Research on abnormal sound fault of centrifugal oil pump for transformer
Aiming at the abnormal sound phenomenon of centrifugal oil pump for transformer in the process of high-speed operation,by analyzing the internal structure of the oil pump and studying the fault mechanism,the solution of induction heating assembly for the abnormal sound caused by the abnormal assembly of bearings was put forward.The measured results showed that the optimization of oil pump bearing assembly process did not affect the electrical performance of oil pump,but could eliminate the abnormal sound of oil pump caused by the failure of oil pump bearing assembly,and improve production efficiency and save production cost.
