Advanced Working Principle
Explore the captivating realm of air compression, where balancing power demands with efficiency is elevated to an art form. Ideally, the power in a single stage should rival the combined strength of multi-stage compression. However, real-world challenges such as coupling power losses, bearing friction, and cooling liquids introduce complexities. Ingeniously reducing the compression ratio in each stage minimizes these inefficiencies, paving the way for a multi-stage compression system that is significantly more power-efficient than its single-stage equivalent. This groundbreaking approach transforms theory into reality, propelling efficiency to unprecedented levels.
Our cutting-edge two-stage screw air compressor is a testament to engineering brilliance, boasting a revolutionary dual-stage rotary screw system. Central to this system are two stages, each featuring an active and passive screw pair. The active screw, powered externally, orchestrates the synchronized movement of the passive screw. The first stage boasts a low-pressure screw group, while the second stage comprises a high-pressure screw group. Each screw is enveloped in a sophisticated sealing air film, ensuring flawless compression. As these screws rotate with precision, they expertly guide the gas through a masterful process of suction, pressurization, and discharge, delivering performance that is both incredibly efficient and remarkably powerful.
First Stage Compression: The journey of transformation begins as gas is drawn into the low-pressure screw group, where the magic of compression unfolds in a symphony of motion. Through the suction valve, gas enters the compression chamber, where the dynamic high-speed screw rotors gradually compress it. This meticulous process channels the gas towards the secondary stage, setting the stage for enhanced efficiency and a seamless transitional journey.
Second Stage Compression: In this phase, gas enters a more confined space, where it encounters the heightened intensity of the second stage. Within this restricted screw space, temperatures and pressures soar, reaching a powerful peak. The cycle triumphantly concludes as the exhaust valve opens, allowing the high-pressure gas to exit the system with remarkable efficiency, marking the grand finale of the compression journey.
As natural air enters our state-of-the-art compressor, it first undergoes purification via an advanced air filter, ensuring that only the purest air embarks on its compression journey. At the initial stage, this pristine air blends seamlessly with a touch of lubricating oil within the compression chamber, elevating its pressure to an intermediate level. As the journey progresses, the compressed gas travels through a cooling channel, encountering a fine mist of oil that effectively reduces its temperature. With renewed vigor and reduced temperature, this gas advances into the second stage rotor, where it undergoes final compression, reaching its ultimate exhaust pressure and exiting through the exhaust valve, completing a highly efficient and optimized compression cycle.
1) Superior Efficiency of PM Motor:Our state-of-the-art permanent magnet motor is engineered to deliver unparalleled performance. It operates with a broad spectrum of constant torque and weak magnetic fields, achieving an impressive 20-30% efficiency boost over standard motors. This guarantees exceptional efficiency at diverse frequencies, consistently providing top-tier performance.
2) Maintenance-Free Motor Design:Meticulously engineered with a focus on innovation, our permanent magnet motor features a bearing-free internal structure, eliminating costly bearing maintenance and replacements. Enjoy smooth operation with our user-friendly, maintenance-free motor design.
3) Advanced Integrated Frequency Converter: Our compressor is outfitted with China's premier frequency system, delivering precise and adaptable speed control. It adjusts seamlessly to real-time gas demands, optimizing energy usage and maximizing efficiency.
4) Elimination of Transmission Loss: Our groundbreaking integrated shaft design ensures the permanent magnet motor is directly connected to the compressor. This innovative, compact setup-free from couplings and extra transmission components-guarantees a flawless 100% transmission efficiency.
5) Variable Frequency and Soft Start Capabilities:Our advanced variable frequency and soft start features considerably reduce impacts on power grid infrastructures, protecting electrical systems from potential damage and increasing overall system durability.
6) Enhanced Energy Efficiency: Boasting a frequency conversion from 25% to 100% (as opposed to the typical 50% to 100%), our system saves over 30% more energy than fixed-speed compressors. It also outperforms standard variable frequency compressors by around 5%, offering even greater savings in fluctuating gas consumption conditions.
7) Unique Two-Stage Compression Air End:Our groundbreaking two-stage compression screw machine integrates both first and second-stage rotors within a single housing. The direct gear-drive ensures each rotor reaches optimal linear speed, significantly enhancing compression efficiency.
8) Innovative Internal Spray Curtain Cooling:Our high-efficiency internal spray curtain cooling technology significantly lowers compressed air temperatures via nearly isothermal compression, reducing pressure loss and boosting overall efficiency.
9) Minimized Internal Leakage:Leveraging our two-stage compression strategy, we markedly decrease the compression ratio per stage, minimizing internal leakage from high to low-pressure zones. This advancement results in superior volume efficiency.
10) Significant Noise Reduction:Our two-stage compression technique effectively reduces the compression ratio, dramatically lowering noise levels, particularly during unloading, fostering a quieter working environment.
11) Effortless Maintenance and Service:The two-stage compressor unit shares similar systems and structures with single-stage units, except for the screw air end, simplifying maintenance and ensuring ease of use for all operators.
