造成无负压供水设备电机过热的原因主要是由于电压偏高或偏低、传动不畅、通风系统故障或机组故障造成电机过热。电机过热严重时会造成绝缘烧坏、转子断条等情况发生。因此，在发现电机过热时应采用气动其他动力方式，进行停机检修。电压原因造成的无负压供水设备电(dian)(dian)(dian)(dian)机(ji)(ji)过(guo)热(re)应对(dui)供(gong)(gong)电(dian)(dian)(dian)(dian)系(xi)统进(jin)行(xing)检查(cha)，通过(guo)恢复稳定供(gong)(gong)电(dian)(dian)(dian)(dian)解决电(dian)(dian)(dian)(dian)机(ji)(ji)过(guo)热(re)故(gu)障(zhang)(zhang)。另外传(chuan)动(dong)不畅(chang)也(ye)会造成电(dian)(dian)(dian)(dian)机(ji)(ji)过(guo)热(re)，由于电(dian)(dian)(dian)(dian)机(ji)(ji)与给水泵(beng)间的传(chuan)动(dong)不畅(chang)造成电(dian)(dian)(dian)(dian)动(dong)机(ji)(ji)负(fu)载过(guo)大，出现小马拉大车的现象，电(dian)(dian)(dian)(dian)机(ji)(ji)过(guo)载是(shi)温度升高。此种情况须(xu)及时进(jin)行(xing)检修(xiu)，以免造成无负(fu)压供(gong)(gong)水设备机(ji)(ji)组(zu)故(gu)障(zhang)(zhang)。
