Working Principle

In an ideal air compression setting, you would expect the power for single-stage compression to match the combined power for multiple stages. However, the reality of operational demands introduces higher power necessities due to influences like transmission power loss, bearing friction, and cooling effects from liquid viscosity. By skillfully reducing the compression ratio at each stage, multi-stage compression can significantly diminish power requirements compared to single-stage systems. This approach not only enhances operational efficiency but also markedly reduces excessive energy consumption.

The sophisticated two-stage screw air compressor boasts a dual rotary screw mechanism. Each stage integrates an active screw and its counterpart, the passive screw, with the active screw energizing the passive screw through a dedicated power transfer system. The first stage features a low-pressure screw assembly, while the second stage is fortified with a high-pressure screw assembly. Enveloping air films provide sealing for each screw, facilitating a seamless compression process through a well-orchestrated sequence of suction, pressurization, and exhaust.

First stage compression: In the commencement stage of the two-stage screw air compressor, a low-pressure screw assembly is deployed. The gas is drawn into the screw compression chamber via the meticulously designed suction valve, undergoing compression as the rotor whirls at high velocity. This preliminary compressed gas is then transferred to the second stage for further advancement in compression.

Second stage compression: As the process advances to the second stage, the gas enters a more constricted screw space, encountering increased pressures and heightened temperatures. The proficiently timed opening of the exhaust valve ensures the expulsion of high-pressure gases from the system, thus completing the intricate compression process.

Initially, natural air is filtered and blends with a precise amount of lubricating oil within the compression chamber. This mixture is compressed to an intermediate pressure and substantially cooled through interaction with oil mist in the cooling channel. The cooled gas then progresses to the second-stage rotor, where it undergoes secondary compression to reach the ultimate exhaust pressure. This comprehensive air compression cycle concludes as the meticulously compressed gas is released through the exhaust valve, marking the completion of the entire process.
