Working Principle
The permanent magnet frequency conversion air compressor is an innovative marvel that utilizes a pressure sensor to instantly detect actual use pressure and air consumption within the system. Through the precise control of electric and frequency converters, it dynamically adjusts the motor speed without changing the torque of the air compressor motor. This advanced mechanism regulates the system pressure, ensuring the output of compressed air is perfectly aligned with demand. When system air consumption decreases, the compressor's inverter reduces the rotational speed, thereby decreasing the amount of compressed air output. Conversely, it increases the motor's rotational speed to elevate the amount of compressed air, maintaining a stable system pressure.
By adopting cutting-edge vector control technology, the unit operates seamlessly across a wide range of speeds while minimizing motor temperature rise. This ensures optimal torque to drive the air compressor smoothly. The motor current, comprised of the torque component and other vector control elements, is meticulously distributed to determine the values of the motor's current components. Vector control techniques adeptly compensate for voltage drops at the motor end, enabling the motor to output maximum torque without increasing the current.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Saving
Frequency conversion regulation significantly reduces actual power consumption in proportion to the frequency conversion compressor's operation. This ensures that energy is effectively utilized for air compression, enhancing overall efficiency.
Cost Reducing
The advanced permanent magnet frequency conversion technology slashes energy costs by over 35%, while reducing the life cycle cost of compressors by an average of 22%. The additional investment in the compressor can be recouped within a short span of 1 to 2 years.
Steady Pressure
Utilizing the PID (proportional, differential, integral) method, the exclusive compressor is finely tuned to maintain system pressure stability with precision and reliability.
Life Extension
Frequency conversion startup minimizes the impact on the power grid and mechanical components, significantly extending the service life of the equipment.
Top Quality
Employing top-quality imported bearings and the latest advancements in rotor profile design, this compressor boasts a large rotor, substantial displacement, low speed, and low noise. These features collectively enhance efficiency and production quality, setting a benchmark for excellence in the industry.
