A kind of mechanical Fault Monitoring of HV device embodiment 2 of packaging facilities
Failure whether is there occurs in order to effectively monitoring device, the selection of measuring point also seems particularly significant.On the one hand,
When the measure-point amount of selection is more, it will necessarily make it that the quantity and analytical parameters that introduce sensor become many, this accordingly can be filled in increase
The cost put；On the other hand, when the measure-point amount of selection is less, it is possible to some important informations can be neglected so that device is not
Being capable of failure judgement well.The position of can selection measuring point and monitoring parameter directly affects the monitoring of device and examine
Disconnected effect.
For example for GDX2 packaging machines, in practical application, one in following seven measuring points can be chosen or many
It is individual to be monitored as specific measuring point (as without special declaration, being generally two or more)：
