船用折叠式舱口盖液压系统故障树分析

Fault Tree Analysis of Hydraulic System of Marine Folding Hatch Cover

折叠式舱口盖是散货船的重要组成部分,而用于驱动舱口盖的液压系统非常容易出现故障,所以为了保证船用折叠式舱口盖平稳运行,在安装调试阶段运用故障树分析法对舱口盖的液压系统进行故障分析。首先运用故障树分析法对影响液压系统的因素进行定量分析,然后计算出各个故障的最小割集的故障模式概率,为船用折叠式舱口盖液压系统的故障排除、乃至设计和调试提供一定参考。

Folding hatch cover is one of the important components of bulk carrier, and the hydraulic system used to drive the hatch cover is very prone to failure, in order to ensure the smooth operation of marine folding hatch cover, using fault tree analysis to analyze the fault of the hydraulic system of the hatch cover during the installation and debugging phase. Firstly, the factors affecting hydraulic system are analyzed quantitatively by fault tree analysis method, and then calculate the fault mode probability of the minimum cut set of each fault, which provides a reference for the fault elimination, design and commission of marine folding hatch cover hydraulic system.
