Screw air compressor adopts frequency control of motor speed good?

Screw air compressor adopts frequency control of motor speed what good? Let’s take a look.

The pressure stability
Due to the frequency of screw air compressor using the stepless speed regulation characteristics of frequency converter, through the inside of the controller or inverter PID regulator, can realize the rapid adjustment of pressure control. Than compared to run on lower limit switch control, power frequency pressure stability increase exponentially.
More energy efficient
Although each manufacturer of screw air compressor has taken a different energy saving operation mode, but due to the frequency converter is based on the actual gas real-time adjust the motor speed, low gas can also let air compressor automatically, thus greatly reduce the energy loss. It is important to note that the system control mode has a great influence on the energy saving effect.
No impact on the start
Because the inverter itself is a soft start device, starting current biggest at about twice the rated current, and power frequency start generally in more than 6 times of the rated current, compared to start the impact is very small. The impact is not only to the grid, also have impact on the whole mechanical system, also greatly reduced.
Low noise
Due to the stable operation of running frequency is less than the power frequency, mechanical noise, low mechanical wear and tear.
