浅谈应用环保润滑油情况下的尾管轴承高温现象

摘要

VGP 2013 enforced by EPA unilaterally requests that all the commercial vessels more than 79 feet in length operating in US waters have to use EALs in all oil-to-sea interfaces of the ship“unless technically infeasible”. Many shipyards in China, some others in Japan and Korea, were faced with S/T high-temperature alarm risk after using EALs, which cause a lot of discussion about EALs. Based on some survey reports for EALs, this paper classiifes the feedback data and summaries several factors that possibly cause S/T high-temperature alarm, which are analyzed one by one. Finally some suggestions are given out to avoid S/T high-temperature alarm for industrial reference.% 美国环保署VGP 2013单方面强制生效，要求所有进入美国水域的船舶在其油水界面使用环保润滑油（除非技术上不可行）。国内诸多船厂包括日韩船厂在使用环保润滑油以后，多次发生尾管高温报警，由此引发了行业对于环保润滑油的思考。文章结合环保润滑油的调查反馈报告，对反馈数据进行分类统计，在此基础上梳理出若干种可能造成尾管高温的因素并进行逐一剖析，最后有针对性地提出一系列实施建议，供业界参考。
