Screw air compressor is now a kind of energy-saving air compressor, and the advantages of variable frequency air compressor are:
1) The air pressure is stable, because the frequency conversion screw air compressor uses the stepless speed regulation characteristics of the frequency converter, and through the PID adjustment of the controller or the inverter, the pressure can be quickly adjusted and controlled, and the upper and lower limit switch control of the power frequency operation is controlled. In comparison, the pressure stability increases exponentially.
2) It is more energy-efficient. Although various air compressors of various manufacturers adopt different energy-saving operation modes, since the inverter actually adjusts the motor speed according to the actual air consumption, the air compressor can automatically sleep when the air volume is low. This will greatly reduce the loss of energy.
3) Start without impact, as the inverter itself is a soft-start device, the starting current is at most about twice the rated current, compared with the power frequency startup is generally more than 6 times the rated current, the starting impact is small, this impact is not only As for the power grid, there is also an impact on the entire mechanical system, which is also greatly reduced.
4) Low noise, because the operating frequency is less than the power frequency during stable operation, the mechanical noise is reduced, and the mechanical wear is small
5) The requirement for the capacity of the gas storage tank The frequency conversion air compressor is also now widely used energy-saving equipment, and the frequencies appearing in the market are continuously increasing.
