Yuav Ua Li Cas Tiv Thaiv Kev Ua Tsis Zoo hauv Teflon-Sheathed Corrosion-Resistant Platinum Resistance Temperature Detectors

PTF-RTDs nrog Teflon sheaths ua haujlwm zoo nyob rau hauv corrosive industrial settings, txawm li cas los xij sheath corrosion, rwb thaiv tsev degradation, thiab kev teeb tsa tsis zoo yog cov teeb meem tshwm sim. Yuav kom ua tau zoo, kev tiv thaiv yuav tsum tau ua raws li txoj hauv kev uas suav nrog plaub ntu: xaiv cov khoom tsim nyog, kev teeb tsa tus qauv, tswj ib puag ncig, thiab kuaj tsis tu ncua.




I. Txhim kho cov qauv tsim kom muaj kev nyab xeeb rau lub cev



Siv ob - lossis ntau- txheej txheej txheej txheej: Ua kom cov khoom tiv taus ntau dua rau kev yaig thiab kev nkag mus, siv cov qauv sib xyaw xws li "stainless steel tiv thaiv tube + sintered PTFE txheej" lossis "PTFE + hnav- cov txheej txheem tiv thaiv sab nrauv (xws li PFA lossis silicon carbide).



Xaiv lwm cov ntaub ntawv uas tuaj yeem tiv taus qhov kub thiab txias: Thaum kub mus ze rau 250 degree, PFA (perfluoroalkoxy) yog qhov kev xaiv zoo dua li tus qauv PTFE vim nws muaj thermally ruaj khov thiab tsis tshua muaj qhov muag thiab hloov cov duab.



Xyuas kom cov qauv sealing ua tau raws li qhov xav tau ntawm cov txheej txheem: Xaiv txoj cai fastening flanges los yog xov specifications raws li yuav ua li cas cov kav dej txuas nrog kom tsis txhob muaj kev sib khi tsis zoo los ntawm kev ua tsis zoo thaum lub sijhawm teeb tsa.



II. Xyuas kom tseeb tias cov txheej txheem kev teeb tsa yog tib yam thiab tib neeg tsis ua rau kev puas tsuaj



Tsis txhob khoov ntau dhau: Lub vojvoog dabtsi yog khoov thaum lub sijhawm teeb tsa yuav tsum yog tsawg kawg 50mm kom cov hlau platinum sab hauv los ntawm kev tawg vim muaj kev ntxhov siab.



Tswj Tightening Torque: Txhawm rau kom tsis txhob overtightening, uas tuaj yeem tawg lub plhaub los yog ua kom puas lub sealing nto, siv lub torque ciaj ntswj rau threaded sib txuas.



Tsim nyog ntawm- Kev Tiv Thaiv Qhov Chaw: Tsis txhob siv cov cuab yeej ntse thaum txhim kho kom cov PTFE txheej tsis txhob khawb, uas yuav ua rau nws tsis tshua muaj corrosion.



III. Ua kom qhov chaw khiav hauj lwm zoo li ua tau thiab txo qis kev pheej hmoo sab nraud



Tswj Nruab Nrab Kub Kub: Txhawm rau kom lub plhaub tsis muaj zog thiab kev laus, xyuas kom meej tias qhov ntev - lub sijhawm ua haujlwm kub tsis dhau 220℃thiab luv luv - lub sij hawm kub siab tsis tshaj 250℃.



Txhim kho qhov khoov khoov lossis kev txhawb nqa ruaj khov rau siab - cov twj tso kua mis lossis cov kav dej kom txo tau qhov cuam tshuam ntawm kev co tsis tu ncua ntawm cov ntsiab lus vuam thiab cov hlau lead.



Khaws cov thawv ntim khoom kom qhuav thiab huv: Siv tag nrho - cov thawv yas los yog stainless hlau hlws ris uas yuav tsis xeb, thiab xyuas kom meej tias lub nplhaib sealing zoo kom tsis txhob ya raws thiab cov terminals tsis xeb.



IV. Teeb tsa kev tshuaj xyuas tsis tu ncua kom ntes tau teeb meem ntxov



Ua Kev Ntsuas Hluav Taws Xob: Siv lub ntsuas hluav taws xob 12kV los kuaj xyuas lub hnab txhua 6 mus rau 12 lub hlis kom pom cov teeb meem zais zoo li micropores thiab tawg tam sim ntawd.



Tshawb xyuas cov rwb thaiv tsev tiv thaiv: Siv lub megohmmeter los xyuas cov rwb thaiv tsev ntawm qhov kev sojntsuam thiab cov casing tsis tu ncua. Tus nqi ib txwm yuav tsum yog tsawg kawg yog 100MΩ. Yog tias nws tsawg dua 1MΩ, koj yuav tsum tau saib rau hauv nws.



Txheeb xyuas cov xwm txheej ntawm cov hlau lead txuas: xyuas kom cov terminals tsis xoob lossis corroded. Txhawm rau kom paub tseeb tias peb -xov hlau them yog raug, huv thiab nruj raws li xav tau.



V. Ua kom ruaj khov thiab tswj kev thauj mus los



Siv peb txheej ntawm kev tiv thaiv ntim: ib qho "anti- lub hnab zoo li qub + cushioning ua npuas ncauj + noo noo- pov thawj lub thawv" tsim rau kev xa khoom. "Precision Instruments" thiab "Shockproof" yuav tsum tau sau rau ntawm lub thawv.



Tsis txhob khaws cia rau sab nraud ntev. Hloov chaw, khaws cia rau hauv qhov chaw qhuav, zoo- lub tsev tso pa tawm kom deb ntawm cov kua qaub thiab cov hauv paus kom nws tsis txhob xeb lossis ntub dej ua ntej koj siv.



Lus Ceeb Toom Tseem Ceeb: Tus yuam sij rau kev tiv thaiv yog "nip teeb meem hauv pob." Nyob rau hauv lawv cov theem thaum ntxov, ntau malfunctions tsis tso tawm tej yam tshwm sim tshwm sim. Peb tsuas tuaj yeem txav los ntawm kev saib xyuas rov qab mus rau kev saib xyuas tsis tu ncua los ntawm kev tshuaj xyuas tsis tu ncua thiab khaws cov ntaub ntawv.
