压载水处理系统TRO报警故障检修

一、压载过程

当系统运行压载操作时，出现TRO低报警时，应进行如下检查：

When the system runs ballast operation and TRO low alarm occurs, the following checks should be carried out:

 

1.检查压载水处理系统的取样循环管系

1. Check the sampling circulation piping of the BWTS

1）取样路径：取样口--->取样泵--->检测单元---->CLX口（取样水由取样口取出经取样空气泵加压后送入检测单元，少量水进入CLX进行TRO检测，其余水循环回主管系）。

1) Sampling path:

(sampling water is taken out from sampling port and pressurized by sampling air pump before being sent to monitoring unit, a small amount of water into CLX for TRO detection, the rest of the water cycle back to the main system).

2）由于是取样循环检测，所以每一次检测TRO值是一个检测周期，一般要求最低取样水流速：每一个检测周期内取样水能够从主管系取出并流回主管系。

2) Since it is a sampling cycle test, Each test of TRO value is a test cycle. Minimum sampling water flow rate is generally required: sampled water can be taken from the main pipeline and flow back during each test cycle.

3）可通过听取样空气泵工作声音判断取样水流速：

3) Sampling water velocity can be judged by listening to the working sound of the air pump:

(1)正常：嘭、嘭、嘭，带有负载的沉闷声，大约 2s/2~3 次;

(1) Normal: dull sound with load, about 2~3 times every 2 seconds.

(2)不通：这时空气泵一般不响或者很久（几十秒）响一次;

(2) Blocked: in that case, generally air pump does not ring or just ring once for a long time (dozens of seconds);

(3)无水：嘭、嘭、嘭，比较轻快的快速响动，大约1s/2 次。

(3) No water:  sounds comparatively light and fast, about 2 times per second.

4）取样水不通：

4) Sampling water is blocked:

(1)需要检查取样管系上的手动阀门和检测单元 内部电磁是否开启（电磁阀检修见附录一）；

(1) It is necessary to check whether the manual valve on the sampling pipe line and the internal electromagnetic is opened (see Appendix I for solenoid valve maintenance) ;

(2)需要检查取样管系上的Y型滤器；

(2) Need to check  the Y filter on the sampling pipeline;

(3)检查取样泵控制空气及膜片是否损坏（一般膜片损坏会漏水）（膜片更换见附录二）。

(3) Check whether the control air and diaphragm is damaged (general diaphragm damage will cause water leakage) (diaphragm replacement see Appendix II).

 

2. 检查CLX 药剂

2. Check CLX agents

1）检查CLX 药剂加药时间是否大于2 个月，如果大于2 个月需要更换药剂（见附录三）。

1) Check whether the added time of CLX drug is longer than 2 months. If it is longer than 2 months,the drug should be changed (see Appendix III).

2）如果药剂在有效期内，对投药管系进行清洁，并在清洁结束后进行：同时按PRIME和ENTER键将投药管系中空气和清洁水排出，并可在检测玻璃墙内看到药剂进入（如果药剂没有进入需多次冲洗投药管路）。

2) If the drug is in the period of validity, clean the dosing pipe system, And after the cleaning is finished: press PRIME and ENTER together to discharge the air and clean water in the dosing pipe system, and the drug can be seen entering in the detection glass wall  (if the drug does not not ENTER, the dosing pipe should be flushed several times).

 

 

3.观察CLX 检测腔内的取样水是否变红

3. Observe whether the sampled water in the CLX detection chamber turns red

1)如果没有水进入检测腔需检查1步（前部介绍），如果1步检查完毕且正常需按如下检查。

1) If no water enters the detection chamber, check step 1 (as above). If step 1 is completed and normal, check as follows.

 

如图所示, 1为流量调节阀，向外旋调小流量，向里旋调大流量；2为取样水进检测腔电磁阀，可打开清洁；3 为排水（保持）电磁阀，如果观察到有水流过检测腔但是不能保持， 此处需要清洁；4 为 CLX 进水滤器，需两个月至少清洁一次。

As shown in the figure, 1 is the flow control valve, turn outwardly to reduce the flow, turn inward to increase the flow; 2 is solenoid valve for sampling water into the detection chamber, can be open and clean; 3 is drainage (hold) solenoid valve, if water flow through the detection chamber can be observed but can not keep, it need to be cleaned; 4 is CLX inlet water filter and should be cleaned at least once every two months.

 

1)如果玻璃检测腔粉红色（浅红）请检查1,2,3,步，若1,2,3 步都正常，则进行如下检查：

1) If the glass detection chamber is pink (light red), please check steps 1,2,3. If steps 1,2,3 are normal, then check as follows:

（1）PRIME+Enter(<---）一次，查看 PRIME完后第一次TRO 值是否显著变大（大约 1~3ppm），以及在 PRIME 期间 CLX 泄放管中的取样水是否变红，判断取样水中是否含有 TRO。假若TRO 值变大或者泄放管中取样水颜色显著变红，这时要对注药管路和单向阀进行清洁。如下图所示：

(1) PRIME+ Enter (<--) once, check whether the first TRO value becomes significantly larger (about 1~3ppm) after PRIME, and whether the sampled water in CLX drain pipe turns red during PRIME, and determine whether the sampled water contains TRO. Clean the injection line and check valve if the TRO value becomes large or the sampled water in the drain tube becomes significantly red. As shown in the figure belowed:

(2)如图1所示，拆下主要泵后可以看到A部分的注药管路，将注药管路取出后如图2 所示，白色部分单向阀。单向阀的B部分为主要部件且需要清洁。清洁方法：温水浸泡然后用洁净布片沾水揉擦至迎灯光观察无污物，并擦干。

(2) As shown in Figure 1, after the main pump is removed, the injection pipe in part A can be seen. After the injection pipe is taken out, As shown in Figure 2, and the white part is a one-way valve. Part B of the one way valve is the main component and needs to be cleaned. Cleaning method: soak in warm water and then rub with wet clean cloth until  there is no dirt when observe toward light, and then dry.

(3)清洁完毕，回装。

(3) After cleaning, reinstall.

 

4. CLX 检查

4.The CLX inspection

1) CLX 检测腔样品水观察，如果发现变深红且 CLX TRO 数值一直很低需对 CLX 进行恢复出厂设置。CLX 重置时需要同时下“↑”和“ENTER”等待 CLX 屏幕闪烁一次（3S）后即可恢复出厂设置。

1) Observe the sample water in the CLX detection chamber. If it turns dark red and the CLX TRO value remains low,the CLX should be restored to factory settings. To reset the CLX, you need to press '↑' and 'ENTER' at the same time, waiting the CLX screen blink once (3S) to restore the factory settings.

 

 

2) 4~20mA通信和RS485通信判断，如下图所示，1&2没有接线（只有一组RS485接线）为RS485通信，如果与图2接线一样为4~20mA接线。

2) Judgement for 4 to 20mA communication and RS485 communication. As shown in the following figure, no wiring (only one set of RS485 cables) is used for RS485 communication. If the wiring is the same as that in the figure 2, it is used for 4 to 20mA communication.

 

3) 参数设置步骤

3) Step for setting parameters

恢复出厂设置后，等待下图指示位置（→）移到 AUTO，按键 MODE/EXIT，移动到 CONFIG处，然后按键ENTER(<---) 进入参数设置，可使用按键（↕）选择参数值，使用按键ENTER（<---）确认参数值并进入下一个参数。

After restoring to factory settings, wait for the position indicated in the following figure (→) move to AUTO, press MODE/EXIT, move to CONFIG, and then press ENTER(<--) to enter parameter settings. You can use the key（↕）to select parameter values. Use the ENTER (<--) key to confirm the parameter value and go to the next parameter.

 

 

4）恢复出厂设置后需对 CLX 检测值进行校验。

4) Verify the CLX test value after restoring factory settings.

5. 打压载时TRO 高报警一般是压载主管系的阀门开错了，造成压载水循环电解。

5. When ballasting, TRO high alarm is generally the valve of the main ballast system is opened wrong, resulting in the circulation of ballast water electrolysis.

 

二、卸载过程

二.（Deballast operation）

当系统运行卸载操作时，出现TRO高报警时，应进行如下检查：

When the system runs in deballast opertion and TRO high alarm occurs, the following checks should be carried out:

 

1.检查投药单元

1. Check the dispensing unit

1）排压载时由投药单元加入中和药剂(硫代硫酸钠），中和压载水中的TRO，使排出的压载水不含TRO，保护港口水域生物。

1) When discharging ballast, neutralizing agent (sodium thiosulfate) is added by dispensing unit to neutralize TRO in ballast water, so that the discharged ballast water does not contain TRO and protect the creatures in port waters.

2） 投药过程：投药单元--->注药泵（最大7bar，800ml/min/台）--->注药管系（阀门）--->主管路。

2) Dosing process: 

3）当报警出现是需要如下检查

3) When an alarm occurs, the following checks are required:

(1)检查投药单元是否可以投出药剂（可观察投药单元内部注药泵出口处单向球阀，1，跳动可投出药剂，2，不跳动，不可投出药剂），如果不能投出药剂需要检查投药单元内部电磁阀及注药管系（阀门）。

(1) Check whether dispensing unit can throw the drug (observe the one-way ball valve at the outlet of dispensing unit internal injection pump, 1, jumping to throw the drug, 2, not jumping, not to throw the drug). If the drug cannot be thrown, check the dispensing unit internal solenoid valve and the injection pipe system (valve).

(2)检查投药单元药剂是否结晶或过期（加入药剂超过一年），如有此现象，清洗投药单元药剂舱并重新加药（投药单元加药步骤见附录四）。

(2) Check whether drug in the dispensing unit has crystallized or expired (more than one year after adding the drug). If so, clean the dispensing unit drug tank and refill the drug (see Appendix IV).

 

2.检查压载水处理系统的取样循环管系：

2.Check the sampling circulation piping of BWTS：

1）取样路径：取样口--->取样泵--->检测单元---->CLX口（取样水由取样口取出经取样空气泵加压后送入检测单元，少量水进入CLX进行TRO检测，其余水循环回主管系）。

1) Sampling path:

(sampling water is taken out from sampling port and pressurized by sampling air pump before being sent to monitoring unit, a small amount of water into CLX for TRO detection, the rest of the water cycle back to the main system).

2）由于是取样循环检测，所以每一次检测TRO值是一个检测周期，一般要求最低取样水流速：每一个检测周期内取样水能够从主管系取出并流回主管系。

2) Since it is a sampling cycle test, each test of TRO value is a test cycle. Minimum sampling water flow rate is generally required: sampled water can be taken from the main pipeline and flow back during each test cycle.
