Advanced Working Principle
Dive into the intricate art of air compression, where balancing power and efficiency becomes a masterpiece. Ideally, the power of single-stage compression should match the might of its multi-stage counterparts. However, real-world challenges like power loss, friction, and cooling complexities often complicate this balance. By strategically reducing compression ratios in each stage, these inefficiencies are significantly minimized, creating a multi-stage compression system that is remarkably more power-efficient than single-stage alternatives. This innovative approach transforms theoretical potential into tangible achievements, unlocking new heights of efficiency.
Our cutting-edge two-stage screw air compressor stands as a beacon of engineering brilliance, featuring an innovative dual-stage rotary screw system. This system's core comprises two distinct stages, each with an active and passive screw pair. The active screw propels the passive screw through external force, creating a synchronized operation. The initial stage features a low-pressure screw group, transitioning to a high-pressure group in the latter stage. Encased within a refined sealing air film, these screws perform with impeccable precision, orchestrating gas management through a synchronized dance of suction, pressurization, and discharge, delivering unmatched efficiency and power.
First Stage Compression: Embark on the journey of compression as gas is drawn into the low-pressure screw group, where the magic of compression unfurls. The gas enters through the suction valve into the compression chamber, where it's gradually compressed by high-speed screw rotors. This meticulous process efficiently channels the gas toward the secondary stage, enhancing efficiency and ensuring a seamless transition in the compression journey.
Second Stage Compression: In this intensified arena, the gas faces the dynamic force of the second stage. Here, within a more confined screw space, temperatures and pressures escalate, building to an impressive peak. The cycle culminates triumphantly as high-pressure gas is released through the exhaust valve, marking the powerful conclusion of this efficient compression journey.
As ambient air enters our state-of-the-art compressor, it first passes through an air filter, ensuring only the purest air begins its compression journey. At the outset, this pristine air combines with a hint of lubricating oil within the compression chamber, increasing its pressure to an intermediate level. As the journey progresses, the compressed gas navigates a cooling channel, encountering a cooling mist of oil that significantly reduces temperature. With renewed energy and reduced heat, this gas proceeds to the second stage rotor for final compression, reaching ultimate exhaust pressure, and exits through the exhaust valve, completing a highly efficient and optimized compression cycle.
1) Superior Efficiency of PM Motor:Our cutting-edge permanent magnet motor is meticulously crafted to deliver outstanding performance. Designed to operate with an expansive range of constant torque and weak magnetic fields, it achieves a remarkable 20-30% higher efficiency than conventional motors. This ensures top-tier performance across a spectrum of frequencies, consistently delivering unparalleled efficiency.
2) Maintenance-Free Motor Design:Ingeniously crafted with innovation as its essence, our permanent magnet motor features an internal structure free of bearings, thus eliminating the costly and time-consuming process of bearing maintenance and replacements. Enjoy smooth and uninterrupted operation with our effortless motor design.
3) Advanced Integrated Frequency Converter: Our compressor is equipped with China's leading frequency system, delivering precision in speed modulation. It seamlessly adapts to real-time gas requirements, optimizing energy usage and maximizing efficiency for superior performance.
4) Elimination of Transmission Loss: Our revolutionary integrated shaft design connects the permanent magnet motor directly to the compressor. This modern compact structure, devoid of couplings and extra transmission components, guarantees an impeccable 100% transmission efficiency.
5) Variable Frequency and Soft Start Capabilities:Our advanced variable frequency and soft start features significantly reduce the impact on power grid systems. They protect electrical components from potential damage, enhancing system robustness and longevity.
6) Enhanced Energy Efficiency: With a frequency conversion range from 25% to 100% (as opposed to the standard 50% to 100%), our system surpasses standard fixed-speed compressors by over 30% in energy conservation. It also outperforms typical variable frequency compressors by about 5%, offering heightened savings even amidst fluctuating gas demands.
7) Unique Two-Stage Compression Air End:Our groundbreaking two-stage compression screw mechanism houses both first and second-stage rotors in a single casing. The direct gear-drive ensures that each rotor reaches optimal linear speeds, greatly enhancing compression efficiency.
8) Innovative Internal Spray Curtain Cooling:Our high-performance internal spray curtain cooling technique significantly reduces compressed air temperatures via nearly isothermal compression, diminishing pressure loss and boosting overall efficiency.
9) Minimized Internal Leakage:Thanks to our two-stage compression strategy, we substantially lower the compression ratio for each stage, thereby minimizing internal leakage from high to low-pressure zones. This advancement results in superior volume efficiency.
10) Significant Noise Reduction:Our two-stage compression methodology adeptly reduces the compression ratio, significantly diminishing operational noise, particularly during unloading phases, to furnish a more serene working environment.
11) Effortless Maintenance and Service:The two-stage compressor unit mirrors the systems and structures of single-stage units, except for the screw air end, simplifying maintenance and ensuring user-friendly operation for all operators.
