Yuav Ua Li Cas Tiv Thaiv Kev Ua Tsis Zoo ntawm Ob Chav -Conduit Installed Junction Box-Type Platinum Resistance Temperature Detectors

Txhawm rau kom tsis txhob muaj teeb meem nrog ob npaug -conduit ntsia hlws ris lub thawv- hom platinum tiv thaiv qhov ntsuas kub, koj yuav tsum tau ua kom zoo dua plaub qhov chaw: tsim kev xaiv, txheej txheem kev teeb tsa, kev tiv thaiv ib puag ncig, thiab kev saib xyuas. Qhov no yuav tiv thaiv kev ua tsis tiav.




I. Tsim Kev Xaiv Qhov Zoo Tshaj Plaws: Ua kom lub hauv paus ruaj khov dua



Txhim kho Cov Tube Cov Khoom Siv: 904L stainless hlau lossis Hastelloy C-276 yog cov khoom siv zoo tshaj plaws sab nrauv rau cov chaw uas muaj chloride ions, H₂S, lossis cov kua qaub muaj zog. Nws yog ntau tshaj peb zaug li resistant rau pitting corrosion li 316L. Lub raj sab hauv muaj cov txheej txheem sintered PTFE uas ua kom cov qhov tsis xws luag tshwm sim thaum lub sij hawm 12kV txim kuaj, uas ua rau corrosive tawm los ntawm kev nkag mus.



Lub zog sealing system:



Lub nplhaib sib khi rau lub thawv sib txuas yog ua los ntawm fluororubber (FKM) lossis silicone roj hmab (VMQ). Nws tuaj yeem tswj tau qhov kub ntawm -40 txog 200 degrees Celsius thiab kav ntev tshaj 50% ntev dua nitrile roj hmab. Movable flange interface muaj ob lub foob ua los ntawm cov hlau kauv qhwv gasket thiab hloov tau yooj yim graphite gasket. Qhov no ua kom paub tseeb tias nws seals zoo txawm tias qhov kub thiab txias siab.



Cov Hlau Hlau Zoo dua: Cov hlau lead hlau yog ua los ntawm cov nyiaj -plated tooj liab- clad steel, uas ua rau lawv 40% muaj zog dua thiab tsis tshua muaj kev cuam tshuam los ntawm qaug zog thaum caij tsheb kauj vab ntau zaus. Ib qho redundant arc nyob rau hauv cov duab ntawm ib tug S uas yog tsawg kawg yog 200 hli ntev yog khaws cia nyob rau hauv kev twb kev txuas ntawm cov hlau lead thiab lub hlws ris lub thawv kom tsis txhob concentrating mechanical stress.







II. Kev Tswj Xyuas Kev Txhim Kho Cov Lus Qhia: Tau Txais Kev Ruaj Ntseg Los Ntawm Tib Neeg



Thermal Displacement Compensation: Qhov sib txawv ntawm yam tsawg kawg 5 hli yog sab laug kom swb thaum lub installation ntawm flange txav tau. Qhov no yog ua kom cov yeeb nkab tiv thaiv los yog cov hlau lead los ntawm kev khoov lossis tawg vim yog cov kav dej thermal expansion thiab contraction. Lub cuab yeej laser alignment yog siv los xyuas coaxiality, nrog qhov sib txawv ntawm Tsawg dua lossis sib npaug li 0.1 hli.



Kev tiv thaiv rau lub thawv sib txuas:



Lub hau rau lub thawv sib txuas yuav tsum tig ntsej muag thaum nws tau teeb tsa sab nraud, thiab cov khoom siv cable yuav tsum fim. Muaj lub hau npog stainless hlau los nag thiab silica gel desiccant uas hloov xim. Cov no muab tso rau hauv thiab muab tawm txhua peb lub hlis.



Lub cable inlet muaj lub caj pas tsis muaj dej nrog qib IP68 tiv thaiv kom tsis txhob muaj dej tawm.



Lead Wire Wiring Specifications: Koj tsis tuaj yeem ncaj los yog bundles coj. Txhawm rau kom cov hlau tsis txhob tawg los ntawm kev qaug zog, ib qho kev hloov pauv ntawm qhov tsawg kawg yog 150mm yuav tsum muab tso rau hauv qhov nkag mus rau lub thawv sib txuas. Siv stainless hlau clamps uas tsis nyiam cov hlau nplaum los kho cov khoom kom tsis txhob cuam tshuam electromagnetic.







III. Environmental Protection System: Nres Corrosion Paths



Anti- Txheej Txheem Txheej Txheem Txheej Txheem: Ib txheej txheej ntawm sintered PTFE nrog lub thickness tsawg kawg yog 1.0mm yog siv rau sab nraud ntawm lub raj. Kev ntsuam xyuas pom pom tias tsis muaj micropores. Hauv cov xwm txheej uas cov khoom txav mus sai, ntxiv cov khoom siv ceramic ntxiv- cov txheej tiv thaiv tuaj yeem ua rau cov txheej txheem tiv thaiv-corrosion kav ntev li 8 txog 10 zaug.



Media Isolation Measures: Ib ob -tube configuration yog siv nyob rau hauv corrosive media. Qhov chaw nruab nrab ntawm cov raj sab hauv thiab sab nrauv yog ntim nrog cov cua qhuav lossis cov pa roj inert los muab lub cev tsis muaj zog.



Kev Tswj Kub Kub: Txhawm rau kom platinum xaim los ntawm oxidizing thiab cov khoom siv rwb thaiv tsev los ntawm carbonizing, lub sijhawm ntev - ua haujlwm kub yog khaws cia tsawg dua lossis sib npaug li 500℃. Txhawm rau txo qhov cuam tshuam ntawm thermal stress, cov dab dej kub tau muab tso rau hauv lub thawv sib txuas thaum kub siab.



Kev Tiv Thaiv Ib puag ncig: Lub sijhawm ntev - ua haujlwm kub yog khaws cia ntawm 500℃lossis qis dua kom platinum hlau los ntawm oxidizing thiab rwb thaiv tsev cov khoom los ntawm carbonizing. IV. Tsim Kev Txhim Kho Kev Txhim Kho: Tau Txais Kev Saib Xyuas Kev Ua Haujlwm Ua Haujlwm



Kev tshuaj xyuas tas li



Siv 500V megohmmeter los ntsuas cov rwb thaiv tsev tiv thaiv txhua rau lub hlis. Kev nyeem ntawv ntawm 100MΩ lossis ntau dua yog qhov zoo, tab sis kev nyeem ntawv qis dua 10MΩ rau lub sijhawm ntev yuav teeb tsa lub tswb.



Txheeb xyuas cov nplhaib sib khi txhua peb lub hlis kom pom seb lawv puas tawv los yog tawg. seb lawv puas yog, hloov lawv.



Kev soj ntsuam ntawm qhov xwm txheej



Kev Ntsuam Xyuas Kev Ruaj Ntseg: Sib piv cov ntaub ntawv nrog cov ntaub ntawv sensor thaum lub cev ua haujlwm zoo ib yam; saib mus rau qhov siab - zaus dhia lossis drifts tam sim ntawd.



Thermal Response Time Test: Yog hais tias lub sij hawm teb yog ntau tshaj 30 vib nas this nrog ib tug hloov nyob rau hauv qhov kub thiab txias, koj yuav tsum tau mus xyuas cov kev mob ntawm lub rwb thaiv tsev nyob rau hauv lub sab hauv.



Cov Ntaub Ntawv Teev Tseg: Teeb tsa cov ntaub ntawv khaws cia hauv computer uas khaws cov ntaub ntawv los ntawm txhua qhov kev sim thiab cov phiaj xwm nkhaus. Txav los ntawm "passive hloov pauv" mus rau "kev ceeb toom ntxov ntxov."



Lub ntsiab lus tseem ceeb: 85% ntawm kev ua tsis tiav tuaj yeem zam tau nrog cov kauj ruam tiv thaiv. Qhov tsis pub leejtwg paub yog siv plaub lub hauv paus ntsiab lus ntawm "corrosion- xaiv tiv thaiv + kev hloov pauv hloov + kaw- voj sealing + kev tshuaj xyuas lub sijhawm," uas tuaj yeem ua kom txhua yam ua haujlwm zoo rau ntau tshaj yim xyoo.
