Constant pressure operation under the set pressure ,The heating steam of Assistance enters the deaerator through the motor operated adjust valve. According to the internal set pressure (0.147Mpa.a) of the deaerator, it will automatically adjust the valve opening to control the flow of the inlet heating steam.3、高压除氧器采用双封头卧式结构，通过支座坐落在水箱筒体上，水箱采用双封头卧式结构，除氧器及水箱通过下水管和蒸汽连通管进行连通，维持除氧器和水箱压力平衡，保证设备安全稳定运行。
3). The high pressure deaerator adopts double-head horizontal construction , Pass to pay to install in the storage tank tube body top, The storage tank adopts double-head horizontal structure.connecting with storage tank cylinder by the downcomer and steam connecting pipe, Maintain the pressure balance about the deaerator and the storage tank, Promise an equipmentsa safety and stabilize to circulate.4、高压除氧器设有（A48Y-16C）型弹簧全启式安全阀作为泻放装置，安全阀的开启压力和数量见设备图纸。
4). The high pressure deaerating equipment is equipped with (A48Y-16C) spring full opening safety valve as pressure relief device. For the opening pressure of safety valve and number , please refer to the equipment drawing.5、在水箱筒体上设有2对就地磁翻板水位计，用于现场观察，还根据需要设有3对平衡容器，用于远方水位显示及报警、控制水位，当水位高于预定值时，及时发出高水位溢流放水信号，自动开启气动调节阀进行排水，以维持水箱中的正常水位，保证设备稳定运行。
另设2对备用水位测量接口，便于用户根据需要设置水位控制仪表。
5). There is two group local magnetic conversion water level gauge equipped on the storage tank cylinder for local observation. According to requirement, it is also equipped with three group of balance vesse for remote water level indication and alarm. When water level is higher than the predefined value, it will give emergency drain signal and automatically open the air control regulates valve. It is equipped with two group of balance vessel to provide water level automaticadjust valve with water level signal to control the water level of the storage tank and for remote indication or as a standby.二、结构及原理2. Construction and Function1、高压除氧器按水流方向，由上而下，分为排汽区段，空间区（除氧区）和填料区段。
主凝结水及补给水，以及各处合格的疏水进入除氧器水室内，在压差的作用下，经多只弹簧喷嘴，在压差的作用下形成射流喷射，形成伞状的水膜裙，加热蒸汽由淋水盘填料层侧面进入，在淋水盘间折流穿行，与入口水逐级相遇，进行热质交换。
将入口水加热到与除氧器运行压力相对应的饱和蒸汽温度，溶解于水中的氧气及不凝结气体，自水中逸出，经除氧器（头）上部的汽水分离装置和排汽管汇集管，排入大气，排氧门可以根据出水含氧量指标的变化，及时进行调整开度，以保证在出水含氧量达标的情况下节能。
入口水在空间区内完成一次除氧，在淋水盘层完成二次除氧。
除氧水由除氧器自流而下，经下水管自由下落，汇集于除氧水箱内。
除氧器端部还设有高加疏水管，为减少高加疏水对除氧器内件的冲击，设有不锈钢挡板，对进入的高加疏水进行汽水分离。
这种除氧器的传热系数较高，可在较短的时间内将水加热到要求的状态，达到除氧效果。
1). According to the flowing direction of the water, from top to bottom, the high pressure deaerator is divided into steam venting section, spray device (consisting of water inlet pipe assembly and nozzle), space section and packing section. The main condensed water, feedwater make-up and all other qualified drains enter the spray device of the deaerator. Under the effect of pressure difference, the rotational water spray down like the shape of membrane from the Several spring coils spray a mouth. Heat steam from pour the water dish filler layer on the side into, at pour the water dish fold to flow to wear a line. The primary heating steam rises from the bottom of the packing, passing through the packing and the water distribution spacers, it passes through the hollow part and outside surface of the water skirt inside, and gradually meets the inlet water to perform heat exchange. When the inlet water is heated to the saturation steam temperature corresponding to the operation pressure of the deaerator, the oxygen and other uncondensable gases dissolved in the water will be isolated from the water and vented to the atmosphere through the vent pipe of the steam/water separator at the top of the deaerator. The inlet water implements the first deoxygenation in the spray atomization section and finishes the second deoxygenation in the packing. The deoxygenated water flows down in the deaerator, passing through the water distribution pipe of the storage tank, It is collected in the storage tank. Establish H.P. heater drain inlet at the end of deaerator , For reduce H.P. heater drain inlet to in addition to the impact of the piece inside the oxygen machine, Establish the stainless steel blocks plank, H.P. heater drain inlet to carry on separation towards enter of highly.The heat transfer coefficient of this kind of deaerator is high; it can heat the water to satisfy the requirements in short time and reach the deoxygenation and heating effect.2、除氧水箱由卧式筒体和两个封头焊制而成，水箱两端设有两个供检修和维护用的人孔。
