I'm thinking about a predictive maintenance of boiler draft fans, but what are the causes of abnormalities in the first place?
我在考虑锅炉通风机的预测性维护, 导致异常的原因究竟是什么呢?
The causes could be from vibrations or performance loss of the boiler draft fans.
可以考虑锅炉通风机的振动、性能劣化等原因。
Well then, how can we prevent abnormalities before they occur?
那么,该怎样做才能将异常防患于未然?
For example, in the case of vibrations, you can prevent abnormalities by observing changes in the vibrations with a sensor over time and changes over the years.
