某双机双桨客滚船曲轴轴瓦烧蚀事故分析与预防

Analysis and Prevention of the Crankshaft Bearing Shell Ablation Occurred on a Ro/Ro Passenger Vessel

某双机双桨客滚船在试航过程中,由于主机滑油系统调压阀故障,造成主机在110%负荷试验时由于滑油供油量不足导致曲轴轴瓦严重烧蚀.现对事故原因给予分析,阐述机损维修过程,对避免此类事故的发生给出建议.

In the trial process of a double-engine twin-screw Ro/Ro passenger vessel, a serious ablation of crankshaft bearing shell occurred in the 110% load test because of lubricant oil supply shortage. The paper analyses the cause of the fault, elaborates the process engine occurrence of such accidents. damage repair, and gives some suggestions to avoid the
