Dab tsi yog qhov yuam kev ntawm clamp-hom thermocouples

I. Kev Nyeem Ntawv Tsawg / Thermoelectric Potential

Qhov teeb meem no feem ntau ua rau qhov ntsuas kub qis dua qhov kub ntawm qhov chaw.


Tsis zoo Clamp Pre-tension

Ntev -lub sij hawm kub kub ua rau hlau annealing thiab clamp elasticity poob, txo clamping quab yuam. Qhov no ua rau huab cua sib txawv ntawm lub thermocouple qhov kawg ntawm qhov ntsuas thiab ntsuas qhov saum npoo, ua rau muaj kev tiv thaiv thermal thiab kub lag lossis kev nyeem qis.

Kev daws: Tsis tu ncua xyuas clamp zawm. Hloov cov clamps xoob los yog distorted tam sim ntawd thiab siv lub cuab yeej torque los txhim kho kom sib npaug.

Tsis txaus kev sib cuag ntawm qhov kawg ntawm qhov ntsuas thiab ntsuas qhov chaw

Thermocouple's sensing point tsis tag rau qhov kub thiab txias vim qhov chaw oxidation, scaling, los yog unevenness.

Kev daws: Ntxuav thiab txhuam thaj chaw ntsuas rau cov hlau ncaj qha - mus rau -hlau kov.

Moisture los yog rwb thaiv tsev puas nyob rau hauv Thermocouple

Cov dej noo los yog cov hmoov av conductive tuaj yeem nkag mus ntawm cov thermoelectrodes thiab vaj tse los ntawm kev sib khi tsis zoo, txo cov teeb liab tawm.

Kev daws: Tshem tawm cov tub ntxhais thermocouple, ziab cov thermoelectrodes thiab insulating ceramic raj, tom qab ntawd xyuas thiab hloov cov khoom sib khi.

Cov teeb meem them nyiaj yug hlau

Moisture, rwb thaiv tsev degradation, thim rov qab polarity, thiab them nyiaj xaim -thermocouple calibration type mismatches tuaj yeem ua rau qhov tsis raug.

Kev daws: Hloov nrog cov nyiaj them rov qab kom raug, xyuas cov polarity, thiab cov khoom siv dej tsis zoo.



II. High Instrument Reading/Thermoelectric Potential

Txawm tias tsis tshua muaj, qhov teeb meem no txo ​​cov kev tswj xyuas qhov tseeb.

Cov cuab yeej tso saib -Thermocouple Mismatch

Yog tias lub thermocouple yog K- hom tab sis qhov ntsuas yog S- hom, tib lub thermoelectric tej zaum yuav raug to taub yuam kev raws li qhov kub ntau dua vim qhov sib txawv calibration.

Kev daws: Match thermocouple thiab ntsuas ntsuas hom.

Sab nraud Heat Source Interference

Yog hais tias lub thermocouple coj mus nyob ze ntawm qhov chaw siab tshaj - qhov kub thiab txias los yog raug tshav ntuj ncaj qha, cov nyiaj them nyiaj xaim lossis lub thawv sib txuas ua kom sov, ua rau qhov tsis zoo ntawm qhov chaw txias txias. Kev daws teeb meem: Txhim kho txoj kev xaim hluav taws xob zoo, zam qhov chaw tshav kub, thiab ntxiv cov cua sov- lub tes tsho insulating.



Fluctuating Display Tus nqi (tsis ruaj tsis khov teeb liab tawm)

Kev nyeem ntawv sib txawv, cuam tshuam tsis siv neeg tswj kev ruaj ntseg.

Clamps uas vibrate los yog ua rau sib cuag

Clamps haum rau cov tshuab vibrating xws li cov twj thiab cov kiv cua tuaj yeem xoob lub sijhawm, tsim kom muaj qhov ntsuas kub tsis sib xws thaum kawg kev sib cuag.

Kev daws teeb meem: Siv vibration-damping brackets thiab anti-loosing washers los yog ob-nut locking structures.

Kev Sib Txuas Tsis Zoo

Tsis ua kom nruj kev sib txuas ntawm cov xov hlau los yog qhov ntev ntev ntawm qhov kub thiab txias oxidizes qhov chaw sib cuag, ua rau muaj teeb meem tsis xwm yeem.

Rov kho cov hlau, ntxuav qhov chaw tiv tauj, thiab siv tshuaj tiv thaiv -oxidation conductive paste los daws teeb meem.

Intermittent Thermocouple Hlau tawg

Micro- tawg nyob rau hauv cov thermocouple hlau vim kev qaug zog lossis kev puas tsuaj me me ua rau muaj kev sib cuag tsis sib xws hauv kev co, cuam tshuam cov teeb liab.

Hloov lub thermocouple tam sim ntawd yog tias qhov ntsuas hluav taws xob hloov pauv tom qab ntsuas nws siv multimeter.

Electromagnetic cuam tshuam

Cov kab hluav taws xob cuam tshuam qhov hluav taws xob tuaj yeem tshwm sim los ntawm kev sib nqus sib nqus nyob ze ntawm cov khoom siv hluav taws xob muaj zog xws li inverters thiab motors.

Kev daws teeb meem: Siv cov kab hluav taws xob them nyiaj hluav taws xob thiab tsis txhob siv hluav taws xob cables thiab cov kav dej nrog cov hluav taws xob muaj zog.



Tsis muaj thermoelectric tej zaum tso zis (tsis muaj zaub lossis yuam kev)

Qhov no feem ntau qhia tau hais tias lub teeb liab Circuit Court tawg.

Thermocouple Hlau tawg

Lub thermocouple hlau tawg vim kev txhim kho khoov, siab -kub embrittlement, lossis kev puas tsuaj.

Txiav thiab reweld yog tias qhov chaw so tso cai; txwv tsis pub, hloov nrog lub thermocouple tshiab.

Broken or Miswired Compensation Wire

Ib qho qhib Circuit Court tshwm sim thaum ib lub xov hlau raug yanked, crushed, los yog miswired.

Tshawb xyuas Circuit Court txuas ntxiv hauv qhov chaw, nrhiav qhov chaw tawg, thiab kho nws. Kev Tiv Thaiv Kev Tiv Thaiv Cov Lus Qhia

Cov kauj ruam no tuaj yeem nce clamp-hom thermocouple kev ntseeg tau:

Tshawb xyuas lub clamp peb lub hlis twg rau kev xoob, deformation, lossis corrosion kom ntseeg tau tias clamping quab yuam sib tw.

Standardize installation: Xyuas kom tseeb tias qhov ntsuas kub ntsuas qhov kawg kov ib tug huv si nto thiab lub clamp yog tusyees stretched.

Txhim kho kev tiv thaiv kab mob: Muab lub thawv sib txuas thiab fim lub qhov hluav taws xob hauv qab kom tsis txhob muaj dej noo thiab plua plav infiltration.

Txhawm rau kom paub meej qhov ntsuas qhov tseeb, ntsuas qhov ntsuas ntawm -site lossis tawm -site txhua 6-12 lub hlis, nyob ntawm kev ua haujlwm.
