| Abstract: | Against the fault of bearing burning of the pump motors in thermal circulating system outside the power plant,analysis was done in the fields of motor construction, axial expansion,oneway magnetic strength and axial pull by the pump operation,so as to find out the cause of it. The shaft was rebuilt,and then,the heating of bearings was eliminated. |
