导致除氧器低水位的可能原因有：除氧器的进水量太小或除氧器的水位主动调理失灵；凝聚水、给水管道走漏，除氧器放水阀误开或走漏；凝聚水泵作业反常或凝聚水再循环阀误开；机组升负荷过快或除氧器水位调理滞后。在承认除氧器低水位后，应检查凝聚水泵是否正常，凝聚水、给水管道是否存在走漏，除氧器放水阀是否误开等。在凝聚水泵反常时，应切换至备用泵运转；若凝聚水再循环阀误开则应封闭，操控机组的升负荷速率，必要时增开一台凝聚水泵。在除氧器呈现低水位报警时，敞开除氧器水位调理阀的旁路阀，调理给水流量，但应留意锅炉的汽包水位，必要时机组适量减小一些负荷，除氧器呈现低一低水位报警时，主动封闭除氧器的进汽阀，给水泵跳闸。
the possible reasons for the low water level of the deaerator are: the water intake of the deaerator is too small or the water level of the deaerator is out of order; the condensed water, the water supply pipeline leak, the deaerator discharge valve open or leak; the condensing pump operation is abnormal or the condensed water recirculation valve is mistaken; the unit load is too fast or the deaerator water level conditioning lags behind. after acknowledging the low water level of the deaerator, check whether the condensate pump is normal, whether there is leakage in the condensate and water supply pipe, whether the deaerator discharge valve is mistakenly opened or not. when the condensing pump is abnormal, it should switch to the standby pump operation. if the condensate recirculation valve is mistaken, it should be closed, control the load raising rate of the unit, and add a condensed water pump when necessary. when the deaerator presents a low water level alarm, open the bypass valve of the deaerator water level regulating valve to regulate the flow rate of water supply, but should pay attention to the boiler drum water level. when necessary, a certain amount of load is reduced by the unit. when the deaerator presents a low water level alarm, the intake valve of the deaerator is actively closed and the water supply pump tripping.
(3)造成除氧器振荡和汽水管道冲击的原因可能是：水侧过负荷，疏水不妥，喷嘴淋水盘箱损坏等。应根据不同原因采取有用办法消除振荡。汽水管道发生冲击现象时，应立即中止供汽、供水，充沛暖管、疏水后再操作；若因除氧器水位高而向汽水管道倒水，应立即放水下降除氧器水位，而且敞开有关汽水管道上的疏水阀门。
(3) the cause of the oscillation of the deaerator and the impact of the steam water pipe may be: overloading on the water side, improper drainage, and damage to the spray box. effective measures should be taken to eliminate oscillation based on different reasons. when the steam water pipe is impacted, the steam supply and water supply should be stopped immediately. the water pipe should be fully heated and then operated again. if the water level of the deaerator is high and the water pipe is inverted, the water level of the deaerator should be dropped immediately and the hydrophobic valve on the steam water pipe should be open.
3．除氧器压力及水位维护
3. deaerator pressure and water level maintenance
(1)压力维护。当除氧器压力低于0.15mpa时，联动封闭四段抽汽至除氧器电动阻隔门，联动敞开备用汽源电动门，备用汽源投入（高加投运前切为四段抽汽）；当除氧器压力高于0. 18mpa时，联动封闭备用汽源电动门，联动敞开四段抽汽至除氧器电动阻隔门。
(1) pressure maintenance. when the deaerator pressure is lower than 0.15mpa, the linkage between four segments is closed to the electric barrier gate of the deaerator, and the standby steam source is open and the standby steam source is cut into four sections before the operation. when the deaerator pressure is higher than 0. 18mpa, the linkage is closed to the electric door of the spare steam source, and the linkage opens four segments to the deaerator. electric barrier door.
(2)高水位维护。当除氧器水位高i值，报警，联关除氧器上水调理门；当除氧器水位抵达高ⅱ值时，联动敞开除氧器事端放水阀；当除氧器水位抵达高ⅲ值时，除氧器主动阻隔，联动封闭四抽至除氧器进汽电动门和逆止门，3号高加至除氧器正常疏水阀联动封闭，联开3号高加至凝汽器疏水阀。
(2) high water level maintenance. when the water level of the deaerator is high i, the water level of the deaerator is raised. when the water level of the deaerator reaches high level, the deaerator is open to the deaerator. when the water level of the deaerator reaches the high level of grade iii, the deaerator is actively obstructing, and the linkage is closed four to the deaerator&＃39;s electric door and the reverse gate, and no. 3 is elevated to the deaerator normal. steam trap linkage closed, linked to no. 3 plus to condenser trap.
