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 features an advanced dual rotary screw mechanism, integrating both active and passive screws. The active screw, driven by an external transmission, propels the passive screw. The system starts 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, which enables the gas compression through sequential suction, pressurization, and exhaust cycles during the screw's rotation.
First Stage Compression: In this initial phase, the low-pressure screw group initiates 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, transferring it effectively 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 mixes with a small 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, which significantly lowers its temperature. The cooled gas proceeds to the second-stage rotor for further compression to the final exhaust pressure. The entire process concludes as the compressor discharges the high-pressure gas through the exhaust valve.
