How to see whether the screw air compressor is frequency conversion type
The simplest point is to see whether it contains a frequency converter, and the second is to see whether the motor changes its speed according to the actual working conditions during operation. There are many factors to look. Speed directly affects the oil pressure and high and low pressure. I can see whether there is frequency conversion in current or not. Literally understood, the speed of the variable frequency air compressor is almost the same as the fixed frequency under the working state. When the air compressor is not in the pumping state, the motor frequency will automatically drop and the input power will be reduced to achieve the effect of energy saving.
