VLCC软管吊机绞车故障分析

Failure analysis of VLCC hose crane winch

文章就某VLCC软管吊机在调试过程中,绞车只能一个方向旋转的现象,基于丹弗斯PVG32的多路阀控制回路,对绞车的各个相关控制阀组的工作原理及故障产生的原因进行分析,并提出了修理方案。

The article describes the phenomenon that the winch can only rotate in one direction during the commissioning process of a hose crane in a VLCC ship.Based on Danfoss PVG32 multi-way valve control circuit,the working principle and failure of each relevant control valve group of the winch.The reasons are analyzed and a repair plan is proposed.
