发电机密封油氢侧供油单元技术改造

Technical Reform of Hydrogen Side Oil Supply Unit of Generator Sealed Oil

某电厂汽轮发电机组氢气纯度下降快,需通过频繁排换补氢的方式维持氢气纯度,对双流环密封油系统氢侧供油单元进行技术改造,在实际运行中对提高发电机氢气纯度效果明显,为汽轮发电机组的安全、经济运行提供了可靠的保障。

The hydrogen purity of a turbo generator in a power plant decreases rapidly, and the hydrogen purity needs to be maintained by frequent replacement of hydrogen.Technological transformation of hydrogen side oil supply unit in double flow ring seal oil system is carried out.The effect of improving the purity of generator hydrogen in the actual operation is obvious.The technical reform provides a reliable guarantee for the safety and economic operation of the turbo generator set.
