Advanced Working Principle
Delve into the fascinating world of air compression where achieving harmony between power demands and efficiency becomes an art. Ideally, single-stage power should equate to the combined might of multi-stage compression. Yet, real-world challenges such as coupling power losses, bearing friction, and cooling liquids add layers of complexity. By astutely lowering the compression ratio in each phase, these inefficiencies are cleverly minimized, paving the way for a multi-stage compression system that demands significantly less power than its single-stage counterpart. This innovative approach transforms the theoretical into the achievable, elevating efficiency to new heights.
Our state-of-the-art two-stage screw air compressor is a marvel of engineering innovation, featuring a pioneering dual-stage rotary screw system. At the heart of this system are two stages, each comprising an active and passive screw duo. The active screw, driven by an external force, orchestrates the movement of the passive screw. The initial stage showcases a low-pressure screw group, while the latter encompasses a high-pressure screw group. A sophisticated sealing air film envelops each screw, ensuring impeccable compression. As these screws rotate with precision, they expertly manage the gas through an orchestrated dance of suction, pressurization, and discharge, delivering performance that's both efficient and powerful.
First Stage Compression: The journey begins as gas is drawn into the low-pressure screw group, where the magic of compression unfolds. Through the suction valve, gas enters the compression chamber and is gradually compressed by the dynamic motion of high-speed screw rotors. This meticulous process channels the gas towards the secondary stage, setting the stage for enhanced efficiency and seamless transition.
Second Stage Compression: Entering a more confined arena, the gas encounters the intensity of the second stage. Within this restricted screw space, temperatures and pressures soar, culminating in a powerful crescendo. The cycle culminates with the opening of the exhaust valve, as high-pressure gas exits the system with remarkable efficiency, marking the triumphant conclusion of the compression journey.
As natural air enters our advanced compressor, it first undergoes purification via an air filter, ensuring only the purest air embarks on its compression journey. In the initial stage, this pristine air fuses with a touch of lubricating oil within the compression chamber, elevating its pressure to an intermediate level. As the journey continues, the compressed gas traverses a cooling channel, encountering a significant mist of oil that effectively lowers its temperature. With renewed vigor and reduced temperature, this gas advances into the second stage rotor. Here, it undergoes final compression, reaching 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: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.
