针对当前电厂汽动给水泵高低压汽源自动切换的难题,如何实现从小机低压汽源自动切到高压汽源,保证锅炉给水的稳定。通过试验和控制思路修改来实现,以便降低机组的事故和非停的发生。因此进行了大量理论和实际的探索。
針對噹前電廠汽動給水泵高低壓汽源自動切換的難題,如何實現從小機低壓汽源自動切到高壓汽源,保證鍋爐給水的穩定。通過試驗和控製思路脩改來實現,以便降低機組的事故和非停的髮生。因此進行瞭大量理論和實際的探索。

Aiming at the existing problem of the automatic switching of the high and low pressure steam source for the power plant steam turbine feed water pump. How to achieve the small steam turbine switch to the high-pressure steam source automatically as the low-pressure steam source is lost, so as to ensure the stability of the boiler feed water supply. Throughtesting and change of control ideas, the occurrence of accidents and non-stop could be reduced. Therefore, the authors have made a lot of theoretical and practical exploration.
