Yuav ua li cas yuav ua rau ib lub hwj chim regulator rau ib tug soldering hlau? Fais fab kev tswj rau soldering nrog lawv ob txhais tes: lub tswvyim thiab cov kev qhia ntawv

Devices rau kho cov voltage theem txhab khoom mus rau lub caij cua kub, hams yog feem ntau siv los mus tiv thaiv ntxov ntxov tsis ua hauj lwm ntawm lub soldering ntsis thiab qhov zoo tshaj ntawm soldering. Cov feem ntau schemes rau lub hwj chim regulators comprise soldering dvuhpozitronnye hu keyboards thiab scr pab kiag li lawm ntsia tau rau hauv lub khib. No thiab lwm yam pab kiag li lawm muab lub peev xwm los xaiv tus yam voltage theem. Niaj hnub no siv hauv tsev thiab lub Hoobkas chaw.

Tej yam yooj yim hwj chim regulator Soldering

Yog hais tias koj xav tau ib tug soldering hlau 40 W ntawm 100 W yuav tau mus thov nyob rau hauv Circuit Court triac BT 138-600. Nws ua hauj lwm los ntawm tej lub sine yoj. shear tus nqi thiab cov cua kub kub yuav tau tom siv resistor R1. Neon lub teeb ua hauj lwm pab raws li ib tug qhia tau. Yuav kom muab tso rau nws yog tsis tsim nyog. Thaum lub radiator yog ntsia triac BT 138-600.

tsev nyob

Tag nrho cov tswvyim yuav tsum tau muab tso nyob rau hauv ib tug kaw dielectric vaj tse nyob. Lub siab xav mus ua ib tug tej yam me me ntaus ntawv yuav tsum tsis txhob cuam tshuam kev ruaj ntseg thaum uas siv cov nws. Nco ntsoov tias tus ntaus ntawv ua hauj lwm los ntawm ib tug voltage qhov chaw ntawm 220 V.

Scr hwj chim regulator Soldering

Raws li ib qho piv txwv, xav txog ib tug ntaus ntawv, tsim los rau ib tug load ntawm ob peb watts mus rau pua pua. Cai ntau yam ntawm cov movies hwj chim ntawm tus dais mas nws txawv ntawm 50% mus rau 97%. Tus ntaus ntawv siv ib tug tuav KU103V scr tam sim no tsawg tshaj li ib milliampere.

Los ntawm lub diode VD1 dawb do dhau qhov tsis zoo ib nrab-yoj voltage, muab ib nrab ntawm tag nrho cov hwj chim ntawm tus soldering hlau. Nws yuav tau tom VS1 SCRs thaum lub sij hawm txhua txoj kev ib nrab-cycle. Lub apparatus yog hloov antiparallel diode VD1. Scr positionally tswj los ntawm hauv paus ntsiab lus. Cov generator generates pulses tswv yim nyob rau hauv cov tswj electrode muaj R5R6C1 Circuit Court defining lub sij hawm thiab unijunction transistor.

Tus nab npawj kov resistor R5 txiav txim rau lub sij hawm ntawm qhov zoo ib nrab kev voj voog. Fais fab kev tswj tswvyim yuav tsum tau kub stability thiab zoo nrov tiv thaiv. Qhov no yuav ua shunted tswj cov kev hloov resistor R1.

saw R2R3R4VT3

Generator voltage pulses noj rau 7B thiab ib tug ntev ntawm 10 ms, zoo li tus R2R3R4VT3 saw. Nruab hnub nrig VT3 transistor yog ib tug stabilizing caij. Nws yog tshuab txais nyob rau hauv lub rov qab cov kev taw qhia. Lub hwj chim Circuit Court uas dissipates resistors R2-R4, yuav raug muab txo.

Tsav hwj chim regulator muaj ib tug capacitor S1KM5, resistors - mlt thiab R5 - SP 0.4. Lub transistor yuav siv tau yog.

Board thiab lub vaj tse rau cov ntaus ntawv

Rau los ua ke ntawm lub ntaus ntawv tsim ntawv ci fiberglass board of 36 hli nyob rau hauv lub cheeb thiab 1 hli tuab. Rau cov ntaub ntawv, koj yuav tau siv tej yam khoom, xws li yas thawv los yog tus neeg mob ntawm ib cov khoom uas zoo rwb thaiv tsev. Koj xav tau ib tug puag nyob rau hauv cov diav rawg ntsiab. Rau lub hom phiaj no tus ntawv ci tej zaum yuav mus solder lub ob ceev 2,5 M thiaj li hais tias cov pins yog pressed board mus rau lub tsev nyob thaum lub sij hawm los ua ke.

Tsis zoo SCRs KU202

Yog hais tias lub hwj chim ntawm ib tug me me soldering hlau, kev cai no tsuas tau nyob rau hauv ib tug nqaim ib nrab-cycle. Lub ib qhov twg hauv lub mas voltage SCRs tsawg kawg yog me ntsis qis dua lub load tam sim no. Kub stability yuav tsis tau tiav los ntawm kev siv xws li ib tug hwj chim regulator rau soldering.

Cov kauj ruam-up regulator

Feem ntau cov pab kiag li lawm tsuas yog nyob rau hwj chim-down ua hauj lwm mus rau stabilize qhov kub thiab txias. Tuav voltage yuav tsum yog los ntawm 50-100%, los yog los ntawm 0-100%. Soldering hwj chim tej zaum yuav tsis txaus nyob rau hauv cov ntaub ntawv ntawm lub hwj chim mov 220 V los yog hauv qab no, e.g., ntau dua vypayat qub card yog tias tsim nyog.

Kev khiav hauj lwm voltage yog smoothed los ntawm electrolytic capacitor, nce nyob rau hauv 1,41 lub sij hawm thiab nourishes soldering hlau. Nruam lub hwj chim, rectified rau lub capacitor nce mus txog 310 V ntawm 220 V. Cov optimum lub hwj chim, lub cua sov kub yuav tsum tau txawm nyob rau hauv 170 V.

Haib soldering tsis tas yuav ua rau kom cov regulators.

Qhov yuav tsum tau rau lub tswvyim

Yuav kom sau tus neeg siv-phooj ywg hwj chim regulator rau ib tug soldering hlau nrog koj ob txhais tes, koj muaj peev xwm siv lub nto mounting txoj kev nyob ze ntawm lub qhov hluav taws xob. Nws yuav tsum tau me me-sized Cheebtsam. Hwj chim ib resistor yuav tsum tsis tsawg tshaj li 2 W, thiab lwm tus - 0.125 watts.

Hauj lwm ntawm lub tswvyim los txhim kho lub hwj chim regulator

Nyob rau hauv lub electrolytic capacitor C1 yog configured nrog VD1 choj cov tswv yim rectifier. Nws khiav hauj lwm voltage yuav tsum tsis txhob yuav tsawg tshaj li 400 V. Nyob rau hauv lub FET IRF840 regulator nyob downstream ib feem. Vim qhov no ntaus ntawv yuav siv ib tug soldering hlau los 65 W nrog ib tug radiator. Lawv yuav tsum tau rhuab saum toj no rau lub Desired kub, txawm nrog ib tug txo hwj chim mov.

tseem ceeb tswj transistor muab tso rau hauv lub nti DD1, ua los ntawm cov PWM generator uas nws zaus yog teem los ntawm capacitor C2. Parametric stabilizer mounted rau pab kiag li lawm C3, R5 thiab VD4. Nws muaj ib tug nti DD1.

Yuav kom tiv thaiv cov qhov tso zis transistor yog teem los ntawm lub inductance diode VD5. Nws yuav tsis tau teem caij yog hais tias tus hwj chim tswj ntawm lub soldering hlau yuav tsis tau siv nrog rau lwm cov hluav taws xob khoom siv.

Cov tau hloov qhov chaw nyob rau hauv lub controllers

DD1 nti yuav hloov los ntawm K561LA7. Rectifier choj yog ua los ntawm diodes tsim rau yam tsawg kawg nkaus tam sim no ntawm 2A. IRF740 ntaus ntawv yuav tsum siv raws li ib tug tso zis transistor. Lub Circuit Court tsis tau lub Symptoms, Yog hais tias tag nrho cov lus muaj tseeb, thiab yog hais tias nws twb tsis tau tso cai los ua ke uas tsis.

Lwm yam pab kiag li lawm rau dissipating voltage

Cia li mus rau lub hwj chim regulator Circuit Court rau soldering, ua hauj lwm rau symistors KU208G. Tag nrho cov ntawm lawv cov cunning nyob rau hauv lub condenser thiab lub neon teeb, uas yog hloov nws brightness, yuav pab raws li ib lub hwj chim taw qhia. Tau hloov - los ntawm 0% mus rau 100%.

Nyob rau hauv lub qhaj ntawv ntawm ib tug triac los yog thyristor qhov muag yuav tau mus thov KU202N. Qhov no yog ib tug heev ntaus ntawv muaj ib tug plurality ntawm cov phooj ywg. Nrog nws cov kev siv yuav tsum tau koom ua ke Circuit Court khiav hauj lwm nyob rau hauv ib tug ntau ntawm 50% mus rau 99% lub hwj chim.

Ferrite tub ntxhais los ntawm lub computer qaum yuav siv tau los ua ib cov voj them rov qab cov tau cuam ntawm switching lub triac los yog thyristor.

scaler qhia

Lub hwj chim regulator soldering dial gauge tau muab kev rau ntau dua kev nplij siab thaum lub sij hawm siv. Ua nws ib tug snap. Tsis Siv qub audio khoom yuav pab tau nrog cov kev tshawb fawb rau tej ntsiab. Devices yooj yim mus nrhiav nyob hauv lub zos ciaj uas muag nyob rau hauv txhua lub nroog. Zoo, yog hais tias xws li ib tug ib tug yog nyob rau hauv tsev ua tsis muaj dab tsi.

Piv txwv li, xav txog lub tseem ua ke rau hauv lub hwj chim regulator rau soldering qhia M68501 xub thiab numeric qhab nia, uas yog teev nyob rau hauv lub qub Soviet recorders. Feature chaw yog cov kev xaiv ntawm resistor R4. Yeej muaj mus khaws lub tsev R3 nyob rau hauv tas li ntawd, yog tias lwm qhov taw qhia siv. Ib tug tsim nyog yuav tsum muaj cai thaum uas tsis muaj hwj chim resistors soldering. Lub fact tias cov xub taw qhia yuav tso saib hwj chim txo los ntawm 10-20% ntawm lub sij noj soldering hlau 50%, i.e. tsawg tshaj li ib nrab.

xaus

Fais fab kev tswj rau soldering yuav sau, ua los ntawm lub teeb ntawm cov lus qhia thiab cov khoom nrog rau cov saum toj no piv txwv uas tau sib txawv circuits. Los ntawm zoo lo, flux thiab kub ntawm lub caij cua kub soldering zoo lom zem ntau nyob. Sophisticated pab kiag li lawm mus rau stabilize los yog elementary kev koom ua ke diodes yuav siv tau nyob rau hauv lub rooj sib txoos ntawm pab kiag li lawm tsim nyog los tswj cov khoom voltage.

Xws li yog lug siv nyob rau hauv thiaj li yuav txo thiab kom lub hwj chim nkag mus hauv lub caij cua kub ntawm lub soldering hlau nyob rau hauv ntau ntawm 0% mus rau 141%. Nws yog heev yooj yim. Muaj yog ib tug tiag tiag lub sij hawm mus ua hauj lwm rau voltages hauv qab no 220 V. Nyob rau hauv hnub no tus lag luam cov nyob rau ntawm zoo tsheb, nruab nrog tshwj xeeb ntawm lwm yam uas. Hoobkas pab kiag li lawm khiav lag luam tsuas yog nyob rau txo hwj chim. Cov kauj ruam-up regulator yuav tau sau koj tus kheej.
