Working Principle
In the complex arena of air compression, achieving peak efficiency in single-stage systems is challenging because it requires energy levels comparable to those of multi-stage systems. However, real-world factors such as energy loss in couplings, bearing friction, and cooling liquid viscosity often elevate energy use. By cleverly lowering the compression ratio at each stage, multi-stage compression mitigates these issues, resulting in a notably lower total energy demand compared to single-stage systems.
Introducing our cutting-edge two-stage screw air compressor, artfully crafted with a dual-stage rotary screw configuration. Each stage is equipped with a master and a supporting screw, where the master screw dynamically powers the supporting screw using an external power source. The first stage features a low-pressure screw setup, while the second stage is designed with a high-pressure screw assembly. Each screw is encased in a protective air film, skillfully compressing gas through three essential phases: suction, pressurization, and exhaust.
First Stage Compression: The initial phase involves the low-pressure screw group adeptly compressing the gas. As the gas is drawn into the compression chamber through a suction valve, it undergoes gradual compression and then smoothly transitions to the second stage, driven by the screw rotor's continuous rotation.
Second Stage Compression: Here, the gas enters a confined screw space, undergoing compression under intense temperatures and pressures. This phase culminates with the high-pressure gases being released from the system as the exhaust valve opens, thus completing the compression cycle.
The process begins with ambient air being precisely filtered before entering the initial compression stage, where it blends with a trace of lubricating oil. This mixture is compressed to an interstage pressure, traveling through a cooling conduit where it meets a substantial oil mist that significantly lowers its temperature. The cooled gas then advances to the second stage for further compression, finally exiting through the exhaust valve, thus completing the comprehensive compression sequence.
Harness the unparalleled cooling prowess of our water-cooled compressors, where the superior lubrication significantly extends the lifespan of components at risk of friction. With the circulation of cooling water, this system not only purifies internal parts but also efficiently dissipates heat from both the cylinder and compressed gas. This meticulous process remarkably reduces exhaust temperatures and power consumption, leading to substantial savings in operational costs. To maintain peak performance, regular monitoring and proactive management of potential scaling issues within the water cooling system are crucial.

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