Product Structure

 

Working Principle

The permanent magnet frequency conversion air compressor is a marvel of engineering that utilizes an ultra-sensitive pressure sensor to detect real-time system pressure and air consumption. Through the harmonious integration of electrical and frequency converter controls, it skillfully adjusts motor speed without changing the motor's torque. This intelligent calibration ensures that system pressure remains consistent, providing precisely the amount of compressed air required. When air consumption decreases, and the compressor's output surpasses demand, the innovative inverter gracefully reduces motor speed, thereby decreasing compressed air output. Conversely, by smoothly accelerating the motor, the system increases compressed air supply, maintaining pressure equilibrium and guaranteeing a seamless balance throughout the system.

By leveraging cutting-edge vector control technology, these compressors operate effortlessly across an extensive range of speeds, ensuring minimal motor temperature rise. This exceptional synergy delivers the ideal torque necessary for seamless air compressor operation. By partitioning motor current into torque and auxiliary components, vector control ensures optimal current distribution, providing maximum torque output even during voltage fluctuations at the motor end, while maintaining steady current levels. This intelligent adaptability ensures the motor operates at peak efficiency, elevating performance to new heights.


Advantages of Permanent Magnet Variable Frequency Screw Air Compressor

High Efficiency and Energy Saving
The frequency conversion regulation perfectly aligns power consumption with operational requirements, optimizing energy use in air compression. Each watt is strategically utilized, making the operations exceptionally efficient and inherently eco-friendly.

Cost Reducing
Utilizing permanent magnet frequency conversion technology, energy costs can be lowered by over 35%, while the compressor's life cycle costs are reduced by an average of 22%. This initial investment typically pays for itself within 1 to 2 years, making it a wise and cost-effective choice.

Steady Pressure
The PID (Proportional, Integral, Derivative) control method expertly fine-tunes the compressor, ensuring consistent system pressure for optimal precision and operational stability.

Life Extension
Frequency conversion start-up minimizes stress on the power grid and machinery, effectively prolonging equipment service life by reducing wear and tear, thus ensuring long-term reliability.

Top Quality
By integrating top-tier imported bearings and pioneering rotor profile advancements, these compressors boast large rotors with significant displacement operating at low speeds. This results in reduced noise, enhanced efficiency, and outstanding production quality, epitomizing a benchmark of excellence.
