Working Principle

In the realm of ideal air compression, a singular-stage transmission would demand power equivalent to all cumulative power needed for a multi-stage process. Yet, reality dictates greater power consumption due to inevitable factors like transmission power loss, bearing friction, and the cooling effects of liquid viscosity. By strategically diminishing the compression ratio for each stage, the overall power requirement for multi-stage compression can be significantly lower, surpassing single-stage efficiency and curtailing superfluous energy consumption.

The cutting-edge two-stage screw air compressor is equipped with a sophisticated dual rotary screw system. Each compression stage comprises an active and a passive screw, the active one seamlessly driving the passive through a refined external power transmission mechanism. Initiating with a low-pressure screw group in the first stage, it gracefully transitions to a high-pressure screw group in the second. The formation of sealing air films around every screw is pivotal, orchestrating the compression journey through three integral phases: suction, pressurization, and exhaust.

First stage compression: This pivotal initial stage in the two-stage screw air compressor is empowered by a low-pressure screw group. Here, the gas is ingeniously channeled into the screw compression chamber through the suction valve, where it undergoes swift compression as the screw rotor whirls with high velocity. This compressed gas is then seamlessly passed on to the subsequent stage for further enhancement.

Second stage compression: As the gas advances into the second stage, it encounters a more compact screw space, where it is subjected to intensified pressures and soaring temperatures. The strategic opening of the exhaust valve facilitates the expulsion of high-pressure gases, culminating in the completion of the compression process.

The journey of natural air commences as it gracefully enters through the air filter, harmoniously blending with a trace of lubricating oil within the compression chamber. As this fusion is compressed to interstage pressure, it undergoes significant cooling by mingling with oil mist in the cooling channel. Subsequently, the cooled mixture enters the second-stage rotor, embarking on a secondary compression voyage to attain the final exhaust pressure. The grand finale of this cycle is marked by the compressed gas being elegantly expelled through the exhaust valve, completing the intricate air compression cycle with finesse.
