1.变频器操控电(dian)机(ji)(ji)与(yu)传统(tong)操控电(dian)机(ji)(ji)比较，动力节省是zui有实(shi)际意义的(de)，根(gen)据注水量、输水量需(xu)求自动调整电(dian)机(ji)(ji)zui经(jing)济的(de)作业(ye)情况，即可节电(dian)50%。

2．作(zuo)业(ye)(ye)本(ben)(ben)(ben)钱(qian)(qian)下(xia)降(jiang)，传统电机(ji)(ji)的(de)作(zuo)业(ye)(ye)本(ben)(ben)(ben)钱(qian)(qian)由三项组成：初始收(shou)买本(ben)(ben)(ben)钱(qian)(qian)、保护(hu)本(ben)(ben)(ben)钱(qian)(qian)和(he)动力(li)(li)本(ben)(ben)(ben)钱(qian)(qian)。其间(jian)动力(li)(li)本(ben)(ben)(ben)钱(qian)(qian)大约占电机(ji)(ji)作(zuo)业(ye)(ye)本(ben)(ben)(ben)钱(qian)(qian)的(de)77%。通过(guo)动力(li)(li)本(ben)(ben)(ben)钱(qian)(qian)下(xia)降(jiang)44.3%，再加(jia)上变(bian)频发起后对(dui)设备的(de)冲(chong)击减少，保护(hu)和(he)维(wei)修(xiu)量也随从(cong)下(xia)降(jiang)，所(suo)以作(zuo)业(ye)(ye)本(ben)(ben)(ben)钱(qian)(qian)将大大下(xia)降(jiang)。

3．提高压(ya)力(li)(li)(li)操控(kong)精度(du)，变(bian)频操控(kong)系统(tong)(tong)具(ju)有(you)精准(zhun)的(de)(de)(de)压(ya)力(li)(li)(li)操控(kong)能力(li)(li)(li)。使(shi)设备(bei)的(de)(de)(de)压(ya)力(li)(li)(li)输出(chu)与系统(tong)(tong)所(suo)设的(de)(de)(de)注(zhu)水(shui)量相匹配。变(bian)频操控(kong)设备(bei)的(de)(de)(de)输出(chu)量跟着(zhe)电机转(zhuan)速的(de)(de)(de)改(gai)动(dong)(dong)而改(gai)动(dong)(dong)。因为变(bian)频操控(kong)电机速度(du)的(de)(de)(de)精度(du)提高，所(suo)以它能够使(shi)管网的(de)(de)(de)系统(tong)(tong)压(ya)力(li)(li)(li)改(gai)变(bian)保持在0.2kg改(gai)变(bian)范围内(nei)，有(you)效(xiao)地(di)提高了作业(ye)效(xiao)率同时也大大节(jie)省动(dong)(dong)力(li)(li)(li)。

4．延(yan)伸电(dian)(dian)(dian)机(ji)的使(shi)用寿(shou)命，变频(pin)器从0Hz发(fa)起(qi)(qi)(qi)(qi)电(dian)(dian)(dian)机(ji)，它的发(fa)起(qi)(qi)(qi)(qi)加速时(shi)间能够调整，然(ran)后减少发(fa)起(qi)(qi)(qi)(qi)时(shi)对电(dian)(dian)(dian)机(ji)的电(dian)(dian)(dian)器部件和机(ji)械部件形成的冲击，增强系(xi)统的可靠性(xing)，使(shi)电(dian)(dian)(dian)机(ji)的使(shi)用寿(shou)命延(yan)伸。此外，变频(pin)操控能够减少机(ji)组(zu)发(fa)起(qi)(qi)(qi)(qi)时(shi)电(dian)(dian)(dian)流动(dong)摇，这(zhei)一动(dong)摇电(dian)(dian)(dian)流会影响(xiang)电(dian)(dian)(dian)网(wang)和其他设备的用电(dian)(dian)(dian)，变频(pin)器能够有效地将发(fa)起(qi)(qi)(qi)(qi)电(dian)(dian)(dian)流的峰值减少到zui低(di)程度。

5．变频(pin)操控情况下(xia)(xia)下(xia)(xia)降了电机的(de)噪(zao)音，根据工况要求变频(pin)调速(su)后，电机有效，均(jun)速(su)，平稳的(de)作业(ye)，因此大(da)大(da)地下(xia)(xia)降了电机作业(ye)时的(de)噪(zao)音。
