在正常使用过程中化工结构的预防性维修 ,主要目的是保证结构在预定时间内能完成其设计使用功能 .当后续使用时间已知时 ,预防性维修的关键是维修可靠度水平的确定 .采用化工结构基于后续使用时间的维修可靠度水平优化决策的工程实用方法 ,对规划受腐蚀结构在正常使用过程中的维护对策具有一定的理论指导意义
The main purpose of the preventive maintenance of the chemical structure during normal use is to ensure that the structure can complete its designed and used functions within a predetermined time.When the time of continued use is known, the key of preventive maintenance is the determination of the reliability level of maintenance. Chemical Engineering Based on the use of time after the reliability of the maintenance level of reliability optimization of practical engineering decision-making, planning by the corrosive structure in the normal use of the maintenance strategy has some theoretical significance
