Power plant water pump is not only an important auxiliary equipment,but also its safe and economic operation is the key to stable operation of power plant generator. Power plant water pump failure rate is higher. Firstly,westudied the faults caused by vibration of the equipment in power plants and did corresponded analy-sis. Secondly,we conductde diagnosis based on the rule-based classification principle. Finally,the established rule of fault diagnosis is applied to the problem of a power plant condensate pump vibration to find the reason of the condensate pump vibration. There are important significance that through the pump fault diagnosis and nanlysis of the power plant, it can reduce the pump failure rate and ensure the normal operation of the unit state.
