Ib txoj kev los txo qhov kev ntsuas Kev Ntsuas ntawm S - hom Thermocouple
S-type thermocouple yog qhov ntsuas cov cuab yeej siv, tiam sis vim tsis muaj lub luag haujlwm ntawm qhov chaw ua haujlwm, thiab kev ua haujlwm tsis zoo thiab lwm yam, yuav ua rau cov kev soj ntsuam S-type thermocouple ntsuas tau, peb yuav tsum nrhiav kev daws rau lub sijhawm tsis txhob raug ntau lawm. Ntawm no peb tuaj yeem txo qhov kev ntsuas S-hom thermocouple ntsuas txoj kev, vam tias yuav pab txhua tus neeg siv.
(1) nyob rau hauv kev kho lub dag zog ntawm cov khoom tso cai, kom deb li deb tau qhov kev xaiv ntawm cov thermal conductivity thiab diameter ntawm cov nplua thermal electrode khoom, lub diameter ntawm kub electrode yog feem ntau xaiv 0.2-0.5 hli.
(2) kev txhim kho, tus me nyuam tsis tua lub teb kub qhov ntsuas thiab qhov kwv geometry.
(3) S-type thermocouple ntsuas sab yuav tsum tau ntsuas nrog lub rooj thiab ib qho kev sib to taub zoo, tiv tauj rau txoj kev zoo rau txoj kev zoo sib xws (xa mus rau qhov ntsuas los ntawm kev ntsuas vuam). Cov yas pob yas txha tsis pub muaj slag thiab kua paug qhov ntxaij, cov pob yas txha yuav tsum me me, tib lub sij hawm los xyuas kom meej txaus. Txhawm rau txhawm rau txhim kho S-type thermocouple ntsuas ntawm vuam lub zog, lub thermal electrode welded qhov yuav ua tau me ntsis flattened.
(4) tso S-type thermocouple, kom deb li deb tau kom tshem tawm cuam tshuam ntawm kev sib nkag siab. Piv txwv, hauv qhov ntsuas ntawm qhov khiav ntawm cov roj tawm, yog thaum muaj kev pom zoo, S-hom thermocouple zoo siv qhov faus. Tab sis yuav tsum them nyiaj rau qhov me me ntawm qhov chaw me me kom ntau li ntau tau tom qab tso qhov chaw ntawm lub cev yuav tsum muaj teeb pom kev, qhov ntsuas ntws tawm, yog tias qhov ntsuas saum ob lub nquag roj, thiab tsis tso cai rau faus , muab tso rau ntawm cov thermocouple, Yuav tsum tau muaj lub vov khis-zoo li lub hau npog los yog lub hau npog tiv thaiv (pictured), kom txo tau cov cuam tshuam ntawm kev sib nkag siab.
(5) S-type thermocouple ntsuas sab li ze li sai tau rau qhov ntsuas tawm. Rau lub ntsuas huab kheej, qhov kawg ntawm kev ntsuas tau flattened. Thaum ntsuas thermal conductivity ntawm qhov khoom tsawg, koj siv tau cov thermal conductivity ntawm tus neeg siv khoom.
(6) Isothermal ntim tuaj yeem txo cov thermal error. Lub thermal electrode qab lub ntsuas kawg yuav tsum tau pw tsawg kawg yog 50 npaug ntawm qhov ntev ntawm lub kub electrode inch raws lub npoo los ntsuas. Lub thermal electrode raws li kev kuaj lub rooj yuav tsum nyias thiab cov thermal conductivity ntawm cov khoom yog zoo dua los txhim khu lub thermal conductivity ntawm ntsuas nto thiab thermal electrode.
Tom qab cov kub electrode ua rau lub ntsuas nto, lub thermal electrode dimulation txheej txheem yuav tsum tau tuab, adiabatic, los txo cov thermal electrode mus rau airflow kub. Yog tias qhov ntsuas S-hom thermocouple ntsuas voj vev coob dhau lawm, koj tuaj yeem siv txoj kev ntxhib thiab kub electrode ceg tawv, xaiv qhov thickness ntawm ob lub thermal electrode ceg tawv, xyuam xim rau cov thermoelectric zog raws li qhov zoo sib xws.
(7) thaum muaj kev hloov thiab ntsuas kev ntsuas, qhov kev xaiv ntawm S-type thermocouple dynamic lus zoo dua.
(8) cov khoom siv thermal electrode yuav tsum muaj cov thermoelectric cov khoom zoo, ruaj khov thiab tsis meej. Ua ntej cov khoom siv thermal electrode yuav tsum raug kuaj xyuas kom paub tseeb tias cov khoom siv thermal electrode kev ua haujlwm zoo thiab txhim khu kev ntseeg.
