Txoj kev siv tus qauv
1. Kev xaiv thiab kev sib tw
Qhov kub thiab txias: K- hom (-200℃~ 1300 degree) yog qhov kev xaiv zoo dua; S-hom (platinum-rhodium) raug pom zoo rau qhov chaw kub kub.
Xov Specifications: M27 × 2 (tus qauv kev lag luam) lossis 1 "NPT (North American tus qauv) yog nyiam.
Kev xaiv khoom siv:
General corrosive ib puag ncig → 316L stainless hlau
Muaj zog acid / molten ntsev ib puag ncig → Hastelloy lossis ceramic txheej
2. Kev qhia tshwj xeeb rau kev teeb tsa
Qhov thiab Threaded Seat: Lub threaded qhov tshwj tseg rau hauv cov khoom yuav tsum tau machined raws li cov qauv, nrog ib tug xov qhov tob tshaj los yog sib npaug rau 1.5 npaug ntawm nominal xov txoj kab uas hla.
Tightening Torque:
M27 × 2: Pom zoo 40 ~ 60 N·m (tsis txhob overtightening los tiv thaiv deformation ntawm lub raj tiv thaiv)
Siv lub torque wrench; kev ceev ceev yog nruj me ntsis txwv tsis pub.
Insertion Depth: Ntau dua los yog sib npaug li 10 ~ 15 npaug ntawm txoj kab uas hla sab nraud ntawm lub raj tiv thaiv, kom ntseeg tau tias qhov kub kawg yog tag nrho rau hauv nruab nrab.
Sealing Treatment: Sau cov xov sib txawv nrog siab -kub refractory cement lossis asbestos hlua los tiv thaiv cov roj kub kub thiab qhov tsis raug vim yog convection.
3. Thermal Expansion Compensation Operation
Tom qab kev teeb tsa, ua kom sov cov khoom siv rau qhov ua haujlwm kub thiab saib xyuas seb qhov ntsuas ntsuas qhov ntsuas puas ruaj khov.
Yog tias qhov kub thiab txias tshwm sim los yog hloov pauv, nws qhia tau hais tias lub caij nplooj ntoos hlav tsis muaj txiaj ntsig zoo, thiab lub kaum sab xis yuav tsum tau hloov kho lossis hloov lub caij nplooj ntoo hlav.
4. Kev them nyiaj hluav taws xob thiab kev sib tshuam txias
Polarity: Liab hlau (-), Daj hlau (+)
AK- hom sib piv cov nyiaj xaim yuav tsum tau siv, txuas mus rau thaj tsam qhov kub thiab txias ntawm lub txee tswj.
Lub cuab yeej yuav tsum ua kom lub tshuab tsis siv neeg txias qhov sib txuas ua haujlwm kom tsis txhob ua yuam kev los ntawm qhov ntsuas kub hloov pauv.

Calibration Cycle: Calibrate txhua 6 lub hlis nyob rau hauv siab -kub/corrosive ib puag ncig.
Cia siab rau Lifespan: 2 ~ 4 xyoo nyob rau hauv ib txwm ua hauj lwm tej yam kev mob, luv luv nyob rau hauv nquag pib- nres cycles los yog mechanical shock. 1 xyoo
Hloov daim ntawv ceeb toom: Hloov tam sim yog tias qhov kev sojntsuam yog khoov, lub raj tiv thaiv tawg, lossis cov teeb liab tso tawm yog qhov txawv txav.
Kev txwv kev siv:
Tsis txhob tso qhov kev sojntsuam ncaj qha rau hauv siab -kub xov xwm yam tsis muaj preheating los tiv thaiv thermal shock thiab puas.
Tsis txhob siv cov tsis yog -tus qauv threaded adapters, vim qhov no yuav ua rau lub foob tsis ua hauj lwm lossis kev ntxhov siab.
Tsis txhob siv qhov kev sojntsuam raws li kev thauj khoom -cov kabmob; zam kev tawm tsam lossis rub cov hlau lead.
Tsis txhob siv cov hlau lead uas tsis muaj kev tiv thaiv hauv thaj chaw muaj zog sib nqus, vim qhov no tuaj yeem ua rau muaj teeb meem cuam tshuam.
Lub movable threaded thermocouple yog ib txoj hauv kev txhim khu kev qha tshaj plaws hauv kev lag luam siab - ntsuas qhov ntsuas kub. Nws "movable" tsim tau txhim kho cov khoom siv lifespan thiab ntsuas kev ruaj ntseg. Nrog rau kev txhim kho kom zoo, nws tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv qhov chaw hnyav xws li boilers thiab reactors, ua rau nws yog ib qho zoo tagnrho rau welded thermocouples.
