Yuav ua li cas siv cov cua sov sab hauv soldering hlau?
Lub taub hau ntawm cov cua sov sab hauv hluav taws xob soldering hlau yog ntxig rau hauv cov tub ntxhais hlau soldering. Nyob ntawm lub hwj chim, nws tuaj yeem siv tau tom qab 2 mus rau 5 feeb ntawm lub hwj chim. Qhov siab tshaj plaws kub ntawm cov hlau taub hau tuaj yeem ncav cuag li 350 degree. Feem ntau siv cov khoom siv hluav taws xob sab hauv xws li 20W, 25W, 30W, 50W, thiab lwm yam. Rau kev kho cov khoom siv hluav taws xob, ib qho 20-30W sab hauv cov cua sov soldering hlau feem ntau txaus.
Cov qauv ntawm cov cua sov sab hauv soldering hlau
Lub hauv paus cua sov hluav taws xob soldering hlau muaj lub plhaub, ib tug kov, ib tug soldering hlau taub, ib tug soldering hlau core, thiab ib tug hwj chim qaum. Tus kov yog ua los ntawm cov hluav taws kub-resistant bakelite thiab yuav tsis puas los ntawm cov cua sov ntawm cov hlau soldering. Lub taub hau hlau yog ua los ntawm tooj liab liab, thiab nws qhov zoo muaj kev sib raug zoo nrog qhov zoo ntawm vuam. Cov tub ntxhais hlau soldering yog ua los ntawm nyias cov nickel-chromium tsis kam hlau qhov txhab ntawm lub raj plooj (porcelain tube). Raws li ib txwm muaj, nws tus nqi kuj yog 1 txog 3 kΩ nyob ntawm lub zog. Lub plhaub hlau tub ntxhais feem ntau yog ua los ntawm seamless steel raj, yog li nws yuav tsis deformed vim overheating. Qee cov cua kub ceev ceev yog ua los ntawm cov raj tooj dag. Vim lawv cov cua kub ceev ceev, lawv yuav tsum tsis txhob siv nrog lub hwj chim rau lub sijhawm ntev, txwv tsis pub tus kov yuav puas. Cov ncej khi yog ua los ntawm tooj liab screws thiab yog siv los ua kom ruaj ntseg ntawm cov tub ntxhais hlau thiab lub zog qaum.
Kev siv cov cua sov sab hauv soldering hlau
Ua ntej siv cov hlau soldering tshiab, siv lub tshuab multimeter los ntsuas qhov tsis kam ntawm ob qho kawg ntawm lub zog qaum. Yog tias qhov tsis kam yog xoom, nws txhais tau hais tias muaj kev sib cuag nrog cov hlau sab hauv. Koj yuav tsum disassemble nws, disconnect cov hlau thiab ntsaws rau hauv; Yog tias tsis muaj kev tiv thaiv, nws feem ntau yog cov tub ntxhais ntawm cov hlau soldering. Los yog cov hmoov txhuas puas lawm; Yog hais tias qhov tsis kam yog li 3kΩ, ntsaws rau hauv lub hwj chim dua. Tom qab ob peb feeb ntawm lub hwj chim, khaws cov hlau soldering thiab poob rau hauv lub rosin. Feem ntau yuav tsum muaj pa luam yeeb thiab lub suab "squeaking". Thaum lub sij hawm no, dip lub soldering hlau nyob rau hauv nws kom lub tin Dip lub soldering hlau tag nrho rau hauv nws rau soldering.
