Working Principle

Experience unparalleled efficiency with our advanced air compression process! While single-stage compression aims for optimal power usage, real-world scenarios often lead to increased power consumption due to factors like coupling power loss, bearing friction, and cooling liquid viscosity. By intelligently reducing the compression ratio at each stage, our multi-stage compression method significantly curtails these inefficiencies, ensuring superior performance with reduced total power requirements.

Discover the brilliance of our two-stage screw air compressor, a marvel of engineering featuring an innovative dual-stage rotary screw mechanism. Each stage comes with its own active and passive screws, where the active screw propels the passive screw using an external power device. The first stage employs a low-pressure rate screw group, while the second stage uses a high-pressure rate screw group. Encased in a sealing air film, these screws meticulously compress gas through three essential phases: suction, pressurization, and exhaust.

First Stage Compression: This process begins with the low-pressure rate screw group expertly compressing the gas. The gas enters the compression chamber via a suction valve, where it is gradually squeezed and then transferred to the second stage, driven by the high-speed rotation of the screw rotor.

Second Stage Compression: In this phase, the gas moves into a tighter screw space, encountering heightened compression at increased temperatures and pressures. The high-pressure gases are then efficiently expelled from the system as the exhaust valve opens, perfectly completing the compression cycle.

Our compression journey starts with natural air being meticulously filtered before entering the first compression stage. Here, it mixes with a precise amount of lubricating oil, and this mixture is compressed to interstage pressure. The compressed gas then traverses through a cooling channel, encountering a substantial amount of oil mist, which significantly lowers its temperature. This cooled gas then advances to the second stage for further compression, ultimately being expelled through the exhaust valve, thus masterfully completing the entire compression process.

Water-cooled compressors harness the unparalleled cooling prowess of water, delivering exceptional lubrication and extending the lifespan of high-friction components. As the cooling water circulates, it meticulously cleans internal parts and dissipates heat from both the cylinder and compressed gas. This highly efficient process dramatically reduces exhaust temperature and power consumption, translating into substantial operational cost savings. Consistent monitoring and tackling potential scaling issues within the water cooling system are critical to sustaining peak performance.

9) Minimized Internal Leakage:Employing a two-stage compression method reduces the compression ratio for each stage, thereby minimizing internal leakage from high-pressure to low-pressure ends and enhancing volumetric efficiency.

10) Noise Reduction:The two-stage compression design significantly lowers the compression ratio, resulting in a substantial reduction in operational noise, particularly during unloading.

11) Simplified Maintenance and Service:In addition to the screw air end, our two-stage compressor unit retains similar systems and structures to single-stage compressors, ensuring straightforward maintenance and user convenience.
