Working Principle
In an ideal air compression scenario, the energy required for single-stage pressure transmission should be equal to the total energy required for multi-stage compression. However, real-world conditions introduce factors such as coupling transmission losses, bearing friction, and the cooling effects of liquid viscosity, all of which increase power demands. To achieve optimal efficiency, it is crucial to minimize the compression ratio at each stage, ensuring that the overall power needed for multi-stage compression is less than that of single-stage compression.
The two-stage screw air compressor is meticulously designed with an advanced dual rotary screw mechanism. This includes both active and passive screws, where 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 encased by a sealing air film, allowing gas compression through consecutive cycles of suction, pressurization, and exhaust during the screw's rotation.
First Stage Compression: In this crucial initial phase, the low-pressure screw group begins 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 narrower 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 is cooled in the cooling channel through contact with oil mist, significantly lowering its temperature. The cooled gas then moves 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.
