Taw qhia rau lub hauv paus ntsiab lus ntawm cov kub kub thiab kev kub siab thermocouple

Kev kub siab thiab kub siab thermocots muaj cov kub corrosion tsis kam thiab feem ntau yog siv rau cov hlau kub-resistant. Cov ntsiab lus muaj roj carbon tsawg, nrog kev txhim kho kev txhim kho corrosion tsis kam, feem ntau yog siv los ua cov hlau kub-resistant hlau. Cov pa roj carbon tsawg thiab zoo intergranular tsis muaj feem ntau siv los ua cov hlau kub-resistant hlau. Ultra tsawg cov ntsiab lus carbon qis, nrog zoo inngranular corranular kam, feem ntau yog siv los ua cov hlau kub-resistant hlau. Nickel based high-temperature alloy steel is commonly used as a heat-resistant steel due to its high temperature oxidation resistance and corrosion resistance.

Thermal ua yuam kev ntawm kev kub siab thiab siab siab thermocouples. Thaum muaj kub kub, yog tias muaj txheej ntawm thee cov tshauv thiab hmoov av txuas rau cov raj tiv thaiv, cov thermal kuj nce, cuam tshuam nrog kev ua kom sov. Lub sijhawm no, kev nyeem ntawv kub yog qis dua tus nqi tseeb ntawm kev ntsuas kub ntsuas. Yog li ntawd, sab nrauv ntawm qhov kub-kub thiab high-siab thermocouple tiv thaiv raj yuav tsum tau ceev kom huv kom txo qhov tseeb. Qhov yuam kev qhia los ntawm cov rwb thaiv tsev tsis zoo. Yog tias qhov kub thiab txias thiab ntau voltej thermocouple yog insulated, cov phaj xov tsis zoo nyob ntawm lub rauv tsis zoo thiab cov hluav taws xob ua kom sov siab rau qhov kub siab. Qhov no tsis yog ua rau ploj ntawm thermoelectric vaj peev xwm tab sis kuj tseem qhia kev cuam tshuam, ua rau muaj qee zaum tau mus txog 100 degrees.

Kev ntsuas kub siab thiab siab siv cov kev thov kub tshwj xeeb rau cov chaw nres tsheb fais fab xav tau ntawm 300000, 600000 kw thiab lwm cov khoom siv thiab lwm yam khoom siv. Ncaj qha ntsuas ntsuas qhov kub ntawm cov kua, vapor, roj xov, thiab cov khoom siv roj nyob hauv thaj tsam ntawm {2} degree c rau 800 degree c hauv ntau cov txheej txheem ntau lawm. Ua haujlwm ua haujlwm: Cov electrodes ntawm thermocouple yog muaj ntawm ob tus neeg sib txawv. Thaum muaj qhov sib txawv ntawm qhov ntsuas kom xaus thiab siv tau kawg, thiab cov ntsuas ua haujlwm tau qhia txog qhov ntsuas kub sib xws nrog lub peev xwm thermoelectric. Thermistor ntsuas qhov kub los ntawm kev siv cov yam ntxwv uas tsis kam ntawm cov tshuaj hloov nrog ntsuas kub. Thaum cov neeg tsis kam hloov pauv, cov ntsuas ua haujlwm ua haujlwm cov txiaj ntsig kub sib xws nrog tus nqi tiv thaiv.
