Working Principle
In an optimal air compression scenario, the power required for single-stage pressure transmission should be equivalent to the cumulative power needed for multi-stage compression. However, in practical applications, various factors such as coupling transmission losses, bearing friction, and the cooling effects of liquid viscosity tend to increase the power demand. To maximize efficiency, it is crucial to minimize the compression ratio at each stage, thereby ensuring that the overall power required for multi-stage compression remains lower than that of single-stage compression.
The two-stage screw air compressor is engineered with a sophisticated dual rotary screw mechanism, featuring both active and passive screws. The active screw, driven by an external transmission, powers the passive screw. The system begins with a low-pressure screw group in the first stage, followed by a high-pressure screw group in the second stage. Each screw is enveloped by a sealing air film, enabling 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 and efficiently transfers 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 initially drawn into the first stage through an air filter, where it blends 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 through contact with oil mist, significantly lowering its temperature. The cooled gas then 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.
