Screw air compressor permanent magnet frequency conversion technology has a number of advantages, the following is a detailed summary of its characteristics:
high efficiency and energy saving: advanced gas control technology is adopted. Compared with traditional air compressors, permanent magnet frequency conversion of screw air compressors can output 20% ~ 30% more gas flow under the same exhaust pressure. At the same time, under the same gas flow, the power consumption is significantly reduced, which helps to save a lot of electricity and reduce operating costs.
Wide range of flow control: the power frequency driven air compressor usually can only work in a fixed displacement, while the screw air compressor permanent magnet frequency conversion can work in a wide range of displacement. The frequency converter can adjust the motor speed in real time according to the actual demand, so as to control the displacement. When the air consumption is low, the air compressor can also automatically enter the dormant state, further reducing energy loss.
Starting impact is small: because the inverter itself contains the function of soft starter, the maximum starting current is only 1.2 times of the rated current, which is far less than 6 times of the power frequency starting, so the impact on the power grid and the entire mechanical system is greatly reduced.
Low noise: In most working conditions, the permanent magnet frequency conversion of the screw air compressor works below the rated speed, which helps to reduce the mechanical noise and wear of the host, thereby extending the maintenance cycle and service life of the air compressor.
Good power supply adaptability: As the frequency converter adopts over-modulation technology, the permanent magnet frequency conversion of the screw air compressor can still output enough torque to drive the motor when the AC power supply voltage is slightly lower. At the same time, when the voltage is slightly higher, the voltage output to the motor will not be too high.
In summary, the permanent magnet frequency conversion technology of screw air compressor has the advantages of high efficiency and energy saving, wide range flow control, small starting impact, low noise and good power supply adaptability. It is suitable for various occasions that require stable and efficient air compression.
