Dynamic Working Principle
In the air compression journey, achieving peak efficiency in single-stage compression demands that the power used should be equal to the collective effort of multi-stage compression. However, real-world scenarios often encounter inefficiencies such as coupling power loss, bearing friction, and cooling liquid viscosity that lead to elevated power usage. Multi-stage compression, by lowering the compression ratio at each stage, can significantly curb these inefficiencies, resulting in a notably lower total power requirement compared to single-stage compression.
Step into the future with our revolutionary two-stage screw air compressor, a marvel of engineering featuring a dual-stage rotary screw mechanism. Each stage boasts both an active and a passive screw, propelled by an external power source. The first stage is ingeniously crafted with a low-pressure rate screw group, while the second stage is equipped with a high-pressure rate screw group. Every screw is enveloped by a sealing air film, ingeniously designed to compress the gas through three meticulously orchestrated phases: suction, pressurization, and exhaust.
First Stage Compression: Embark on the compression journey as the low-pressure rate screw group efficiently compresses the gas. Gas gracefully enters the compression chamber through a suction valve, progressively compressed and dynamically transferred to the second stage, driven by the vigorous rotation of the screw rotor.
Second Stage Compression: In this critical phase, the gas is expertly transitioned into a narrower screw space, where it undergoes compression at elevated temperatures and pressures. As the exhaust valve opens, the high-pressure gases are liberated from the system, elegantly concluding the compression cycle.
The process commences with natural air being meticulously filtered before entering the initial compression stage, where it harmonizes with a slight amount of lubricating oil. This fusion is then compressed to interstage pressure, navigating through a cooling channel where it encounters a substantial amount of oil mist, dramatically reducing its temperature. The cooled gas subsequently advances to the second stage for enhanced compression, ultimately being expelled through the exhaust valve, thus completing the comprehensive compression sequence with precision and efficiency.
Water-cooled compressors are meticulously designed to harness the remarkable cooling prowess of water, resulting in outstanding lubrication and an extended lifespan for components prone to friction. As the cooling water circulates, it cleans internal parts efficiently and dissipates heat from both the cylinder and the compressed gas. This highly efficient process significantly reduces exhaust temperatures and power consumption, yielding substantial savings in operational costs. Regular monitoring and prompt attention to potential scaling issues within the water cooling system are imperative to sustain optimal performance.

Even when operating at non-rated frequencies, the motor consistently maintains high efficiency, ensuring superior performance at all times.
2) Maintenance-Free Motor:Ingeniously designed without internal bearings, our permanent magnet motor eliminates the need for costly and time-consuming maintenance as well as bearing replacements, providing a smooth and trouble-free experience.
3) Integrated Frequency Converter:Equipped with China's top-tier frequency system, this unit boasts a vast speed regulation range and unparalleled precision. It seamlessly adjusts to real-time gas demand, delivering exceptional energy-saving benefits for the air compressor.
4) Zero Transmission Loss:By incorporating an integrated shaft structure that directly connects the permanent magnet motor and compressor, this innovative design eradicates the need for couplings and other transmission components, achieving a perfect transmission efficiency of 100%.
5) Variable Frequency and Soft Start:Our motor is engineered for variable frequency start and soft start, which dramatically curtails impact on power grid equipment and provides robust protection against potential damage to electrical components.
6) Enhanced Energy Efficiency:With a frequency conversion range of 25% to 100%, surpassing the standard range of 50% to 100%, our system offers over 30% energy savings compared to fixed speed compressors. It also achieves approximately 5% more energy savings than standard variable frequency compressors, with even greater savings during significant fluctuations in system gas consumption.
7) Unique Two-Stage Compression Air End:Our two-stage compression screw machine is equipped with a unique air end, integrating first-stage and second-stage compression rotors within a single casing. These rotors operate with gears to achieve the ideal linear speed for each stage, markedly boosting compression efficiency.
8) Innovative Internal Spray Curtain Cooling:Our groundbreaking internal spray curtain cooling technology delivers extraordinary cooling capabilities. It significantly reduces the temperature of compressed air, closely approximating isothermal compression, and decreases pressure loss between stages, thereby maximizing compression efficiency.
9) Minimized Internal Leakage:Employing a two-stage compression method lowers the compression ratio for each stage, effectively minimizing internal leakage from high-pressure to low-pressure ends and enhancing volumetric efficiency.
10) Noise Reduction:The two-stage compression design substantially decreases the compression ratio, leading to a notable reduction in operational noise, particularly during unloading.
11) Simplified Maintenance and Service:Apart from the screw air end, our two-stage compressor unit retains the same systems and structures as single-stage compressors, ensuring easy maintenance and user-friendly operation.
