What is the effect of permanent magnet variable frequency air compressor‘

The permanent magnet variable frequency screw air compressor is the hottest air compressor product in the air compressor market, and it is the focus of attention of the majority of businesses and users. Users with increasing awareness of energy conservation tend to purchase permanent magnet variable frequency air compressors to replace energy-efficient air compressor products. So, what are the characteristics of permanent magnet variable frequency air compressors? What is the effect of permanent magnet variable frequency air compressor?

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

　　The biggest feature of permanent magnet variable frequency air compressor is energy saving. Aigao 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.

　　 2. 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.

　　3. The main unit and 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.

　　 4. Start without inrush current

　　 The inverter itself covers the soft-start function, the starting current z* 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.
