kub tsis khov
Nws yog ib qho qub rau T12 tshiab kom paub qhov kub thiab txias thaum thawj zaug nws siv. Nws yuav tsum muaj hnub nyoog ib ntus kom ruaj khov. Kev ua haujlwm tshwj xeeb: ua ntej teem qhov kub ntawm 250 degree rau tin lub taub hau, tom qab ntawd kho qhov kub ntawm 350 degree rau 30 vib nas this, tua lub zog thiab tos kom nws txias rau hauv chav tsev kub, rov ua haujlwm ob zaug, thiab nws yuav ruaj khov. tom qab siv qeeb.
Lub soldering hlau yog ntsaws rau hauv, tab sis nws tseem qhia tias lub ntsiab lus soldering hlau tsis pom
Qhov tshwm sim no txhais tau hais tias lub taub hau ntawm lub taub hau thiab lub tes tsho tsis nyob hauv kev sib cuag zoo. Tshawb xyuas seb lub taub hau hlau puas tau muab tso rau hauv tag nrho, thiab seb lub shrapnel ntawm PCB bracket nyob rau hauv tus kov thiab lub taub hau soldering hlau yog nyob rau hauv ib txwm sib cuag. Kev sib cuag ncaj qha nrog lub hau ntawm cov hlau soldering
Lub taub hau ntawm cov hlau soldering hlawv liab
Lub T12 soldering hlau taub yog ib qho kev sib xyaw ua ke nrog lub tshuab cua sov, lub sensor thiab lub taub hau. Thaum qhov tshwm sim no tshwm sim, lub sensor tawm ntawm kev tswj hwm thiab yog qhov tseem ceeb hauv lub xeev tsis tuaj yeem.
Feem ntau yuav tsum tau hu rau qhov kev pab cuam tom qab muag thiab xa rov qab rau kev kho
Hlawv liab, tsuas yog ib qho laj thawj uas lub ntsuas hluav taws xob luv luv, thiab qhov ntsuas kub tiag tiag ntawm qhov kawg ntawm lub taub hau soldering tsis tuaj yeem paub qhov tseeb. Thaum qhov kub ntawm qhov kawg ntawm lub taub hau ntawm lub taub hau mus txog 520 degrees los yog ntau tshaj, lub hauv ntej ntawm tag nrho cov soldering hlau taub yuav tig liab. Siv cov txheej txheem ntawm kev tshem tawm ua ntej, thiab ncaj qha hloov qhov kov nrog lub zoo soldering hlau kom pom tias nws tseem muaj qhov xwm txheej zoo li no. Yog tsis muaj teeb meem, nws txhais tau hais tias qhov teeb meem yog tus kov. Ntxiv mus xyuas seb lub sensor ntawm cov hlau tuav yog thim rov qab, yog tias lub sensor zoo li qub (qhov no tsuas yog ua rau lub vijtsam kub ntawm lub zog feem ntau yog 18 degree, qhov theoretical kub siab tshaj 560 degree, cov hlau soldering yog liab), thiab Tom qab ntawd xyuas seb lub qhov (socket) rau lub qhov (socket) thiab tsib tus pin qhov (socket) puas yog soldered rov qab. Seb lub teb cov nyhuv raj tsis zoo hlawv, thiab tus kov sensor yog welded reversely. Cov kab kov tsis raug (hloov tus kov kom tshem tawm qhov teeb meem no).
Soldering chaw nres tsheb yuam kev
1. Yog tias lub tshuab cua ntsaws tsis zoo, rov ntsaws nws dua.
2. Cov kab kub ntawm cov thermocouple nyob rau hauv tus kov yog zoo welded, thiab kho vuam yog txaus.
3. Muaj cov burrs lossis cov khoom txawv teb chaws nyob rau hauv qhov ntsuas qhov kub ntawm lub taub hau ntawm lub taub hau, thiab qhov ntsuas kub ntawm qhov txawv txav qeeb. Reinstall tom qab ntxuav.
