Dab tsi yog qhov lifespan ntawm threaded -mount box- hom platinum resistance tus pas ntsuas kub
Tso lus
Tus qauv tsim lub neej ntawm threaded -mount box- hom platinum tsis kam ntsuas kub (xws li tus qauv WZP-231) yog 5-10 xyoo. Txawm li cas los xij, hauv cov ntawv thov kev lag luam tiag tiag, nws lub neej ua haujlwm tau zoo yog nyob ntawm qhov chaw ua haujlwm, kev teeb tsa zoo, thiab cov tswv yim txij nkawm, thiab tsis yog tus nqi ruaj khov. Nyob rau hauv cov xwm txheej zoo (tsis muaj zog vibration, tsis muaj corrosive media, sealing zoo, thiab kev saib xyuas tsis tu ncua), nws cov ntsiab lus tseem ceeb ntawm qhov ntsuas kub (platinum hlau) tuaj yeem ua haujlwm ruaj khov rau ntau tshaj 10 xyoo. Txawm li cas los xij, nyob rau hauv ib puag ncig hnyav xws li tshuaj lom neeg, metallurgical, thiab fais fab kev lag luam, feem ntau luv luv rau 2-5 xyoos. Lub ntsiab tsis ua hauj lwm stems los ntawm degradation ntawm cov qauv thiab kev tiv thaiv system, es tsis txhob platinum hlau nws tus kheej.
I. Cov yam tseem ceeb cuam tshuam rau lub neej
|
Influencing Dimension |
Qhov xwm txheej tshwj xeeb |
Mechanism ntawm Influence ntawm Lifespan |
|
|
High Temperature (>300 degree) |
Accelerates platinum hlau oxidation thiab rwb thaiv tsev cov ntaub ntawv aging, nce txhua xyoo drift tus nqi |
|
High Humidity / Condensation |
Txo cov rwb thaiv tsev tiv thaiv sab hauv lub thawv sib txuas, ua rau kom xau thiab luv luv |
|
|
Ib puag ncig tej yam kev mob |
Corrosive Media (Cl⁻, H₂S) |
Pitting corrosion tshwm sim hauv 304 stainless hlau sheath, thiab nruab nrab hu rau platinum hlau tom qab perforation |
|
Muaj zog vibration / Thermal Cycling |
Rov qab khoov ntawm tus neeg xyuas pib ntawm lub hlws ris lub thawv inlet ua rau hlau qaug zog tawg |
|
|
|
Kev tiv thaiv ntsuas (IP) |
IP65 thiab hauv qab no yog cov dej nkag mus, IP68 tuaj yeem txuas lub neej ntev dua 30% |
|
Tus Qauv Tsim |
Cov khoom siv tiv thaiv tube |
316L stainless hlau muaj 50% zoo corrosion kuj tshaj 304, ua rau lub neej ntev |
|
Sealing Ring Khoom |
Silicone sealing rings withstand kub ntawm -60℃mus rau 200 degree, thaum zoo tib yam roj hmab tsuas withstands 120 degree |
|
|
|
Xov Loosening Kev Tiv Thaiv Kev Ntsuas |
Tsis siv ob lub txiv ntseej lossis cotter pins nce qhov xoob ntawm 70% |
|
Kev txhim kho thiab tu |
Tus Thawj Coj Txheej Txheem |
Txhim kho cov xaim los ntawm kev quab yuam ua rau muaj kev ntxhov siab, ua rau muaj kev pheej hmoo ntawm kev tawg los ntawm 4 zaug. |
|
Rwb thaiv tsev |
resistance should be tested every 6 months to detect deterioration trends early. |
Cov ntaub ntawv tseem ceeb: Cov kev sim tiag tiag los ntawm cov tuam txhab xws li Xiamen Shenjie qhia tau tias cov xov tooj platinum tiv thaiv tus pas ntsuas kub siv 316L + IP68 + silicone foob + nkhaus thaiv ua tiav qhov nruab nrab ntawm 6.8 xyoo hauv cov tshuaj reactors, ze li ob npaug ntawm cov qauv zoo tib yam.
II. Hom Txoj Kev ntawm Kev Txom Nyem
Xyoo 1-2: Rwb thaiv tsev stabilizes ntawm 100-500 MΩ, tsis kam drift<0.1 Ω/year
Xyoo 3-5: Kev laus me ntsis ntawm lub nplhaib sealing, rwb thaiv tsev tsis kam poob mus rau 10-50 MΩ, nrog kev hloov pauv tsis tu ncua.
Xyoo 5-7: tooj liab patina thiab dej stains tshwm nyob rau hauv lub thawv hlws ris, rwb thaiv tsev tsis kam<1 MΩ, resistance drift >0.5 Ω
Xyoo 7 thiab saum toj no: Qhov tshwm sim ntawm tus neeg xyuas pib qaug zog tawg tau nce ntau, nrog rau kev qhib Circuit Court txhaum ntau tshaj 60%.
Failure Warning Threshold: Thaum lub rwb thaiv tsev tiv thaiv tsis tu ncua poob qis dua 10 MΩ, los yog tus nqi tiv thaiv deviates los ntawm tus nqi nominal los ntawm ntau tshaj ± 0.5 Ω, yuav tsum pib qhov kev ntsuam xyuas hloov, es tsis tos kom tsis ua tiav.
III. Engineering xyaum ua rau Extending Lifespan
Anti-loosing Design: Yuav tsum siv "ob lub txiv ntoo + cotter tus pin" ua ke los tiv thaiv cov xov unwinding.
Kev Tiv Thaiv Hlau: Ib qho loj dua lossis sib npaug ntawm 150mm arc -zoo li tus redundancy yog muab nyob rau ntawm lub hlws ris lub thawv nkag kom tsis txhob muaj zog tensile.
Environmental Isolation: Kev teeb tsa sab nraum zoov yog nruab nrog cov npog los nag thiab cov khoom siv los txo cov dej noo nkag.
Kev Saib Xyuas Kev Kho Mob: Cov ntaub ntawv tiv thaiv kev tiv thaiv kev tiv thaiv raug tsim, nrog rau peb lub hlis twg cov ntaub ntawv kaw thiab nkhaus plotting rau kev saib xyuas.
Kev pom zoo kev lag luam: 70% ntawm qhov kawg- ntawm- lub neej tshwm sim tshwm sim los ntawm kev tsis muaj kev saib xyuas, tsis yog cov khoom qub qub. Kev tu tsis tu ncua, zawm, thiab kev sim tuaj yeem ua rau lub neej ntev mus rau qhov txwv tsim.
