With the improvement of the level of automation boiler, auxiliary boiler influence and control systems for boiler safety, energy-saving operation is increasing.

Fever is often the early signs of damage or malfunction to the auxiliary power unit motor, for example, by the infrared camera can be found in the following issues:

1) Electrical wiring loose, Shandong pump terminals oxidation corrosion, tight terminal connections cause overheating.

2) unbalanced voltage or cable overload caused by overheating.

3) The air flow is not sufficient cause cooling failure, internal core, the winding insulation due to aging housing portion zone temperature short circuit damage caused by too high.

4) Not to poor lubrication caused the bearing Sichuan vacuum pump or shaft coupling temperature is too high.

Process destroys boiler control cabinet electrical components has an evolving, abnormal heat generation components or connection points will appear. For example: bad header, bolts, washers, not pressed or too tight, make a conductive area is reduced and heat; long run oxidation corrosion increases the resistance, abnormal heat; instability or excessive load current, three-phase imbalance or overload, intermediate meet fever exception.
