates gas compression. Gas enters the screw compression chamber via the suction valve, where the rapid rotor rotation compresses the gas and seamlessly transfers it to the second stage.
Second Stage Compression: In this advanced phase, gas is compressed in a narrower screw space at significantly higher temperatures and pressures. The exhaust valve subsequently opens, releasing the compressed high-pressure gas from the system.
The compression process starts with natural air being drawn into the initial stage through an air filter. Here, it mixes with a small amount of lubricating oil in the compression chamber. The gas is compressed to interstage pressure and then cooled via an oil mist in the cooling channel, significantly reducing its temperature. The cooled gas then proceeds to the second-stage rotor for further compression to the final exhaust pressure. The process concludes with the high-pressure gas being discharged through the exhaust valve.
