某新型拖船拖曳绞车损坏原因分析及解决方案

Reason Analysis and Solution for Drag Winch of New TUG

本文首先介绍了某新型拖船拖曳绞车操作故障情况;分析了设备液压系统的工作原理,并解释了液压马达损坏的具体原因;最后提出拖船在放缆过程中要低速航行,且不可随意切换速度模式;另外应在马达AB口增加压差传感器和报警,提醒用户设备情况。

This article introduces the operation situation of a new towing winch on a tugboat first.Then it analyses the working theory of the hydraulic system,and explains the detailed reason of hydraulic motor failure.At last it suggests that the tugboat should sail slowly when it is rolling cable,and should not switch the speed mode casually.In addition,a differential pressure transducer between opening A and B of hydraulic motor should be set to warn the equipment situation for the user.
