Yuav Ua Li Cas Siv Qhov Kev Kawm Thermocouple rau Cov Kws Kho Mob Tshiab?

Ib qho kev cob qhia kev cob qhia rau cov kws kho mob tshiab kom ntseeg tau tias lawv tau txais cov txuj ci tsim nyog los txhim kho, kuaj xyuas, thiab tswj cov kub khiav thermocouples yam tsis muaj kev puas tsuaj lossis ua yuam kev. Qhov kev zov me nyuam yuav tsum muab faib ua peb theem: theoretical, practical, thiab ntawm - txoj haujlwm -. Theem 1: Txoj Kev Kawm (Chav Kawm). Npog cov hauv paus: thermocouple yog dab tsi, Seebeck effect, thermocouple hom (J, K, N), qib raug, thiab lawv yuav ntsuas li cas. Piav qhov kub khiav qhov system thiab lub luag haujlwm ntawm thermocouples hauv kev tswj qhov kub thiab txias. Qhia txog cov khoom tseem ceeb: cov sojntsuam, cable, connector, thiab maub los. Sib tham txog hom kev ua tsis tiav: qhib Circuit Court, luv Circuit Court, drift, thiab suab nrov. Qhia cov cuab yeej kuaj mob: multimeter, megohmmeter, pyrometer, thiab calibrator. Cov theem no yuav tsum suav nrog cov lus nug kom paub meej. Kauj Ruam 2: Cov Tswv Yim (Rhiav). Ob txhais tes- ntawm kev tawm dag zog ntawm kev teeb tsa kev sib tw kub kub. Xyaum txhim kho thiab tshem cov thermocouples siv lub torque ciaj ntswj los siv qhov tseeb torque. Xyaum ntsuas kev tiv thaiv, rwb thaiv tsev tsis kam, thiab millivolt tso zis. Ua ib qho kev xeem txuas ntxiv, kev ntsuas hluav taws xob, thiab kev ntsuas ntsuas ntsuas. Siv lub pyrometer los ntsuas qhov kub thiab txias ntawm lub rhuab thaiv thiab sib piv nrog tus maub los nyeem ntawv. Xyaum kuaj xyuas qhov ntsuas kub tsis raug siv cov kauj ruam -los ntawm - kauj ruam flowchart. Txhua tus kws tshaj lij yuav tsum ua kom tiav "kev kuaj xyuas" qhov twg lawv nruab ib lub thermocouple, txheeb xyuas nws cov haujlwm, thiab kuaj xyuas qhov ua yuam kev simulated. Theem 3: Ntawm -the-Txoj hauj lwm (Kev cob qhia). Tus kws tshaj lij tshiab raug xa mus rau tus kws qhia paub txog ib lub sijhawm (piv txwv li, 2 lub lis piam). Lawv ua haujlwm ua ke ntawm cov haujlwm tu vaj tse tiag tiag, nrog tus kws cob qhia muab kev taw qhia thiab kev tawm tswv yim. Tus kws tshaj lij tshiab pib pom, tom qab ntawd maj mam siv lub luag haujlwm ntxiv hauv kev saib xyuas. Tus kws cob qhia ntsuas tus kws tshaj lij txoj kev txawj ntse hauv: xaiv cov khoom seem kom raug, txhim kho kom raug, txhais cov ntaub ntawv kuaj mob, thiab sau cov ntaub ntawv hloov. Thaum kawg ntawm kev cob qhia, tus kws cob qhia muab qhov kev ntsuam xyuas zaum kawg. Qhov kev cob qhia yuav tsum tau them rau kev nyab xeeb: kev pheej hmoo ntawm kev kub nyhiab ntawm qhov chaw kub, kev pheej hmoo ntawm hluav taws xob poob siab, thiab kev siv cov cuab yeej tiv thaiv tus kheej kom raug (cov hnab looj tes, tsom iav kev nyab xeeb). Lub cav yuav tsum tau khaws cia rau txhua tus kws tshaj lij, sau lawv cov kev ua tiav. Kev cob qhia tshiab yuav tsum tau ua txhua xyoo los hloov kho kev paub. Los ntawm kev nqis peev hauv kev cob qhia kev cob qhia, cov nroj tsuag ua kom cov kws tshaj lij tshiab muaj peev xwm thiab muaj kev ntseeg siab, txo qhov kev pheej hmoo ntawm kev teeb tsa tsis raug thiab kuaj xyuas cov teeb meem kom raug, txo qis qis thiab txhim kho kev ntseeg tau tag nrho.
