凉水塔带水更换填料改善汽机真空

Without cutting off the water supply to repleace the stuffing material of cooling tower to improve the steam turbine vacuum condition

汽轮机真空下降,分析与凉水塔冷却水平下降有关,利用大修机会,在不停水的情况下作业施工,更换凉水塔填料。另外通过清理凉水塔水槽,更换损坏喷头,清洗凝汽器等多项措施改善了汽轮机的真空状况。对不停水施工有一定的参考意义。

Analyses the reason of turbines vacuum decline and the reduction of the cooling tower,and point out the measures to replace the cooling tower of fill material particular construction without cutting off the water supply.In addition,through the clearing cooling tower,replacement of the damaged nozzle,cleaning the condenser etc.to improve the steam turbine vacuum condition.
