针对水电机组润滑系统中，常采用涡轮机油作为润滑、冷却介质的情况，将专门研发的石墨烯添加剂按一定比例加入水电机组润滑系统的涡轮机油中，通过现场试验研究其对润滑性能的影响。根据机组轴承瓦温监测数据，对比加入添加剂前后温度变化情况，间接反映石墨烯添加剂对水电机组润滑系统性能的影响。结果表明：所加入的石墨烯添加剂能改善涡轮机油减摩抗磨性能，为轴承润滑性能改善及轴瓦保护提供新思路。

The turbine oil is often used as the lubrication and cooling medium in the lubrication system of hydropower units,Sographene additives specially developed are added to it in a certain proportion,and its influence on lubrication performance is studied through onsite tests.According to the temperature monitoring data of the bearing bush of the unit,the temperature change before and after adding the additive is compared,which indirectly reflects the influence of the graphene additive on the performance of the lubrication system of the hydropower unit.The results show that the added graphene additives can improve the antifriction and antiwear performance of turbine oil,and provide new ideas to improve the bearing lubrication performance and bearing protection.
