Yog vim li cas rau cov hluav taws xob soldering hlau
Lub ntsiab yog vim li cas rau qhov to ntawm soldering hlau yog tshwm sim los ntawm qhov to ntawm soldering hlau core.
Cov tub ntxhais hlau soldering yog tsim los ntawm cov hluav taws xob cua sov xaim, cov txheej txheem rwb thaiv tsev, thiab txheej rwb thaiv tsev. Thaum cov txheej txheej rwb thaiv tsev yog ntub dhau los yog muaj hnub nyoog ntev dhau lawm, cov txheej txheem rwb thaiv tsev tuaj yeem txo qis, ua rau cov xau ntawm cov tub ntxhais hlau soldering. Tom qab ntawd nws kis tau los ntawm lub tshav kub hloov mus rau lub plhaub thiab lub taub hau ntawm cov hluav taws xob soldering hlau.
Tus kov ntawm cov hluav taws xob soldering hlau kuj tuaj yeem ua rau muaj qhov tsis zoo tom qab kev tshaj lij tshwj xeeb.
Tom qab cov hluav taws xob hluav taws xob hluav taws xob xau hluav taws xob, qhov teeb meem loj heev thiab tuaj yeem ua rau hluav taws xob poob qis, ua rau muaj kev puas tsuaj loj rau tib neeg thiab cov khoom siv hluav taws xob thiab hluav taws xob kho. Thov hloov cov tub ntxhais hlau hlau thiab cov khoom tawg tam sim ntawd, thiab yog tias tsim nyog, hloov lawv tag nrho.
Yuav ua li cas nrog hluav taws xob soldering hlau to
1. Ua ntej, kho lub multimeter rau AC voltage hom. Txuas qhov kev sojntsuam dub rau hauv av thiab qhov kev sojntsuam liab mus rau qhov kawg ntawm cov hlau soldering. Saib seb lub multimeter nyeem. Yog tias muaj kev nyeem ntawv, nws qhia tau hais tias cov hlau soldering yog xau hluav taws xob thiab yuav tsum tau kho.
2. Disassemble cov hlau soldering thiab nrhiav cov cim hauv av. Tom qab ntawd, ua raws li cov xaim hauv av kom pom cov resistor txuas nrog lub rooj tsav xwm hauv Circuit Court thiab ntsuas nws tus nqi tsis kam. Yog tias nws siab tshaj 5 ohms, nws raug txiav txim raws li hlawv tawm thiab yuav tsum tau hloov pauv (feem ntau, qhov resistor no puas vim qhov xau). Yog hais tias tus nqi kuj zoo li qub, thov paub meej tias cov hlau txuas puas muaj kev sib cuag zoo.
3. Tshem tawm cov hluav taws kub hnyiab thiab hloov nrog ib qho tshiab. Nco ntsoov tias txawm hais tias qhov kev tawm tsam ntawm qhov resistor yog 0 ohms, nws ua haujlwm rau lub hom phiaj tiv thaiv. Tsis txhob luv-circuit cheeb tsam no!
4. Tom qab hloov, siv ib lub multimeter kom paub meej tias tus nqi kuj ntawm cov chaw taws teeb ntsuas ntawm cov resistor thiab hauv av.
6. Tom qab kev kho tiav lawm, siv lub multimeter kom paub meej tias qhov kev tiv thaiv tus nqi ntawm cov hlau taub hau thiab cov hlau hauv av. Yog tias tus nqi tiv thaiv nyob rau hauv 2 ohms, nws ua pov thawj tias kev kho tau zoo.
