Working Principle
In an optimal air compression environment, the energy required for single-stage compression should theoretically be equivalent to that of multi-stage compression. However, real-world conditions introduce challenges such as coupling transmission losses, bearing friction, and the cooling effects of liquid viscosity, which elevate power consumption. To achieve peak efficiency, it is essential to minimize the compression ratio at each stage, thereby ensuring the total power required for multi-stage compression remains below that of single-stage compression.
The two-stage screw air compressor from Sanzhi (Henan) Compressor Co., Ltd. is an engineering masterpiece, meticulously designed with a cutting-edge dual rotary screw mechanism featuring both active and passive screws. The active screw, driven by an external transmission, powers the passive screw. This advanced 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, enabling efficient gas compression through sequential cycles of suction, pressurization, and exhaust during the screw's rotation.
First Stage Compression: In this 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, efficiently transferring it to the second stage for further processing.
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, thus completing the two-stage compression process.
Natural air is drawn into the first 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, significantly reducing its temperature. The cooled gas then progresses to the second-stage rotor for further compression to the final exhaust pressure. The process culminates as the compressor discharges the high-pressure gas through the exhaust valve, ensuring optimal performance and efficiency.
