永磁变频空压机气压稳定
1、 Air pressure stability of permanent magnet frequency conversion 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。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。
Because the variable frequency screw air compressor makes use of the stepless speed regulation characteristics of the frequency converter, it can start smoothly through the controller or the PID regulator inside the frequency converter; In case of large fluctuation of gas consumption, it can quickly adjust the response. Compared with the upper and lower limit switch control of power frequency operation, the air pressure stability is improved exponentially.
二、永磁变频空压机启动无冲击
2、 Permanent magnet frequency conversion air compressor starts without impact
由于变频器本身含概了软启动器的功能,启动电流较大在额定电流的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。这种冲击不仅是对电网的,对整个机械系统的冲击,也大大减少。
Since the frequency converter itself includes the function of soft starter, the starting current is large, within 1.2 times of the rated current, and the starting impact is very small compared with that of power frequency starting, which is generally more than 6 times of the rated current. This impact is not only to the power grid, but also to the whole mechanical system, but also greatly reduced
