单级船闸运行可靠性分析及提升措施

为了提升单级船闸运行可靠性,对某单级船闸系统进行可靠性分析.通过对单级船闸进行系统功能结构分析,绘制可靠性框图,并建立运行可靠度模型,结合近年来船闸各设备的失效统计资料,计算得到某单级船闸各系统及设备的可靠度,并针对系统的薄弱环节提出相应的措施.结果表明,船闸人字门和启闭机的可靠性最高,电气控制系统的可靠性最低;传感器...

Operation reliability analysis and improvement measure of single-stage ship lock

In order to improve the operation reliability of single-stage ship lock,we carry out the reliability analysis of a single-stage ship lock system.Through the function structural analysis of the system and equipment,we draw the corresponding reliability block diagram,establish the operation reliability model,obtain the reliability of the single-stage ship lock system and equipment according to the failure statistics of each equipment in recent years,and propose the corresponding measure for the weak link of the system.The results show that the reliability of the miter gate and hoist of single-stage ship lock is the highest,and the reliability of the electrical control system is the lowest.The sensor and water stops are the weak links of the system.The system stability can be significantly improved by using redundant configuration,technology innovation,rapid maintenance,and other technologies.
