Vuam rectifier thiab nws cov ntaus ntawv

Nws yog ib qho nyuaj rau xav txog tej yam kev tsim kho kev lag luam los yog machinery tsis Vuam. Nws yog muab faib ua ob hom: direct thiab alternating tam sim no.

Siv DC muab ib tug ntau dua zoo weld. Qhov no yog vim lub tsis muaj pes tsawg tam sim no, thiab chaw pib lub arcing yuav ruaj khov, thiaj li spattering los ntawm cov burning ntawm lub electrode, cov hlau ntxaum allergic yog tau, nyob rau hauv zoo weld zog zog.
Nyob rau hauv tas li ntawd, cov ntaub ntawv xws li cam khwb cia hlau, high-hlau steels, npib tsib xee-raws li alloys, tooj liab, titanium, yuav siv tau rau Vuam xwb ib tug tib neeg tam sim no.

Kom hloov lub alternating tam sim no muaj ib zaus ntawm 50 Hz, ib qhov siv vuam rectifier. Nws yuav siv tshwj xeeb semiconductor li qub thiab tswj pab kiag li lawm nyob rau hauv lub transformer. Muaj ntau hom xws khoom. Txhua yam ntawm lawv muaj nyob rau hauv nws cov qauv ib tug daws kom tiav chav tsev, ballast tsev tiv thaiv thiab instrumentation thiab hwj chim transformer.

Vuam rectifier yog siv rau phau ntawv arc vuam thaum lub electrode melts thiab pulsed arc welding, nyob rau hauv uas lub impulse pab nyob rau hauv kev sib cais ntawm cov hlau electrode hlau mob.

Rau kom yooj yim, ib tug tshwj xeeb cov neeg kho tshuab welding rectifier welding VD transformer hom, muaj cov chaw taws teeb hom mus. Tej converters yog tsiag ntawv los ntawm thawj kev daws teeb meem:

• nyob rau hauv tib ntau yam rau Vuam tam sim no hloov yog tus;
• npoo rooj noj magnetic shunt kab rov tav tsim, muab txhua yam kev hloov ntawm lub weld, nws muaj ib tug yooj yim qauv;
• transformer windings no yog ua los ntawm tooj liab;
• tsis muaj tsiv kauj;
• txias nyob rau hauv cov huab cua;
• ignition yog yooj yim tau, lub arc yog ruaj khov;
• rwb thaiv tsev chav kawm ntawv - H;
• tam sim no connectors yam xyuam xim thiab ceev ceev qhib;
• ib tug vuam tej yam kev mob editing rectifier ntawm no hom yuav yooj yim rau koj tsiv tawm.

Tej zaum, nyob rau hauv tsev muaj ib tug yuav tsum tau ua vuam ua hauj lwm. Nyob rau hauv no qhov teeb meem no muaj ob txoj kev xaiv - yuav npaj txhij-ua tshuab los yog ua rau lawv tus kheej vuam rectifier nrog lawv ob txhais tes.

Lub ntsiab caij yog ib qho improvised rectifier transformer rau converting AC kab voltage thiab muab cov kev tsim nyog loj thiab zoo tshaj ntawm cov weld tam sim no. Txuas nws yog ua tau rau network nrog voltage ntawm 220 V, thiab cov qhov tso zis nws yuav tsum tau muab 40-70 V.

Tom ntej no mus cov terminals ntawm lub transformer yuav tsum solder lub hwj huam qaum txog 2.5 square millimeters nyob rau hauv lub cheeb thiab ib tug ntev ntawm hais txog 5 meters, rau ib qho yooj yim zog ntawm tus vuam siv lub tshuab. Cov hlau yog zoo dua siv ib tug muab ob npaug rau kev rho tawm.

Cov theem tom ntej - kev npaj rau welding cables. Rau lub hom phiaj no nws yog ib qho zoo rau siv mos hlau nrog roj hmab rwb thaiv tsev, tsawg kawg yog ob meters nyob rau hauv ntev. Nyob rau ntawm ib kawg ntawm cable fastened clothespin "masses" (tej zaum tsheb "sib zog" yuav siv tau), nyob rau lwm yam cable - electrode yas dhos.

Tam sim no koj yuav tsum muab tso ua ke ib vuam rectifier. Los ntawm no nws yog nyob ntawm seb yuav ua li cas lub ntaus ntawv yog yooj yim rau lub lag luam. Nyob rau hauv lub lag luam, nws yuav tsum tau rhuab, ces lub vaj tse yuav tsum tau muab nrog qhov quav qhov. Rau yooj yim thauj rau lub vaj tse ntswj kom nruj cov kov thiab teem lub log. Tau pw ntawm tej thiab cables rau nruab ntxiv cheebtsam hauv daim ntawv ntawm hooks, txuas, nkhaus.
