Cov ntsiab lus tseem ceeb thiab cov txheej txheem kev teeb tsa
Screw-hom Thermocouple: Qhov no yog ib qho kev cuam tshuam kev teeb tsa ntawm thermocouple. Nws cov yam ntxwv tseem ceeb yog ib qho kev sib txuas threaded interface thaum kawg ntawm lub raj tiv thaiv (xws li M6, M8, G1/4), uas yuav tsum tau muab ntsia hlau rau hauv lub pre-machined threaded qhov ntawm cov cuab yeej kho. Cov txheej txheem kev teeb tsa xav kom cov khoom raug ntsuas kom muaj lub hauv paus nruj threaded. Nws yog ib daim ntawv ntawm "assembled" thermocouple thiab tsis tuaj yeem siv ncaj qha rau kev ntsuas qhov kub ntawm cov xov xwm hauv cov kav dej; nws tsuas yog tsim nyog rau cov khoom nto lossis kev sib cuag tsis ncaj los ntawm kev tiv thaiv sheath.
Caij nplooj ntoos hlav-clip Thermocouple: Qhov no yog ib qho uas tsis yog- ntsuas qhov ntsuas kub ntawm qhov chaw. Nws siv lub tshuab ua haujlwm - nyob rau hauv lub caij nplooj ntoos hlav tshuab siv lub siab tsis tu ncua (5–20 N), kom ntseeg tau tias qhov kawg ntawm qhov kev xav tau nruj rau kev sib cuag nrog qhov chaw ntawm cov khoom raug ntsuas. Nws yuav tsum tsis muaj qhov drilling lossis tapping, ua tiav "zero- puas tsuaj" installation, thiab tsim nyog rau cov xwm txheej uas qhov drilling lossis ua rau cov qauv raug txwv, xws li nyob rau ntawm qhov chaw tsis muaj qhov, nkhaus qhov chaw, lossis qhov tsis sib xws.

Cov Txheej Txheem Kev Txhim Kho thiab Kev Txhim Kho
Ntsia hlau- hom:
Ua ntej kev teeb tsa, lub qhov threaded yuav tsum tau ntxuav kom tshem tawm burrs thiab roj;
Siv lub torque ciaj ntswj kom nruj raws li cov chaw tsim khoom pom zoo torque (feem ntau 5-10 N·m), tsis txhob overtightening uas yuav ua rau xov stripping;
After removal, it cannot be directly reinstalled; the thread wear must be checked, and the sleeve should be replaced if wear >10%;
Tsis haum rau ntsuas qhov ntsuas kub ntawm cov xov xwm hauv cov kav dej uas muaj zog; qhov tsis muaj cov qauv sealing tuaj yeem yooj yim ua rau xau.
Snap-ntiv nplhaib hom:
Ua ntej kev teeb tsa, ntxuav qhov saum npoo los ntsuas, tshem tawm cov oxide txheej thiab roj (roughness tsawg dua lossis sib npaug li 0.1 hli);
Xyuas kom meej tias lub caij nplooj ntoos hlav compression yog nruab nrab, tsis txhob muaj compression ntau dhau uas tuaj yeem ua rau kev sojntsuam deformation;
Hloov lub caij nplooj ntoos hlav sib dhos tom qab txhua qhov kev tshem tawm (yog tias siv hom khoom siv) kom tsis txhob muaj elasticity;
Muaj peev xwm ua haujlwm ruaj khov rau lub sijhawm ntev hauv qhov kub thiab txias, cov av noo siab, thiab kev co ib puag ncig yam tsis muaj calibration nquag.
Standards Basis thiab Technical Classification
Ob qho tib si ua raws li cov qauv hauv qab no hauv tebchaws thiab thoob ntiaj teb, tab sis txoj kev teeb tsa tsis yog cov qauv kev faib tawm, tab sis tsuas yog daim ntawv thov engineering:
GB/T 16839.1-2018 (sib npaug rau IEC 60584-1): Txhais cov thermoelectric tej zaum-kub sib raug zoo rau calibration hom K, J, E, N, thiab lwm yam;
GB/T 16839.2-2018: Qhia meej cov chav kawm kam rau ua (Class 1/2) rau thermocouples;
JB/T 9238-1999: Qhia meej txog cov kev cai, kev soj ntsuam cov cai, thiab cov cim ntim rau cov khoom siv thermocouples;
JB/T 5582-2014: Siv tau rau armored thermocouples, nrog rau cov qauv snap-ring;
Nco tseg: "Screw-type" thiab "snap-ring type" yog cov ntsiab lus rau kev teeb tsa, tsis yog hom qauv calibration lossis hom qauv. Lawv feem ntau raug cim raws li "daim ntawv teeb tsa" hauv cov khoom catalogs, xws li "WRNT-02K-M6" qhia txog K- hom ntsia hlau hom thermocouple.
Visual Structure Comparison
Ntsia hlau- hom thermocouples yog ib qho kev txhim kho nruj uas siv cov xov sib txuas, haum rau cov xwm txheej nrog ua ntej - teeb tsa lub qhov thiab xav tau ntev - kho; snap-ring thermocouples yog ib qho kev daws teeb meem yooj yim uas siv cov kev sib txuas siab, tsim los rau qhov tsis yog- puas tsuaj, ceev, thiab rov ntsuas qhov kub thiab txias. Qhov ob tsis yog hloov pauv rau ib leeg, tab sis yog ob qho kev sib txuas ntawm lub cev sib txuas cov tswv yim hauv kev ntsuas kub ntsuas tshuab. Qhov kev xaiv yuav tsum yog raws li kev ntsuam xyuas dav dav ntawm cov qauv ntawm cov khoom raug ntsuas, kev saib xyuas zaus, thiab cov txheej txheem yuav tsum tau ua.
