Kev ceev faj rau kev siv cov tshuaj yaj yeeb yaj kiab thiab cov electrode tu
1. Txuas lub voltage regulator thiab roj teeb ua ntej siv lub ntsuas.
2. Thaum cov khoom siv tshiab uas tsis tau siv rau lub sijhawm ntev, cov khoom siv electrolyte yuav tsum tau muab ntxiv rau hauv cov electrode (tsis li ntawd, cov nqi oxygen yaj tsis tuaj yeem ntsuas tau).
3. rub lub electrode sheath rov qab thiab ntxig cov pa electrode, kom ntseeg tau tias lub ntsaws ruaj ruaj nyob rau hauv kev sib cuag nrog lub qhov (socket), thiab polarize nws rau 5 feeb.
4. Zero oxygen calibration: Muab cov electrode tso rau hauv 5% sodium sulfite tov, thiab qhov zero tso tawm tus nqi yog xoom, qhov zoo dua. Tag nrho cov huab cua calibration: tso saib qhov sib thooj saturated yaj oxygen tus nqi ntawm qhov kub tam sim no. Yog tias muaj qhov sib txawv tseem ceeb, qhov xoom oxygen thiab tag nrho cov nplai calibration tuaj yeem rov ua dua.
5. Lub ntsuas ntsuas yuav tsum tau ntsuas tsis tu ncua thiab hloov nrog electrolyte thiab daim nyias nyias los xyuas kom meej qhov ntsuas qhov tseeb. Yog tias qhov ntsuas tau nquag siv, nws raug nquahu kom ntsuas nws txhua 10 hnub. Thaum txhim kho cov yeeb yaj kiab, nws yog ib qho tsim nyog los xyuas kom meej kev sib cuag ntawm zaj duab xis thiab kub nto, txwv tsis pub nws yuav tsis raug tshem tawm nyob rau hauv xoom oxygen, los yog qhov tseem ceeb yuav tsis raug lossis tsis ruaj khov thaum lub sij hawm ntsuas.
6. Cov pa oxygen electrode yaj siv tau ntev, tshwj xeeb tshaj yog tom qab ntsuas cov dej phwj tsis tu ncua. Cov nyiaj electrode nyob rau hauv lub electrode yuav tig dub thiab oxidize. Nyob rau lub sijhawm no, nws yog ib qho tsim nyog yuav tsum tsis tu ncua hloov cov electrolyte thiab zaj duab xis, thiab ntxuav cov nyiaj electrode thiab kub nto. Yog tias txhua qhov ntsuas tsis zoo, xav txog kev yuav khoom tshiab electrodes.
7. Dissolved oxygen electrodes tuaj yeem khaws cia hauv dej distilled thaum tsis siv. Thaum lub cuab yeej tsis siv sijhawm ntev, lub roj teeb yuav tsum raug tshem tawm.
8. Thaum lub sij hawm kuaj thiab ntsuas, cov electrode yuav tsum txav mus rau qhov kev daws teeb meem thiab yuav tsum tsis txhob nyob twj ywm (them maj mam nplawm).
Siv thiab tu ntawm Hash Dissolved Oxygen Analyzer Electrodes
1. Cov electrode ntawm lub ntsuas oxygen yaj yuav tsum tau ntxuav ib zaug txhua 1-2 lub lis piam. Yog tias muaj cov pa phem rau ntawm daim nyias nyias, nws tuaj yeem ua rau kev ntsuas yuam kev. Ceev faj tsis txhob ua kom lub diaphragm puas thaum ntxuav. Yaug cov pa oxygen meter electrode hauv dej huv. Yog tias cov av tsis tuaj yeem raug tshem tawm, ua tib zoo so nrog cov ntaub mos muag lossis paj rwb.
2. Qhov xoom taw tes thiab ntau yam ntawm cov pa oxygen meter electrode yuav tsum rov ua dua txij Lub Ob Hlis mus txog Lub Peb Hlis.
3. Kev rov tsim dua tshiab ntawm cov pa oxygen analyzer electrode yog nqa tawm kwv yees li ib xyoos ib zaug. Thaum qhov ntsuas qhov ntsuas tsis tuaj yeem hloov kho, nws yog ib qho tsim nyog yuav tsum rov tsim dua cov pa oxygen electrode. Electrode regeneration muaj xws li hloov cov electrolyte sab hauv, hloov daim nyias nyias, thiab ntxuav cov nyiaj electrode. Yog tias muaj oxidation pom ntawm cov nyiaj electrode, nws tuaj yeem polished nrog cov ntawv xuab zeb zoo.
4. Yog hais tias cov pa oxygen analyzer electrode leaks thaum siv, cov electrolyte yuav tsum tau hloov.
