Working Principle
A permanent magnet frequency conversion air compressor utilizes a state-of-the-art pressure sensor to swiftly and accurately gauge the real-time system pressure and the air consumption levels. With precision control executed by the electric and frequency converter, it adjusts the motor speed without altering the torque of the air compressor motor, ensuring that the compressed air output meets demand perfectly. When there's a dip in system air consumption and the compressor's output exceeds requirements, the inverter steps in to slow down the motor, subsequently reducing the air output. Conversely, an increase in air consumption triggers the motor to accelerate, thereby boosting air output to uphold a stable and consistent system pressure.
Harnessing the power of pioneering vector control technology, this compressor operates with exceptional efficiency across a diverse range of speeds, all the while minimizing any rise in motor temperature. This groundbreaking technology ensures the motor produces the essential torque needed for seamless operation of the air compressor. The motor current, which comprises the torque component generated by the motor, is effectively distributed via vector control technology. This smart distribution allows for optimal compensation for voltage drops at the motor's end, thereby enabling maximum torque output without a concurrent rise in current usage.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Saving
The frequency conversion regulation dramatically diminishes the compressor's actual power consumption, ensuring that energy is utilized with utmost efficacy for air compression. This translates into remarkable energy efficiency and substantial cost savings, making it an undeniable asset.
Cost Reducing
Thanks to the revolutionary permanent magnet frequency conversion technology, energy costs are slashed by more than 35%, while the compressor's life cycle cost sees a reduction of around 22%. The upfront investment in this cutting-edge compressor pays for itself within a short span of 1 to 2 years, rendering it a wise and economical investment.
Steady Pressure
Incorporating the PID (proportional, differential, integral) method, this sophisticated compressor achieves precise adjustments to maintain stable system pressure, thereby elevating overall operational dependability.
Life Extension
By significantly diminishing the impact on power grids and machinery, frequency conversion starts lead to a substantial extension of the equipment's service life. This results in minimized downtime and significantly reduced maintenance costs.
Top Quality
Engineered with the highest quality imported bearings and underpinned by the latest rotor profile research, this compressor boasts a large rotor, substantial displacement, low speed, and low noise. These exceptional features collectively bolster efficiency and uplift production quality, guaranteeing unmatched performance at every turn.
