Yuav ua li cas kuaj qhov tsis kam ntawm hluav taws xob soldering hlau
Hluav taws xob soldering hlau yog cov cuab yeej tseem ceeb rau kev tsim hluav taws xob thiab kev kho hluav taws xob, feem ntau yog siv rau cov khoom siv vuam thiab cov xov hlau. Nws tuaj yeem muab faib ua cov cua sov sab hauv hluav taws xob soldering hlau thiab sab nraud cua sov hluav taws xob soldering hlau raws li cov qauv siv tshuab. Nws tuaj yeem muab faib ua cov tin absorbing hluav taws xob soldering hlau thiab tin absorbing hluav taws xob soldering hlau raws li kev ua haujlwm, thiab tuaj yeem muab faib ua hluav taws xob hluav taws xob hluav taws xob thiab hluav taws xob qis hluav taws xob raws li lub hom phiaj sib txawv.
Kev ntsuam xyuas hluav taws xob hluav taws xob muaj peb ntu: kev ntsuas kev tiv thaiv hauv av (lub xeev txias / kub), qhov ntsuas hluav taws xob, thiab qhov ntsuas tam sim no.
1. Grounding resistance test ntawm hluav taws xob soldering hlau hauv lub xeev txias:
Thaum tsis muaj hwj chim, hu rau ib kawg ntawm lub multimeter sojntsuam nrog lub grounding davhlau ya nyob twg ntawm lub hwj chim plug thiab lwm yam kawg nrog lub ntsis ntawm lub soldering hlau mus kuaj cov ntaub ntawv;
2. Kev ntsuam xyuas hauv av ntawm hluav taws xob soldering hlau nyob rau hauv lub xeev cua sov:
Plug rau hauv lub hwj chim mov, qhib lub soldering hlau, thiab txuas ib kawg ntawm lub multimeter sojntsuam mus rau lub grounding davhlau ya nyob twg ntawm lub roj teeb, thaum lwm kawg yog nyob rau hauv kev sib cuag nrog lub rooj sib tham uas hu rau soldering hlau. Ntsuas cov txiaj ntsig;
3. Kev ntsuas hluav taws xob xau thiab qhov ntsuas tam sim no ntawm cov hluav taws xob soldering hlau zoo ib yam li cov qauv ntsuas kev ua haujlwm. Nws yuav tsum tau muab sau tseg tias lub multimeter yuav tsum tau hloov lub zog los yog kho qhov chaw ntawm lub multimeter sojntsuam hlau thaum ntsuas tam sim no.
Kev tu cov txheej txheem rau hluav taws xob soldering hlau
1. Txoj kev kho rau cov hlau uas tsis kub tom qab tau muab tso rau hauv
(1) Tom qab lub tshuab hluav taws xob hluav taws xob tau muab tso rau, nws pom tias lub taub hau ntawm lub taub hau tsis kub, feem ntau yog vim lub hwj chim qaum poob los yog cov tub ntxhais hlau soldering hlau tawg. Nyob rau hauv rooj plaub no, tus nqi R ntawm lub multimeter tuaj yeem siv tau × Yog tias tus pointer ntawm multimeter tsis txav ntawm ob qho kawg ntawm lub hwj chim ntsaws ntsuas ntawm LKN iav, nws qhia tau hais tias qhov qhib Circuit Court txhaum.
(2) Ua ntej, xyuas seb puas muaj qhov qhib Circuit Court nyob rau hauv cov hlau lead ntawm lub ntsaws nws tus kheej. Yog tias tsis yog, tshem tawm tus kov Bakelite thiab siv lub multimeter los ntsuas ob txoj hauv kev ntawm cov tub ntxhais hlau soldering. Yog hais tias lub multimeter pointer tseem tsis txav, nws qhia tau hais tias cov tub ntxhais hlau soldering puas lawm thiab yuav tsum tau hloov.
(3) Tus nqi tiv thaiv ntawm ob qho tib si ntawm 35W sab hauv rhuab soldering hlau tub ntxhais yog 1. Nyob ib ncig ntawm Skfl, yog tias ntsuas qhov ntsuas tsis zoo yog qhov qub, nws qhia tau tias cov tub ntxhais hlau soldering yog qhov zoo. Qhov txhaum tshwm sim nyob rau hauv lub hwj chim lead thiab lub plug nws tus kheej, thiab feem ntau ntawm cov faults yog vim qhib Circuit Court nyob rau hauv cov hlau lead. Nws yog ib qho tsim nyog los hloov cov tub ntxhais hlau soldering, ntxig ib tug tshiab soldering hlau core ntawm tib yam specification rau hauv lub connecting pas nrig, kho cov hlau lead nyob rau hauv lub fixing ntsia hlau, thiab nruj nreem xaim ncej. Nyob rau tib lub sijhawm, xyuam xim rau kev txiav tawm qhov ntau dhau ntawm cov tub ntxhais hlau soldering hlau ua kom tsis txhob muaj qhov luv luv ntawm ob txoj hauv kev.
2. Txoj kev tu rau lub taub hau hlau nyob
(1) Yog vim li cas rau qhov ua txhaum ntawm hluav taws xob ntawm lub taub hau ntawm lub taub hau tsis yog tsuas yog tias cov hlua hluav taws xob tsis raug txuas mus rau hauv av hlau davhlau ya nyob twg, tab sis kuj hais tias thaum lub hwj chim qaum poob tawm ntawm lub qhov hluav taws xob hlau txuas thiab kov cov ntsia hlau ntawm lub tshuab hluav taws xob. grounding hlau, ua rau lub taub hau hlau soldering yuav electrified.
(2) Hom kev ua txhaum no tuaj yeem yooj yim ua rau hluav taws xob poob siab thiab cov khoom puas. Txhawm rau tiv thaiv txoj hlua hluav taws xob los ntawm kev poob, nws yog ib qho tsim nyog yuav tsum tsis tu ncua xyuas seb cov ntsia hlau crimping ntawm lub xov tooj hluav taws xob tuav yog xoob lossis ploj lawm. Yog tias muaj qhov xoob lossis poob, nws yuav tsum tau npaj raws sijhawm.
