Advanced Working Principle
Unlock the captivating realm of air compression, where artful synergy between power and efficiency reigns supreme. Ideally, the strength of single-stage power should match the collective force of multi-stage compression. However, real-world obstacles like coupling power losses, bearing friction, and cooling liquid intricacies add to the challenge. By intelligently reducing the compression ratio in each stage, these challenges are skillfully overcome, creating a multi-stage compression system that requires substantially less power than its single-stage counterpart. This progressive strategy transforms theoretical concepts into practical achievements, pushing efficiency to unprecedented levels.
Our cutting-edge two-stage screw air compressor embodies engineering brilliance, boasting an innovative dual-stage rotary screw system. Central to this system are two distinct stages, each featuring a dynamic duo of active and passive screws. The active screw, powered by external forces, masterfully orchestrates the motion of its passive counterpart. The initial phase is characterized by a low-pressure screw group, while the succeeding stage houses a high-pressure screw group. A sophisticated sealing air film enshrouds each screw, ensuring flawless compression. As these screws rotate with unparalleled precision, they skillfully manage gas through a choreographed sequence of suction, pressurization, and discharge, delivering performance that is as efficient as it is powerful.
First Stage Compression: The journey initiates as gas is gently pulled into the low-pressure screw group, where the wonders of compression unfold. Through the suction valve, the gas enters the compression chamber, undergoing gradual compression by the swift motion of high-speed screw rotors. This precise process guides the gas towards the subsequent stage, paving the way for enhanced efficiency and seamless progression.
Second Stage Compression: As the gas enters a more constricted environment, it encounters the formidable intensity of the second stage. Within this compact screw space, temperatures and pressures escalate, leading to a powerful climax. The cycle concludes with the exhaust valve opening, as high-pressure gas exits the system with remarkable efficiency, marking the triumphant finale of the compression journey.
As ambient air is drawn into our state-of-the-art compressor, it first experiences purification via an air filter, ensuring only the purest air embarks on its compression voyage. In the initial stage, this pristine air merges with a hint of lubricating oil within the compression chamber, elevating its pressure to an intermediate level. As the journey progresses, the compressed gas navigates a cooling channel, encountering a substantial mist of oil that effectively reduces its temperature. Refreshed and cooler, this gas progresses into the second stage rotor, where it undergoes final compression, achieving peak exhaust pressure, and is expelled 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 a marvel of craftsmanship, designed to offer exceptional performance. With its broad range of constant torque and weak magnetic fields, it delivers a remarkable 20-30% increase in efficiency over traditional motors. This guarantees unparalleled efficiency across various frequencies, ensuring consistently high-caliber performance in all operations.
2) Maintenance-Free Motor Design:Brilliantly conceived with innovation at its heart, our permanent magnet motor features a unique bearing-free internal configuration, completely eradicating the need for costly bearing maintenance and replacements. Enjoy uninterrupted and smooth operation with our maintenance-free motor design.
3) Advanced Integrated Frequency Converter: Our compressor is outfitted with China's premier frequency system, delivering precise and extensive speed regulation. It intuitively adjusts to real-time gas demands, maximizing energy utilization while thoroughly enhancing efficiency.
4) Elimination of Transmission Loss: Thanks to our innovative integrated shaft design, the permanent magnet motor is directly coupled to the compressor. This sleek, compact setup, free from couplings and extra transmission components, guarantees faultless 100% transmission efficiency.
5) Variable Frequency and Soft Start Capabilities:Our advanced variable frequency and soft start features markedly reduce impacts on power grid systems, protecting electrical components from potential damage and bolstering system durability.
6) Enhanced Energy Efficiency: With a frequency conversion range spanning 25% to 100% (outshining the conventional 50% to 100%), our system achieves over 30% energy savings compared to fixed-speed compressors. It also exceeds standard variable frequency compressors by about 5%, offering even greater savings under variable 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 enables each rotor to reach optimal linear speed, dramatically elevating compression efficiency.
8) Innovative Internal Spray Curtain Cooling:Our high-efficiency internal spray curtain cooling method significantly reduces compressed air temperatures through near-isothermal compression, diminishing pressure loss and boosting overall efficiency.
9) Minimized Internal Leakage:Utilizing our two-stage compression method, we notably reduce the compression ratio for each stage, minimizing internal leakage from high to low-pressure ends. This advancement results in heightened volume efficiency.
10) Significant Noise Reduction:Our two-stage compression technique effectively decreases the compression ratio, considerably reducing operational noise, especially during unloading phases, fostering a quieter working environment.
11) Effortless Maintenance and Service:The two-stage compressor unit retains similar systems and structures to single-stage units, aside from the screw air end, simplifying maintenance and ensuring effortless usability for all operators.
