1.变频器操控(kong)电机与传统操控(kong)电机比较，能源(yuan)节约是(shi)zui有实际意义的，根据注水量、输水量需(xu)求主(zhu)动调(diao)整电机zui经(jing)济的运转状(zhuang)况，即(ji)可节电50%

2．运转本(ben)(ben)(ben)钱(qian)(qian)下(xia)降(jiang)，传统电(dian)机的(de)运转本(ben)(ben)(ben)钱(qian)(qian)由三项组成(cheng)：初始采购本(ben)(ben)(ben)钱(qian)(qian)、保(bao)护本(ben)(ben)(ben)钱(qian)(qian)和能(neng)(neng)源本(ben)(ben)(ben)钱(qian)(qian)。其中能(neng)(neng)源本(ben)(ben)(ben)钱(qian)(qian)大(da)约占电(dian)机运转本(ben)(ben)(ben)钱(qian)(qian)的(de)77%。经过能(neng)(neng)源本(ben)(ben)(ben)钱(qian)(qian)下(xia)降(jiang)44.3%，再(zai)加(jia)上(shang)变频发动后对设备(bei)的(de)冲击削减(jian)，保(bao)护和维修(xiu)量也跟随下(xia)降(jiang)，所以运转本(ben)(ben)(ben)钱(qian)(qian)将大(da)大(da)下(xia)降(jiang)。

3．进(jin)步压(ya)力(li)(li)操控(kong)精度(du)，变(bian)(bian)频(pin)操控(kong)体系(xi)具(ju)有精准的压(ya)力(li)(li)操控(kong)能(neng)力(li)(li)。使设备的压(ya)力(li)(li)输出与(yu)体系(xi)所(suo)设的注水量相匹配(pei)。变(bian)(bian)频(pin)操控(kong)设备的输出量随着电(dian)机(ji)(ji)转速(su)的改动而改动。因为变(bian)(bian)频(pin)操控(kong)电(dian)机(ji)(ji)速(su)度(du)的精度(du)进(jin)步，所(suo)以(yi)它可(ke)以(yi)使管网的体系(xi)压(ya)力(li)(li)变(bian)(bian)化保持(chi)在0.2kg变(bian)(bian)化范围内，有效(xiao)(xiao)地(di)进(jin)步了(le)作业效(xiao)(xiao)率一起也大大节约能(neng)源。

4．延伸电(dian)(dian)(dian)(dian)机(ji)的使用(yong)寿命，变频器从(cong)0Hz发(fa)(fa)(fa)动(dong)(dong)电(dian)(dian)(dian)(dian)机(ji)，它(ta)的发(fa)(fa)(fa)动(dong)(dong)加速时(shi)(shi)刻可以(yi)调整，然后(hou)削减发(fa)(fa)(fa)动(dong)(dong)时(shi)(shi)对电(dian)(dian)(dian)(dian)机(ji)的电(dian)(dian)(dian)(dian)器部件和机(ji)械部件形(xing)成的冲击，增强(qiang)体系(xi)的可靠性，使电(dian)(dian)(dian)(dian)机(ji)的使用(yong)寿命延伸。此外，变频操控可以(yi)削减机(ji)组发(fa)(fa)(fa)动(dong)(dong)时(shi)(shi)电(dian)(dian)(dian)(dian)流(liu)波动(dong)(dong)，这(zhei)一波动(dong)(dong)电(dian)(dian)(dian)(dian)流(liu)会(hui)影响电(dian)(dian)(dian)(dian)网和其他设(she)备的用(yong)电(dian)(dian)(dian)(dian)，变频器可以(yi)有(you)效地(di)将发(fa)(fa)(fa)动(dong)(dong)电(dian)(dian)(dian)(dian)流(liu)的峰(feng)值削减到(dao)zui低程度。

5．变频(pin)操控(kong)状况下下降了(le)电(dian)机(ji)的噪(zao)音，根据工况要(yao)求变频(pin)调速后，电(dian)机(ji)有效，均速，平稳的作(zuo)业，因(yin)而大(da)大(da)地下降了(le)电(dian)机(ji)运转时(shi)的噪(zao)音。
