摘要
为分析主机拉缸的原因,经实船勘验分析,通过曲轴拐档差的测量、吊缸检查和对气缸的润滑系统、十字头与导板间的间隙测量等工序后,得出导板与滑块中心线失中是导致该主机拉缸的直接原因.为此在实施修理过程中制订了正确合理的修理方案,从而解决了拉缸问题.
The main engine with long ship age is prone to cylinder failure.To this,the cause of cylinder pulling should be made clear first,the crankshaft crank offset measurement,hanging cylinder inspection and lubrication system of the cylinder,cross head and guide plate clearance measurement and cylinder inspection;After the inspection,inspection and measurement of the main engine parts,a reasonable and correct repair scheme is obtained,thus solving the problem of cylinder drawing.
