Working Principle
In the realm of air compression, achieving optimal efficiency with single-stage compression ideally requires power consumption equivalent to that of multi-stage compression. However, real-world operations often face inefficiencies due to coupling power loss, friction in bearings, and the viscosity of cooling liquids, all contributing to increased power demands. Multi-stage compression resolves these issues by reducing the compression ratio at each stage, thereby significantly diminishing inefficiencies and resulting in a substantially reduced total power requirement when compared to single-stage compression.
Introducing our revolutionary two-stage screw air compressor, which boasts a sophisticated dual-stage rotary screw mechanism. Each stage is ingeniously equipped with both an active and a passive screw. The active screw energizes the passive screw via an external power source. The first stage is characterized by a low-pressure rate screw group, while the second stage is defined by a high-pressure rate screw group. Surrounding each screw is an innovative sealing air film, facilitating the compression of gas through three distinct stages: suction, pressurization, and exhaust.
First Stage Compression: The compression journey begins with the low-pressure rate screw group skillfully compressing the gas. As the gas enters the compression chamber through a suction valve, it undergoes progressive compression, propelled by the vigorous rotation of the screw rotor, and is then transferred to the second stage.
Second Stage Compression: During this crucial phase, the gas is funneled into a narrower screw space, where it undergoes compression under heightened temperatures and pressures. As the exhaust valve opens, the high-pressure gases are efficiently expelled from the system, thus completing the compression cycle.
The process initiates with ambient air being precisely filtered before it enters the first compression stage. Here, it is amalgamated with a small amount of lubricating oil. This mixture is compressed to interstage pressure and travels through a cooling channel, encountering a substantial oil mist that significantly reduces its temperature. The cooled gas then progresses to the second stage for further compression, eventually being released through the exhaust valve, thus completing the entire compression sequence.
Harness the extraordinary cooling prowess of our water-cooled compressors, unlocking optimal lubrication and extending the lifespan of those crucial, high-friction components. As the cooling water flows seamlessly, it purges internal parts, dissipating the heat from the cylinder and compressed gas with absolute precision. This state-of-the-art process slashes exhaust temperatures and trims down power consumption, translating into significant operational cost savings. Consistent monitoring and prompt attention to potential scaling within the water cooling system are essential to sustain peak performance.

It drastically reduces the temperature of compressed air, closely mirroring isothermal compression, and minimizes pressure loss between stages, thereby maximizing compression efficiency.
9) Significantly Minimized Internal Leakage:Our two-stage compression approach reduces the compression ratio for each stage, thereby minimizing internal leakage from the high-pressure to low-pressure ends, enhancing volumetric efficiency.
10) Remarkable Noise Reduction:The innovative two-stage compression design significantly lowers the compression ratio, leading to a substantial decrease in operational noise, especially noticeable during unloading.
11) Streamlined Maintenance and Service:Aside from the advanced screw air end, our two-stage compressor unit maintains systems and structures akin to single-stage compressors, ensuring straightforward maintenance and user-friendly operation.
