The reason why permanent magnet frequency conversion air compressor is welcomed by the market

In recent years, industrial frequency air compressors are gradually replaced or replaced by permanent magnet variable frequency air compressors, which consume a lot of energy and have the title of "electric tiger", while permanent magnet variable frequency air compressors have the characteristics of energy-saving and emission reduction, which can save cost for users. So, what is the difference between the permanent magnet frequency conversion air compressor and the power frequency air compressor?
First, stable air pressure

 1, Since the inverter screw air compressor makes use of the stepless speed regulation feature of the inverter, it can start smoothly through the PID regulator inside the inverter; it can also adjust the response quickly for the occasions where the air consumption fluctuates more.

 2, Compared with the upper and lower limit switch control of industrial frequency operation, the air pressure stability is improved exponentially.

Second, no shock start

 1, because the inverter itself contains a soft starter function, the start current is large within a certain range of the rated current, compared with the frequency starting generally on the rated current, the start impact is very small.

 2、The impact is not only on the power grid but also on the whole mechanical system, which is greatly reduced.

Third, variable flow control

 1、Industrial frequency-driven air compressor can only work in one exhaust volume, while a variable frequency air compressor can work in a wider range of exhaust volumes. The frequency converter is used to control the exhaust volume by adjusting the motor speed in real-time according to the actual air consumption.

 2, When the air consumption is low, the compressor can be put to sleep automatically, which greatly reduces the energy loss.

 3, The optimized control strategy can further achieve the energy-saving effect.

Fourth, the voltage adaptability of the AC power supply is better

 1, Because of the over modulation technology adopted by the inverter, it can still output enough torque to drive the motor when the AC power supply voltage is a little low; when the voltage is a little high, it will not cause the output voltage to the motor to be high.

 2, For the self-generating occasion, the inverter drive can show its advantages more.

 3, According to the characteristics of motor VF (the inverter air compressor works below rated voltage in an energy-saving state), it is effective for the site with the low grid voltage.

Fifth, low noise

 1, Most working conditions of the frequency conversion system are below the rated speed, which reduces the mechanical noise and wear of the host machine and prolongs the maintenance and service life.

 2, If the fan is also driven by frequency conversion, it can significantly reduce the noise when the air compressor is working. The difference between variable frequency and industrial frequency is obvious.
