Advanced Working Principle
Immerse yourself in the captivating realm of air compression, where balancing power and efficiency becomes a refined art. In an ideal setup, single-stage power should match the collective strength of multi-stage compression. However, real-world hurdles like power losses during coupling, bearing friction, and cooling liquid complexities add layers of challenge. By adeptly reducing compression ratios at each phase, these inefficiencies are cleverly mitigated, leading to a multi-stage system that requires significantly less power than a single-stage one. This avant-garde approach turns theoretical possibilities into reality, elevating efficiency to remarkable new levels.
Our cutting-edge two-stage screw air compressor stands as a monument of engineering excellence, featuring an innovative dual-stage rotary screw system. This system's core consists of two stages, each housing an active and passive screw pair. The active screw, driven externally, orchestrates the motion of the passive counterpart. The first stage features a low-pressure screw group, followed by a high-pressure screw group. An advanced sealing air film envelops each screw, ensuring flawless compression. As these screws rotate with precision, they adeptly handle the gas through a synchronized ballet of suction, pressurization, and discharge, delivering performance that is both efficient and powerful.
First Stage Compression: The journey commences as gas is drawn into the low-pressure screw group, where the intricate magic of compression begins. Gas enters the compression chamber through the suction valve and is gradually compressed by the dynamic motion of high-speed screw rotors. This meticulous process directs the gas towards the secondary stage, paving the way for enhanced efficiency and a seamless transition.
Second Stage Compression: Entering a confined realm, the gas confronts the intensified conditions of the second stage. Within this restricted screw space, temperatures and pressures surge, culminating in a powerful climax. The cycle concludes with the exhaust valve opening as high-pressure gas exits the system with remarkable efficiency, marking the grand finale of the compression journey.
As ambient air enters our advanced compressor, it undergoes initial purification via an air filter, ensuring that only the purest air embarks on its compression journey. In the first stage, this pristine air merges with a touch of lubricating oil within the compression chamber, boosting its pressure to an intermediate level. As the journey progresses, the compressed gas traverses a cooling pathway, encountering a significant mist of oil that effectively lowers its temperature. Revitalized and with reduced temperature, the gas advances into the second stage rotor, undergoing final compression to reach its ultimate exhaust pressure and is expelled through the exhaust valve, completing a highly efficient and optimized compression cycle.
1) Superior Efficiency of PM Motor:Experience the pinnacle of performance with our state-of-the-art permanent magnet motor. Expertly engineered, this motor delivers unparalleled performance with a vast spectrum of constant torque and weak magnetic field capabilities. Achieving a remarkable 20-30% efficiency improvement over standard motors, it excels across a variety of frequencies, ensuring exceptional efficiency and delivering consistently high performance.
2) Maintenance-Free Motor Design:Our ingeniously innovative permanent magnet motor design, crafted with an emphasis on innovation, features a bearing-free internal structure. This eliminates the costly need for bearing maintenance and replacements, guaranteeing smooth and uninterrupted operation with a design that is effortless to maintain.
3) Advanced Integrated Frequency Converter: Equipped with China's premier frequency system, our compressor offers precise and extensive speed regulation. It automatically adjusts to real-time gas demands, optimizing energy consumption while maximizing efficiency, ensuring peak performance at all times.
4) Elimination of Transmission Loss: Thanks to our revolutionary integrated shaft design, the permanent magnet motor is directly coupled to the compressor. This sleek and modern configuration, devoid of couplings and extra transmission elements, guarantees flawless 100% transmission efficiency, making it a standout in efficiency.
5) Variable Frequency and Soft Start Capabilities:Our advanced variable frequency and soft start functionalities dramatically reduce impacts on the power grid, protecting electrical components from potential damage and significantly boosting system resilience, ensuring a robust and reliable performance.
6) Enhanced Energy Efficiency: Our system, with a frequency conversion range from 25% to 100%, far exceeds the usual 50% to 100% range. This feature yields over 30% energy savings compared to fixed-speed compressors and surpasses the energy efficiency of standard variable frequency compressors by about 5%, offering even more savings in scenarios with fluctuating gas consumption.
7) Unique Two-Stage Compression Air End:Explore the game-changing efficiency of our unique two-stage compression screw machine, which houses both first and second-stage rotors in a single casing. The direct gear-drive ensures each rotor reaches optimal linear speed, substantially enhancing compression efficiency for superior performance.
8) Innovative Internal Spray Curtain Cooling:Our trailblazing internal spray curtain cooling method significantly reduces compressed air temperatures through near-isothermal compression, cutting down pressure loss and boosting overall efficiency, ensuring your operations run cooler and more efficiently.
9) Minimized Internal Leakage:Our pioneering two-stage compression significantly lowers the compression ratio for each stage, reducing internal leakage from high to low-pressure ends. This improvement enhances volume efficiency, ensuring optimal performance and reduced energy wastage.
10) Significant Noise Reduction:Our innovative two-stage compression approach effectively reduces the compression ratio, leading to a marked decrease in operational noise, especially during unloading phases. This creates a quieter, more pleasant working environment, enhancing workplace comfort.
11) Effortless Maintenance and Service:Designed with user-friendliness in mind, the two-stage compressor unit shares similar systems and structures with single-stage units, except for the screw air end. This design simplifies maintenance procedures, ensuring that operators can easily and efficiently service the unit as needed, maximizing uptime and operational convenience.
