Working Principle
In an optimal air compression environment, the energy required for single-stage compression should theoretically match that for multi-stage compression. However, real-world conditions introduce challenges such as coupling transmission losses, bearing friction, and the cooling effects of liquid viscosity, which increase power consumption. To achieve peak efficiency, it is essential to minimize the compression ratio at each stage, ensuring the total power required for multi-stage compression is less than that for single-stage compression.
The two-stage screw air compressor from Sanzhi (Henan) Compressor Co., Ltd. is an engineering masterpiece, meticulously designed with an advanced dual rotary screw mechanism featuring both active and passive screws. The active screw, powered by an external transmission, drives the passive screw. This sophisticated 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 enveloped by a sealing air film, facilitating 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 starts the gas compression process. Gas is drawn into the screw compression chamber via 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 advances to the second-stage rotor for further compression to the final exhaust pressure. The process concludes as the compressor discharges the high-pressure gas through the exhaust valve, ensuring optimal performance and efficiency.
