“复兴号”使用昆仑润滑齿轮箱油超过5000万公里

2019.04.24
          4月23日,中国石油润滑油公司在北京举办了“高铁自主研发第一油”——昆仑润滑齿轮箱润滑油护行高铁2周年的专题新闻发布会。

近年来,国内高速铁路事业飞速发展。为了实现高铁的中国自主制造,包括冶金、轴承、型材、润滑油在内的数十个行业,都开始了相关技术自主研发的攻坚。最初国内高铁的生产还需要引进国外技术,如今在大量自主研发技术的支持下,中国高铁已经进入了“中国标准时代”。

时速350公里的复兴号,是目前世界上运行速度最快的高铁列车。运行速度快、运营里程长和技术含量高,这都为国内的相关技术研发提出了很大的挑战。

其中,齿轮箱润滑油被称为高铁的血液,是高铁配套技术中技术含量最高的部分之一。

此前,国内齿轮箱润滑油一直由国外公司垄断。坚持攻关科研几十年后,昆仑润滑成功研发出高铁齿轮箱润滑油,率先通过60万公里实车测试的同时,也于2017年成功地将其应用在“复兴号”上。

这项完全由国内自主研发的产品,打破了国外品牌的垄断。

自2017年2月25日起到如今,昆仑润滑高铁齿轮箱油应用在“复兴号”动车组列车上已经满两年,单车安全平稳运行两个换油周期达到120万公里,护行总里程超过了5000万公里。

中国石油润滑油公司首席科学家伏喜胜介绍称,昆仑润滑油解决了高速轴承难以保持油膜强度的难题,完成了真正意义上的“自主研发的高铁世界第一油”的研发。中国石油研发的高铁齿轮箱油核心技术——“齿轮油极压抗磨、复合剂制备及工业化应用”,在2009年获得国家技术发明二等奖,这也是迄今为止中国润滑油领域唯一的一项国家技术发明奖。

从外面看,这所房子看起来非常优雅。它采用白色宝石建造,并配外汇交易员现在赚钱...有棕褐色石头装饰。大型三角形窗户可以让足够的光线进入房屋,并以非常对称的方式添加到房屋内。

这所房子配有现代化的厨房和一间小浴室,还有一个舒适的起居室,四间卧室,一个大餐厅,一个书房和一个宽敞的车库。

这座建筑的形状像一个方形的S.这两个延伸部分延伸到杂乱的木制悬垂板上,围绕着房子的一半。
二楼与第一层的大小相同,但其中一部分悬挂在地板下方的边缘,一外汇交易员现在赚钱...侧形成悬垂,另一侧形成阳台。这个楼层的风格与下面的楼层大致相同。

屋顶低而方形,并覆盖着圆形屋顶瓦片。两个大烟囱坐在房子的两边。几个长而薄的窗户让屋顶下方的房间充足光线。
这座房子周围环绕着精心打理的花园。草,花片和树木都以时尚的方式摆放。外汇交易员现在赚钱...
