Working Principle

In the grand realm of air compression technology, the ultimate vision unfolds where the energy required for a single-stage pressure transmission equates to the sum power of a multi-stage compression. Yet, in the real world, elements such as coupling power loss, bearing friction, and cooling effects due to liquid viscosity challenge this ideal by boosting actual power consumption. To tackle this, reducing the compression ratio at every stage emerges as a strategic solution. This approach guarantees that the total energy demand for multi-stage compression remains beneath that of a single-stage system, thereby optimizing performance and curtailing energy wastage.

Unveiling a cutting-edge two-stage screw air compressor with an innovative design, boasting dual rotary screw compressors, each featuring both an active and a passive screw. In this sophisticated architecture, the active screw, powered by an external transmission system, drives the passive screw. This dynamic configuration starts with a low-pressure rate screw group in the first stage, while the second stage amplifies the process with a high-pressure rate variant. Encased by a sealing air film, each screw enhances the rotational process, enabling gas compression through a seamless cycle of suction, pressurization, and exhaust, thus guaranteeing top-tier efficiency and exceptional performance.

First stage compression: At this crucial onset, the two-stage screw air compressor utilizes a low-pressure rate screw group to adeptly compress the gas. As the gas traverses into the screw compression chamber via the suction valve, the rapid rotation of the high-speed screw rotor compresses and propels the gas to the second stage, establishing a robust foundation for effective compression.

Second stage compression: Advancing to the second stage, the gas encounters a more confined screw space, where it is subjected to increased temperature and pressure. As compression peaks, the exhaust valve activates, effortlessly discharging high-pressure gas and maintaining optimal system efficiency.

Embarking on its journey, natural air filtered for purity enters the first compression stage, blending with a trace of lubricating oil in the compression chamber. This mixture undergoes compression to interstage pressure. The compressed gas then traverses the cooling channel, interacting with a rich oil mist to substantially reduce its temperature. The cooled, compressed gas proceeds to the second-stage rotor for another round of compression, reaching the ultimate exhaust pressure. Culminating its journey, the gas exits seamlessly through the exhaust valve, completing a flawlessly choreographed compression process.

1) Unrivaled Efficiency of the PM Motor: Prepare to be amazed by the exceptional performance of the permanent magnet motor, which offers a vast constant torque and a robust weak magnetic range. This powerhouse outshines traditional motors, delivering an astonishing 20-30% increase in efficiency. Even beyond its rated frequency, the motor maintains an exceedingly impressive efficiency level.

2) Effortless Motor Maintenance: Experience groundbreaking innovation with the permanent magnet motor's architecture. By eliminating internal bearings, maintenance costs related to motor bearing upkeep and replacement are dramatically reduced, promising a hassle-free experience.

3) Effortlessly Integrated Frequency Converter: Leveraging China's foremost frequency system, this integrated converter offers a broad and flexible speed regulation range, combined with precise control. It aligns seamlessly with real-time gas demands, making frequency modulation incredibly efficient and enhancing the compressor's remarkable energy-saving capabilities.

4) Perfect Transmission Efficiency: Revel in the brilliance of the embedded integrative shaft structure, which directly couples the permanent magnet motor and compressor. This design ensures a compact form and delivers flawless 100% transmission efficiency, eliminating the need for any coupling or additional transmission components.

5) Optimized Variable Frequency and Soft Start: This sophisticated feature expertly minimizes impact on power grid equipment, offering effective protection to your electrical systems and safeguarding against potential damage.

6) Superior Energy Efficiency: Marvel at the incredible energy efficiency with a frequency conversion range stretching from 25% to 100%, as opposed to the ordinary 50% to 100%. This results in over 30% energy savings compared to fixed-speed compressors. Furthermore, it provides approximately 5% additional savings compared to standard variable frequency models. Greater fluctuations in gas consumption lead to even more pronounced savings.

7) Groundbreaking Two-Stage Compression Air End: Ingeniously crafted, the two-stage compression screw machine integrates the first and second-stage rotors within a single casing. Each rotor is driven directly by gears, achieving optimal linear speed and maximizing compression efficiency to new heights.

8) Cutting-Edge Internal Spray Curtain Cooling: Celebrated for its outstanding energy efficiency, this advanced cooling technique ensures exceptional performance. It substantially lowers compressed air temperature, approaching near-isothermal compression, which minimizes pressure loss and compression ratio, thereby significantly boosting overall efficiency.

9) Reduced Internal Leakage: The use of two-stage compression reduces the compression ratio per stage, effectively lessening internal leakage from high to low-pressure zones, thereby enhancing volume efficiency to a remarkable degree.

10) Outstanding Noise Reduction: The innovative two-stage compression technique notably diminishes the compression ratio, leading to a drastic reduction in noise levels, particularly during unloading, ensuring a quieter operation.

11) Streamlined Maintenance and Service: Designed for ease of use, the two-stage compressor unit retains the same system structures as single-stage compression models, aside from the advanced screw air end. This ensures straightforward maintenance tasks and user-friendly operation, making it a breeze to manage.
