Kev txiav txim siab seb lub ntsuas hluav taws xob puas xav tau hloov pauv yuav tsum muaj kev ntsuas dav dav los ntawm peb yam: kev saib xyuas kev noj qab haus huv, kuaj lub cev, thiab kev pov thawj tiv thaiv. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog nyob rau hauv siab - qhov kub thiab txias - ib puag ncig cov av noo ntawm Wuhan los tiv thaiv nws los ntawm kev ua tsis tiav vim tsis ua haujlwm ntev thiab cuam tshuam rau kev ntseeg tau ntawm kev hloov pauv ntawm thawj / thaub qab.
1. Kev Saib Xyuas Kev Noj Qab Haus Huv: AI thiab System Early Warning Signals
PHM System Health Weight <0.8: Tus qauv kwv yees ntsuas nws qhov kev ntseeg tau raws li cov ntaub ntawv keeb kwm. Yog tias qhov hnyav tsis tu ncua poob qis dua 0.8, nws qhia tias kev ua haujlwm tsis zoo thiab hloov pauv yog qhov tsim nyog.
Fais fab- ntawm Tus Kheej- kuaj qhov txawv txav: Kev ntsuas kev sib txuas ib ntus txhua hli tau ua. Yog tias qhov kub thiab txias> 1℃/ h lossis nquag nrov nrov tshwm sim, nws qhia tias muaj kev laus hauv lub cev.
Rwb thaiv tsev Resistance Declining Trend: Yog tias ob qhov kev ntsuas sib law liag poob qis dua 20%, txawm tias tseem> 100MΩ, kev hloov pauv yuav tsum tau qhia ua lus ceeb toom.
2. Kev Ntsuam Xyuas Lub Cev: Ntawm -Qhov Kev Ntsuas Xyuas Qhov Chaw
Tsis zoo li qub Circuit Court Resistance: Siv ib tug multimeter los ntsuas lub thermocouple Circuit Court kuj. Qhov ib txwm muaj yog 2 ~ 10Ω. Yog<2Ω (short circuit) or >10Ω (kev sib cuag tsis zoo), nws yuav tsum tau hloov.
Insulation Resistance Test: Use a 500VDC megohmmeter to measure the insulation resistance between the casing and the signal line. It should be >100MΩ Yog<50MΩ and cleaning does not improve the situation, replace immediately.
Terminal Condition: Txheeb xyuas IP67 aviation connectors rau oxidation, corrosion, los yog puas cov ntsaws ruaj ruaj. Txhua yam teeb meem qhia tias tsis muaj kev ntseeg siab.
Kev Pom Zoo Ua Haujlwm: Yuav tsum tau ua "ua haujlwm + rwb thaiv tsev" ob qho kev sim yuav tsum tau ua ua ntej txhua lub hlis twg hloov pauv los tsim kom muaj kev tiv thaiv.
3. Kev Tshawb Fawb Ua Haujlwm: Simulated Activation Test
Infrared Thermometry Reverse Comparison: While the main sensor is operating, measure the temperature of the corresponding nozzle's outer surface using an infrared gun. If the deviation from the system reading is >3 degree, ceeb toom tau tshaj tawm tias lub ntsuas hluav taws xob thaub qab yuav tsis raug yog tias qhib.
Kauj Ruam Teb Ua Ntej-Test: Hloov mus rau qhov chaw thaub qab ib ntus thiab dheev nce lub zog cua sov. Sau lub sij hawm nws yuav siv rau qhov kub thiab txias nce mus rau lub teeb nqi ± 0.5 degree. Qhov no yuav tsum tsawg dua lossis sib npaug li 120 vib nas this; dhau lub sij hawm no qhia tau hais tias ncua sij hawm teb.
Tshaj tawm- Kev Tshawb Fawb Kev Hloov Kho: Tom qab simulating qhov hloov thiab khiav rau 10 feeb, qhov kub thiab txias yuav tsum yog<±1.0℃/min; otherwise, there is a risk of contact instability or aging.
Engineering Standard: Yog tias ib qho ntawm peb qhov kev pov thawj tsis ua tiav, lub sensor thaub qab yuav tsum tau hloov pauv thiab tsis tuaj yeem siv txuas ntxiv mus ua cov khoom siv rov ua dua.
4. Cov xwm txheej tshwj xeeb rau kev hloov pauv (Wuhan High Humidity Special Project)

Qhov xwm txheej |
Kev piav qhia |
|
Twb tau qhib ib zaug |
Lub sensor seem siv tom qab lub ntsiab sensor tsis ua haujlwm; yuav tsum tau hloov thaum lub sij hawm tig tom ntej thiab tsis tuaj yeem siv los ua khoom seem ntxiv. |
|
Khaws cia rau ntau tshaj 180 hnub yam tsis siv |
Txawm tias tsis muaj kev sib hloov, kev hloov pauv yuav tsum raug pom zoo yog tias tsis ua haujlwm rau ntau tshaj 6 lub hlis txhawm rau tiv thaiv kev sib kis thiab kev laus. |
|
Ambient Humidity> 85% RH rau ntau tshaj 7 hnub |
Kev tshuaj xyuas tag nrho tom qab lub caij ntuj nag; Kev hloov pauv yuav tsum tau yog tias tus nqi rwb thaiv tsev yog <80MΩ. |
Kev sib txuas tau noo lossis dej nkag| Tsis hais txog cov txiaj ntsig kev sim tam sim no, cov ntaub ntawv keeb kwm dej noo qhia tau tias muaj kev pheej hmoo siab.
