Working Principle
Our state-of-the-art permanent magnet frequency conversion air compressor is engineered to perfection. It employs a highly responsive pressure sensor that instantly detects the system's actual pressure and air consumption. Through the intricate orchestration of an electric and frequency converter, the motor speed is finely tuned without altering the air compressor motor's torque. This allows seamless regulation of system pressure, ensuring that compressed air output aligns precisely with demand. If the system's air consumption dips below the compressor's output, the inverter air compressor intelligently reduces its rotational speed, thereby minimizing air output. Conversely, it accelerates the motor speed to increase air output, maintaining a consistently stable system pressure.
Leveraging cutting-edge vector control technology, our units operate efficiently across a broad speed range while minimizing motor temperature rise. This ensures sufficient and appropriate torque to smoothly drive the air compressor. The motor current, composed of torque and other components, is meticulously managed by vector control technology. This distribution optimizes motor current values, allowing for maximum torque output even during voltage drops, without increasing current. It's a breakthrough in efficiency and performance.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Saving
With frequency conversion regulation, the actual power consumption of the frequency conversion compressor is proportionally reduced. This means energy is efficiently utilized for air compression, ensuring optimal performance and significant energy savings.
Cost Reducing
Experience substantial cost reductions with our permanent magnet frequency conversion technology. Energy costs are slashed by over 35%, and the overall life cycle cost of compressors is diminished by an average of 22%. The initial investment in the compressor is typically recovered within just 1 to 2 years, making it a financially sound choice.
Steady Pressure
Employing the precise PID (Proportional, Differential, Integral) method, our exclusive compressor is adept at maintaining system pressure stability. This ensures a reliable and consistent operation.
Life Extension
The frequency conversion start-up significantly reduces the impact on the power grid and machinery. This not only lessens wear and tear but also extends the service life of the compressor, ensuring long-term reliability and performance.
Top Quality
Our compressors are crafted with top-quality imported bearings and the latest rotor profile research and development. Featuring a large rotor with significant displacement, operating at low speed and low noise, these compressors enhance efficiency and production quality, setting a new benchmark for excellence.
