6230广州柴油机技术资料

8320ZCd-6 柴油机咬缸事故分析及反思韩锡方李启富许昌明一、事故发生经过某轮是一艘新船，配备广州柴油机厂生产的6320ZCd-6柴油机，额定功率2060kw，额定转速525r/mim，今年1月31 日首航，固定航线天津至广东汕头，该轮第9 航次，于2006年5月1日15、00 时开航，由天津装煤炭驶往汕头。

2006年5月5日03:30 时左右船舶航行到大陈岛以东大约10 海里(北纬28、29、东经122、05)处时，发生主机第四缸活塞咬缸事故，据轮机日志记录，发生事故前主机运转一直都很正常。

据当班人员反映，03、30 时左右从机舱平台甲板集控室出来准备进行巡回检查时，发现主机周围烟雾弥漫，气味刺鼻，立即到机旁将主机紧急停车，随后打开曲轴箱导门检查，发现主机第四缸缸套漏水，吊缸检查，发现该缸发生严重的咬缸事故。

由于船上配件不足、配件尺寸不符(如厂供连杆小端铜套与活塞销配合过盈且过盈值达到1、1mm；船上没有配备活塞销、活塞和连杆；市购的活塞销比本机原活塞销长2mm，且油道不符；市购的活塞加工不规范，裙部外径比说明书标准大0、14mm 左右，厂供缸套上端有一道50mm～60mm 宽、内径￠320-0、20 的耐磨圈(说明书没有标明)，两者形成过盈配合；而市购的缸套没有这一圈；与市购的活塞可配合使用等)及其他原因，船舶自修了几天无法修复，根据公司指令，5 月8 日封缸将船驶往温岭石塘抛锚，公司机务人员及厂方人员共同到船协助修理。

二、现场勘验和检查该机第四缸发生事故，其余各缸均正常，损坏情况如下：1、气缸套内表面发黑，有严重的纵向拉痕，外表面封水橡胶圈轻度硬化，弹性不足；2、活塞外表面发黑，活塞环咬死在环槽内，外园与活塞外表面磨得一样平；3、活塞销孔发黑、咬毛；4、连杆小端铜套抱死在活塞销上，定位销磨断；5、连杆小端铜套座孔天地之间比左右之间大0、1mm，拉长变形；6、连杆大端轴承正常，无明显损坏现象；根据现场勘验情况，估计引起咬缸事故的最大可能是该缸断油或供油不足所至，因此对该缸的润滑油路进行了祥细的检查，当拆下该缸主油路油管时，发现有一棵螺钉在油管里，堵塞了主油路，仔细观察该螺钉，确定是半自清滤器芯子的紧固螺钉，拆卸所有4 只半自清滤器芯子检查，发现其中一只滤芯果然少了一棵螺钉。
