Working Principle
In the sophisticated world of air compression technology, achieving ideal efficiency in single-stage pressure transmission is theoretically possible. However, in real-world applications, power requirements increase due to factors such as coupling transmission losses, bearing friction, and the cooling effect of liquid viscosity. For superior performance, reducing the compression ratio at each stage is critical. This ensures that the total power needed for multi-stage compression is lower than that for single-stage compression.
The Sanzhi 132kw Two-Stage Screw Air Compressor stands out with its state-of-the-art dual rotary screw system. This advanced mechanism uses both active and passive screws, where the active screw is driven by an external transmission to rotate the passive screw. The system begins with a low-pressure screw assembly in the first stage and progresses to a high-pressure screw assembly in the second stage. Each screw is enveloped by a sealing air film, which aids in gas compression through successive suction, pressurization, and exhaust phases during the screw's rotation.
First Stage Compression: In this crucial initial phase, the low-pressure screw assembly takes the lead in starting the gas compression. Gas flows into the screw compression chamber through the suction valve, where the rapid rotation of the screw rotor compresses the gas efficiently, preparing it for the next stage.
Second Stage Compression: In this advanced phase, the gas is subjected to a more confined screw space, experiencing significantly higher temperatures and pressures. The meticulously designed exhaust valve then opens, allowing the release of the high-pressure gas from the system.
Natural air is initially drawn into the first stage through an air filter, where it combines with a small amount of lubricating oil within the compression chamber. Here, the gas is compressed to an interstage pressure and subsequently cooled by oil mist in the cooling channel, significantly reducing its temperature. This cooled gas then advances to the second-stage rotor for further compression, achieving the final exhaust pressure. The process culminates as the compressor discharges the high-pressure gas through the exhaust valve.
