一、永磁变频空压机气压稳定

1. Atmospheric pressure stabilization of permanent magnet variable frequency air compressor

由于变频化的螺杆空压机利用了变频器的无级调速特点，通过控制器或变频器内部的PID调节器，能平缓启动;对用气量波动比较大的场合，又能快速调节响应。

As the variable frequency screw compressor uses the stepless speed regulation of the frequency converter, it can be started slowly through the controller or the PID regulator inside the inverter, and the response can be quickly adjusted to the situation where the gas fluctuation is relatively large.

与工频运行的上下限开关控制相比，气压稳定性成指数级的提高。

Compared with the upper and lower limit switch control of power frequency operation, the stability of air pressure increases exponentially.

二、永磁变频空压机启动无冲击

Two. The permanent magnet variable frequency air compressor starts without shock

由于变频器本身含概了软启动器的功能，启动电流在额定电流的1.2倍以内，与工频启动一般在额定电流的6倍以上相比，启动冲击很小。

Because the inverter itself contains the function of the soft starter, the maximum starting current is within 1.2 times of the rated current, and the startup impact is small compared with the rated current 6 times more than the rated current.
