Soldering hlau tus pas ntsuas kub kub kub hlau
Qhov ntsuas kub-sensing hlau yog ib qho tseem ceeb me me ntawm cov hluav taws xob soldering hlau tus pas ntsuas kub. Qhov kub yog 0-600 degree . Nws tuaj yeem tiv taus corrosion thiab oxidation thiab yooj yim los hloov. Lub tshuab hluav taws xob soldering hlau ntsuas qhov kub thiab txias los ntawm kev kov lub ntsuas kub-sensing hlau.
Thermocouples feem ntau hu ua "thermocouples" thiab muaj ntau hom.
Lub hauv paus ntsiab lus ntawm kev ntsuas kub ntsuas kab:
Muaj 3 terminals ntawm qhov ntsuas kub ntsuas kab, 2 ntawm cov uas tau muab faib ua qhov zoo thiab tsis zoo, thiab qhov thib peb yog rau cov nyiaj tsis siv neeg. Hais txog kev tsim cov kab ntsuas kub, qee qhov yog ob-hlau system thiab qee qhov yog peb-xaim system. Short-circuit qhov "ntxiv /-" ntawm qhov ntsuas kub-sensing kab nrog rau kab thib peb, thiab xaus nrog qhov tso zis kub li qub. Tab sis lub hauv paus ntsiab lus tseem ceeb yog siv cov kev sib raug zoo ntawm ib yam khoom thiab qhov kub thiab txias hloov, thiab tsim ib lub voj kaw los ntawm ob lub conductors nrog cov khoom sib txawv. Thaum muaj qhov kub thiab txias ntawm ob qhov kawg, yuav muaj tam sim no dhau los ntawm lub voj voog. Muaj lub zog hluav taws xob - thermal electromotive force, uas yog hu ua "Seebeck effect". Tom qab lub teeb liab muaj peev xwm tau nthuav dav los ntawm lub amplifier Circuit Court, nws tau hloov mus rau hauv AD teeb liab thiab tso tawm nrog LED lossis pointer.
Thaum kuaj cov hlau taub hau, xyuam xim rau:
1. Ua ntej ntsuas qhov kub ntawm cov hluav taws xob soldering hlau, cov hluav taws xob soldering hlau yuav tsum tau rhuab mus rau qhov kub thiab txias uas tuaj yeem yaj cov tin hlau ib txwm ua ntej kuaj;
2. Khaws cov hlua hluav taws xob thiab qhov ntsuas kub kom huv si, tshem cov tin seem rau ntawm nws, muab cov hluav taws xob soldering hlau ze rau qhov chaw kuaj, thiab tom qab ntawd ntxiv me ntsis tin hlaws rau ntawm qhov kawg ntawm cov hlau soldering;
3. Muab cov hlua hluav taws xob tso rau hauv nruab nrab ntawm cov kab ntsuas kub, 30 degrees nrog cov kab ntsuas kub, khaws cia li ntawm 4-5 vib nas this, thiab qhov kub ntawm lub taub hau soldering yuav tshwm.
