5 energy-saving advantages of permanent magnet variable frequency air compressor

With the continuous progress of society and the development of science, energy conservation has become more and more a topic of concern. Permanent magnet variable frequency air compressors have been used more and more in industrial production, and power frequency-driven air compressors have gradually withdrawn from the attention of users.

　　 Speaking of permanent magnet variable frequency air compressors, we think of energy saving the first time. So what are the energy-saving aspects of permanent magnet variable frequency air compressors?

　　 1. The main unit and the motor are integrated shaft type

　　The transmission efficiency is 100%, no coupling, no gear, no belt transmission. Permanent magnet motors do not require bearings, maintenance, and lubricants, which can eliminate fault points and reduce maintenance costs. Ordinary asynchronous motors often experience failures such as bearing wear and coil burning, and high maintenance costs.

　　2. Energy saving effect of permanent magnet variable frequency air compressor

　　The biggest feature of permanent magnet variable frequency air compressor is energy saving. The okmarts.com permanent magnet variable frequency screw air compressor generally has an energy-saving effect of 33% and above. It mainly depends on the working conditions and the parameters of the inverter. When the customer's air pressure is unstable and fluctuates greatly, the energy-saving effect will be better.

　　3. Air pressure is stable

　　 Because the frequency conversion screw air compressor uses the stepless speed regulation feature of the frequency converter, it can start smoothly through the controller or the PID regulator inside the frequency converter, and can quickly adjust the response to the occasions with large fluctuations in air consumption.

　　 4. Start without inrush current

　　The inverter itself covers the soft start function, the maximum starting current is within 2 times of the rated current, and the starting impact is small. The power frequency start is generally more than 6 times the rated current. When the power grid capacity of the factory is limited, the air compressor switch will trip. Not only the impact on the power grid, but also on the entire mechanical system is greatly reduced.

　　5. Variable flow control

　　 Ordinary power frequency air compressors can only work at one displacement, while permanent magnet variable frequency air compressors can work in a relatively wide range of displacements. According to the actual air consumption, the motor speed is automatically adjusted in real time and the exhaust volume is controlled. Produce as much gas as you use, and when the gas consumption is low, the air compressor can automatically sleep, which greatly reduces energy loss.
