Working Principle
A permanent magnet frequency conversion air compressor employs a sophisticated pressure sensor to instantly detect the real-time pressure and air consumption within the system. Utilizing precise control via an electric and frequency converter, it adeptly adjusts the motor speed without altering the motor's torque, thereby regulating system pressure to match the demand for compressed air. As system air consumption drops, the compressor, producing more air than needed, will reduce its rotational speed, decreasing the output of compressed air. Conversely, if the demand rises, it accelerates the motor speed to augment the compressed air output, ensuring a stable system pressure is consistently maintained.
Employing cutting-edge vector control technology, the unit operates seamlessly across a wide range of speeds while minimizing motor temperature rise. This ensures the motor delivers the necessary torque smoothly to drive the air compressor. The motor current, which consists of the torque component and other vectors, is meticulously managed by this technology. It optimally adjusts current values to maintain peak performance. In response to voltage drops at the motor's end, vector control technology compensates efficiently, enabling the motor to deliver maximum torque without increasing current.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Saving
Frequency conversion regulation significantly reduces the actual power consumption of the compressor, channeling energy efficiently into air compression for remarkable savings.
Cost Reducing
By leveraging permanent magnet frequency conversion technology, energy costs are slashed by over 35%, with the overall lifecycle cost of compressors reduced by an average of 22%. This added investment in the compressor pays for itself within just 1 to 2 years.
Steady Pressure
The PID (Proportional-Integral-Derivative) control method is utilized to fine-tune the compressor, ensuring the system pressure remains stable and consistent.
Life Extension
Frequency conversion starting reduces the impact on the power grid and mechanical components, significantly extending the service life of the compressor.
Top Quality
Incorporating top-quality imported bearings and the latest rotor profile technology, the compressor features a large rotor, substantial displacement, low speed, and low noise, enhancing both efficiency and production quality.
