Working Principle
A permanent magnet frequency conversion air compressor artfully employs a sophisticated pressure sensor to swiftly gauge real-time system pressure and air usage. Thanks to the dexterous control by the electric and frequency converter, it dynamically modulates the motor speed while maintaining the torque of the air compressor motor constant. This intelligent regulation ensures the compressed air output is perfectly aligned with demand. When system air consumption falls, the compressor's output surpasses the requirement, prompting the inverter to seamlessly decelerate the motor, thus reducing air output. Conversely, as air consumption surges, the motor speed is gracefully accelerated, enhancing air output to sustain stable system pressure with finesse.
Harnessing the power of cutting-edge vector control technology, this compressor operates seamlessly across an expansive range of speeds, all while ensuring minimal motor temperature increase. This advanced technology guarantees that the motor delivers the requisite torque to drive the air compressor effortlessly. The motor current, comprising the torque-generated component by the motor, is astutely managed by vector control technology. This ensures optimal compensation for voltage drops at the motor end, enabling maximum torque output without necessitating increased current usage.
Advantages of Permanent Magnet Variable Frequency Screw Air Compressor
High Efficiency and Energy Saving
The frequency conversion regulation of this compressor notably curtails actual power consumption, ensuring energy is adeptly utilized for air compression. This translates into remarkable energy efficiency and substantial cost savings, making it a top choice for energy-conscious operations.
Cost Reducing
Through its groundbreaking permanent magnet frequency conversion technology, energy costs are dramatically slashed by over 35%, and the compressor's life cycle costs reduced by an average of 22%. The additional investment in this state-of-the-art compressor can be recovered within 1 to 2 years, rendering it a prudent and economical investment.
Steady Pressure
By deploying the sophisticated PID (proportional, differential, integral) method, this advanced compressor guarantees meticulous adjustment to sustain stable system pressure, thereby enhancing overall operational reliability and consistency.
Life Extension
Frequency conversion starts significantly mitigate the impact on power grids and machinery, substantially extending the equipment's service life. This leads to minimized downtime and reduced maintenance expenses, maximizing operational efficiency.
