Working Principle
In the realm of air compression, the theoretical requirement for power in a single-stage pressure transmission matches the combined power needed for multi-stage compression. Yet, reality paints a different picture, where additional energy is demanded due to factors like transmission power loss, friction from bearings, and the cooling effects brought on by liquid viscosity. Optimizing the compression ratio at each stage allows for a significant reduction in total power use in multi-stage systems compared to single-stage ones. This approach not only boosts efficiency but also cuts down on wasted energy.
The industrial marvel of the two-stage screw air compressor lies in its innovative dual rotary screw design. Each operational stage is equipped with an active and passive screw duo, where the active screw propels its passive counterpart via an external power transmission system. Commencing with a low-pressure screw group in the first stage, it advances to a high-pressure screw group in the second stage. The intricate dance of sealing air films around each screw orchestrates the compression journey through the critical phases of suction, pressurization, and exhaust.
First stage compression: At the forefront of the two-stage screw air compressor, the low-pressure screw group kicks off the initial stage of compression. It all begins as gas flows into the screw compression chamber through the suction valve, where it meets the swift spinning screw rotor. This high-speed rotation compresses the gas, preparing it for its next phase of journey towards the second stage.
Second stage compression: As the gas transitions into the second stage, it finds itself within a tightened screw space, encountering heightened pressures and increased temperatures. With the opening of the exhaust valve, the system efficiently releases these high-pressure gases, marking the culmination of the comprehensive compression process.
The journey of natural air in our compressor begins as it flows through the air filter, blending seamlessly with a touch of lubricating oil in the compression chamber. This fusion is compressed to an interstage pressure level, then subjected to substantial cooling through interactions with oil mist in the cooling channel. The refreshed gas proceeds to the second-stage rotor, where it undergoes a secondary, thorough compression to reach its ultimate exhaust pressure. The process reaches its zenith as the compressed gas exits through the exhaust valve, completing a meticulous cycle of air compression.
