Working Principle
In an ideal air compression scenario, the power required for single-stage pressure transmission equals the cumulative power for multi-stage compression. However, during real-world operations, various factors such as coupling transmission losses, bearing friction, and the cooling effects of liquid viscosity increase the power demand. To enhance efficiency, it is vital 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.
The two-stage screw air compressor boasts a sophisticated dual rotary screw mechanism, seamlessly integrating both active and passive screws. The active screw, driven externally, powers the passive screw. The process begins with the first stage using a low-pressure screw group, transitioning to a high-pressure screw group in the second stage. Each screw is enveloped by a sealing air film, facilitating gas compression through coordinated suction, pressurization, and exhaust cycles during screw rotation.
First Stage Compression: In this crucial initial phase, the low-pressure screw group kick-starts the gas compression process. Gas is drawn into the screw compression chamber via the suction valve. The swift rotation of the screw rotor compresses the gas effectively, preparing it for the advanced second stage.
Second Stage Compression: At this advanced stage, gas enters a more confined screw space where it undergoes compression at significantly higher temperatures and pressures. The exhaust valve then opens, efficiently releasing the high-pressure gas from the system.
Natural air is initially drawn into the first stage through an air filter. Here, it mixes with a minute amount of lubricating oil within the compression chamber. The gas is compressed to interstage pressure and then cooled in the cooling channel through contact with oil mist, significantly lowering its temperature. This cooled gas then advances to the second-stage rotor for further compression, reaching the final exhaust pressure. The process culminates as the compressor discharges the high-pressure gas through the exhaust valve.
