破乳化度是油品的重要理化指标.由于汽轮机结构的原因,机组实际运行中,机油破乳化时间超标是普遍存在的问题,其原因一是汽轮机轴封存在间隙,从中漏出的水蒸汽很容易浸入工作油中;二是机油处于不停地循环、搅拌、掺和的工况,容易超过油一水界面张力而形成油水乳状液;三是油系统存在活性物质.以上因素形成了汽轮机在运行中机油破乳化时间超标的条件.因此,许多电站对汽轮机油常常采用沉
The degree of demulsification is an important physical and chemical index of oil products.Because of the structure of steam turbine, during the actual operation of the unit, it is a ubiquitous problem that the timing of oil emulsion demulsification exceeds the standard. The reason is that steam turbine shaft seal is in the gap and the water vapor leaking therefrom is very easy Immersed in working oil; Second, the oil is kept in circulation, mixing, mixing conditions, easy to exceed oil-water interfacial tension and the formation of oil-water emulsion; Third, the existence of active oil system. These factors form the turbine running In the case of excessive oil emulsion breaking time.Therefore, many power plants often use turbine oil
