Working Principle
In a vision of air compression excellence, the power required for single-stage compression is ideally matched by the combined power necessary for multiple stages. Yet, the complexities of real-world operations necessitate more power because of elements like transmission power loss, bearing friction, and the cooling effects arising from liquid viscosity. By skillfully minimizing the compression ratio at each stage, multi-stage compression can demand significantly less power than single-stage compression, thereby enhancing efficiency and reducing unnecessary energy consumption.
The cutting-edge two-stage screw air compressor boasts a sophisticated dual rotary screw system. Each stage consists of an active screw and a passive screw, with the active screw driving the passive screw via an external power transfer system. The first stage is equipped with a low-pressure screw assembly, while the second stage features a high-pressure screw assembly. Sealing air films envelop the screws, facilitating the compression process through three essential phases: suction, pressurization, and exhaust.
First stage compression: In the initial phase of the two-stage screw air compressor, a low-pressure screw assembly is employed. The gas is drawn into the screw compression chamber through the suction valve, compressed as the rotor rotates at high speed, and then directed to the second stage for additional compression.
Second stage compression: At the second phase, the gas enters a more confined screw chamber, where it encounters increased pressures and temperatures. The exhaust valve then opens, expelling the high-pressure gases from the system, thus completing the compression cycle.
At the onset, natural air is channeled through the air filter and merges with a trace of lubricating oil within the compression chamber. This mixture is compressed to an intermediate pressure and then significantly cooled upon contact with oil mist in the cooling channel. The cooled gas proceeds to the second-stage rotor, undergoing secondary compression to achieve the final exhaust pressure. The entire cycle concludes as the compressed gas is emitted through the exhaust valve, completing the comprehensive air compression cycle.
