Innovative Working Principle
In an optimal air compression scenario, the energy required for single-stage pressure transmission should mirror the total energy needed for multi-stage compression. However, practical conditions introduce variables like coupling transmission losses, bearing friction, and the cooling effects of liquid viscosity, all of which increase power demands. To achieve peak efficiency, it is crucial to minimize the compression ratio at each stage. This ensures that the overall power needed for multi-stage compression is less than that of single-stage compression.
The highly advanced two-stage screw air compressor from Sanzhi (Henan) Compressor Co., Ltd. integrates a cutting-edge dual rotary screw mechanism. Featuring both active and passive screws, the active screw is driven by an external transmission that powers the passive screw. This exceptional system begins with a low-pressure screw group in the first stage and progresses to a high-pressure screw group in the second stage. Each screw is enveloped by a sealing air film, facilitating gas compression through sequential 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 efficiently compresses the gas, transferring it seamlessly to the second stage for further processing.
Second Stage Compression: At this advanced phase, the gas enters a narrower screw space and undergoes compression at significantly elevated temperatures and pressures. The exhaust valve then opens, releasing the high-pressure gas from the system, thus completing the sophisticated two-stage compression process.
Natural air is initially drawn into the first stage through an air filter, where it blends with a precise 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 then advances to the second-stage rotor for additional compression to the final exhaust pressure. The entire sequence concludes as the compressor discharges the high-pressure gas through the exhaust valve, guaranteeing optimal performance and efficiency.
