Working Principle

In the dynamic world of air compression, achieving an ideal balance where the power required for a single-stage pressure transmission equals that of multi-stage compression is a coveted goal. However, real-world scenarios often present challenges like coupling power loss, bearing friction, and the cooling impacts of liquid viscosity, all of which elevate the actual working power. To enhance efficiency, reducing the compression ratio at each stage becomes a pivotal strategy. This method ensures that the power needed across multiple stages is less than that required by a single-stage system, thus optimizing performance and minimizing energy wastage.

Introducing a groundbreaking two-stage screw air compressor, engineered with precision to deliver unparalleled efficiency. This advanced design features dual rotary screw compressors, with each comprising an active screw that drives a passive screw through external power transmission. The system's core comprises a low-pressure rate screw group at the first stage and a high-pressure rate variant at the second stage. Surrounding each screw is a sealing air film that enhances rotation efficiency. This sophisticated mechanism facilitates the seamless cycle of gas compression, from suction to pressurization to exhaust, ensuring superior performance.

First stage compression: The innovative two-stage screw air compressor begins its operation with a low-pressure rate screw group expertly compressing the gas. The gas enters the screw compression chamber through the suction valve, where the high-speed screw rotor rotates, gradually compressing the gas and directing it towards the second stage, setting the stage for efficient, seamless compression.

Second stage compression: As the compression cycle advances, the gas moves into a more confined space where it is subjected to increased temperature and pressure. Upon reaching the apex of compression, the exhaust valve activates, facilitating the smooth expulsion of high-pressure gas and maintaining optimal system efficiency.

Natural air, after purification through an air filter, embarks on its transformative journey into the first compression stage. Here, it integrates with a trace of lubricating oil within the compression chamber, where initial compression to interstage pressure occurs. The compressed gas then ventures through the cooling channel, interacting with a rich oil mist that significantly reduces its temperature. Subsequently, the cooled, compressed gas proceeds to the second-stage rotor, where it undergoes further compression, achieving the ultimate exhaust pressure. This meticulously orchestrated process culminates in the flawless release of compressed gas through the exhaust valve, epitomizing the efficiency and effectiveness of the entire compression journey.

2) Maintenance-Free Motor Innovation: Ingeniously crafted, the permanent magnet motor is devoid of internal bearings, dramatically cutting down on maintenance expenses related to motor bearing care and replacements.

3) Integrated Frequency Converter Excellence: Equipped with China's premier frequency system, this feature offers a broad speed regulation range with precise control. It tailors to actual gas needs, enhancing efficient frequency modulation and displaying exceptional energy-saving prowess of the compressor.

4) Flawless Transmission Efficiency: The motor and compressor are seamlessly linked through an integrated shaft structure, achieving a sleek design with perfect 100% transmission efficiency, free from couplings or extra transmission elements.

5) Variable Frequency & Soft Start Enhancement: Ingeniously engineered, this feature minimizes impact on power grid equipment, effectively shielding electrical systems from harm while ensuring smooth operation.

6) Superior Energy Efficiency: Boasting a frequency conversion range from 25% to 100%, it delivers over 30% energy savings compared to fixed-speed compressors. It provides an extra 5% savings over typical variable frequency models, with even more pronounced savings during significant gas consumption fluctuations.

7) Innovative Two-Stage Compression Air End: This inventive two-stage compression screw machine combines the first and second-stage rotors within a single casing, each gear-driven for optimal linear speed and peak compression efficiency.

8) Cutting-Edge Internal Spray Curtain Cooling: This revolutionary cooling method excels in energy efficiency and provides superior cooling, significantly lowering compressed air temperatures. It achieves near-isothermal compression, reducing pressure loss, compression ratio, and boosting efficiency.

9) Reduced Internal Leakage: Employing two-stage compression lowers the compression ratio per stage, minimizing internal leakage from high to low pressure ends, thereby enhancing volume efficiency.

10) Exceptional Noise Reduction: Two-stage compression notably decreases the compression ratio, leading to a substantial reduction in noise levels, particularly during unloading.

11) Effortless Maintenance and Service: The two-stage compressor unit retains the same system structures as single-stage compression, aside from the screw air end, simplifying maintenance procedures and user operations.
