Yog tias qhov ntsuas kub tsis sib xws tau ntub, nws yuav tsum tau muab tso tawm tam sim ntawd thiab qhuav. Yog tias cov rwb thaiv tsev tsis zoo, nws yuav tsum tau hloov. Tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab av noo ib puag ncig ntawm Wuhan, noo noo tuaj yeem yooj yim ua rau luv luv, drift, lossis teeb liab cuam tshuam, cuam tshuam rau kev tswj qhov kub thiab txias.
1. Kev tuav ceev: Fais fab tuag thiab pib ziab
Tam sim ntawd tso tseg kev siv thiab tshem tawm lub hwj chim: Tiv thaiv kom tsis txhob ya raws los ntawm kev ua kom luv luv los yog corrosion ntxiv, tsis txhob muaj kev puas tsuaj rau kev tswj hwm;
Disassemble lub sensor thiab ntxuav qhov saum npoo: So cov connectors, vaj tse, thiab cov ntsiab lus txuas nrog cov dej cawv tsis muaj dej kom tshem tawm cov dej noo thiab stains sab nraud;
Ua kom qhuav los yog qis -kub ci:
Natural drying: Muab tso rau hauv qhov chaw qhuav, qhov cua kom tsawg kawg 24 teev;
Tsawg- qhov kub thiab txias: Muab tso rau hauv qhov cub kub tsis tu ncua ntawm 60℃rau 4-6 teev (tsis txhob ci ntawm qhov kub kub kom tiv thaiv kev puas tsuaj rau cov qauv sab hauv);
Nitrogen purging kev pab: Yog tias ua tau, tshem tawm sab hauv lub thawv sib txuas nrog nitrogen rau 5 feeb kom nrawm tshem tawm cov dej noo.
2. Tshaj tawm- kev tshuaj xyuas kom qhuav: Xyuas seb nws puas tuaj yeem rov qab los
Table Inspection Item Cov Txheej Txheem Ua Haujlwm Zoo
Circuit Court Resistance 2 ~ 10Ω Ntsuas ob qhov kawg ntawm cov teeb liab kab nrog multimeter
Insulation Resistance >100MΩ (500VDC) Ntsuas qhov tsis kam ntawm lub casing thiab cov teeb liab kab nrog megohmmeter
Zero-point Calibration Response Offset<0.3℃ Observe after performing automatic zero-point calibration
Fais fab - ntawm Tus Kheej -test Stability Tsis muaj drift (<0.5℃/h), no burrs Connect to the system and run for 30 minutes
Engineering Kev Txiav Txim: Yog tias cov rwb thaiv tsev tiv thaiv yog tseem<50MΩ or the drift is >1℃/ h, nws tau txiav txim siab tias nws yuav tsum tsis txhob nqus dej noo thiab yuav tsum tau hloov.
3. Tuav cov xwm txheej tsis hloov pauv: Hloov kho thiab tiv thaiv kev hloov kho tshiab
Hloov nrog lub cim tshiab tshiab: Ua ntej lub siab-ความชื้น- cov qauv tshwj xeeb nrog nano- txheej txheej thiab micro- cua sov caij;
Hloov kho dua tshiab ntawm - qhov kev tiv thaiv qhov chaw: Siv nano- txheej txheej rau cov khoom sib txuas;
Ua kom lub micro- cua sov nyob rau hauv lub thawv sib txuas (automatic activation thaum av noo> 70%RH);
Xyuas kom 3-feeb nitrogen purging ua ntej txhua qhov kaw;
Hloov kho cov txheej txheem calibration thiab txheeb xyuas cov txheej txheem: Tom qab hloov, ua ib qho peb - kauj ruam calibration + 24- teev pov thawj kom ntseeg tau tias AI kev noj qab haus huv qhov hnyav rov qab los rau ntau dua lossis sib npaug rau 0.8.
