Working Principle

In the realm of air compression, the ideal process suggests that the power for single-stage pressure is equivalent to the combined power for multi-stage compression. Yet, reality introduces additional power demands due to factors like transmission power loss, bearing friction, and the cooling effects of liquid viscosity. By strategically minimizing the compression ratio at each stage, this advanced technology enables a significantly reduced total power requirement for multi-stage compression compared to its single-stage counterpart, thereby elevating efficiency and cutting down on superfluous power usage.

The sophisticated two-stage screw air compressor is designed with a dual rotary screw system. In each stage, there exists an active screw coupled with a passive screw, where the active screw drives the passive one through an adept external power transmission mechanism. The first stage implements a low-pressure screw group, while the second stage harnesses a high-pressure screw group. Ingenious sealing air films envelop each screw, facilitating the compression journey through three pivotal phases: suction, pressurization, and exhaust.

First Stage Compression: The journey begins with the initial stage of the two-stage screw air compressor, leveraging a low-pressure screw group. In this phase, gas smoothly enters the screw compression chamber via the strategically engineered suction valve and undergoes compression as the screw rotor whirls at a stellar speed. This newly compressed gas is then seamlessly transferred to the second stage for further refinement.

Second Stage Compression: As the narrative continues, in the second stage, the gas finds itself in a more compact screw space, where it faces elevated pressures and temperatures. The carefully timed opening of the exhaust valve allows the high-pressure gases to be expelled from the system, thus concluding the sophisticated compression process.

The air compression saga begins as natural air journeys through the air filter, blending with a precise amount of lubricating oil in the compression chamber. This meticulous mixture is compressed to interstage pressure and dramatically cooled as it engages with oil mist in the cooling channel. Subsequently, the cooled gas enters the second-stage rotor, undergoing a secondary compression to reach the ultimate exhaust pressure. This comprehensive process reaches its zenith as the compressed gas is expelled through the exhaust valve, completing the entire air compression cycle with precision and efficiency.
