Working Principle
In an ideal scenario of air compression, the energy required for single-stage pressure transmission should match the total energy needed for multi-stage compression. However, real-world conditions introduce additional factors such as coupling transmission losses, bearing friction, and the cooling effects of liquid viscosity, all of which increase power demands. To achieve peak efficiency, minimizing the compression ratio at each stage is crucial, ensuring that the overall power required for multi-stage compression remains less than that needed for single-stage compression.
Introducing the highly advanced two-stage screw air compressor from Sanzhi (Henan) Compressor Co., Ltd., featuring a cutting-edge dual rotary screw mechanism. This system incorporates both active and passive screws, where the active screw, powered by an external transmission, drives the passive screw. The process starts with a low-pressure screw group in the first stage and advances to a high-pressure screw group in the second stage. Each screw is encased in a sealing air film, facilitating efficient gas compression through cycles of suction, pressurization, and exhaust during 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 effectively compresses the gas. This efficiently transfers the gas to the second stage for further processing.
Second Stage Compression: At this advanced phase, gas enters a narrower screw space, undergoing compression at considerably higher temperatures and pressures. The exhaust valve then opens, releasing the high-pressure gas from the system and completing the two-stage compression process.
Natural air is initially drawn into the first stage through an air filter, mixing with a small quantity 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 reducing its temperature. The cooled gas moves to the second-stage rotor for further compression to the final exhaust pressure. The entire sequence concludes with the high-pressure gas being discharged through the exhaust valve, ensuring optimal performance and efficiency.
