耙吸式挖泥船液压系统故障逻辑分析诊断

Logical analysis and diagnosis of the hydraulic system trouble for the drag-suction dredger

简述耙吸式挖泥船液压系统结构及工作机理,以实船为例,介绍故障分析与诊断思路,采用功能跟踪筛检法和假设-验证分析法分析诊断其液压系统故障分析,收效良好。

In light of the structure and working principle of the hydraulic system in the drag-suction dredger. This paper introduces the idea of trouble analysis and diagnosis, and applies the method of function tracking and assumption-verification to the trouble diagnosis of the hydraulic system of a real drag- suction dredger.
