【Abstract】 The delivery capacity of the wax-oil pump is not sufficient as the pump on duty is switched off to reserved pump,having an influnce on continuous operation in hydrogenation unit.Based on the operator,medium,pipeline and the pump itself,using the analysis of Fault Tree,the analytical tree of cause of the unsufficient delivery was set up.The factors of unsufficient delivery were presented.更多还原
