Working Principle
In the realm of cutting-edge innovation, the permanent magnet frequency conversion air compressor stands as a pinnacle of advanced technology. This masterpiece is equipped with an extremely sensitive pressure sensor that precisely monitors the actual system pressure and air consumption in real time. By skillfully orchestrating the electric and frequency converter, the system deftly adjusts the motor speed, ensuring that the air compressor motor's torque remains consistently steady. This elegant regulation guarantees that the compressed air output is perfectly synchronized with demand at all times. When there is a dip in air consumption, the compressor's output surpasses the requirement, prompting the inverter to gently decelerate the motor, effectively reducing air output. Conversely, when there's an increase in air demand, the motor speed accelerates, augmenting air output to effortlessly maintain stable system pressure.
Harnessing the power of state-of-the-art vector control technology, this compressor operates with supreme efficiency over a broad spectrum of speeds, meticulously keeping motor temperature rise to a mere whisper. This groundbreaking technology ensures that the motor delivers the essential torque needed to drive the air compressor with unparalleled smoothness. Vector control technology intelligently allocates the motor current, derived from the torque component produced by the motor, to optimize compensation for voltage drops at the motor end. This allows for maximal torque output without increasing current usage, thereby elevating performance and bolstering reliability.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Saving
The transformational frequency conversion regulation notably diminishes the compressor's actual power consumption, ensuring energy is utilized with exceptional efficiency for air compression. This results in outstanding energy savings and significant cost reductions, positioning the compressor as a green and economically savvy option.
Cost Reducing
The revolutionary permanent magnet frequency conversion technology slashes energy costs by over 35%, while simultaneously reducing the compressor's life cycle cost by approximately 22%. The investment in this cutting-edge compressor can be recouped within a swift 1 to 2 years, making it a smart and economically sound choice for visionary enterprises.
Steady Pressure
Thanks to the implementation of the PID (proportional, differential, integral) method, this advanced compressor achieves precise adjustments that ensure stable system pressure, significantly boosting overall operational reliability and consistency.
Life Extension
The frequency conversion starts drastically mitigate the impact on power grids and machinery, significantly prolonging the equipment's service life. This results in decreased downtime and reduced maintenance costs, delivering exceptional long-term value and dependability.
