Kodi mungapange bwanji oscillator ndi manja anu kuti muwotchere?

Chowotchera chowotchera ndizofunika kwambiri kuti zitsulo zikhale zofewa m'madera osiyanasiyana. Oscillator ndi othandiza kwambiri kuti ingagwiritsidwe ntchito palimodzi m'mafakitale ndi m'moyo wa tsiku ndi tsiku. Chombo cha oscillator ndi kutentha kwa arc. Pakalipano, chakudya choyaka moto chimapitirizabe ntchito. Oscillator yogwiritsidwa ntchito kawirikawiri ndizithunzithunzi za mtundu OP-240.

Popeza kutsekemera n'kofunika kwambiri m'magulu ambiri opanga komanso ntchito zapakhomo, kufunika kwa oscillator kumakhala kosangalatsa kwambiri. Sikoyenera kuigula konse. Oscillator ndi manja awo sikovuta kupanga. Izi zidzasowa zokhazokha zokhazokha ndi kusunga zomwe zikuperekedwa pansipa.

Mfundo yogwirira ntchito

Wogwiritsa ntchito osakaniza opangira mawotchi ndi manja anu omwe amagula ntchitoyo amagwiritsidwa ntchito pofuna kukhazikika bwino kwa arc. Nthawi zambiri ndi 50 Hz pamagetsi opangira 220 V. Pogulitsa, magawowa akhoza kuwonjezeka mpaka 150000-300000 Hz ndi 2500-3000 V, motero. Ndi opaleshoniyi, oscillator amapanga mapulaneti mpaka masikiti angapo a microseconds. Zomwe zimagwiritsidwa ntchito panthawiyi, pamene maulendo apamwamba omwe amatha kupita kumalo owotcherera, amachokera ku mphamvu yofanana - 250-350 W.

Kupanga

Ndi zizindikiro zoterezi, opangidwa ndi aluminium oscillator ndi manja awo ali ndi mphamvu zomwe zimagwirizana ndi kupanga zotupa kapena ntchito yokonza tsiku ndi tsiku. Ndi chithandizo chake, n'zotheka kusunga zitsulo zotayidwa ndi zitsulo zina.

Taganizirani zigawo za magetsi za oscillator:

• Kumanga;
• Zitsulo ziwiri zazingwe;
• Zosintha: zosavuta komanso zapamwamba;
• Dera losasuntha.

Dera lokhala ndi capacitor ndi high-frequency transformer limapangitsa kuti phokoso liziyenda bwino.

Kodi ntchito yamagetsi ndi iti?

Dera loyendetsa dera limeneli limapanga ntchito yofunika kwambiri yotetezera chipangizo chomwecho ndi kuwotcha antchito kuvulala kosiyanasiyana chifukwa cha magetsi. Mwinamwake, dera lamagetsi limatsegulidwa chifukwa cha fuseti yapadera. Zimatetezera.

Kugwiritsidwa ntchito kwa mapulogalamu ndi oscillator kumachitika molingana ndi ndondomeko yotsatirayi. Mpweya umaperekedwa kudzera mu transformer kupita ku capac capacitor. Kotero izo zimatsutsa izo. Mukamatsitsa kwathunthu, cappositor imamasula kuchotsa pakali pano pakamwa, komwe kumapangidwanso. Pakalipano, dera losasunthika ndi lofupika. Zonsezi zimayambitsa kusinthasintha malinga ndi lamulo la resonance. Koma nthawi yomweyo amatha. Nthawi yamakono yowonjezereka yamatsinje amatha kufika pa arc yowonjezera, kupyolera pa capacitor ndi coil.

Sitiiŵala kuti kutsekemera kachipangizo kogwiritsa ntchito kachipangizo kamene kumapangitsa kuti pakhale njira yapamwamba yowonjezera pamtunda, chifukwa cha zotsatira zake zapamwamba. Chifukwa cha kukana, pamodzi ndi kutseka kwa capacitor, oscillator amatetezedwa ku maulendo ang'onoang'ono.

Kodi njirayi ikuchitika bwanji?

Kuti apange oscillator ndi dzanja lake, mpweya wothamanga kwambiri udzafunika. Amafunika kuwonjezera mphamvu. Komanso simungathe kuchita popanda batani pa botolo la madzi otentha. Zimagwirira ntchito kudyetsa mpweya ndi phokoso la plasma-forming arc, komanso pofuna kuyendetsa chithandizo. Zonsezi zimateteza zitsulo kuchokera ku mpweya wa oxygen ndipo zimapangitsa kuti apange argon yeniyeni, momwe kutsekemera kwazitsulo kumachitika.

Ntchitoyi ndi yotsatira. Pambuyo pa kupanikiza kwa batani, kumangidwa kumene kumayambitsa maulendo othamanga kumawonekera. Pulogalamu yapamwamba ya voltage yotereyi imayankha izi. Mphamvu yamaginito imalengedwa kupyolera mu arc, kenako imasinthidwa ndi coil. Yotsirizirayi imapangidwa ndi kuthamanga ndi chingwe chodziwira.

Zojambulazi zili ndi zotsatira ziwiri - kuphatikiza ndi kuchepetsedwa. Zonsezi zimadutsa mu transformer. Komabe, choyamba chimapita kwa woyaka moto, koma chachiwiri - kuntchito. Pambuyo pa kupanikiza kwa batani, mpweya umayenderera kupyolera mu valavu kupita ku zotentha. Ichi ndi kuyamba kwa njira yowonjezera. Komanso oscillator iliyonse, kaya ndi fakitale kapena yokometsera, iyenera kukhala ndi capacitor.

Musanayambe kukonza zojambula zojambula nokha , muyenera kudzidziwitsa nokha masomphenya a mapangidwe ake. Ngati pali ngakhale chidziwitso choyambirira m'makina amisiri, izi sizingakhale zovuta. Kuwonjezera apo, zomwe zinachitikira kupanga ndi zofunika. Pamene mukuchita nokha, muyenera kukumbukira kuti mukuyenera kuyang'anira zodzitetezera. Pamene pali chiopsezo cha magetsi.

Kupanga njira

Pofuna kusungunula makamaka zida zowonjezera zitsulo zotayira, mungathe kupanga chofukizira chowotcha ndi manja anu. Chimodzi mwa ndondomeko zomwe zimagwiritsidwa ntchito kwambiri zimagwiritsidwa ntchito poyambitsa:

1. Chinthu choyamba chochita ndikusankha chitetezo chodalirika kuti chikhoze kuwonjezera kuchuluka kwa magetsi kuchokera ku chiwerengero cha 220 mpaka 3000 V.
2. Pambuyo pake, ife timayika phokoso lachitsulo.
3. Kenaka, gwirizanitsani chinthu china chofunikira - dera losasuntha lokhala ndi block capacitor lomwe limapanga maulendo apamwamba.

Ndizo zonse, oscillator ndi okonzeka. Mbali yaikulu ya dera la chipangizo ichi ndi dera lozungulira. A capacitor obwezeretsa ayenera kukhalapo pakupanga kwake. Dongosolo losasuntha, lomwe limaphatikizapo inductor ndi wogwidwa, ndilofunika kupanga mapulaneti. Ndiwothandizira, arc yowonjezera ikuwombera mosavuta.

Wogula kapena wopangidwa oscillator ndi manja ake akhoza kukhala pulsed ndi kupitirira. Koma chisankho chotsiriza sichigwira ntchito. Kuphatikizanso, chipangizo china chikufunika kuti chiteteze motsutsana ndi magetsi.

Malamulo opanga

Choncho, ngati chipangizocho chikagwiritsidwa ntchito pokhapokha pa moyo wa tsiku ndi tsiku, ndi bwino kupanga chogudubuza chowotchera manja ndi manja anu, popeza kugula kwake kuchokera kwa wopanga ndi wogulitsa kumakhala kotsika mtengo kwambiri. Kuwonjezera apo, muyenera kukhala ndi maluso kuti musonkhanitse zipangizo zotere komanso kudziwa zamagetsi.

Ngati mukufuna kutulutsa oscillator nokha, muyenera kumvetsera msonkhano wokhawokha, komanso kuti mukugwira bwino ntchitoyi. Ndiponsotu, chipangizocho chimayendetsedwa ndi magetsi. Ndipo popanda kusunga zodzitetezera, chiopsezo chovulaza ndi chachikulu. Muyenera kuyandikira msonkhano wa magetsi ndikugwiritsanso ntchito zigawo zomwe zili zoyenera pazochitika zawo. Ngati mutatsatira malangizowo onse, kupanga oscillator ndi manja anu sangakhale ovuta. Mukungofunikira zipangizo zonse ndi zipangizo zonse.
