Working Principle
In an ideal air compression setting, the energy needed for single-stage compression aligns with the cumulative energy required for multiple stages. Yet, in practical applications, operations demand more power due to factors like transmission losses, bearing friction, and cooling effects from liquid viscosity. By skillfully reducing the compression ratio at each stage, multi-stage compression can demand significantly less power than single-stage compression. This approach not only enhances efficiency but also reduces unnecessary energy usage, offering a more sustainable and cost-effective solution.
The cutting-edge two-stage screw air compressor integrates a dual rotary screw system. Each stage consists of an active screw and a passive screw, where the active screw drives the passive screw through an external power transfer mechanism. The first stage features a low-pressure screw assembly, and the second stage is equipped with a high-pressure screw assembly. Sealing air films envelop each screw, facilitating the compression sequence through three distinct phases: suction, pressurization, and exhaust, ensuring a seamless and efficient operation.
First Stage Compression: At the onset of the two-stage screw air compressor operation, a low-pressure screw assembly is deployed. Gas is drawn into the screw compression chamber through the suction valve, where the rotor compresses it as it spins at high speed. This compressed gas is then dispatched to the second stage for further compression, ensuring ongoing operational continuity.
Second Stage Compression: During the second stage, the gas enters a more compact screw space, subjected to heightened pressures and temperatures. The exhaust valve then opens, releasing the high-pressure gases from the system, effectively completing the compression process and ensuring the system's reliability and performance.
Initially, ambient air flows through the air filter, merging with a trace of lubricating oil within the compression chamber. This mixture is compressed to an intermediate pressure and then significantly cooled through contact with oil mist in the cooling channel. The cooled gas enters the second-stage rotor, undergoing secondary compression to attain the final exhaust pressure. This comprehensive cycle concludes as the compressed gas is expelled through the exhaust valve, marking the completion of the full air compression cycle, ensuring peak efficiency and reliability.
