Product Structure

 

Working Principle

The permanent magnet frequency conversion air compressor, a marvel of engineering, utilizes an ultra-responsive pressure sensor that flawlessly detects the system's real-time pressure and air demand. By harmoniously integrating electric and frequency converter controls, it skillfully adjusts motor speed while maintaining the motor's torque intact. This intuitive regulation method ensures consistent system pressure, providing compressed air perfectly matched to demand. Should air consumption decline, the compressor's output reverts to innovation as the inverter gracefully reduces motor speed, consequently tapering off compressed air production. On the flip side, by elegantly boosting the motor speed, the system can augment compressed air provision, maintaining stability and seamless system equilibrium.

Harnessing state-of-the-art vector control technology, these units operate effortlessly over an expansive speed range, all while ensuring minimal motor temperature increase. This harmonious synergy delivers the precise torque essential for uninterrupted air compressor operation. Vector control deftly splits motor current into torque and other components, ensuring optimal current distribution and empowering the motor with maximum torque output, even amid voltage fluctuations at the motor's endpoint, all while sustaining consistent current levels. This intelligent responsiveness assures that the motor operates at its peak performance with outstanding efficiency.


Advantages of Permanent Magnet Variable Frequency Screw Air Compressor

High Efficiency and Energy Saving
Through sophisticated frequency conversion regulation, every watt is judiciously harnessed to sync power consumption precisely with demand, optimizing energy use during air compression. This ensures operation that is both supremely efficient and environmentally friendly.

Cost Reducing
Leveraging the permanent magnet frequency conversion technology, energy costs dramatically reduce by over 35%, while cutting the compressor's lifecycle expenses by an average of 22%. The initial investment quickly self-amortizes within 1 to 2 years, offering a financially strategic choice.

Steady Pressure
With the masterful PID (Proportional, Integral, Derivative) control method, the compressor is precisely fine-tuned to maintain unwavering system pressure, guaranteeing operational precision and stability.

Life Extension
The frequency conversion start-up process minimizes impact on both the power grid and machinery, thus effectively extending equipment service life by significantly reducing wear and tear.

Top Quality
Featuring top-tier imported bearings and state-of-the-art rotor profile technology, these compressors, with their large rotors operating at low speeds, ensure reduced noise levels, enhanced efficiency, and superior production quality.
