Product Structure

 

Working Principle

A permanent magnet frequency conversion air compressor is an extraordinary innovation in engineering. It leverages a highly sensitive pressure sensor to accurately detect real-time system pressure and air consumption. The seamless blend of electric and frequency converter control perfectly adjusts the motor speed while maintaining the same motor torque. This smart adjustment consistently maintains the system pressure, delivering compressed air that precisely matches demand. When air consumption decreases, the compressor's output exceeds the requirement, prompting the advanced inverter to skillfully reduce motor speed and thus curtail compressed air output. Conversely, by smoothly accelerating the motor, the system can increase compressed air supply to stabilize pressure, ensuring a perfect balance and seamless system operation.

By leveraging state-of-the-art vector control technology, these units operate effortlessly across a wide speed range, ensuring that motor temperature rise is minimal. This remarkable synergy results in the ideal torque needed for the smooth operation of the air compressor. Vector control accurately separates motor current into torque and other components, ensuring optimal current distribution. This allows for maximum torque output even during voltage drops at the motor end, all while maintaining consistent current levels. This intelligent responsiveness ensures that the motor operates at peak efficiency.


Advantages of Permanent Magnet Variable Frequency Screw Air Compressor

High Efficiency and Energy Saving
Thanks to frequency conversion regulation, power consumption perfectly aligns with operational demands, optimizing energy usage for air compression. This meticulous alignment ensures that every watt of energy is used efficiently, making operations not only economical but also environmentally friendly by their very design.

Cost Reducing
Through the adoption of permanent magnet frequency conversion technology, energy expenses can be reduced by over 35%. Additionally, the compressor's life cycle costs are trimmed by an average of 22%, offering significant savings. The initial investment is quickly recuperated within 1 to 2 years, making it an astute financial decision.

Steady Pressure
The PID (Proportional, Integral, Derivative) control method is adept at fine-tuning the compressor, ensuring unwavering system pressure for precision and stability during operation.

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

Top Quality
By utilizing premium imported bearings and incorporating advanced rotor profile innovations, these compressors feature large rotors with substantial displacement operating at low speeds. This results in reduced noise, enhanced efficiency, and superior production quality, setting a benchmark of excellence.
