Description
技术领域
本发明属于化工材料生产技术领域,具体涉及一种合成溶水型油膜轴承油及其制备方法。
背景技术
轧机是钢铁厂“吃饭”的设备,是出效益的“高大上”的型材生产线。我国钢铁厂所用的轧机,绝大多数都依赖进口。轧机轴承一般采用油膜轴承,油膜轴承是一种径向滑动轴承,在轧制过程中,由于轧制力的作用,迫使辊轴轴颈发生移动,油膜轴承中心与轴颈的中心产生偏心,使油膜轴承与轴颈之间的间隙形成了两个区域,一个叫发散区(沿轴颈旋转方向间隙逐渐变大),另一个叫收敛区(沿轴颈旋转方向逐渐减小),所以必须使用油膜轴承油来保持其正常润滑。
实践中,由于油膜轴承设计的特殊性,使用过程中不可避免地会有水进入。目前,国际上的油膜轴承油采用的都是矿物油型的,矿油型油品进入0.3%的水分就会乳化,从而造成油品中的添加剂水解,导致油品的润滑和承载能力降低,金属腐蚀增大,油品输送困难,输送泵产生爆震、气蚀、气穴、工作寿命减短等一系列问题。
发明内容
为此,本发明提供一种合成溶水型油膜轴承油及其制备方法,解决油品中的添加剂水解,导致油品的润滑和承载能力降低,金属腐蚀增大,油品输送困难,输送泵产生爆震、气蚀、气穴、工作寿命减短等一系列问题。
