Working Principle
In the intricate and ever-evolving world of air compression, achieving optimal efficiency in single-stage compression requires the energy expended to match the cumulative force of multi-stage compression. However, in actual operations, various factors such as energy loss at couplings, bearing friction, and the viscosity of cooling fluids often increase energy consumption. By strategically reducing the compression ratio at each subsequent stage, multi-stage compression effectively reduces these inefficiencies, resulting in a considerably reduced overall power requirement when compared to single-stage systems.
Presenting our revolutionary two-stage screw air compressor, masterfully crafted with a dual-stage rotary screw configuration. Each stage is equipped with a main and auxiliary screw, where the main screw dynamically drives the auxiliary screw with an external power source. The first stage is equipped with a low-pressure screw assembly, whereas the second stage has a high-pressure screw assembly. Each screw is enveloped by a protective air cushion, performing gas compression through three imperative phases: suction, pressurization, and exhaust.
First Stage Compression: This process begins with the low-pressure screw assembly efficiently compressing the gas. As gas enters the compression chamber through a suction valve, it is gradually compressed and then progresses to the second stage, driven by the continuous rotation of the screw rotor.
Second Stage Compression: Here, the gas moves into a confined screw chamber, undergoing compression under increased temperatures and pressures. As this phase concludes, the high-pressure gases are released once the exhaust valve opens, thereby completing the compression cycle.
The process initiates with ambient air being carefully filtered before it enters the initial compression stage, where it combines with a small amount of lubricating oil. This mixture is compressed to an interstage pressure and passes through a cooling layer, encountering a significant oil mist that greatly reduces its temperature. The cooled gas then proceeds to the second stage for additional compression, ultimately being expelled through the exhaust valve, thus completing the entire compression sequence.
Harnessing the outstanding cooling power of water, Sanzhi (Henan) Compressor Co., Ltd's water-cooled compressors deliver exceptional lubrication and extend the lifespan of components subject to friction. As cooling water circulates, it thoroughly cleanses internal parts and efficiently dissipates heat from the cylinder and compressed gas. This advanced engineering leads to significantly reduced exhaust temperatures and lowered power consumption, resulting in substantial operational cost savings. To ensure optimal performance, vigilant monitoring and proactive management of potential scaling issues within the water cooling system are essential.

This method significantly lowers compressed air temperature, aligning closely with isothermal compression and reducing pressure loss between stages, thereby enhancing compression efficiency.
9) Minimized Internal Leakage:Our pioneering two-stage compression technique decreases the compression ratio for each stage, thereby minimizing internal leakage from high to low-pressure ends and markedly boosting volumetric efficiency.
10) Noise Reduction:The innovative two-stage compression design considerably reduces the compression ratio, leading to a notable decrease in operational noise, particularly during unloading phases.
11) Simplified Maintenance and Service:Alongside the advanced screw air end, our two-stage compressor unit retains similar systems and structures to single-stage compressors, ensuring straightforward maintenance and ultimate user convenience.
