Variable frequency air compressor is one of the screw air compressor, here is an important part is inverter, frequency converter is a part of a driving system, in which the important components include ac motor, drive controller (that is, frequency converter) itself and the operation interface of frequency converter. The ac motor driven by the inverter is generally three-phase induction motor, some inverters can drive single-phase motor or special synchronous motor use, but the main drive three-phase induction motor, the cost is relatively cheap. The new energy-saving configuration saves electricity by 20% compared with the common power frequency machine.
Advantages
After frequency conversion transformation, the pressure of the air compressor is always kept at the required set working pressure, which can reduce the pressure by 10% compared with that before the transformation. According to the power consumption formula, this can save 10% energy after the transformation.The energy consumed during unloading operation is about 40% of that during loading and unloading. According to the average unloading time of about a quarter, this item can save about 10% energy.
