In today's air compressor industry, the market share of permanent magnet variable frequency air compressors is higher than that of ordinary screw air compressors and oil-free air compressors. Why is permanent magnet variable frequency air compressor so popular in the air compressor market? It is mainly due to its following advantages:
1Start without shock
The inverter of the permanent magnet variable frequency air compressor has a soft start function, and the impact force on the machine is very small when starting.
2. Low noise
In most cases, permanent magnet variable frequency air compressors work below the rated speed for hours, which will greatly reduce the noise and wear of the main engine, thereby extending the maintenance time and service life of the machine.
3. Stable air pressure
Since the permanent magnet variable frequency air compressor utilizes the invincible speed regulation characteristics of the frequency converter, it can start smoothly and slowly through the PID regulator of the controller or internal regulator, and can quickly respond to occasions with large fluctuations in gas consumption.
4. Variable flow control
We all know that the power frequency air compressor can only work at one exhaust volume, but the variable frequency air compressor is different. It can work in a wider range of exhaust volumes. The inverter adjusts the motor speed in real time according to the actual gas consumption to control the exhaust volume. When the gas consumption is low, the air compressor can also be automatically put into sleep mode, which greatly reduces energy loss. The optimized control strategy can further improve the energy saving effect.
The above are the main advantages of permanent magnet variable frequency screw air compressor, and also the main reason why it can gain a foothold in the market.
