Hauv kev ntsuas kub ntawm kev lag luam, cov flange ruaj khov -mounted junction box type platinum resistance thermometers thiab caij nplooj ntoos hlav-loaded platinum resistance thermometers yog ob hom kub sensors tsim rau kev ua haujlwm sib txawv. Txawm hais tias ob qho tib si yog raws li lub hauv paus ntsiab lus ntawm platinum tsis kam, lawv sib txawv hauv cov qauv tsim, kev teeb tsa, kev thov scenarios, thiab kev saib xyuas. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau kev ntsuas qhov tseeb, txuas ntxiv cov cuab yeej siv lub neej, thiab ua kom zoo rau kev ua haujlwm thiab cov nqi tu.
I. Tus Qauv Tsim: Flange Rigid Sealing vs Spring Elastic Contact
Lub flange ruaj khov -mounted hlws ris lub thawv hom platinum tiv thaiv tus pas ntsuas kub txais lub flange sealing qauv, nrog rau cov hauv qab no nta:
Flange Connection: Qhov kawg ntawm lub raj tiv thaiv yog welded los yog sib xyaw ua ke nrog flange (xws li, DN25 PN1.6, DN50 PN10). Lub ntsej muag flange tuaj yeem tiaj tus, tsa, lossis grooved, txuam graphite lossis hlau kauv qhov txhab gaskets rau kev sib khi, haum rau siab - qhov chaw siab (10-40 MPa). Lub flange tsim tsim ib qho kev sib txuas tsis sib xws los ntawm kev sib txuas ntawm cov ntsia liaj qhov rooj, ua kom muaj kev ruaj ntseg hauv siab - kub, siab - siab, los yog muaj zog vibration ib puag ncig.
Integrated Junction Box: Lub thawv sib txuas thiab cov raj tiv thaiv yog cov qauv sib cais tsis sib xws, feem ntau yog ua los ntawm cam khwb cia txhuas lossis stainless hlau, nrog IP65 tiv thaiv kev ntsuas. Nws muaj ceramic los yog mica insulated terminals nyob rau hauv, txhawb peb -hlau los yog plaub-xov tooj sib txuas, thiab ua tiav cov nyhuv Faraday tawb los ntawm lub hauv paus ntsia liaj qhov rooj los tiv thaiv electromagnetic cuam tshuam.
Rigid Structure: Tsis muaj cov ntsiab lus sib txuas, ua rau muaj kev nruj nruj thiab ua haujlwm zoo heev rau kev vibration thiab thermal stress, ua rau nws tsim nyog rau cov ntawv thov uas xav tau ntev - lub sij hawm ruaj khov.
Lub caij nplooj ntoos hlav-loaded platinum tiv thaiv tus pas ntsuas kub txais lub caij nplooj ntoos hlav elastic hu rau tus qauv, nrog rau cov hauv qab no nta:
Caij nplooj ntoos hlav Loading Mechanism: Qhov kawg ntawm lub raj tiv thaiv yog nruab nrog lub caij nplooj ntoos hlav thauj khoom, uas siv lub siab tas li ntawm 10-20N los ntawm lub caij nplooj ntoos hlav, kom ntseeg tau tias qhov ntsuas kub ntawm cov khoom nyob ze rau qhov chaw ntawm cov khoom raug ntsuas. Qhov kev tsim qauv no muab cov lus teb ceev ceev heev (lub sijhawm teb tuaj yeem qis li 200-500 milliseconds), ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev ntes cov kub hloov pauv ntawm cov khoom siv.
Tsis Muaj Lub Thawv Ncaj Ncees: Cov kev coj tau ncaj qha los ntawm cov raj tiv thaiv, uas ua rau muaj cov qauv sib txuam ntau dua, tab sis yuav tsum tau hloov ua tiav thaum lub sijhawm tu, vim tias kev kho hauv cheeb tsam tsis tuaj yeem ua tau. Lub caij nplooj ntoos hlav-loaded tsim ua kom yooj yim rau kev teeb tsa hauv qhov chaw kaw lossis ntawm qhov chaw tsis sib xws, haum rau cov xwm txheej uas muaj qhov chaw txwv lossis xav tau cov lus teb sai.
Kev hloov pauv tau yooj yim: Kev hloov pauv yooj yim yog ua tiav los ntawm lub caij nplooj ntoos hlav -loading mechanism, tso cai rau kev hloov mus rau qhov chaw ntawm cov duab sib txawv thiab ua kom qhov ntsuas qhov tseeb.
II. Installation Methods: Flange Fastening vs Spring Compression
Cov kauj ruam ntawm kev teeb tsa rau qhov ruaj khov flange mounting hom suav nrog:
Flange welding los yog ntsia liaj qhov rooj kho: Weld los yog ntsia liaj qhov rooj flange phaj rau cov khoom, xyuas kom meej lub flange nto yog tiaj tus thiab tsis deformation.

Kev sib txuas ua ke: Txuas ncaj qha mus rau cov khoom ntsuas; tsis tas yuav tsum tau ntxiv junction box installation cov kauj ruam.
Fais fab- ntawm kev debugging: Txuas mus rau cov cuab yeej tso saib thiab saib seb qhov kev nyeem ntsuas kub puas ruaj khov.
Cov kauj ruam kev teeb tsa rau lub caij nplooj ntoos hlav -loaded hom suav nrog:
Kev npaj nto: xyuas kom meej qhov saum npoo ntawm cov khoom raug ntsuas yog huv, tiaj tus, thiab tsis muaj roj lossis impurities.
Compression installation: Nias lub sensor tiv thaiv qhov chaw ntawm cov khoom raug ntsuas siv lub caij nplooj ntoos hlav mechanism. Tom qab phau ntawv ua ntej- zawm, kho lub caij nplooj ntoos hlav nrog lub cuab yeej.
Kev sib txuas ua ke: Txuas ncaj qha mus rau cov khoom ntsuas; tsis tas yuav tsum tau ntxiv junction box installation cov kauj ruam.
Fais fab- ntawm kev debugging: Txuas mus rau cov cuab yeej tso saib thiab saib seb qhov kev nyeem ntsuas kub puas ruaj khov.
III. Daim Ntawv Thov Scenarios: Siab-Hloov Kev Lag Luam hnyav vs. Cov Lus Teb Ceev
Qhov ruaj khov flange mounting hom nrog junction box yog tsim rau siab -siab, siab - kub, thiab corrosive kua heev scenarios, xws li:
Cracking furnaces thiab hydrogenation reactors nyob rau hauv kev lag luam petrochemical, yuav tsum tau ua hauj lwm rau 850℃kub thiab 10 MPa chav siab.
Cov tshuab cua txias hauv cov chaw tsim hluav taws xob nuclear, yuav tsum muaj kev cia siab ntev - nyob rau hauv ib puag ncig huab cua.

Overheating ceeb toom rau lub cev muaj zog bearings thiab gearboxes, yuav tsum tau teb ceev ceev los tiv thaiv cov khoom puas. Kev tswj qhov kub thiab txias hauv cheeb tsam hauv semiconductor wafer ua haujlwm yuav tsum muaj kev ua haujlwm siab thiab hloov kho sai.
IV. Kev Kho Kom Zoo: Kev Tshawb Fawb Lub Sij Hawm vs
Qhov tseem ceeb ntawm kev kho flange ruaj khov- hom mounted yog nyob rau hauv kev tshuaj xyuas lub sijhawm ntawm flange foob, xws li:
Tshawb xyuas cov flange bolts xoob peb lub hlis twg los xyuas kom meej tias lub sealing gasket tsis laus.
Calibrating ib xyoos ib zaug, txheeb xyuas qhov tseeb nrog cov qauv ntsuas kub (xws li dej khov- dej sib tov).
Lub caij nplooj ntoos hlav-loaded hom, ntawm qhov tod tes, nyiam hloov ceev, xws li:
Hloov tag nrho cov sensor thaum lub caij nplooj ntoos hlav los yog qhov kev hnov mob puas lawm, tsis txhob kho ib feem.
Kev saib xyuas yuav tsum tau kaw thiab depressurization, ua rau cov nqi hloov pauv ntau dua, tab sis cov txheej txheem kev teeb tsa thiab kev saib xyuas yog yooj yim dua.
V. Summary: Qhov kawg Trade-tawm ntawm Engineering Value
Ob leeg ua tau raws li IEC 60751 Pt100 tus qauv raug, tab sis cov qauv txiav txim siab txog thaj tsam ua haujlwm:
Cov flange ruaj khov-mounted hom yog "sturdy fortress" rau siab-siab kev lag luam hnyav, ua tiav ntev-lub sij hawm ruaj khov los ntawm nruj flange sealing, haum rau siab -siab, siab- kub qhov xwm txheej.
Lub caij nplooj ntoos hlav-loaded hom yog "qhov hloov pauv hloov tau" rau cov kev xav tau nrawm, ua tiav cov lus teb sai thaum lub caij nplooj ntoos hlav-loaded elastic contact, haum rau cov xwm txheej uas yuav tsum tau ua haujlwm tshwj xeeb.
