Bwanji Mng'oma wa mphamvu yang'anira kwa soldering chitsulo? Mphamvu kulamulira kwa soldering ndi manja awo: chiwembu ndi malangizo

Zipangizo kusintha voteji mlingo aperekedwe ku zinthu Kutentha, hams nthawi zambiri ntchito popewa kulephera msanga wa soldering nsonga ndi khalidwe la soldering. Njira ambiri chifukwa owongolera mphamvu akupanga soldering masiwichi dvuhpozitronnye kukhudzana ndi zipangizo SCR anaika mu pachithandara. Awa ndi zipangizo zina kupereka angathe kusankha kufunika mlingo voteji. Today ntchito zikhazikiko amamwa ndi fakitale.

Zambiri mphamvu yang'anira Soldering

Ngati inu mukufuna kupeza soldering chitsulo 40 W 100 W ingagwiritsidwe ntchito pa dera triac BT 138-600. Iwo amagwira ntchito mwa kudula yoweyula sine. mlingo kukameta ubweya ndi Kutentha kutentha zikhoza kusintha ntchito resistor R1. Neon nyale akutumikira monga chizindikiro. Kuika si koyenera. Pa rediyeta waikidwa triac BT 138-600.

nyumba

Chiwembu lonse ayenera kuyikidwa mu chatsekedwa dielectric nyumba. Kudzikonza chipangizo kakang'ono sayenera bwanji chitetezo pamene ntchito. Onani kuti chipangizo umagwira ntchito ku gwero voteji a 220 V.

SCR mphamvu yang'anira Soldering

Mwachitsanzo, taganizirani chipangizo, cholinga kwa katundu Watts angapo mazana. Lamulo osiyanasiyana mphamvu oveteredwa chipangizo zimasiyanasiyana 50% kuti 97%. chipangizo amagwiritsa atagwira KU103V SCR panopa zosakwana milliampere wina.

Kudzera diode ndi VD1 momasuka pochitika zoipa theka-yoweyula voteji, kupereka theka la mphamvu okwana chitsulo soldering. Izo zikhoza kusintha VS1 SCRs panthawi iliyonse zabwino theka mkombero. zida ndi anazimitsa antiparallel diode VD1. SCR mwapamalo olamulidwa ndi mfundo. Jenereta amapanga nyemba athandizira pa ulamuliro elekitirodi ongokhala R5R6C1 dera liwulo nthawi ndi unijunction transistor.

Numeral chogwirira resistor R5 ndiyo nthawi ya HIV theka mkombero. Mphamvu ulamuliro chiwembu amafuna kutentha bata ndi bwino phokoso chitetezo chokwanira. Izi zikhoza shunted wotsogolera kusintha resistor R1.

unyolo R2R3R4VT3

Jenereta voteji nyemba kudyetsedwa kwa 7b ndi nthawi ya 10 MS, zooneka R2R3R4VT3 unyolo. Masana VT3 transistor ndi chinthu wosasunthika. Iwo adamulowetsa motsogozedwa iwowo. Mphamvu dera lomwe dissipates resistors R2-R4, adzakhala yafupika.

Galimoto mphamvu yang'anira kumaphatikizapo ndi capacitor S1KM5, resistors - MLT ndi R5 - SP 0.4. The transistor angagwiritsidwe ntchito kaya.

Board ndi nyumba kwa chipangizo

Pakuti khamu la chipangizo yabwino zojambulazo fiberglass gulu la mamilimita 36 m'mimba mwake ndipo 1 mamilimita wandiweyani. Pakuti choncho, mukhoza kugwiritsa ntchito zinthu iliyonse, monga mabokosi pulasitiki kapena milandu zakuthupi ndi kutchinjiriza wabwino. Muyenera m'munsi akumvera miyambo foloko. Chifukwa chaichi zojambulazo angakhale kuti solder awiri mtedza 2,5 M kuti zikhomo mwamtundu gulu nyumba pa msonkhano.

Kuipa SCRs KU202

Ngati mphamvu ya yaing'ono soldering chitsulo, malamulo n'chotheka mu yopapatiza theka mkombero. Munthu kumene kupirira SCRs voteji osachepera pang'ono poyerekeza katundu panopa. Kutentha bata sizingatheke pogwiritsa ntchito ngati mphamvu yang'anira kuti soldering.

Chinthu mmwamba yang'anira

zipangizo kwambiri yekha pa ulamuliro pansi ukugwira ziziyenda kutentha. Kuthana voteji kungakhale kwa 50-100%, kapena kuchokera 0-100%. Soldering mphamvu mwina osakwanira vuto la magetsi 220 V kapena pansipa, mwachitsanzo, wamkulu vypayat khadi akale ngati n'koyenera.

Opaleshoni voteji ndi ankawachotsera ndi capacitor electrolytic, adakulabe mu nthawi 1,41 ndi chakudya chitsulo soldering. Wopitiriza mphamvu, kudzatha pa capacitor ukufika 310 V pa 220 V. Mphamvu akadakwanitsira, ndi Kutentha kutentha akhoza zopezera ngakhale pa 170 V.

Wamphamvu soldering safuna kuonjezera owongolera.

Mbali wofunikila chiwembu ndi

Kusonkhanitsa wosuta-wochezeka mphamvu yang'anira kuti chitsulo soldering ndi manja anu, mungathe kugwiritsa ntchito njira pamwamba ogwiritsa pafupi kubwereketsa lapansi. Pamafunika zigawo ang'ono-kakulidwe. Mphamvu umodzi resistor ayenera kukhala osachepera 2 W, ndi ena - 0.125 Watts.

Kufotokozera za chiwembu cha kusintha mphamvu yang'anira

Mu capacitor electrolytic C1 ndi kukhazikitsidwa ndi VD1 mlatho athandizira rectifier. opaleshoni ake voteji ayenera kukhala osachepera 400 V. Mu FET IRF840 yang'anira ili gawo pambuyo pake. Popeza chipangizo ichi mungagwiritse ntchito chitsulo soldering kuti 65 W ndi Redieta a. Iwo akhoza usavutike pamwamba kutentha akufuna, ngakhale ndi chakudya kuchepetsedwa mphamvu.

kiyi kasamalidwe transistor anaika pa Chip DD1, umatulutsa jenereta PWM amene pafupipafupi walembedwa ndi capacitor C2. Parametric stabilizer wokwera pa zipangizo C3, R5 ndi VD4. Iye ali Chip DD1.

Kuteteza transistor linanena bungwe amamasulidwa ku inductance diode VD5. Izo sizingakhoze anapereka ngati kulamulira mphamvu ya soldering yachitsulo kugwiritsidwa ntchito ndi katundu wina magetsi.

Kutheka kwa kuchotsa mbali mu opha ndi

DD1 Chip akhoza m'malo ndi K561LA7. Rectifier mlatho zopangidwa diodes lakonzedwa kuti panopa osachepera 2A. chipangizo IRF740 angagwiritsidwe ntchito ngati transistor linanena bungwe. dera sayenera ubwenzi, ngati zonse ali olondola, ndipo ngati sankandilola zolakwa msonkhano.

zotheka zipangizo zina dissipating voteji

basi ku dera mphamvu yang'anira kuti soldering, ntchito pa symistors KU208G. kuchenjerera awo onse mu condenser ndi nyale Neon, zomwe zikusintha kuwala kwake, angathe kutumikira monga chizindikiro mphamvu. N'zotheka kusintha - kuchokera 0% mpaka 100%.

Popeza ndi triac kapena thyristor mababu ingagwiritsidwe KU202N. Izi ndi chipangizo sizachilendo kukhala kuchuluka kwa anzawo. Ndi ntchito yake anasonkhana dera kugwira ntchito mu osiyanasiyana mphamvu 50% mpaka 99%.

Ferrite pakati pa chingwe kompyuta angagwiritsidwe ntchito kupanga kuzungulira kuti abwezere kusokonezedwa mwina kusintha kwa triac kapena thyristor.

scaler chizindikiro

Mphamvu yang'anira soldering oyimba n'zotsimikizira akhoza Integrated chitonthozo chachikulu pa ntchito. Khalani ndi chithunzithunzi. Makuponi akale zida zomvetsera angathandize kufunafuna zinthu zimenezi. Zipangizo zosavuta kupeza misika ya m'deralo mu mzinda uliwonse. Chabwino, ngati wina ali kunyumba kuchita kanthu.

Mwachitsanzo, kuganiza kuti kuphatikiza mu mphamvu yang'anira kuti soldering chizindikiro M68501 muvi ndi zizindikiro M'ndandanda, amene anaika mu zojambulira akale Soviet. Mbali inachitikira kusankha resistor R4. Ndithu kukatenga unit R3 kuwonjezera, ngati chizindikiro china. An bwino yoyenera ziyenela kuyan'anidwa otsika mphamvu resistors soldering. chakuti muvi chizindikiro angasonyeze kuchepetsa mphamvu mwa 10-20% pa leni mowa soldering chitsulo 50%, i.e. zosakwana hafu.

Pomaliza

Mphamvu kulamulira kwa soldering akhoza amatengedwa, motsogozedwa ndi wa malangizo ndi nkhani ndi zitsanzo pamwambapa zotheka madera osiyana. Kuyambira solder wabwino, kamwazi ndi kutentha kwa Kutentha mchitidwe soldering khalidwe kwakukulukulu zimatengera. zipangizo yotha ziziyenda kapena pulayimale kusakanikirana diodes angagwiritsidwe ntchito mu msonkhano wa zipangizo zofunika zonse voteji ukubwera.

makina onga ankagwiritsa ntchito kuti tisakhale ndi kuonjezera mphamvu yopezeka kwa Kutentha mchitidwe chitsulo soldering mu osiyanasiyana kuchokera 0% kwa 141%. Ndi yabwino kwambiri. Pali mwayi weniweni ntchito voltages pansipa 220 V. Mu msika lero kupezeka kwa magalimoto quality, zida ndi amazilamulira wapadera. Factory zipangizo ntchito kokha pa wotsikirapo mphamvu. Chinthu mmwamba yang'anira adzakhala ndi kusonkhanitsa nokha.
