Abstract： This paper analyzes the development process and status quo of the fault diagnosis technology of vertical water pump unit. Several common fault detection methods of vertical water pump unit are introduced in detail from the analytical model-based processing method， signal based processing method and knowledge based processing method three aspects. The advantages and disadvantages of these methods are analyzed and summarized， which provides some theoretical methods for fault diagnosis of large and medium-sized vertical water pump units.

Keywords： vertical water pump unit; fault diagnosis; vibration detection method
