How does the air compressor frequency converter work?

The air compressor inverter is the key equipment to control the running speed of the air compressor motor. Its working principle is to adjust the motor speed by changing the power frequency of the motor input, so as to realize the precise control of the air compressor output volume.

Specifically, the frequency converter first rectifies the alternating current of the power grid into direct current, and then converts the direct current into alternating current with adjustable frequency through the inverter and supplies it to the motor. By adjusting the AC frequency of the inverter output, the speed of the motor can be controlled, thereby controlling the compression ratio and output volume of the air compressor.

In addition, the inverter usually has a variety of protection functions, such as overload protection, over-current protection, under-voltage protection, etc., to ensure the safe operation of the motor and air compressor.

Question: How does the variable frequency air compressor of Shanghai Granklin Group achieve precise control of the output gas volume?

Answer: The variable frequency air compressor of Shanghai Granklin Group is equipped with advanced frequency converter to realize the precise control of the output gas volume. The frequency converter can change the power frequency of the motor input to adjust the speed of the motor. When the required gas volume decreases, the frequency converter can reduce the motor speed, reduce the compression ratio, and reduce the output gas volume; conversely, when the required gas volume increases, the frequency converter can increase the motor speed, increase the compression ratio, and increase the output gas volume. This precise control method can not only meet different production needs, but also effectively save energy and improve the operating efficiency of the equipment.
