摘要
水轮发电机组轴承油槽甩油是一种常见缺陷,为了解决此问题,往往采用改善油槽结构或密封方式等,但都不能彻底解决某些甩油现象。国内外文献中鲜有报道的吸油雾装置是中国水电基础局一种解决油雾现象的新型装置,它从油雾产生机理出发对油雾进行搜集,效果较好。通过对多种类型吸油雾装置的结构和原理研究,应用于某电站的吸油雾装置改造,取得了良好的效果。
Oil spill of the bearing oil groove is a common problem observed in hydro-turbine generator units.In order to solve this problem,measures such as improving the oil groove structure or the sealing modes are usually adopted.However,these measures cannot completely solve the oil spill problem.Oil mist absorption device is a novel facility to solve the oil spill problem,while it is seldom reported in literatures.Based on the oil mist generation mechanism,it can effectively collect the oil mist.Following the analysis of the structure and working mechanism of several types of the oil mist absorption devices,the successful application and renovation practice of the oil mist absorption device in a hydropower station are introduced.It provides useful reference for other hydropower stations to solve the oil spill problem.
