如何进行双室浮动床的操作控制
如何进行双室浮动床的操作控制？
双室浮动床的操作控制如图3-3-25所示。
其操作控制步骤简述如下。
（1）成床开出水阀，再开进水阀，控制流速30～50m/h，约2min 左右即可成床，此时因水质不稳定要先行排放，经3～5min后，取样分析，当阳床出水硬度为0、钠离子小于200μg/L、酸度小于10mmol/L，阴床出水电导率小于10μS/cm、硅根小于100μg/L时，即
为合格水进入水箱，直至失效。
（2）落床树脂经过离子交换失效之后，进行再生前的落床操作。
落床有压力落床、放压落床及重力落床等方法。
为使树脂不乱层和树脂表面分布均匀，以采用重力落床为好。
重力落床只需要关闭出水阀和进水阀。
树脂藉其重力自动落床，时间约3～4min。
（3）再生、置换、正洗先配好2%左右浓度的再生液，打开排水阀和进再生液阀。
控制流速3～6m/h，时间约30～40min。
然后关再生液阀，维持原来流速置换至再生液完全排出，约15～30min再转入
正洗：将流速提高至10～20m/h，正洗终点控制至出水达到合格水为止。
（4）反洗阳床经过20周期左右，阴床经过60周期左右的运行后，为了清洗树脂中的悬浮物或微生物以及漂洗细碎树脂，可分别将树脂压入清洗塔进行反洗，流速约10m/h。
为了提高清洗效果，可以通以29.4kPa压缩空气（要除油）进行擦洗，直至排出水从锈黄色变为清澈为止。
然后再压入交换器中进行再生操作。

HOW THE PRODUCT WORKS.............................................................................................2 2. INSTALLATION......................................................................................................................2 3. START UP...............................................................................................................................4 4. MAINTENANCE PROCEDURES...........................................................................................7 5.TECHNICAL DATA.................................................................................................................8 6.SUPPLIER ADDRESS (9)1. How the Product works1.1. IntroductionThe objective of the product is to relieve the pressure created under a patient when lying on a bed so that blood flow is maintained and tissue oxygenation achieved. It does this by intermittently removing the pressure from the patient by sequentially deflating the supporting air cells of the mattress. The Power Unit provides the source of energy to achieve this and also the necessary monitoring and control systems for efficient and safe operation.In simple terms the air compressor delivers air to the solenoid valves controlling the flow of air into and out of the mattress air cells. The pressure of the air within the mattress is continuously monitored by the solid-state pressure sensor enabling the inflation pressure to be directly controlled and varied to achieve the desired comfort level.The software based control system operates the solenoid valves to enable air to flow into, or out of, the air cells as required according to the operating mode selected. It also maintains the air pressure within the air cells at the required level and controls the action of the alarm system in the event of mains supply failure or over or under inflation pressures occurring.2. Installation2.1. Installation of the MattressRemove the hospital mattress and make sure that the slatted base frame is free of pointed or sharp objects to avoid damaging the Mattress.Place the Air Sure Mattress on the bed. Ensure that the removable cover is on top and that the umbilical hose is at the foot end of the bed. Fasten the Mattress to the bed frame using the straps on the base of the Mattress. The straps should not be too tight and should not interfere with the operation of the bed. They should be checked regularly.Cover the Mattress with a loose fitting sheet.2.2. Installation of the Power UnitHang the Power Unit onto the footboard. The mounting hooks swivel to suit the thickness of the footboard or rail.The hooks also adjust vertically with click-stop locations at 20mm intervals. The Power Unit should be supported until the correct position has been achieved and the black clamping screws firmly tightened (for convenience the clamping screw orientation can be changed by depressing the orange button and freely rotating the clamp screw arms to an optimum position)Umbilical2.3. ConnectingtheConnect the Umbilical hose to the Power Unit by inserting the 4 male probes into the female quick-connect valves.The end probe is inserted into the top valve and the other three probes are then aligned with their corresponding valves. The Head Cell/Former supply probe is physically non-interchangeable with the other 3 probes to prevent cross coupling. When they are correctly connected an audible ‘click’ will be heard.ISSUE 1 PAGE 2 OF 9ISSUE 1PAGE 3OF 92.4. Electrical Supply cableRemove the mains cable from its storage housing in the base of the Power Unit by rotating the two retaining arms so that the cable is no longer restrained and plug into a suitable 230v mains socket. Any surplus cable can be rewound and stored within the Power Unit.2.5. Switch OnSwitch on the Power Unit using the mains on/off switch. The message ‘Please Wait – Setting Pressure’ appears on the display and remains until the Mattress is fully inflated. The green ‘Ready’ LED is illuminated showing that the System is now available for use.ISSUE 1PAGE 4OF 93. Start UpWhen the Power Unit is switched on the display shows the message ‘Please wait – Adjusting Pressure’. The Pressure Sensor monitors the pressure in the Former/Head Cell supply line and when the inflation pressure reaches 50mmHg the system is switched into its operating mode and the green ‘Ready’ LED is illuminated.3.1. Dynamic ModeThis mode of operation and the ‘Firm’ comfort setting are automatically selected at the end of the initial inflation phase. The Display message shown is ‘Dynamic – Comfort: Firm’.3.2. Static ModeThis mode is selected by pressing the Mode switch on the membrane panel. The Display message shown is: Static – Comfort: Firm (or other setting selected, see 3.1.5). The Mode is automatically limited to a maximum time of 2 hours, after which, for reasons of clinical safety, the System switches into the Dynamic Mode.3.3. Comfort SettingsThe air pressure within the Cells can be varied to provide varying degrees of comfort to suit patient or clinical needs. Three settings; Firm, Medium and Soft are provided equating to nominal inflation pressures of 50,40 and 30mmHg. Pressing the ‘Comfort’ switch cycles the System through the three settings in turn. The setting selected is displayed on the message panel e.g. Comfort: Medium.If the setting selected equates to a higher pressure than that already in the Cells the System switches into the inflation phase until the pressure selected is reached. If the existing pressure is too high the System switches into the deflation phase until the required pressure reduction is achieved. The Comfort setting is independent of the Dynamic and Static settings3.4. Maximum InflationThis is a variant of the Static mode in which the Cell pressure is increased to a nominal value of 60mmHg(65mmHg in High Pressure option) in order to provide a rigid, stable surface when physiotherapy and other nursing procedures are being carried out.This mode is limited to a maximum of 20 minutes although it can be extended for a further 20 minutes by pressing the Maximum Inflation switch at any point during this period. The initial display message reads: Max. Pressure – 20 min. Remain. The time counts down 20, 19, 18, etc, until at the end of 20 minutes the System automaticallyISSUE 1PAGE 5 OF 9switches to Dynamic cycling at the previously selected Comfort setting. The Maximum Inflation mode can also be ended, at any time, by pressing the Mode switch.3.5. DeflationIn this mode, selected by pressing the Alarm Cancel and Deflate switches simultaneously, the Cells are emptied of air. The initial display message reads: Deflate – 20mins Remain. The time counts down 20, 19, 18, etc, until at theend of 20 minutes the System automatically switches off, the Valves are de-energised and the Compressor ceases to run. The display message changes to: Deflate Complete.3.6. Head Cell DeflationThe Head Cells normally remain constantly inflated (together with the Formers) at the pressure selected by the Comfort switch.Clinically it may be necessary to nurse patients in a prone position i.e. face down. To facilitate this it is desirable to deflate the Head Cells to create a void in front of the patient’s face. This is achieved by reversing the settings of the two On/Off taps fitted in the Head Cell tubing circuit. Access is gained via a small zip located at the left hand side of the head end.To deflate the Head Cell first close the on/off tap fitted to the supply tube, which runs along the side of the mattress. This isolates the Head Cells from the Formers. Then open the on/off tap at the free end of the tubing (situated at the end of the mattress). This opens the Head Cells to the atmosphere and the Cells deflate.Note: The Formers must remain inflated at the Comfort setting selected as they now act as the sole reservoirmonitored by the System’s pressure sensor. If the pressure in the Formers is allowed to fall significantly as a result of opening the on/ff taps in the wrong sequence the ‘Low Pressure’ Alarm would be activated. To re-inflate the Head Cells, first close the end on/off tap and then open the supply line tap.ISSUE 1PAGE 6OF 93.7. CPR DeflationThe CPR Valve consists of a manually operated rotary action Valve incorporating 4 individual, large bore, spring loaded, dump valves which, when opened, connect all the Cells and Formers to atmosphere achieving rapid Mattress deflation. For convenience and accessibility the Valve is mounted in the umbilical between the Mattress and Power Unit.Turning the red operating knob clockwise to the ‘CPR’ position activates the Valve. As the Mattress deflates the ‘Low Pressure’ alarm will be activated and should be cancelled by pressing the ‘Alarm Reset’ button and switching the Power Unit off.Warning: Close the CPR Valve by rotating the red knob anti-clockwise to the ‘Normal’ position before switching the Power Unit on again.3.8. TransportationTo change the location of the bed, switch the system to ‘Static’ and allow all the cells to fully inflate. Switch off the Power Unit using the on/off switch and disconnect the electrical supply cable from the mains socket. The bed can now be moved to a new location where it must immediately be reconnected to the mains electrical supply and the system switched back on. Once the mattress has been refilled, the system will automatically switch into the ‘Dynamic’ mode at the ‘Firm’ comfort setting. Other settings may then be selected as required.To move the patient and mattress, e.g. by trolley, switch the system to ‘Static’ and allow all the cells to fully inflate. Then switch off the Power Unit and disconnect the umbilical hose by depressing the metal actuator buttons on the four quick-connect valves at the side of the Power Unit and withdrawing the probes. The mattress can now be moved independently and will remain inflated for several hours. It should be reconnected with the power unit and mains electrical supply as soon as practicable.Warning: The mattress will not ‘alternate’ when disconnected from the power unit and/or the mains electrical supply and hence not provide optimal pressure relief.4.

二、工作原理及主要结构
1、工作原理：双室床主要是利用弱酸或弱碱树脂的工作交换容量高，再生比耗低和抗有机物污染性能好的特点。
工作时，弱酸树脂能与原水中的Ca(HCO3)
2、Mg(HCO3)2起作用，将其转换成H2CO3。
而弱碱性树脂，主要是与水中的强酸阴离子起作用，这样可使交换容量低的强碱树脂主要用来置换水中少量的SiO2和少量的游离碳酸，提高了强碱性树脂的交换容量和出水品质。
原水经阳、阴双室床处理后水质变化情况如下：
2、主要结构
（1）双室床分上下两室，上室装弱型树脂，下室装强型树脂。
（2）进水装置：为母、支管形式。
母、支管的材料均为1Cr18Ni9Ti。
（3）中间疏水装置：为带双头水帽的多孔板，水帽结构新颖。
（4）出水装置：为钢衬胶穹形多孔板上装不同级配的石英砂垫层。
石英砂垫层级配表:
（5）外部管系：主要阀门采用正面二列布置，出厂设备配手动衬胶隔膜阀，也可按用户要求配气动隔膜阀。
（6）设备装设上、下人孔各一个，以利于安装和检修。
（7）为观察树脂运行工况，在设备正同左侧120度和135度处两室均设置上、下窥视镜。
（8）进、出口压力及取样装置接管，由法兰中所夹塑料环引出，接管材料为不锈钢。
（9）设备内衬橡胶防腐。
（10）设备器底为三个支脚，封头顶上固定有二对吊攀。
三、设备操作及运行
1、投运前的准备工作
（1）石英砂的预处理：一般要求选用优质的白石英砂（含SiO2为
99%以上），按石英砂级配表的要求填入交换器内，选用10～15%HC1浸泡12～24小时后，然后排去酸液再用清水清洗好，再将水排空，准备碱处理，用10～15%的NaOH溶液浸泡12～24小时，然后排去碱液再用清水清洗好石英砂。
（2）离子交换树脂的预处理
在工业产品的树脂中，常含有一些过剩溶剂及反应不完全而生成的低聚物和某些重金属离子。
如在使用前不除去这些物质，就可能在使用初期污染出水质量。
树脂处理后，可以提高其稳定性。
有的树脂产品质量好，可不进行预处理。
预处理工作一般在交换器内进行。
预处理的程序如下：

（3）操作步骤及工艺参数
①运行
1）运行流速：一般为25m/h，最大流速为40m/h。
2）出水质量标准：双室床正常运行时，应定期检验阴双室床出水的电导率、SiO2含量。
当阳双室床出水含Na+量超过500微克/升，或当阴双室床出水电导率超过10μs/cm，SiO2含量超过100微克/升时，即显示离子交换树脂已失效，此时即应停止运行，进行树脂再生处理。
②再生：再生的目的是为了恢复离子交换树脂的交换能力
1）再生剂的选择：为了防止硫酸钙在弱酸树脂层析出，阳离子交换树脂的再生剂应选用盐酸，而不宜选用硫酸，阴离子交换剂的再生剂选用氢氧化钠。
2）再生流速与再生时间：阳双室床的再生流速一般为3～5m/h，再生时间应不小于60分钟，阴双室床的再生流速为3～5m/h，再生时间一般不小于60分钟。
阴双室床再生前应先预热进水30分钟，温度40℃，然后再进加温至40±1℃的NaOH再生液。
阳阴双室床再生、置换用水均为除盐水。
3）再生操作
a、进再生液：开启空气门、再生液门和再生排水门，以调整浓度和流速，再生初期强型树脂层稍有扰动，弱型树脂一直处于悬浮状态。
b、置换（逆冲洗）
置换是再生过程的继续，是再生后正洗的第一阶段，即在再生剂全部进入双室床后，继续用与再生时相同的速度进水，至大部分再生液被顶出树脂层为止。
c、正洗
置换过程结束后，按运行方式进水进行正洗，至出水符合要求为止。
四、离子交换树脂的保养
1、树脂长期贮存时，为使其稳定，应将其变为中性盐型。
2、树脂应保持充分湿润，如发现树脂变干，切勿直接用水浸泡，以防树脂体积突然膨胀而造成破碎。
此时，应用饱和食盐溶液浸泡树脂，然后再逐步稀释食盐溶液。
3、树脂应尽量保存于室内，周围环境温度尽可能保持在5～40℃，绝不应低于0℃，以防树脂冻结崩裂。
如无条件保存于室内时，则应根据当地气温条件，将树脂贮存于不同的浓度盐水中，食盐溶液浓度与冰点的关系见下表。
保存于室外的树脂，及避免日光直接照射。
食盐溶液的浓度和冰点
4、树脂在使用前，如不进行预处理，也必须充分反冲洗至水耗氧量稳定后，方可再生使用。
