【技术天地】TRO报警故障检修【TechnologyField】
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 befo
re being nt 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;
录音机的英文(1) Normal: dull sound with load, about 2~3 times every 2 conds.
advertir
(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 ca, generally air pump does not ring or just ring once for a long time (dozens of conds);
(3)无水：嘭、嘭、嘭，比较轻快的快速响动，大约1s/2 次。
赤壁赋翻译(3) No water: sounds comparatively light and fast, about 2 times per cond.
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 (e 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 cau water leakage) (diaphragm replacement e 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 (e 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）。
ensure
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 en entering in the detection glass wall (if the drug does not not ENTER, the dosing pipe should be flushed veral times).
3.观察CLX 检测腔内的取样水是否变红
3. Obrve 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.git
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 increa 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 obrved 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：apm是什么意思
sacked
1) If the glass detection chamber is pink (light red), plea 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：
bandwidth
(1) PRIME+ Enter (<--) once, check whether the first TRO value becomes significantly lar
ger (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:
