  5、 杜绝无用功损耗 Prevention of Busywork Loss

  通过压力传感器检测排气口的压力,把压力信号传输给PLC,PLC根据压力传感器反馈信号来控制变频器的输出频率,实现无级变频调速。当压力升高时,降低输出频率;当压力降低时,提高输出频率,实现恒压供气。多用少气产多少气,如系统不用气则空压机会自动休眠,一旦系统压力有波动立即平滑实现软启动开始产气,彻底杜绝了无用功的能源损耗。

  The pressure sensor detects the pressure of the outlet, and transfers the signal to PLC. The PLC then controls the output frequency of the inverter, achieving the continual variable frequency. Once the pressure goes higher, it lowers the output frequency; once the pressure goes lower, it raises the output frequency. When the system needs no air, the inverter comes to sleep mode. Once the system pressure fluctuates, the soft starter smoothly produces air, completely preventing energy waste.
