Advanced Working Principle
Embark on a journey into the captivating realm of air compression, where aligning power requirements with efficiency elevates to an art form. The ideal scenario envisions single-stage power equaling the collective force of multi-stage compression. Yet, real-world complexities like coupling power losses, bearing friction, and cooling liquid intricacies add depth to this process. By intelligently moderating the compression ratio at each stage, these inefficiencies are skillfully reduced, leading to a multi-stage compression system that requires substantially less power than a single-stage equivalent. This groundbreaking strategy transforms theoretical aspirations into achievable realities, setting new benchmarks in efficiency.
Our cutting-edge two-stage screw air compressor embodies engineering excellence, featuring an innovative dual-stage rotary screw mechanism. Central to this system are two stages, each with an active and passive screw pair. The active screw, powered externally, guides the passive screw's movement. Initially, a low-pressure screw group operates, followed by a high-pressure screw group. A refined air film envelops each screw, ensuring pristine compression. As these screws rotate in perfect harmony, they manage the gas through an intricate choreography of suction, pressurization, and discharge, delivering performance that is both formidable and efficient.
First Stage Compression: The journey begins as gas enters the low-pressure screw group, where the wonders of compression commence. Through the suction valve, gas navigates into the compression chamber, undergoing gradual compression by the high-speed screw rotors' dynamic motion. This meticulous process directs the gas towards the second stage, setting the stage for heightened efficiency and a flawless transition.
Second Stage Compression: Entering a more confined space, the gas faces the second stage's intensity. Within this compact screw environment, temperatures and pressures escalate, reaching a powerful apex. The cycle concludes as the exhaust valve opens, allowing high-pressure gas to exit the system with outstanding efficiency, marking the victorious end of its compression journey.
As ambient air enters our advanced compressor, it first undergoes purification through an air filter, allowing only the purest air to proceed on its compression path. In the initial stage, this purified air combines with lubricating oil within the compression chamber, raising its pressure to an intermediate level. As the journey progresses, the compressed gas flows through a cooling channel, encountering an oil mist that significantly reduces its temperature. Revitalized and cooler, this gas moves into the second stage rotor, where it undergoes final compression, reaching its peak exhaust pressure, and exits through the exhaust valve, completing a proficient and optimized compression cycle.
1) Superior Efficiency of PM Motor:Our cutting-edge permanent magnet motor is meticulously crafted to deliver outstanding performance. Offering an expansive range of constant torque and weak magnetic fields, it achieves an astonishing 20-30% higher efficiency compared to conventional motors. This ensures supreme efficiency across diverse frequencies, consistently delivering top-notch performance.
2) Maintenance-Free Motor Design:Ingeniously designed with innovation at its core, our permanent magnet motor boasts a bearing-free internal structure, eliminating the need for expensive bearing upkeep and replacements. Experience seamless operation with our easy-to-maintain motor design.
3) Advanced Integrated Frequency Converter: Our compressor is equipped with China's leading frequency system, providing precise and wide-ranging speed regulation. It seamlessly adapts to real-time gas requirements, optimizing energy use while enhancing efficiency to the fullest.
4) Elimination of Transmission Loss: With our pioneering integrated shaft design, the permanent magnet motor connects directly to the compressor. This modern, compact structure-void of couplings and additional transmission elements-ensures absolute 100% transmission efficiency.
5) Variable Frequency and Soft Start Capabilities:Our sophisticated variable frequency and soft start functions significantly alleviate impacts on power grid systems, safeguarding electrical components from potential harm and augmenting system resilience.
6) Enhanced Energy Efficiency: Featuring a frequency conversion range from 25% to 100% (compared to the usual 50% to 100%), our system provides more than 30% energy savings compared to fixed-speed compressors. It also surpasses standard variable frequency compressors by approximately 5%, delivering even greater savings under fluctuating gas consumption scenarios.
7) Unique Two-Stage Compression Air End:Our revolutionary two-stage compression screw machine incorporates both first and second-stage rotors within a single casing. Direct gear-drive ensures each rotor achieves peak linear speed, significantly boosting compression efficiency.
8) Innovative Internal Spray Curtain Cooling:Our high-performance internal spray curtain cooling technique dramatically lowers compressed air temperatures through nearly isothermal compression, reducing pressure loss and enhancing overall efficiency.
9) Minimized Internal Leakage:Through our two-stage compression approach, we significantly decrease the compression ratio for each stage, minimizing internal leakage from high to low-pressure ends. This enhancement results in improved volume efficiency.
10) Significant Noise Reduction:Our two-stage compression methodology effectively reduces the compression ratio, substantially lowering operational noise, especially during unloading phases, creating a quieter working atmosphere.
11) Effortless Maintenance and Service:The two-stage compressor unit shares comparable systems and structures with single-stage units, apart from the screw air end, simplifying maintenance and ensuring easy usability for all operators.
