The plant no. 2 boiler induced draft fan A standby lubricating oil pump not suppress A 2019 - 06 - 06 1 equipment introduction: electric induced draft fan USES is the chengdu power machinery factory production of the AN static blade adjustable axial flow fan, motor for Shanghai electric manufacturing, including the fan bearing grease lubrication, compulsory motor bearing lubrication, motor station, by providing the following for induced draft fan station parameters: 2 the occurrence of the incident: June 11, 2004 16 # 2 furnace lubricating oil station induced draft fan for A lubricating oil pump for normal switch on A regular basis, by running B pump switch to the standby pump. But after A pump up two pump parallel operation, the pressure of the pressure gauge has not changed, so the judge A pump not weaken. 3 cause analysis: in the May 15 # 1 furnace of A and B induced draft fan pump to switch the two wind turbine A pump appeared this problem ( A fan A pump, B induced draft fan B pump) , with the method of the oil pump motor reverse pump running normally. June 1 B induced draft fan switch B pump when the pump again appear this kind of problem, the same motor reversal, by making oil pump working properly. The 1 A # 2 boiler induced draft fan again appear this kind of problem, A pump station are serious quality hidden trouble, the oil pump itself exists defects, make oil pump self-priming ability drops, oil pump is not suppressed. 4 take precautions or lessons learned: ( 1) Operators in the oil pump station of the fan switch, it should start the standby pump running status to normal after the operation of the original oil pump when stopped. （ 2) Through the experiment to check the reliability of the standby pump. （ 3) Contact the factory technical personnel to the scene analysis and solve the problem. （ 4) At the right time to fan station to change the oil pump. ( 5) Research on power plant using the same equipment. 6, # 3 # 4 # 5 boiler induced draft fan station suggestion of imported gas station. （ Source: power E)
