Ua kom tiav Phau Ntawv Qhia rau Kev Txhim Kho thiab Siv Kev Tiv Thaiv Kub Kub Nthuav Tawm Cov thawv

Hauv kev ntsuas kub ntawm kev lag luam, cov ntsuas kub tsis kam tiv thaiv (RTDs) yog cov ntsuas kub uas siv ntau tshaj plaws nyob rau hauv nruab nrab thiab qis kub ntau, thiab lawv qhov tseeb thiab ruaj khov muaj kev ntseeg siab heev. Lub thawv sib txuas, uas yog ib qho tseem ceeb ntawm RTD, tsis tsuas yog cuam tshuam qhov zoo ntawm cov teeb liab kis tau tus mob tab sis kuj cuam tshuam rau kev nyab xeeb thiab kev ua neej ntawm tag nrho cov kev ntsuas. Niaj hnub no, peb yuav tham txog qhov nthuav dav txog kev ceev faj rau kev teeb tsa thiab siv RTD hlws ris thawv.

I. Nkag siab RTD Junction Boxes

RTD hlws ris lub thawv ua haujlwm ua tus choj txuas RTD qhov ntsuas qhov ntsuas kub rau cov khoom ntsuas thiab tswj qhov system. Nws lub luag haujlwm tseem ceeb yog los tiv thaiv cov terminals los ntawm ya raws, plua plav, thiab corrosive media intrusion; hauv qee daim ntawv thov tshwj xeeb, nws kuj tseem muab kev tawg - pov thawj ua haujlwm. Nyob ntawm daim ntawv thov ib puag ncig, cov thawv sib txuas tuaj yeem muab faib ua ntau hom, suav nrog cov dej tsis zoo, tawg- pov thawj, yas, thiab stainless hlau.

Classification thiab Application Scenarios of Resistance Temperature Detector (RTD) Junction Boxes:

Waterproof Junction Box: Haum rau damp lossis qhib- huab cua qhov chaw; txheem configuration rau RTDs.

Explosion-proof Junction Box: Haum rau qhov chaw tawg thiab tawg; tus qauv teeb tsa rau kev tawg- pov thawj RTDs.

Plastic Junction Box: Tsim nyog rau qhov chaw muaj corrosive heev; txheem configuration rau corrosion -resistant platinum RTDs.

Stainless Steel Junction Box: Haum rau corrosion - tiv taus los yog nplaim taws thiab tawg ib puag ncig; elegant tsos, tus nqi siab dua.

Integrated Temperature Transmitter Junction Box: Tshwj xeeb tsim rau kev sib xyaw RTD kub transmitters nrog kub transmitters.

II. Kev npaj ua ntej Junction Box Installation

Kev Ntsuam Xyuas Kev Pom Zoo: Ua ntej kev teeb tsa, ua ntej kos lub thawv sib txuas rau kev puas tsuaj. Cov tubing tiv thaiv yuav tsum tsis muaj zog thiab tsis muaj xeb thiab khawb; txuas threads yuav tsum du; tag nrho cov khoom yuav tsum tau ruaj ntseg thiab txhim khu kev qha.

Qauv Matching: Xaiv qhov tsim nyog hom RTD hlws ris lub thawv raws li kev ntsuas ib puag ncig thiab cov khoom raug ntsuas. Piv txwv li, lub thawv dej tsis sib haum yuav tsum raug xaiv rau qhov chaw ntub dej, thiab qhov tawg - pov thawj lub thawv yuav tsum raug xaiv rau qhov chaw tawg thiab tawg.

Kev ntsuam xyuas ib puag ncig: Ntsuas qhov chaw teeb tsa kom ntseeg tau tias qhov ntsuas kub ntawm lub thawv sib txuas tsis tshaj 100℃thiab nyob ruaj khov li sai tau. RTD yuav tsum tsis txhob muab tso rau ze ntawm lub qhov cub lossis ze rau cov khoom siv cua sov.

III. Junction Box Installation Points

Kev Xaiv Qhov Chaw Xaiv: RTD yuav tsum tsis txhob muab tso rau ze ntawm lub qhov cub lossis ze rau cov khoom cua sov. Nws yuav tsum tau muab tso rau hauv ib qho chaw uas muaj tsawg heev los yog tsis muaj kev vibration, thiab yooj yim rau kev tsim kho thiab tu. Lub installation txoj hauj lwm yuav tsum yog ntsug li sai tau, tab sis yuav tsum tau tilted thaum muaj ndlwg tshaj tawm. Lub qhov hluav taws xob qhov hluav taws xob yuav tsum tig mus rau hauv qab.

Installation Qhov tob: Qhov tob tob ntawm RTD tuaj yeem txiav txim siab raws li qhov xav tau ntawm qhov chaw tiag tiag, tab sis yuav tsum tsis txhob tsawg dua 8-10 npaug ntawm txoj kab uas hla ntawm RTD lub raj tiv thaiv sab nraud. Rau RTDs ntsuas qhov kub ntawm cov kua dej ntawm qhov chaw ntawm cov yeeb nkab, qhov ntsuas qhov kawg yuav tsum tau muab tso rau hauv nruab nrab ntawm cov yeeb nkab.

Sealing Treatment: Rau cov thawv ntim dej tsis sib haum, yuav tsum tau them nyiaj tshwj xeeb rau kev teeb tsa lub nplhaib sealing. Lub hlws ris lub thawv npog thiab lub cev yog txuas nrog threads. Tightening quab yuam kom ntseeg tau tias lub nplhaib sib khi yog sib npaug ntawm ib ncig ntawm lub voj voog, kom ntseeg tau tias txawm tias thaum muaj huab cua phem los yog cov pa phem, tsis muaj qhov nkag mus rau hauv lub thawv sib txuas yuav tshwm sim.

IV. Kev Tiv Thaiv Kev Tiv Thaiv thiab Kev Tiv Thaiv

Kev xaiv hlau: Cov xaim txuas ntawm RTD thiab cov cuab yeej tso saib yuav tsum tau insulated tooj liab hlau (xws li nrog ib txheej thaiv), nrog tus ntoo khaub lig- thaj tsam loj dua lossis sib npaug li 1.0 square millimeters. Tus nqi ntawm cov hlau tsis kam yuav tsum tau sib phim raws li cov kev qhia tshwj xeeb ntawm cov khoom siv ntsuas.

Kev Siv Hluav Taws Xob: RTDs muaj peb txoj kev xaim: ob-hlau, peb- xaim, thiab plaub- xaim. Ob - xov hlau tsuas yog tsim rau cov ntawv thov nrog qhov ntsuas qhov tseeb; peb- xaim xaim tuaj yeem tshem tawm cov kev cuam tshuam ntawm cov hmoov txhuas zoo dua thiab yog qhov feem ntau siv hauv kev tswj cov txheej txheem; plaub-cov xaim xaim tuaj yeem tshem tawm tag nrho cov kev cuam tshuam ntawm cov hlau lead ua haujlwm thiab feem ntau yog siv rau siab - qhov ntsuas kub kom paub meej.

Kev Siv Hluav Taws Xob: Thaum xaim, ua ntej qhib lub thawv sib txuas, thiab tom qab ntawd txuas cov xov hlau raws li cov kab hluav taws xob xaiv. Qhov kom zoo dua ntawm peb -kab sib txuas yog tias nws tuaj yeem zam qhov kev qhia yuam kev ntawm cov khoom siv ntsuas los ntawm qhov kev tiv thaiv tus nqi ntawm cov xov hlau txuas. Xyuas kom meej tias tag nrho cov xaim muaj kev ruaj ntseg thiab txhim khu kev qha, tsis muaj qhov xoob.

V. Kev tu thiab saib xyuas thaum siv

Kev tshuaj xyuas tsis tu ncua: Tsis tu ncua xyuas qhov xwm txheej ntawm lub raj tiv thaiv. Yog tias pom oxidation lossis deformation, ua haujlwm tam sim ntawd. Nyob rau tib lub sij hawm, ua calibration tsis tu ncua los xyuas kom meej qhov tseeb ntawm qhov ntsuas kub.

Rwb thaiv tsev saib xyuas: Lub rwb thaiv tsev ntawm RTD hlau thiab cov raj tiv thaiv, nrog rau kev rwb thaiv tsev ntawm RTD hlau / raj tiv thaiv thiab hauv av, yuav tsum zoo. Txwv tsis pub, kev cuam tshuam tsis raug yuav tshwm sim, cuam tshuam rau kev ua haujlwm ib txwm ntawm lub ntsuas.

Yog hais tias deformation, tawg, los yog puas nyob rau hauv lub junction box casing, siv yuav tsum tau nres thiab hloov qhov chaw. Kev saib xyuas tshwj xeeb yuav tsum tau them nyiaj rau kev tiv thaiv luv luv ntawm cov hlau txuas sab nraud thiab cov cua sov xaim / tub ntxhais hlau, kom ntseeg tau tias qhov hluav taws xob tshem tawm tsis pub tsawg dua 8 hli thiab qhov deb ntawm qhov tsis pub tsawg tshaj 10 hli.

VI. Countermeasures in Special Environments

High-qhov kub thiab txias: High-kub resistant cables los yog siab-kub them nyiaj hluav taws xob yuav tsum tau siv. Thaum ntsuas qhov kub siab tshaj 400 degree, thermocouples feem ntau suav hais tias dhau RTDs.

Corrosive Ib puag ncig: Yog tias RTD yuav tsum tau siv rau hauv cov xov xwm corrosive, yuav tsum siv lub raj tiv thaiv ua los ntawm cov hlau tsis muaj steel lossis lub thawv yas sib txuas.

Ib puag ncig nplaim taws thiab tawg: Hauv ib puag ncig zoo li no, kev tawg-cov ntaub ntawv pov thawj yuav tsum tau siv. Cov thawv sib txuas tshwj xeeb no txwv tsis pub muaj qhov tawg ntawm cov pa roj sib xyaw hauv cov casing vim muaj cov pa taws lossis arcs hauv lub thawv sib txuas.

VII. Cov lus qhia tshaj lij los ntawm Hequan Instrument Technology Co., Ltd.

Raws li lub tuam txhab tshaj lij hauv kev ntsuas kub, Hequan Instrument Technology Co., Ltd., nrog rau xyoo ntawm kev lag luam kev paub, nkag siab tob txog qhov tseem ceeb ntawm RTD hlws ris thawv hauv qhov ntsuas kub. Peb pom zoo:

Tsis tu ncua tswj thiab ua haujlwm rau RTD hlws ris lub thawv, ntxuav cov plua plav thiab cov khib nyiab, thiab tshuaj xyuas kev laus ntawm cov ntsaws ruaj ruaj; xaiv qhov tsim nyog ntawm lub thawv sib txuas raws li qhov chaw ua haujlwm, thiab tsis txhob siv cov thawv sib txuas hauv ib puag ncig tshwj xeeb; nruj me ntsis raws li cov txheej txheem kev khiav hauj lwm thaum lub sij hawm installation los xyuas kom meej txoj hlua khi thiab zoo sealing; tsim kom muaj kev tshuaj xyuas thiab hloov cov txheej txheem rau RTDs ntawm cov txheej txheem tseem ceeb.
