Kuv yuav ua li cas yog tias lub taub hau soldering yog overheated? Cov kev daws teeb meem yog dab tsi?
Tom qab soldering hlau yog energized, qhov kub yog siab li 250 degrees Celsius. Thaum tsis siv, nws yuav tsum tau muab tso rau ntawm qhov muag muag, tab sis thaum nws tsis siv rau lub sijhawm ntev, lub zog yuav tsum raug txiav tawm kom tsis txhob muaj qhov kub ntawm qhov "hlawv" ntawm cov hlau taub hau (oxidized). Nws yog ib qho tsim nyog los tiv thaiv cov hluav taws xob soldering hlau los ntawm scalding lwm yam khoom, tshwj xeeb tshaj yog cov hlua fais fab. Yog tias cov txheej txheej rwb thaiv tsev raug kub hnyiab los ntawm cov hlau soldering yam tsis tau saib xyuas, nws yuav yooj yim ua rau muaj kev nyab xeeb. Yog li ntawd, qhov kawg ntawm cov hlau soldering tau hlawv dub thiab hlawv.
Soldering hlau taub hau overheating tov:
1. Txiav tawm lub hwj huam mov kom txias
2. Ntxig cov hlau uas tsis siv ib ntus rau hauv cov hlau soldering hlau sawv ntsug, thiab siv cov cua sov hloov mus rau qhov chaw loj ntawm cov cua kub dissipation kom txias cov hlau soldering. Thaum cov hlau soldering raug tshem tawm ntawm cov hlau soldering, cov hlau soldering yuav sai sai mus rau qhov kub thiab txias yam tsis muaj cua sov dissipation ntawm cov hlau soldering.
3. Txuas ib pab pawg nyob rau hauv cov kab hluav taws xob ntawm cov hlau soldering, ib qho kev sib txuas sib txuas uas muaj lub diode 1N4007 thiab hloov. Thaum cov hlau tsis siv rau lub sijhawm ntev, koj tuaj yeem kaw qhov hloov pauv, kom cov hlau soldering tsuas tuaj yeem tau txais ib nrab lub voj voog fais fab zaus, thiab qhov kub yuav tsis overheat; Thaum siv cov hlau soldering, kaw qhov hloov, kom cov hlau soldering yuav tau txais lub zog ib txwm muaj thiab qhov kub yuav nce.
4. Ordinary hluav taws xob soldering hlau tuaj yeem ua rau hauv ib qho yooj yim hluav taws xob soldering hlau sawv ntsug. Ib tug micro hloov yog ntsia nyob rau hauv lub soldering hlau sawv ntsug. Tom qab cov hlau soldering tau muab tso rau, lub rectifier diode txuas nrog hauv series kom txo qhov kub thiab txias. Lub soldering hlau hlawv.
5. Kev ua kom txias txias yog qhov zoo dua rau cov hlau taub hau, thiab kev ua kom txias nrog dej txias yuav ua rau lub neej ua haujlwm ntawm lub taub hau hlau.
Yog hais tias cov hlau soldering yog energized rau lub sij hawm ntev, qhov kub thiab txias yuav siab dhau lawm thiab lub neej kev pab cuam yuav luv luv, thiab lub soldering hlau taub yog yooj yim rau "hlawv" thiab ua rau nws nyuaj rau "noj tin". Kev siv lub zog ntawm qhov chaw ua haujlwm kub tsis tu ncua yog qhov qis, vim tias thaum hloov kho qhov kub thiab txias, qhov cua sov tsis tau nqa tawm, thiab cov khoom siv hluav taws xob sib txuas yog tsawg, uas yog hais tias, tib lub vuam nyhuv, qhov chaw nres tsheb soldering siv. tsawg zog. Koj tuaj yeem xaiv qhov chaw nres tsheb kub tsis tu ncua los daws qhov teeb meem ntawm overheating lub taub hau hlau.
