摘要
大型水泵机组的维修性直接影响维修时间、维修质量和维修费用.确定了水泵机组维修性的五要素:维修对象,规定条件,规定程序和方法,规定时间,规定功能;明确了开展水泵机组维修性研究的必要性.调查了大型水泵机组的常见故障,分析了水泵机组维修性的影响因素,比较了不同结构形式水泵机组维修性特点,提出了提高水泵机组维修性的措施.结果表明:电机推力瓦烧损、水泵导轴承失效和水泵汽蚀是大型水泵机组的主要故障形式和具体维修对象;立式半井筒式机组具有较好的维修性.
The maintainability of large pump unit influences the maintenance time, maintenance expense, and maintenance quality directly. The five factors of pump unit maintainability are determined： maintenance objects, given conditions, given processes and means, given time, and given function. The common breakdowns of large pump units are investigated. The influencing factors on maintainability of water pump units are analyzed. The maintenance characteristics of pump units of different structures are. compared Measures are put forward to improve the maintainability of pump units. The results show that the burnout of thrust bearing liner of motors, failure of guide bearing and the pump cavitations are the main breakdowns of large pump units, and the vertical half-well casing pump has a better maintainability.
