Abstract :
Dish centrifugal separator is a kind of high speed rotary machine, which is widely used in rubber, pharmacy and food industry. Any fault of rotary part could bring about separator´s strong vibration and noise. Not only can the strong vibration debase machine´s separating efficiency, but it can also affect operator´s health. Condition monitoring by vibration is a proper way to reduce loss brought by separator´s faults. For dish centrifugal separator, helical gear´s condition is closely related to separator´s working state. In this paper, main faults of dish centrifugal separator´s helical gear are described. In order to analyze the dish centrifugal separator´s vibration with different.
