使用变频器注意事项：
　　1：水泵转速调节范围不宜太大，通常不低于额定转速的50％，当转速低于50％水泵本身效率明显下降。在调频时应避开泵机组的机械共振效率，否则将损坏泵机组。
　　2、当电动机由变频切换至工频电网运行时，必须延时5s以上进行定速运行后接触器才自动合闸，以防操作过电压。
　　3、当电动机由工频电网切换至变频变频器供电运行时，必须延时10s后接触器再闭合，以防止电动机高速产生感应电势损坏电子器件。
    4：变频器使用环境温度不应太高，特别是*运行的水泵，可能损坏功率模块。　　
　　使用变频器的优点：
　　1：能够节省大量的电能，在使用变频器之前，泵类只能靠阀门来控制流量，而使用变频器后可以通过调整频率可以改变泵的转速，达到了改变流量的目的，同时使用变频器可以使生产设备处于*状态下运行，减小了氨水对阀门、管道的磨损。一般使电机转速在额定转速下。
　　2：延长了电动机的使用寿命，由于三相异步电动机的起步电流为额定电流的5—7倍，对电机寿命有很大的损伤。而变频器的启动时候一种软启动发式，保护了泵电机。
　　3：大大减轻操作人员的劳动强度，原来控制氨水流量只能靠倒阀来控制氨水流量，现在自动变频情况下可以通过现场压力—流量传感器反馈的信号自动调节，在手动情况下，也只需调节面板上的电位器来改变电机频率，方便易行。

　　4：减轻对电网谐波干扰，变频器反馈到电网的谐波是由无功功率，换流能量，谐波电流组成，使用变频器能使反馈到电网的谐波分量限制在允许的幅值范围内。
　　5：使用变频器后对电机有了可靠的保护，如过流、过压、欠压、缺相等保护。
