摘要:

摘要:小浪底水电站水轮机调速器筒阀液压系统运行中形成了大量油泥,导致控制阀组出现操作滞后和卡涩现象,影响机组的安全稳定运行。对油泥的成分及产生的原因进行了分析,通过对比两种形式的静电滤油机,选取了平衡电荷式滤油机对油泥进行在线过滤,使用效果良好,机组未再发生阀组卡涩现象。

Abstract:

Abstract:For the hydro turbine of Xiaolangdi Hydropower Station, a large amount of fatlute was formed in the operation of cylindrical valve hydraulic system of speed governor, which caused the phenomena of operation delay and jam of control valve group and influenced the safe and stable operation of unit. This paper analyzed the composition of fatlute and its causes, and selected equilibrium charge type oil filter for the online fatlute filtration by comparing two types of electrostatic oil filter, which had good using effect and the jam phenomenon of control valve group did not occur any more.
