What is the energy-saving effect of permanent magnet variable frequency screw 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 is the energy-saving effect of permanent magnet variable frequency screw air compressor?

　　 1. The biggest feature of permanent magnet variable frequency air compressor is energy saving. The general energy saving effect reaches 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. The 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. It can also be used for occasions with large fluctuations in air consumption. Quickly adjust response.

　　3, the main engine and motor integrated shaft transmission efficiency is 100%, no coupling, no gear, no belt drive. Permanent magnet motors do not require bearings, maintenance, and lubricants, which eliminates the point of failure and reduces maintenance costs. Ordinary asynchronous motors often suffer from bearing wear and lead to coil burning and other failures, and maintenance costs are high.

　　4. Start non-impact 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 industrial frequency air compressors can only work in one displacement, while permanent magnet variable frequency air compressors can work in a relatively wide range of displacement. 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. When the gas consumption is low, the air compressor can automatically sleep, which greatly reduces energy loss.
