Kev Saib Xyuas Txhua Hnub Kev Ua Haujlwm thiab Kev Tshawb Nrhiav Tsis Ua Haujlwm rau Split-Semicircular Combined Cartridge rhaub
Split-semicircular ua ke cartridge rhaub belongs rau kev cai sib sau ua ke cua sov tivthaiv. Nws txoj kev tsim dual-ntu coj qhov tshwj xeeb kev saib xyuas zoo tib lub sijhawm qhia cov khoom kuaj xyuas ntxiv rau cov khoom siv hluav taws xob monolithic cartridge rhaub. Raws li cov ntaub ntawv khaws cia ntawm cov khoom siv-tu-chaw haujlwm, ntau qhov ua tsis tiav ntxov tuaj yeem ncua sijhawm lossis zam dhau los ntawm kev tshuaj xyuas tsis tu ncua. Kev kho kom pom tseeb suav nrog kev sib dhos-interface nruj, lub davhlau ya nyob twg-kawg sealing kev ncaj ncees, sheath-surface carbon-deposit accumululation thiab thermocouple-cim nqi stability. Kev nkag siab meej txog qhov ua tsis tau zoo ib txwm txhawb nqa kev kuaj mob sai ntawm qhov chaw.
Kev tshuaj xyuas lub sijhawm pom kev tsom mus rau ntau txoj haujlwm tseem ceeb. Kev sib koom ua ke sib txawv ntawm ob ntu ntu ntu xav tau kev soj ntsuam rau qhov tshwm sim offset raws li thermal-cycling cuam tshuam. Terminal-kawg sealing nto yuav tsum tau kuaj xyuas rau carbonization, tawg los yog ya raws-nruab nrab kab. Cov pa roj carbon deposits thiab roj paug nyob rau hauv sheath txheej txheej ua rau thermal kuj thiab hinder tshav kub dissipation. Kev ntxuav ua haujlwm tshem tawm cov pa roj carbon deposits thiab greasy av yam tsis muaj kev puas tsuaj sheath hlau nto. Built-in thermocouple tso zis teeb liab tsim nyog rau kev kuaj xyuas raws sij hawm. Qhov txawv txav txawv txav los yog qhov zoo li qub offset qhia txog qhov muaj peev xwm sib tshuam hloov chaw los yog rwb thaiv tsev degradation hauv cov kab noj hniav semicircular.
Hom tsis ua hauj lwm muaj xws li ib ntu tsis muaj cua sov, qhov sib txawv ntawm qhov kub thiab txias ntau dhau, lub teeb liab thermocouple dhia thiab sealing cheeb tsam carbonization. Ib ntu poob-ntawm- cua sov feem ntau cuam tshuam nrog kev tiv thaiv sab hauv-xaim kev tawg lossis lub davhlau ya nyob twg-cov hlau lead disconnection ntawm ib chav tsev semicircular. Cov ntu sib tshooj tseem tuaj yeem ua kom sov. Multi-meter kuj ntsuas qhov txawv ntawm qhov txhaum nyob rau hauv cov cua sov Circuit Court los yog lwm cov hlua hlua. Kev sib txawv ntawm qhov kub thiab txias ntau dhau yam tsis muaj kev puas tsuaj rau cov khoom siv feem ntau yog los ntawm kev sib dhos unilateral ncua kev sib cuag lossis tsis sib haum nrog lub zog sib piv. Thermocouple teeb liab dhia feem ntau cuam tshuam nrog hauv av-voj cuam tshuam lossis sab hauv thermocouple-txoj kev xoob hauv cov kab noj hniav semicircular.
Cov lus qhia txog kev tsis ua hauj lwm hom kev kuaj mob yog qhia raws li hauv qab no:
表格
| Fault Phenomenon | Possible Root-Cause | Yam khoom kuaj thawj zaug |
|---|---|---|
| Ib ntu semicircular nres cua sov, counterpart ua haujlwm ib txwm | Internal resistance-hlau tawg los yog lead disconnection | Kev ntsuas ntsuas rau txhua qhov cua sov sab nraud |
| Pom tseeb qhov sib txawv ntawm qhov kub thiab txias yam tsis muaj qhov cuam tshuam qhib-circuit | Unilateral ncua kev sib cuag los yog tsis tsim nyog lub hwj chim-ratio configuration | Txheeb xyuas qhov kev sib dhos haum thiab kev tswj fais fab-qhov ntsuas qhov ntsuas |
| Sporadic thermocouple-sib qhia dhia | Lub suab nrov hauv av lossis xoob thermocouple hlws ris hauv kab noj hniav | Tshawb xyuas cov thermocouple shielding-wiring thiab internal sensor los ua ke mob |
| Terminal-kawg sealing carbonization thiab rwb thaiv tsev-ua haujlwm poob | High-temperature aging, noo noo nkag mus, deg carbon-deposit tsub zuj zuj | Kev soj ntsuam pom rau qhov chaw sib khi, ntsuas kev tiv thaiv kev tiv thaiv hauv qab 500 VDC |
Raws li kev paub txog kev ua haujlwm zoo, thaum ib ntu tsis ua haujlwm tshwm sim, kev hloov pauv tsuas yog lub hom phiaj puas tsuaj ib puag ncig es tsis yog tag nrho cov txheej txheem sib dhos. Spare-part yuav tsum muaj qhov sib npaug ntawm qhov sib npaug, qhov ntsuas hluav taws xob thiab kev teeb tsa thermocouple raws li thawj ntu. Cov khoom seem tsis sib xws yuav ua rau qhov sib npaug ntawm qhov sib npaug thermal tom qab hloov. Tom qab hloov cov commissioning yuav tsum xyuas kom meej sib dhos symmetry, rwb thaiv tsev-tiv taus tus nqi thiab thermocouple-cim nqi stability ua ntej yuav rov qab tsim cov ntaub ntawv.
Kev saib xyuas kev ua haujlwm rau kev sib cais-semicircular ua ke cartridge rhaub sib txawv ntawm cov khoom siv hluav taws xob monolithic. Kev tshuaj xyuas ywj pheej rau txhua ntu semicircular thiab kev sib dhos-interface yam tsis tuaj yeem raug tshem tawm. Built-in thermocouple kev noj qab haus huv cov ntaub ntawv ua qhov tseem ceeb tshuaj xyuas yam khoom. Kev cob qhia kev koom ua ke-txhim kho kev taw qhia txhais cov npe tshawb xyuas lub sijhawm thiab kev kuaj xyuas qhov tsis raug, txhawb kev ua haujlwm ntev ntev rau kev cai cais-semicircular cua sov sib dhos.
