Dab tsi yog vim li cas rau kev sib tiv tauj tsis zoo ntawm qhov kawg kawg ntawm thermocouple thiab tus kwv raug ntsuas?

Cov laj thawj tseem ceeb rau kev sib tiv tauj tsis zoo ntawm qhov kawg ntawm qhov kub thiab cov khoom siv lossis ib puag ncig {0 Cov hauv qab no yog cov lus qhia ntxaws ntxaws:
Txoj kev teeb tsa teeb meem
Insufficient insertion depth: If the thermocouple is not inserted deep enough into the object being measured, the hot end cannot be fully immersed in the measured medium, which will result in a small contact area and insufficient heat transfer. For example, when measuring the temperature of the fluid in the pipeline, if the thermocouple is inserted too shallowly, it can only contact the fluid near the inner wall of the pipeline, and cannot accurately ntsuas cov kua kub ntawm qhov chaw nruab nrab ntawm lub raj xa dej .
Qhov chaw tsis txaus ntseeg: The Thermocouple yog ntsia ntawm lub qhov rooj ntsuas kub, yog tias qhov ntsuas cua sov sab nraud, nyob rau hauv lub qhov rooj cua sov {1}
Tsis pub muaj qhov ntsuas kub thiab tsis muaj qhov sib tiv thaiv kev ntsuas kub thiab cov khoom siv kub yuam kev .
Qhov chaw saum npoo ntawm cov khoom raug ntsuas
Sab Nraud Nrawm: Yog tias muaj qhov tsis sib xws, nplai lossis cov khoom siv cua sov tsis haum, thiab muaj qhov kub thiab txias rau qhov ntsuas kub ntawm lubastting yuav ua rau muaj cov txheej cua nruab nrab ntawm qhov kawg ntawm qhov kawg ntawm thermocouple thiab tus casting, cuam tshuam rau qhov ntsuas kub tshaj plaws yog qhov tseeb.
Muaj av lossis impurities nyob rau saum npoo: av lossis impurities xws li roj, thiab cov khoom siv tuab ntawm cov yeeb nkab roj av, thaum ntsuas cov pa tawm ntawm cov yeeb nkab, cov khoom siv cua sov ntawm qhov kub sov ntawm qhov kawg ntawm lub Thermocouple thiab cov yeeb nkab yuav cuam tshuam, ua rau muaj kev ntsuas kub tsawg.
Cov Khoom Siv Cov Neeg Khoy
Tsis muaj kev sib raug zoo: Tom qab Thermocouple yog ntsia, nws tsis yog qhov ntsuas ntawm qhov kev ntsuas kub, yog tias lub tshuab sib hloov, yog tias nws tsis tsau kom nruj, tus Kub kawg ntawm Thermocouple yuav maj mam rhuav tshem los ntawm nws txoj hauj lwm raws li cov khoom siv khiav, ua rau muaj kev sib cuag tsis zoo.
Kev ntxhov siab ntawm thermal: nyob rau hauv ib puag ncig cua sov, nws yuav ua rau muaj kev ntxhov siab me me, nws yuav ua rau muaj kev ntxhov siab me me, nws yuav ua rau muaj kev ntxhov siab ntau dhau, nws yuav ua rau muaj kev tiv thaiv thermocouple ntau dhau, nws yuav ua rau cov khoom sib tiv thaiv thermocouple, nws yuav ua rau muaj kev sib tiv thaiv thermocouple ntau dhau, nws yuav ua rau muaj kev tiv thaiv thermocouple ntau dhau, nws yuav ua rau muaj kev tiv thaiv thermocouple ntau dhau, nws yuav ua rau cov khoom sib tiv thaiv thermocouple, nws yuav ua rau cov khoom sib tiv thaiv thermocouple nyob rau hauv kev nthuav dav ntawm cov khoom lag luam Ceramic thiab thermocoed tuaj yeem ua rau muaj qhov kawg ntawm lub thermocouple kom muaj kev sib cuag sib tiv tauj nrog cov khoom tsis zoo tom qab siv ntev.
Thermocouple tus kheej cov teeb meem
Deformation ntawm lub tes tsho tiv thaiv: Lub Tsho Tiv Thaiv ntawm Thermocouple yog qhov sib xws los yog kev sib tsoo, nws yuav ua rau muaj kev sib tw sib txawv, nws yuav ua rau muaj kev sib tw sib txawv los ntawm kev ntsuas ntsuas kom yog {}}
Kub xaus kev puas tsuaj: qhov kawg ntawm lub thermocouple yuav raug puas vim yog cov khoom tawg, thiab lwm yam kev ntsuas kev ntsuas, hauv cov khoom siv tsis zoo, hauv cov hluav taws xob muaj zog, ntawm cov hluav taws xob thermocouple kub kawg yog yooj yim corroded, uas nce kev sib chwv tiv thaiv kev tiv thaiv thiab cuam tshuam rau kev ntsuas qhov tseeb {}}
Environmentalency
Kev kub siab rau oxidation kub: nyob rau hauv ib qho kev kub siab ib puag ncig, qhov kawg ntawm kev hloov oxide {{{{{ kub, cuam tshuam rau qhov tseeb ntawm kev ntsuas kub ntawm ntsuas kub.
Tshuaj lom neeg corrosion: yog tias muaj cov roj corrosive, kua, thiab lwm yam kev ntsuas kub, thiab nce kev sib chwv hluav taws xob} nce kev ntsuas tsis raug .
